1.0 INTRODUCTION

The Department of Defence (Defence) engaged Golder Associates Pty Ltd (Golder) to undertake a

Preliminary Site Investigation (PSI) of the RAAF Base Scherger (Queensland), Defence property 1218. The

PSI focussed specifically on the investigation of the contaminant group per- and polyfluoroalkyl substances

(PFAS).

1.1 Poly- and Perfluorinated Substances (PFAS) Per- and polyfluoroalkyl substances (PFAS) are internationally commonly used chemicals in the production of stain repellents, lubricants, fire retardants and suppressants, including Aqueous Film Forming Foams (AFFF), and pesticides, and as industrial surfactants and emulsifiers (US EPA, 2005). AFFFs are ‘Class B’ fire-fighting foams used to prevent or extinguish flammable liquid fires. AFFF forms a barrier that inhibits oxygen from feeding the fire, while limiting volatilisation of flammable vapours from fuels.

Historically (from the 1970s), Defence used AFFF (commonly 3M LightwaterTM) that contained

perfluorooctane sulfonate (PFOS) and perfluorooctanoic acid (PFOA). From 2004, Defence commenced

phasing out legacy AFFF across the Defence Estate. The chemical structures of PFAS make them extremely

resistant to breakdown. As a result, they are persistent once released to the environment. On the basis of its

physical properties, PFOS is essentially non-volatile, and would not be expected to evaporate from water

(US EPA 2005). Infiltration of water could carry PFOS/PFOA into the subsurface or into groundwater. In soil-

water mixtures, PFOS has a strong tendency to remain in water due to its solubility.

1.2 Background

Defence has been undertaking a program of works to consider the potential for PFAS contamination relating

to the use and storage of legacy AFFF products across the Defence Estate. As part of this program, it was

identified that a PSI was required at RAAF Base Scherger to address the uncertainties associated with the

use of AFFF and the sensitivity of potential receptors. The findings from this PSI will be used by Defence to

consider the need and program priority for further detailed site investigation.

1.3 Key Findings from the Data Gap Assessment

A summary of the key findings of AFFF use from the Data Gap Assessment (Golder, 2016) were:

Fire emergency training was undertaken at the Base during an exercise in 2005, involving generation of

foam. The exact location of training could not be confirmed but was considered likely by the RAAF

personnel to be in areas aircraft occupy and operate, including taxiways and hangers. Fire trucks were

parked in Building 7 during the 2005 exercise.

Waste AFFF (until 2011) from servicing of fire extinguishers was disposed to ground at the locations

where extinguishers stored (Ordnance Loading Areas (OLAs), Hangers, General Purpose Apron (GPA)

and areas where fuel stored). From 2011 to 2014 these were centralised to OLA3, OLA8 and GPA.

Groundwater is extracted at the property for use. Likely groundwater extracted off-property.

Ephemeral streams on the property.

No known emergency use of AFFF at the property was reported by the Defence site personnel.

No monitoring results were available as part of the data gap assessment.

1.4 Objectives

The objective of the scope is to complete a PSI in accordance with the National Environment Protection

(Assessment of Site Contamination) Measure (ASC NEPM) (NEPC, 2013) including the assessment of

specific data gaps for the property and the collection of environmental samples.

The PSI is limited to use, storage and waste disposal associated with AFFF products and associated

potential PFAS contamination at the property.



An additional objective of the PSI was to obtain information required for the proposed priority re-

categorisation with respect to the following:

Significance of AFFF use:

Confirmation of potential source areas and additional understanding of AFFF storage, use and

waste disposal.

Obtain environmental data for PFAS in soil, sediment, surface water and groundwater at or down-

gradient of identified source areas to further the understanding of the significance of AFFF use.

Sensitive Receptors:

Provide greater understanding, without external stakeholder engagement, of potential sensitive

receptors of contamination. In particular, consideration of human receptors and receptors

associated with the human food chain.

For clarity the objective of the PSI is not to assess the nature and extent of PFAS contamination (if present).

As such, the understanding of PFAS contamination at the completion of the PSI will be preliminary and there

is likely to be data gaps associated with initial Conceptual Site Model developed. Given the preliminary

nature of the investigation and the objective to collect sufficient information for re-categorisation, the

investigation was completed within the boundaries of the property and not off-property.

Given the specific objectives of the PSI the scope of services outlined does not include all aspects of a PSI

that would be undertaken if the complete contamination history was to be considered, such as title history,

searches of government/local council records etc., as these type of searches were considered unlikely to

provide additional information required to achieve the project objectives than what would be determined from

the scope undertaken. In addition, given the focus of the investigation is the historic use of AFFF and

potential PFAS contamination, no analysis of non-PFAS contaminants was included in the scope.

During the reporting timeframe of the project, Defence adjusted the scope of work to remove the re-

categorisation task as it was no longer required as part of the on-going Defence PFAS Program

development. Notwithstanding this change, the purpose of the PSI was primarily to gather additional

information to develop the understanding of the PFAS conceptual site model (CSM) and identify the issues

that may require further investigation.

2.0 SCOPE OF SERVICES

The following tasks were completed for the scope of services:

Obtain, review and consolidate existing reports and information relating to use, storage and waste

disposal of AFFF, environmental conditions (geology/hydrogeology etc.), including:

Data Gap Assessment (Golder, 2016).

Reports held on the Defence Contaminated Site Register (CSR).

Follow up interviews with Defence personnel as required (including identification of personnel not

interviewed as part of the Data Gap Assessment).

Review existing investigations reports to confirm the presence of available monitoring well locations,

either located in the immediate vicinity of potential source areas or down-gradient of potential source

areas.

Obtain and review of publically available historical information for the Property including:

Historic aerial photographs.

Topographical, soil and geological maps.

Undertake site reconnaissance to gain an understanding of the existence and use of water supply bores

in the vicinity of the property. This included review of current land use where registered bores are



located. At this stage of the project life-cycle, this PSI did not include engagement with external

stakeholders to confirm water use. However, as part of the interviews with Defence personnel further

understanding of the use of groundwater and surface water off-property was sought.

Undertake site inspections to ground truth additional information obtained from the desktop reviews and

interviews. Provisionally select investigation locations prior to preparation of the Sampling Analysis and

Quality Plan (SAQP).

An initial Conceptual Site Model (CSM) was developed, based on the available information. The CSM

identified potential sources, possible pathways for contaminant migration and potential receptors for

PFAS contamination. Based on the initial CSM, the targeted sampling program was presented in a

SAQP (Golder 2017). The SAQP provided justification for the proposed targeting sampling locations,

media to be sampled and analytical program. The SAQP also included details on the methodologies

employed across the sampling, analytical and quality aspects of the program to ensure that the data

obtained is of a quality required for the objectives of the PSI. Field QA/QC was implemented in

accordance with NEPM procedures and particular attention paid to avoiding PFAS cross-contamination

from sampling methods or equipment. The CSM was subsequently refined based on the results of the

investigation program and presented in this PSI report.

Collection of soil samples from six soil bores and conversion into groundwater monitoring wells at the

following locations:

General Purpose Apron (BH022)

Fire Station Building 7 (BH023)

Ordnance Loading Area 3 (OLA3) (BH024)

Ordnance Loading Area 8 (OLA8) (BH025)

South-western portion of site on access road to Sewage Treatment Plant (BH026)

North-western portion of site near site boundary (BH027)

Soil samples were collected between 0.5 and 1.0 m below ground level (m bgl), and a deeper sample

targeting just above the water bearing zone to a total depth of between 7.25 m and 16.75 m.

Groundwater was sampled from four existing groundwater monitoring wells and the six new wells. The

existing monitoring wells targeted the shallowest groundwater unit at the following potential source

areas:

Aviation Fuel Farm (RAAFSGR10)

Central Power Station (RAAFSGR14)

Motor Transport Facility (RAAFSGR18, RAAFSGR19)

Water for Base water supply was sampled from the Water Treatment Plant (WTP) pre-treatment

(W002) and post-treatment (W001). Groundwater is used for water supply.

Where accessible, sampling and analysis of the identified surface water streams. This involved the

collection of 6 surface water samples. In addition, 13 sediment samples were collected from natural

and formed surface drainage features around the Base.

Samples were analysed at ALS Environmental (primary laboratory) and Eurofins MGT (secondary

laboratory), using National Association of Testing Authorities (NATA) accredited methods.

Preparation of a PSI report in accordance with the requirements of ASC NEPM (NEPC, 2013).

Updating of the Defence CSR for each property with the results of the PSI.

The site inspection and field investigation scope were completed in March and May of 2017 respectively.



3.0 SITE DESCRIPTION

3.1 Site Identification

RAAF Base Scherger is within the Cook Shire and is located in Mission River, approximately 26 kilometres

east of Weipa in Cape York, Queensland. The Base, containing the airfield core area, is approximately

5,500 hectares (ha). The Base property lies north and south of the Peninsula Developmental Road (PDR). In

the initial Environmental Management Plan prepared by GHD for the Base (GHD, 1998), the total airfield

buffer area is about 13,000 ha which extends from Mission River in the north to Marmoss Creek in the south

(GHD, 1998).

The site location is illustrated in attached Figure 1.

3.2 Current Site Use

RAAF Base Scherger is a “bare base” staffed by limited personnel. While the base has facilities to cater for

400 personnel in fixed accommodation, 1000 personnel in tent lines, it is typically staffed by four Air Force

personnel who are responsible for caretaker duties. RAAF Base Scherger was opened in 1998.

The property contains accommodation facilities, administration buildings, fuel storage bunkers, hanger

space, munitions priming and storage, sewage treatment plant, water treatment plant and landfill. A primary

runway is approximately 3km long and associated taxiways are located in the north eastern portion of the

property.

Figure 2 provides a summary of the key features relevant to this project referenced in this report.

The land parcel reserved for the Base also includes an area south of the Peninsula Development Road as

illustrated in Figure 1. During the course of this PSI it was established with Defence personnel that Defence

use of this land was very limited (no infrastructure) and that therefore testing or servicing of fire equipment

was considered unlikely.

The features, facilities and areas of RAAF Base Scherger are presented on Figure 2.

3.3 Surrounding Land Use

Land tenure of the Weipa region is mostly Crown land subject to mining leases and pastoral leases which

are mainly cattle stations on unimproved natural pastures.

Surrounding land use includes the following:

North – The Mission River and associated flood plains, generally scrubland.

East – Ephemeral streams flowing into Mission River and scrubland.

South – The Peninsular Developmental Road. South of the Peninsula Development Road, Defence

have further land holdings south of which are bushland and streams flowing towards the Embley River.

West – Streams feeding into the Mission River and Rio Tinto’s eastern Weipa bauxite mining

operations. A residential accommodation camp occupied by the indigenous Peppin1 community is

located between the western boundary and the mining operations.

Various recreational activities occur in the region, including trail-bike riding, shooting, camping and fishing.

3.4 Review of Defence Contaminated Sites Register

The Defence Contaminated Sites Register lists five contaminated sites within the Scherger Base. The nature

of the contamination is related to hydrocarbon contamination associated with the storage of fuel and waste

oil products at the motor transport facility, central power station, aviation fuel farm, sewage treatment plant

pump shed, airfield lighting power centre and AVTUR storage facility.

1 The spelling of Peppin varies between sources and may be described as Peppin, Pappan or Peppan, This report faithfully transcribes the spelling from sources and the names should be considered interchangeable



The CSR was last updated in 20/06/2014. There are no entries in the contaminated sites register associated

with PFAS compounds.

The primary source areas list in Table 1 which are the subject of this PSI are associated with the following

contamination issues:

3.5 Historical Aerial Photographs

Given the remote location and relatively recent mining expansion in Weipa, historical aerial photography

prior to 1988 is limited. Historical aerial imagery for 1969 was sourced from Queensland’s Department of

Natural Resources and Mines (DNRM) for review. Images from 1988 to 2002, 2005 and 2013 were observed

via Google Earth. Copies of the aerial photographs referenced above are included in Appendix C.

The aerial photograph review was conducted to establish a general history of the development of the

property and surrounding area, and to the extent possible (given photograph quality and scales) consider

fire-fighting training areas. This review is summarised in Table 2.

3.6 Site Inspection & Desktop Preparations

An inspection of the Scherger Base and surrounding area was conducted on 7 March 2017. The following

activities were undertaken to develop an understanding of the known former uses of AFFF on the property,

and current use of surface water and groundwater both on and off site:

Interview of Defence identified personnel regarding AFFF site activities and information on water use on

and around the site. Personnel included:

Sergeant Graeme Whitaker who has been posted at RAAF Base Scherger since January 2017 and

therefore had limited knowledge on the historical usage of AFFF.

As part of the preparation for the site visit, some additional information was supplied by Warrant

Officer (WOFF) Brian Hughes. WOFF Hughes had been present at the previous site visit (June

2016) and has a longer tenure with various postings to Scherger (including being on Base during

the Exercise Kakadu in 2005).

Brief discussions were also held with Defence Contractors working on base during the time of the

inspection, including:

The representative from Lewie Fire had been working at Scherger for approximately 4 years.

The Enviropacific representative was a former Defence member until 2016 (Luke Spottiswood)

who had worked at Scherger since 2014 in the care and maintenance team.

During the site inspection, identified AFFF source areas were visited and the logistics of sampling at

each location were considered. In addition, the drainage pathways from each AFFF source area were

reviewed. The presence of Croton Hirtus, an invasive weed was also considered to design sampling

works that would not cross-contaminate parts of the property not impacted by Croton Hirtus.

3.7 Water Supply

An understanding of onsite water use was developed based on discussions with Sergeant Whittaker, the

Lewie Fire Contractor, and general observations made during the site inspection.

Bore water is extracted on Base, treated and subsequently used for a range of purposes. Until second half of

2016 treated bore water was used for onsite drinking water supply. Bore water is the current source for

domestic water supply including showers, laundry and all other on-Base purposes.

The water treatment plant is located south of the Motor Transport Facility and north-west of the

Accommodation Camp. Extraction bores supplying this plant are located in the apron surrounding the plant

and access road to plant. Four bores have been in operation at this location. Bores 1 and 2 were

decommissioned in approximately 2011 after the bore casing collapsed. Bores 3 and 4 were reported to be

still operational and were installed in approximately 2011. The Lewie Fire Contractor indicated in March

2017 that a new extraction bore is planned for installation in the water treatment plant apron area.

Additionally, it was reported that another bore was installed at the accommodation camp. The history of its

use could not be confirmed and existing site staff had no knowledge of it being operated.

Offsite indigenous camps have access to both bore and surface water as the primary water source. A

summary of on and off property surface water and groundwater use is provided in Section 4.4.3 and 4.4.4.

3.8 Other Information Sources

Other searches usually conducted as part of a PSI (for example a Certificate of Title search) were not

undertaken as it was considered that they would either contain limited beneficial information with respect to

potential AFFF use and/or would not be available for commonwealth lands, such as historical title

Information from a number of sources, including previous site investigations and public reports on regional

information were reviewed to establish the environmental setting of the site. Knowledge of the environmental

setting provides an initial understanding of the potential PFAS migration pathways and the sensitivity of the

receiving environment.

4.1 Climate

The nearest Bureau of Meteorology (BOM) weather station is Weipa Aero (Station 027045), located

approximately 15 km south west from the Base. The site has been active since 1941. The climate statistics

outlined in this section are based on data between 1992 and 2017.

Weipa is part of Australia’s northern tropics, a climate dominated by hot, wet, monsoonal summers and dry,

relatively cool winters. Weipa Aero Station reported daily maximum average temperatures are between

31.0°C and 35.6°C year round, with annual overnight minimums averaging between 18.7°C and 24.2°C.

The Weipa area has an average annual rainfall of 1,932 mm. Rain occurs on an average of 71 days of the

year. Rainfall shows seasonal variation throughout the year, with the approximately 85% of the mean annual

rainfall in December, January, February and March. The maximum number of rain days per month is 15,

occurring in January. The lowest mean monthly rainfalls and rain days occur in July (0.3 days).The annual

evaporation is greater than the annual rainfall, indicating a water deficit in the area.

Annual average wind directions are predominantly from the south east or east in the morning, and vary from

the south east, east or west in the afternoon (BOM, 2017).

4.2 Topography

The surface elevation rises from 20 m AHD in the west, north and east of the runway to up to approximately

50 m AHD in the vicinity of the runway in the north-east of the Base. South-east of the airfield area, the

property rises up to approximately 45 m AHD towards the Peninsula Developmental Road. Further south of

the Peninsula Developmental Road, the topography rises up to an elevation of 100m AHD forming a plateau,

locally known as the Weipa Plateau.

The property is characterised by a ridge which is oriented northwest - southeast on which the 3km runway for

the Base is constructed, and undulating hills and valleys, through which ephemeral streams flow. The ridge

peaks at approximately 50 m Australian Height Datum (AHD). North, northeast, west and southwest of this

ridge are tributaries and minor gully flows that enter the tidally affected Mission River to the north. South and

southeast of the Base is the Peninsular Developmental Road.

4.3 Soil and Geology

4.3.1 Soil

The 1:250,000 map Soils of the Cape York Peninsula, Far North Queensland, indicates the surface soils are

likely to comprise deep gradational or uniform yellow massive soil with ferruginous or magnaniferous nodules

formed or laterised remnants of the Bulimba Formation.

4.3.2 Acid Sulfate Soils

On-line acid sulfate soil (ASS) mapping hosted by the Australian Soil Resource Information System (ASRIS)

was reviewed. The ASRIS mapping is based on existing data sets which have been converted to a national

classification system (ASRIS 2011). ASRIS ASS mapping indicates that there is extremely low probability of

acid sulfate soils occurring in the region.

4.3.3 Regional Geology

Regional mapping (1:500 000) indicates the Base is situated on Tertiary aged stratified units including

volcanic and metamorphic rock. The majority of the Base is indicated to be underlain duricrusted palaeosols

at the top of deep weathering profiles including ferricrete and silcrete, duricrusted old land surfaces.

Aluminous laterite may be present, including bauxite with sandy “A” horizons, deep weathered furukun

surface. Geology in the southern end of the Base is mapped as Paleocene-Oligocene Sediments of

sandstone, mudstone and conglomerates.



4.3.4 Local Geology

Extensive drilling and geological logging has been conducted during the installation of 14 pre-existing

groundwater observation bores across the property and six additional wells installed for this investigation. (A

summary of groundwater observation bores at the Base is provided in Section 4.5.2.2).

Bore logs show the surface soils form of a horizon of ferricrete, described as sandy clayey gravel, silty clay

or silty sand. These shallow horizon is cemented with bauxite nodules increasing to gravels to

approximately 1.2 m depth, forming a resistant duricrust. The area around the runway is expected to be

underlain by fill material.

Underlying the ferricrete is sand of the Bulimba Formation, with intermittent bands of clayey sand, clayey

gravelly sand and silty sand, varying to sandy clays in some parts of the Base. White sand and kaolin clay

clasts are present at various depths across the Base: from 19 m depth at BH022 at GPA, and with red

mottling at BH023 from 13.5 m at Building 7 and from 10 m in the lower valley on western boundary at

BH027.

Registered bores in the vicinity installed for Comalco (now Rio Tinto) indicate the second layer of sand of the

Bulimba Formation is 5 to 8 m thick and extends to 25 m in places (Refer to registered bore records in

Appendix E). GHD (1989) found in some cases the sandy aquifer was not present rather, sandy clay only.

The onsite geology is broadly summarised in Table 3.

4.4 Hydrology

There are several surface water features associated with the property area. The Base EMP (GHD, 1998)

describes six spring sites of significance to Aboriginal people with interest in the land are located on and in

close proximity to the Base (GHD, 1998).

The locations of the springs have been identified in prior reporting (GHD, 2002):

Springs 1, 2, 4 and 6 are located within the Base fence line

Spring no. 5 is located just outside the south-western boundary fence

Spring no. 3 was not mapped.



The Mission River is located approximately 4.5 km north and a number of the natural springs onsite flow into

ephemeral tributaries and gullies that feed into this river (QLD Globe, 2017).

In a report documenting the outcomes of environmental monitoring for EMP compliance in 2001, GHD

reported that regular monitoring of groundwater bores installed throughout the Base in 1988 indicates that

the aquifer responds rapidly to local rainfall. Discharges occur naturally at springs and in watercourses

within the airfield buffer area boundary. (GHD, 2001).

Minor streams flowing at the southern extent of the Base (south of the PDR) drain to the Embley River

located approximately 2.4 km south west of the site. These flows are as indicated on Figure 2.

Drainage onsite is dominated by large engineered drainage channels that drain much of the hardstand area

on the south western watershed. This drainage is focused into a retention basin, before it’s discharged into

the southwestern tributaries of the Mission River. The water within the drainage lines on-site is not known to

be collected or used for any purposes such as irrigation or stock watering.

Salinity of the regional watercourses (Gulf Rivers zone) have been described in the Queensland Water

Quality Guidelines (QLD DEHP, 2013) as a moderate salinity zone.

4.4.1 Site Surface Water Drainage

The formed drainage network at the Base generally runs in a north-south direction and later meets tributaries

of the Mission River. The Mission River is a large water body which flows westerly discharging into the Gulf

of Carpentaria.

The formed drainage network generally follows the natural topography. Appendix D provides a detailed

topographic map of RAAF Base Scherger (GHD, 2001) with the location of natural springs.

Drainage generally associated with the key AFFF source areas (Section 6.0) flows in southerly direction and

the drainage channels join and discharge to a retention basin (asset reference 409), located centrally onsite,

immediately south of the main site access road. Releases from the retention basin are directed in a south to

south-easterly direction (refer topographic and drainage map, Appendix D) entering a tributary of the

Mission River.

Due to the extensive wet season in Cape York, the drainage channels and retention pond have been

designed and constructed for significant volumes of water and are of an earthen construction (unsealed).

The retention pond has been designed to settle water and then allow a more controlled release of water.

This is likely to result in the retention pond being a depositional environment for any sediments (and

associated contaminants bound to the sediments) moving in the stormwater.

Historically, a small dam (known as “Blue Lagoon) was constructed onsite for use in the construction of the

Base (prior to 1998) for water supply for dust suppression. The dam was subsequently drained and no

longer used as a permanent water storage body.

4.4.2 Irrigation

The property contains a number of irrigated areas including the gardens and grassed areas at the residential

homes on Base, the dog yards and the accommodation camp on the Base.

Based on the discussions held with base management, it is understood that irrigation water is sourced from

treated bore water extracted and treated on site at the water treatment plant located in the southern portion

of the Base (refer Figure 2).

4.4.3 On-property Surface Water Use

There is no use of water from the on-property surface water drainage lines.



4.4.4 Off-property Surface Water Use

Peppin Elders provided WOFF Hughes with information about the current water supply at the Peppin

Indigenous Camp in early 2017. It was understood from the Elders that the camp has not been used

recently as the septic sewage system has been backing up. When the camp is in use, bottled water or

surface water from the nearby creek is collected for water supply.

The extent of recreational activities on the Mission River for recreational activities (either water sports or

fishing) is not confirmed.

4.5 Hydrogeology

4.5.1 Regional Hydrogeology

The baseline hydrogeological study completed in advance of the Base construction provided a foundation

study of the groundwater resources in the locality of the property (GHD, 1989).

Key findings from this study (which have been reiterated in subsequent reports prepared by GHD) included:

The groundwater resources of the Bulimba Formation have been used extensively for the supply of both

industrial and domestic water to the mining operations and Weipa town.

The principal shallow aquifer used is the sandy horizon 3 m to 14 m thick which occurs approximately

6 m to 13 m below ground surface.

The principal shallow aquifer is considered to be an unconfined horizontal aquifer system which is

recharged annually by downward infiltration into the bauxite zones overlying the sandy member (GHD,

1989). This finding was corroborated by Maunsell (2005) with the identification of bauxite / ferricrete

from ground surface to approximately 5 m or 6 m depth, underlain by the shallow sand aquifer to

approximate depths of 11 or 12 m.

An additional deep aquifer is present in the underlying Garraway Beds at a depth of about 900 m where it

forms a confined artesian source (GHD, 1989).

4.5.2 Local Hydrogeology

Local hydrogeology varies according to local topography and season (wet or dry). Water is expected to flow

away from the ridgeline on site which extends from the PDR approximately 3km into the Base at the eastern

side and approximately 1.5 km into the Base from the western side (QLD Globe, 2017).

Localised groundwater flow is also expected to be influenced by the natural springs on the Base, depending

on proximity to these springs and flow in the springs.

Feasibility studies undertaken by GHD (1998) identified that ‘the vertical recharge and local discharge from

the aquifer at the Base will ensure that use of the water for airfield purposes will not affect Weipa's supply’.

GHD (1998) identified that groundwater flow direction within the upper aquifer was considered to be towards

the west, with a calculated groundwater flow rate (permeability or k value) for the shallow aquifer estimated

at approximately 30 m/day, confirmed by Maunsell in 2005.

The local hydrogeology is broadly defined by the unconfined sands of the Bulimba Formation. In parts the

sands are replaced with sandy clays, which will retard the recharge in those locations.

4.5.2.1 Beneficial Uses of Groundwater

In Queensland, water quality guidelines are developed under the frameworks outlined in the Australian and

New Zealand Fresh and Marine Water Quality Guidelines (ANZECC and ARMCANZ 2000) which have been

prepared as part of Australia’s National Water Quality Management Strategy (NWQMS).



Environmental values (‘EVs’) recognised in the national guidelines include:

aquatic ecosystems

primary industries, (including irrigation, stock watering, aquaculture, human consumers of aquatic

foods, general farm use)

recreational use (swimming, boating, visual recreation)

drinking water supply

industrial water

cultural and spiritual values.

4.5.2.2 On-site Groundwater Use

Given the property is Commonwealth land, a search for registered uses of groundwater in the Queensland

State databases does not necessarily provide a good indication of the presence of groundwater users.

Based on the site inspection and interview of Defence personnel, it was confirmed that groundwater is

extracted for use on the property for domestic, irrigation and other site operational purposes. Since late

2016, domestic purposes has not included drinking water supply as the Defence personnel currently use

bottled water for drinking.

A search of DNRM records in June 2017 identified seven registered groundwater bores on the Base. A summary of the information available from the DNRM bore search for these registered bore is provided in Table 4. The location of these registered bores is indicated on the map included with the bore search in Appendix E. Table 4: Registered Groundwater Bores onsite (DNRM, June 2017)

RN109173 1999 30 6.3 Not given

Titled “Peppin” on DNRM bore record. Identified in the SAQP bore search as located at the (intermittently occupied) Peppin residential camp area, 200m off-site. The current search places the bore with the Base land parcel.



The inferred use of these 7 bores is as follows:

Two of the bores identified during the bore search were reported by GHD (2001) to be BH04 (RN78994)

and BH34 (RN78995), understood to be observation bores installed to monitor the performance of the

sewage treatment plant (up and down-gradient of the STP).

Two bores installed in 1993 are located near the Accommodation Camp and titled “Bore 1” (RN78862)

and “Bore 2” (RN78863). Defence personnel interviewed during the site inspection indicated these

bores may have been installed for potential water supply purposes, however there was no knowledge of

their use and operation.

Two further wells are registered as installed on-Base in 1970, noted as Comalco No22” on the DNRM

bore construction record (RN92284, near western boundary) and “Comalco No23” on the DNRM bore

construction record (RN92285, east of the Accommodation Camp). Purpose of these bores is not

known. Given their installation by the former mining operator (Comalco), it is inferred they were installed

for exploration reasons.

The registered location for registered bore RN109173 is located at the southern western boundary of

the Base. The position of this bore matches the inferred location of the Peppin indigenous camp which

is intermittently occupied. The DNRM record confirms it is registered to “Peppin” and was installed in

1999. The bore construction record indicates the depth of the bore is 30 m with two slotted casing

intervals (4 to 8m and then 24 to 30m). The standing water level recorded on the bore construction card

was 6.3 metres below ground level. This bore was identified in the SAQP bore search as located at the

(intermittently occupied) Peppin residential camp area, 200m off-site. The current search of the NRM

records indicated that the registered location is within the Base land parcel.

A review of previous environmental site assessment reports indicates the presence of 14 groundwater

observation bores (monitoring wells) prior to the current investigation. A summary of the pre-existing

monitoring wells is provided in Table 6.

The groundwater monitoring bore network has been installed throughout a series of investigations

undertaken at the property to assess contamination. The distribution of monitoring wells reflect the objectives

of prior investigations that have been undertaken to assess the conventional contamination sources

(petroleum storage) and therefore have not specifically targeted AFFF activity. However there is some

degree of overlap with the known conventional contamination and AFFF sources.



Groundwater monitoring well depths were from 4.9 metres below top of casing (mbTOC) to 14.2 mbTOC,

and targeted the water bearing sands of the Bulimba Formation.

4.5.2.3 Off-site Groundwater Use

A review of registered groundwater bores registered with DNRM in QLD in the vicinity of the property was

undertaken to provide additional information on groundwater use. A search of the DNRM Groundwater

Database in June 2017 indicated approximately 22 registered groundwater bores located within 2 km of the

Base. The results of the Groundwater Bore Search are displayed in Appendix E. Details are provided in

Table 6.

Offsite: located south of the Peninsula Developmental Road.

The use of the water was not generally reported in the DNRM database records. Given the nature of the

surrounding land-use, a site reconnaissance was not possible to infer information on off-site groundwater

use and therefore the use of the offsite bores could not be confirmed without offsite community engagement.

The inferred use of these bores is as follows:

A number of bores are located west of the Base within the mining areas operated by Rio Tinto.

Although the location was registered with DNRM, detailed records for the construction or use of these

wells was not available in the DNRM registered bore database.

A number of bores are located south-east of Scherger (15 bores), south of the Peninsula Development

Road. The registered owner of all of these bores is not noted on the bore construction cards with the

exception of one bore (RN92286) registered to Comalco (now Rio Tinto) and drilled in 1970. The other

14 bores were drilled in 2014 and bore construction details recorded. The use of these bores could not

be confirmed from the records and interview information available.

Off-site use of groundwater for drinking water cannot be discounted given the lack of reticulated water supply

in the region. For example at the Peppin camp and possibly at the mining operations. Other use of

groundwater off-site is expected to include industrial water supply (for the mining operations) and

environmental monitoring at the mine site to the west.

4.6 Ecology

Custom environmental reports were produced for the site using the online report generator on the QLD

DEHP website. The reports requested comprised:



Matters of state environmental significance (MSES)

Regional ecosystems

Terrestrial biodiversity and aquatic conservation values

Copies of the reports are presented in Appendix D. These reports provide information on statutory and non-

statutory environmental interests and have been used to identify potential sensitive environmental receptors.

The vegetation at RAAF Base Scherger is predominantly eucalyptus woodland and open forest of the Cape

York Bioregion and Weipa Plateau Sub region, Embley catchment.

MSES: Vegetation Management Wetlands and watercourse are mapped as present

Biodiversity and conservation values reported by EHP include:

Aquatic conservation assessment (non-riverine) is low in the centre of the Base which relates to the

isolated lacustrine waterbodies identified.

Aquatic conservation assessment (riverine) ranges from ‘very high’ in the north east and south of the

Base, to ‘high’ in the south east and ‘low’ in the north west.

Spring-fed riverine wetlands are identified as a special feature and contain plant species of

conservation significance, regional ecosystems of conservation significance and have ecological

function including refugial areas, critical habitat for plants and key resources for birds, frogs and

reptiles.

Regional ecosystems indicated to be present on the EHP mapping comprise:

Biodiversity status of remnant regional ecosystems are of no concern at present

Isolated palustrine wetlands (swamps / lakes) and lacustrine and riverine waterbodies are present in

parts of the Base

High numbers of endemic plant species are reported. The vulnerable species Gardenia psidioides, and

near threatened species Acacia fleckeri, Archidendron hirsutum, Chrysophyllum roxburghii, Croton

brachypus and Litsea macrophylla occur in this ecosystem.

Important wildlife corridor for closed forest species.

Woodlands and open woodlands dominated by ironbarks such Eucalyptus cullenii (Cullen's ironbark),

E. staigeriana (lemon-scented ironbark) or E. melanophloia (silver-leaved ironbark) and bloodwoods

such as Corymbia stockeri subsp. peninsularis, C. clarksoniana (grey bloodwood) or C. leichhardtii

(rustyjacket).

The near threatened species Acacia ommatosperma occurs in this ecosystem.

A comprehensive ecological baseline survey was undertaken at the Base by GHD and summarised within

the Environmental Management Plan prepared for the Base (GHD, 1998). The EMP reported several

variants of Darwin Stringybark (E. tetradonta) and Melville Island Bloodwood (E. nesophila) have been

described in the area. This is the most extensive form of vegetation in the Weipa district and is widely

represented on Cape York regional mapping (QLD Globe, 2017). There are no endangered flora species

recorded on the site although two species, pitcher plant (Nepenthese mirabilis) and a fern (Lindsaea walkeri)

are described as rare. They are located near to the permanent springs and their outflows.

GHD identified a total of eighteen native and three introduced (feral cats, feral pigs and cattle) animal

species that are expected to inhabit the Base. The EMP identified that streams running from the springs are

sources of drinking water for these animals, as well as for a number of birds and frogs. The only species of

freshwater fish recorded in the streams draining the Base is the rainbow fish (Pseudomugi gertrudae) which

GHD found is described as rare by the Australian Society for Fish Biology. However, GHD considered this



may be due to the limited applicability in the far north of Australia because of the lack of information on the

region. (GHD, 1998).

Invasive weed Croton Hirtus is known to be present in parts of the Base.

5.0 REVIEW OF PREVIOUS INVESTIGATIONS

focused on reports and information that included reference to AFFF use, storage and waste disposal,

historical monitoring data or environmental conditions (geology/hydrogeology etc.) at the property. This is not

a summary of all previous reports, but of only information relevant to this PFAS PSI.

A summary of pertinent documents is provided below:

1989 –Report on Groundwater Investigation, Cape York Airfield Environmental Assessment Phase

(reference 0901g, Report WS1 March 1989, GHD)

This is the earliest report available to Golder as part of this PSI on the baseline groundwater investigations at

Scherger. An exploratory hydrogeological assessment was undertaken at the proposed airfield site as part

of the initial impact assessment studies. A network of observation bores were drilled to understand seasonal

water variations, the aquifer recharge capability and the potential water supply was assessed through

installation of a production bore.

1998 –Environmental Management Plan, RAAF Base Scherger (1998, GHD)

The EMP was prepared for the operation of the Base, to provide requirements for the environmental

management of the Base and its surrounds. It contains a set of procedures for the environmental



management of the Base, together with specific monitoring requirements and mitigation measures aimed at

minimising adverse impacts.

2001 – Environmental Works, North Queensland, Technical Report on RAAF Scherger Environmental

Monitoring (reference 42\10211\00- 46073, September 2001, GHD)

By 2001, monitoring wells BH34 (near the sewage treatment plant) and BH4 (south of the Motor Transport

Facility) had been installed and were subject to periodic monitoring. The report stated that the 2 wells were

intended for the assessment of groundwater impacts from the sewage treatment plant with BH4 upstream

and BH34 downstream.

The report also references earlier investigations by GHD between 1989 and 1992 to identify a viable

groundwater source for RAAF Scherger. It was reported that the identified aquifer at Scherger is the same

shallow aquifer (lying immediately below the bauxite) that the township and the mining operations extract

water supplies from. Water levels were reported to fluctuate over at least 2m on average between the wet

and dry seasons in the timeframe 1992 to 2001.

2005 – NQ01150 – Groundwater Monitoring Well Installation, Sample Capture and Monitoring Report,

RAAF Base Scherger AVTUR Fuel Farm (2004/2005) (reference 80200705, August 2005,

Maunsell/AECOM)

A summary of the regional geology and hydrogeology reported by Maunsell is included below:

Site geology encountered during the advancement of the groundwater monitoring wells consisted of

bauxite/ferricrete with an approximate thickness of between 5 – 6m, underlain by a shallow sand

aquifer, which reaches depths of 11 – 12m below ground level (bgl). The sand aquifer was underlain by

kaolinite clay overlaying mudstone. Maunsell installed monitoring wells RAAFSGR10 to RAAFSGR13

inclusive surrounding the Aviation Fuel Farm in 2005;

The principal aquifer used for water supply within the Base, is an unconfined sandy horizon

approximately 3 – 14m thick;

Groundwater flow direction within the upper aquifer was reported by Maunsell to be towards the west;

The calculated groundwater flow rate (permeability or k value) for the upper sand aquifer is

approximately 30 m/day

2009 - RAAF Base Scherger Environmental Monitoring Program for Water Quality (NQ1998) – Draft,

May 2009 (ENSR – AECOM)

A draft version of the RAAF Base Scherger Environmental Monitoring Program for water quality dated 2009

has been reviewed. This Environmental Monitoring Program is specific to water quality monitoring, and

builds on the outcomes of past programs and outlines the process for environmental performance monitoring

– schedule, procedures and water quality objectives. This version is superseded by the AECOM 2010 EMP

described below.

2010 - RAAF Base Scherger Environmental Monitoring Program for Water Quality (NQ1998) – Draft,

May 2009 (AECOM)

A revision of the Environmental Monitoring Program dated 2010 (AECOM) has been prepared for the Base.

While not stored on the CSR directly, it was attached to the Jacobs 2016 monitoring report as Appendix F.

This revision of the Environmental Monitoring Program sets out a sampling plan of surface waters and

groundwaters for the purpose of environmental compliance.

Surface water sample locations noted in the Program were as follows:



RAAFSCHSW1: reference site described as In spring fed creek above junction with branch on which

RAAFSCHSW2 is located, but below springs (spring and surrounds are culturally significant and should

be avoided)

RAAFSCHSW2 (monitoring potential impacts from fuel farm): On spring fed creek closest to the fuel farm,

2013 – Environmental Investigation of USTs/ASTs Across the Defence Estate, Stage 1 & 2 Report –

RAAF Base Scherger (May 2013, Golder)

Golder completed a Stage 1 & 2 Environmental Investigation to assess potential ground contamination

associated with fuel storage across the base. The Stage 2 investigation scope included drilling of additional

groundwater wells onsite and sampling of monitoring wells specific to fuel storage areas.

Golder installed an additional six wells (RAAFSGR14-RAAFSGR19) as part of the UST/AST investigation.

Primarily these were installed around fuel storage/distribution areas.

2016 – PFAS Environmental Management Program: Category 2 Property Data Gap Assessment –

RAAF Base Scherger (September 2016, Golder)

Golder (2016) completed a Data Gap Assessment which included a desktop review and site interviews to

address information uncertainties to categorise and prioritise the investigation of the property within

Defence’s PFAS Environmental Management Program. No intrusive investigation was undertaken.

The report identified limited AFFF use (refer Section 6.2 for details). It was identified as part of the June

2016 site visit that the Base extracted groundwater for water supply requirements (including drinking water

supply). It was also indicated in June 2016 that the nearby indigenous community (Peppin) may be using

extracted groundwater for domestic water supply. Updates on this information have been received in early

March 2017 by Defence and summarised in Section 4.5.2.3. Conclusions from this Data Gap Assessment

resulted in the completion of this PSI.

2016 – RAAF Base Scherger Groundwater Monitoring Reports Post Dry Season (Round 1) and Post

Wet Season (Round 2) (September 2016, Jacobs)

The groundwater monitoring program scope was related to monitoring of fuelling operations between 2015

and 2016. Jacobs noted in their results a report from GHD in 2002 (‘Report on RAAF Base Scherger

Groundwater Monitoring’) that indicated the presence of MBAS in results from 1996 and 1997.

Methylene Blue Active Substances (MBAS) is an indicator of anionic surfactants such as detergents and as

an indicator of PFAS before specific analytical methods were available to market. Jacobs noted that anionic

surfactants were reported in the 2002 GHD report at 0.02 mg/L (20 µg/L) at RAAFSCH_GW04 (also

identified as BH04, GHD 2001) and RAAFSCH_34 (also identified as BH34, GHD2001) in their historic

results data table. Anionic substances detected by MBAS assays include sulfonates, phosphates, sulfates

and carboxylates, and given the broad nature of this test may detect naturally occurring compounds.

This assessment compared water quality concentrations to the ANZECC freshwater trigger values (95%

protection) following the framework outlined in the RAAF Scherger Environmental Management Plan (EMP)

(AECOM, 2010).

2016 – RAAF Scherger Surface Water Monitoring Report (September 2016, Jacobs)

Jacobs completed periodic surface water monitoring of three sampling sites on RAAF Scherger including

one reference site and two monitoring sites. RAAFSCHSW1 was collected close to the location of Spring

no. 1 (refer Figure 2). RAAFSCHSW2 was collected downstream of the confluence of streams arising from



Spring 1 and Spring 2 (Refer Figure 2 for the location of Springs). RAAFSCHSW3 was collected

downstream of RAAFSCHSW2, northwest of the sewage treatment plant. Background information on the

hydrogeological and hydrological interactions between surface and groundwater was not documented in this

report.

This assessment compared water quality concentrations to the ANZECC freshwater trigger values (95%

protection) following the framework outlined in the RAAF Scherger EMP (AECOM, 2010).

6.0 PFAS SOURCE IDENTIFICATION

Presented below is a summary of the collective understanding of AFFF storage, use and waste disposal for

the property established during this PSI and the Data Gap Assessment (Golder, 2016). A summary for each

source area is presented in Appendix A.

The current Scherger Defence personnel supplemented information gathered during the 2016 Data Gap

Assessment. Given that there have been limited activations of the Base (Exercise Kakadu is the only full

Base activation in 2005), AFFF has not been used in routine training (either fire-fighting training or

equipment training) activities. AFFF has been stored in preparedness for military activation of the Base.

6.1 AFFF Storage

Identified AFFF storage included the following:

The main AFFF product historically used at the property was 3M Lightwater which contained PFOS,

PFOA and 6:2 FTS. The 3M Lightwater product was since replaced by Ansulite.

AFFF was stored in mobile equipment including fire trucks utilised during the 2005 exercise. It is

understood that a fire truck with foam capability was stored at RAAF Scherger prior to and after the

2005 exercise in Building 707.

At the time of Base commissioning, it was intended that there would be 1 x 50 litre foam fire

extinguisher at each of the following locations, totalling 15 extinguishers: OLAs (10), Marine Hangers

(2) and the General Purpose Apron (3). Subsequent to the Base being commissioned, extinguishers

were later stored in centralised locations at OLA 3 and OLA 8 for all 15 x 50 L mobile extinguishers. The

time frame for when fire extinguishers became centrally located could not be ascertained.

6.2 AFFF Use

AFFF was used in a training exercise for emergency fire response or discharged to ground during

extinguisher maintenance. Further details of AFFF use at Scherger Base has been summarised in Table 8.

Table 8: Potential AFFF use

AFFF Use Area Frequency Use Description

2005 Exercise Training Areas (unknown locations)

Fire trucks parked at Building 7 fire station during the exercise.

one-off for 2005 Exercise

Building 7 is the nominated fire station for RAAF Base

Scherger. During the 2005 Kakadu Exercise, fire trucks were

stationed here. During the course of this investigation,

Defence were not able to identify personnel who had first-

hand knowledge of the extent of training that was undertaken

during the 2005 Kakadu Exercise.

Defence personnel indicated as part of air movements that

would have occurred during the Exercise, that testing of the

fire equipment would have included the generation of foam.

However, the location where the fire equipment was tested

could not be confirmed by Defence personnel interviewed.

Noting that no firsthand knowledge was available, Defence

RAAF personnel suggested that foam training may have been

undertaken at a range of locations including the roadways




immediately adjacent to the Fire Station and the helipad

opposite, the taxiway, the OLAs, GPA and runway based on

their aviation exercise experience.

Building 7 is located approximately 150 m from the taxiway.

Immediately opposite and east of Building 7 is a large open

piece of cleared land comprising two helipads with an access

road to the helipads.

In the absence of firm knowledge of the exact locations for

fire training, it would seem plausible, to the current Defence

personnel, that fire training may have occurred in this locality

given the nearby presence of the fire station and that foam

training near the taxiway may have been restricted due to

aircraft movements during the Exercise. Additionally, the

taxiway is over 3km long and any fire training on the taxiway

may have occurred at discrete unidentified locations along its

length making the targeted selection of investigation locations

not possible.

OLAs and Marine Hangers

Annually between 1998 and 2014

Extinguishers were positioned at OLAs and Marine Hangers

for Base preparedness in case of fire emergency. Fire

extinguishers were serviced annually and involved purging of

the waste AFFF onto the ground at each storage location until

approximately 2014.

It was reported that early in the Base’s operation, that the

storage location of extinguishers was relocated to both OLA3

and OLA8 for ease of access when servicing.

The exact location of the extinguisher servicing and disposal

of waste AFFF at the OLA3 and OLA8 was not known.

Surface drainage from the OLA areas flows via formed

drainage channels ultimately to the retention basin (see

discussion below).

The site personnel were not aware of fire incidents or fire

training using the extinguishers.

General Purpose Apron

Annually until 2014

At the GPA it is understood that maintenance of fire

extinguishers containing AFFF involved discharging the

contents of the extinguisher to ground. This practice is

understood to have occurred until circa 2014. Site personnel

observed this occurring on the northern side of the Air

Movements Hanger (asset reference 001). Site

observations and review of site drawings confirmed that the

drainage in this locality flows both locally to the south-east

(from the eastern side of the facility) and secondly, a major

component of the flow discharges to the south-western side

of the GPA towards an oil-water interceptor. The component

of the drainage associated with observations of AFFF

disposal is locally towards the south-east. Subsequently, the

drainage from both of these areas ultimately drains to the

retention basin (see discussion below).




The site personnel were not aware of fire incidents or fire training using the extinguishers.

Building 707 Warehouse

Annually from 2014

Since 2014, Lewie Fire has used this warehouse for the servicing of their contracted fire extinguishers. Fire extinguishers are serviced annually and involve purging of the waste AFFF into IBC. Alternately, waste extinguishers are removed offsite and replaced with new extinguishers. Previously foam fire truck parked in this warehouse.

Motor Transport Facility (Vehicle Refuelling) - Building 701; and

Aviation Fuel Farm; and

Fuel Tanker Refuelling Bay

Annually Extinguishers positioned at each of these facilities for Base preparedness in case of fire emergency. Serviced centrally in Warehouse 707 or alternately old extinguishers replaced with new.

The Aviation Fuel Farm is topographically downgradient of the OLAs


Once off observation of AFFF waste disposal

Information received during the 2017 site inspection from a

Lewie Fire Contractor included a report of possible historical

discharge of waste AFFF to ground in this vicinity. The

observation made was a once off rather than knowledge of an

ongoing routine waste disposal practise. It’s understood that

the possible waste disposal occurred on the northern end of

the motor transport facility compound.

6.3 AFFF Disposal

Based on the interviews conducted with Defence personnel, there were no known major spills or leaks of

AFFF concentrate at the property.

From approximately 2014, waste disposal practises of AFFF during extinguisher maintenance was changed.

Waste AFFF was temporarily stored onsite in IBC. IBC consequently transported offsite for appropriate

disposal by Chubb.

Alternately, waste extinguishers are removed offsite and replaced with new extinguishers.

6.4 Offsite Sources

Mining operations occur to the immediate west of RAAF Scherger. The extent of fire protection equipment

(or its disposal) or if any fire response training is conducted at the mine could not be established as part of

this scope.

6.5 Summary of PFAS Sources

Based on the information reviewed and reported by Defence, the most likely sources of the PFAS are related

to Defence related activities that occurred within the boundaries of the property.

These included:

Ordnance Loading Areas, in particular OLA 3

and OLA8.


Fire Station Building 7




The timing, exact location and, mass of PFAS that historically discharged at source areas were not recorded

and therefore are not known. A summary of the information available from Defence personnel has been

documented above and in Appendix A.

The Aviation Fuel Farm and the Central Power Station were also identified as hosting extinguishers,

however, no training or servicing of that equipment was reported by Defence personnel to have occurred at

those locations. These facilities are down-gradient of the airfield, OLAs and Fire Station and therefore may

be migration pathways for potential contamination.

7.0 DATA QUALITY OBJECTIVES

As per Schedule B2 (Guideline on Site Characterisation) of the NEPM “a systematic planning process is

used for defining the objectives of a site assessment and to develop a sampling plan for the collection and

evaluation of representative data to achieve those objectives. Without systematic planning, the site

assessment may be ambiguous or inconclusive, which may lead to additional sampling requirements,

resulting in increased costs and project delays”.

In its simplest form, the planning process outlined in the NEPM should consider:

the overall objective of the site assessment,

the decision(s) to be made on the basis of the site assessment findings,

the constraints on the assessment (financial, time and logistical), and

the degree of flexibility to conduct follow-up investigations.

This project level information can then be used to identify the specific site information needed to address the

assessment objectives.

The Data Quality Objectives (DQOs) process is used to define the type, quantity and quality of data needed

to support decisions relating to the environmental condition of a site. The seven step DQO/data quality

indicator (DQI) process is identified in Schedule B2 of the NEPM as one example of a suitable systematic

planning approach for site investigations.

The DQO process involves the seven steps as follows:

Step 1: State the problem

Step 2: Identify the decision or goal of the investigation

Step 3: Identify the information inputs

Step 4: Define the site boundaries

Step 5: Develop the analytical approach

Step 6: Specify performance or acceptance limits

Step 7: Develop the plan for obtaining data.

The DQO process has been applied as described below, to ensure that data collection activities are

appropriate and achieve the stated objectives.

7.1 Step 1: State the problem

The original driver for the PSI was to address the identified data gaps associated with uncertainty on the

categorisation of RAAF Base Scherger.

Identified data gaps at RAAF Base Scherger prior to the PSI included:

Existence and use of bores in the vicinity of the property.



Presence of PFAS in soil, groundwater, sediment and surface water on the site, at nominated potential

source areas and possible migration pathways.

Location and volume of AFFF foam training.

7.2 Step 2: Identification of the decision or goal of the investigation

The PSI was completed in accordance with the NEPM requirements for a Preliminary Site Investigation. The

assessment targeted specific data gaps for the property and the collection of environmental samples to

support the project objective.

The PSI was limited to use, storage and waste disposal associated with AFFF products and associated

potential PFAS contamination at the property.

7.3 Step 3: Identify the information inputs

For the PSI the major inputs were:

Existing reports and information relating to use, storage and waste disposal of AFFF, environmental

conditions (geology/hydrogeology etc.).

Existing investigations reports to confirm the environmental setting of the site including the presence of

available monitoring well locations, either located in the immediate vicinity of potential source areas or

at down-gradient of potential source areas.

Publically available historical information for the Property including:

Historic aerial photographs.

Topographical, soil and geological maps.

Site inspection and interview with Defence identified employees regarding the use, storage and

disposal of AFFF.

Collection of representative soil, sediment, surface water and groundwater samples, and laboratory

analysis of the samples at source locations.

7.4 Step 4: Define the investigation boundaries

The lateral boundaries of the investigation area are shown in Figure 1. The property has an area of

approximately 5,500 hectares.

The vertical boundaries of the investigation area were:

Soil - generally to a depth of 20 m.

Groundwater - the groundwater aquifer immediately underlying the site is at depth of approximately

10m, however it is expected to be seasonally variable.

Surface water – if present during the field investigation.

Sediments - in drainage lines to a depth of 0.15 m.

7.5 Step 5: Develop the analytical approach

The purpose of this step was to define the parameters of interest, specify action levels and combine the

outputs of the previous DQO steps to develop a series of options if certain trigger events occur.

A decision on the acceptance of the analytical data will be made on the basis of the DQI (Section 10.2).

The results of soil, sediment, surface water and groundwater analytical data were compared with the

adopted site criteria (Section 10.2) to assess the presence of PFAS at the property to support the re-

categorisation process.



Contaminant concentrations in excess of the guidelines provided in Section 9.0 will be taken into

consideration in the re-categorisation process and may indicate the need for further investigation of human

health and environmental risk.

7.6 Step 6: Specify performance or acceptance limits

DQIs were developed based on the following PARCC parameters including:

P - Precision: A quantitative measure of the variability (or reproducibility) of data;

A - Accuracy: A quantitative measure of the closeness of reported data to the “true” value;

R - Representativeness: The confidence (expressed qualitatively) that data are representative of each

media present on site;

C - Completeness: A measure of the amount of useable data from a data collection activity, and

whether it is all the data required to enable the objectives to be met; and

C - Comparability: The confidence (expressed qualitatively) that data may be considered to be

equivalent for each sampling and analytical event.

The measures/criteria employed to enable review of these parameters are as follows and are detailed in

SAQP (Golder 2017).

Precision

Field precision was monitored through the use of Golder’s standard operating procedures and ensuring that

these were complied with throughout the sampling event(s). Suitable performance indicators for assessment

of laboratory precision include performance of intra-laboratory and inter-laboratory duplicate sample sets

through calculation of Relative Percentage Differences (RPD).

Accuracy (Bias)

Accuracy in the field activities was monitored through the use of SOPs and ensuring that these were

complied with throughout the sampling event(s). Furthermore, since PFAS are found in numerous items the

following special precautions will be taken during all sampling activities:

No use of TeflonTM containing materials (i.e. TeflonTM tubing, bailers, tape, plumbing paste);

No TyvekTM clothing were worn;

No clothing with stain or water resistant treatments (such as GoreTexTM) were worn;

No Post-ItTM Notes;

No fast food wrappers, aluminium foil, disposable cups or microwave popcorn were to be handled or

brought on site;

Hands were to be washed prior to any sampling activities after handling such items listed above, and

Nitrile gloves are to be worn during all sampling and sample handling activities; and

Chemical (blue) ice packs were not to be used.

PFAS can bind to glass, therefore all samples were collected into laboratory supplied high density

polyethylene (HDPE) or polypropylene containers.

The closeness of the reported data to the “true” value is assessed through review of performance of:

Method blanks, which are analysed for the analytes targeted in the primary samples;

Matrix spike sample sets;

Surrogate spikes; and

Laboratory control samples.



Representativeness

To ensure the data produced by the laboratory is representative of conditions encountered in the field, the

following steps were taken:

Blank samples were run at the laboratory in parallel with field samples to confirm there are no unacceptable instances of laboratory artefacts;

Review of RPD values for field and laboratory duplicates to provide an indication that the samples were generally homogeneous, with no unacceptable instances of significant sample matrix heterogeneities; and

The appropriateness of collection methodologies, handling, storage and preservation techniques were assessed to ensure/confirm there was minimal opportunity for sample interference or degradation (i.e. volatile loss during transport due to incorrect preservation/transport methods/sampling technique for example).

Completeness

In assessing the completeness of the field data the following is considered:

All critical locations and depths sampled;

Representative samples collected; and

An appropriately experienced sampling team is engaged in the investigation program.

In validating the degree of completeness of the analytical data sets acquired during the program the

following was considered:

Whether SOPs for sampling protocols have been adhered to; and

Copies of all project chain of custody (COC) documentation are reviewed and presented.

Comparability

No prior investigations had assessed for the presence of PFAS in the sampling media analysed.

During the PSI, data was collected by experienced samplers and National Association of Testing Authorities,

Australia (NATA) accredited laboratory methodologies were employed in all laboratories.

7.7 Step 7: Develop the plan for obtaining data

Sample locations were selected based on the observed site conditions and on the site history established

from interviews with Defence personnel. The investigations may identify further areas requiring assessment

and thus the overall approach would be modified as required following refinement of the preliminary CSM

presented in SAQP (Golder 2017). The broader sampling strategy is presented in Table 9 and proposed

locations are shown in Figure 3-1 to Figure 3-16. A key map showing the extent of figures prepared across

the property is provided as Figure 3A. Changes to the sampling and analytical plan are discussed in

Section 8.0.

8.0 SAMPLING, ANALYSIS AND QUALITY PLAN

A Sampling, Analysis and Quality Plan (SAQP) was prepared for this investigation as documented in the

report titled RAAF Base Scherger (1218) Sampling, Analysis and Quality Plan, dated 13 April 2017.

The SAQP includes comprehensive description of the sampling methods and field procedures adopted for

the site investigation.

The SAQP was implemented as proposed with the following deviations noted:

Locations SW001 to SW005 inclusive, as well as SW008 and SW010 did not have surface water at the

time of sampling. Therefore no water sample was obtained. However, sediment samples were however

still collected from these locations.

Additional surface water and sediment sampling locations (SD/SW011 to SD/SW013) were added to

the program following the issue of the SAQP in response to several proposed locations being relocated,

inaccessible or dry. The rationale for including these new locations is described below:

Collection of 1 surface water and 1 sediment sample (SW011 and SD011) at the western portion of

Base within drainage flow pathway downstream of the operational areas on base ( (Figure 3-15)

Collection of 1 surface water and 1 sediment sample (SW012 and SD012) at the creek near

western boundary downstream of the operational areas on base (Figure 3-14)

Collection of 1 surface water and 1 sediment sample (SW013 and SD013) from an un-named creek

north of the runway near the source of Spring no. 4. (Figure 3-16).

Locations SD/SW006, SD/SW007, SD/SW008 and SD/SW009 were moved from their original planned

locations due to access limitations onsite, as described in Table 11.

A groundwater sample was intended for collection from Sewage Treatment Plant (RAAFSGR34 or

BH34) however the bore could not be located due to the presence of dense scrub and suspected

Croton Hirtus weed.

These deviations from the SAQP are not considered to affect the outcome of the assessment and the

objectives of the PSI can still be met.

9.0 ASSESSMENT CRITERIA

Given the preliminary nature of the investigation and the preliminary identification of receptors, the analytical

results are screened against an adopted set of guideline values as part of a Tier 1 screening level

assessment which includes both health based and ecological based criteria

The Defence project guidelines (Defence Contamination Directive #8 (DCD8), Amendment 1 and 2, DoD

Sept 2016 and May 2017) for poly and per-fluoroalkyl substances have been adopted for this PSI.

Complementing DCD8, supplementary criteria have been selected to support the assessment for ecological

protection exposure pathways not referenced in DCD8 from the following Guideline:

Draft Commonwealth Environmental Management Guidance on PFOA and PFOS (Department of the

Environment and Energy, 2016) for the protection of ecological values.

Consistent with the RAAF Scherger EMP framework and the water quality field measurements, the 99% level

of species protection for freshwater ecosystems has been selected as the adopted criteria. Due to limits of

laboratory detection methods, the laboratory detection limit will be used as a practical standard.

Aside from the stage of the investigation being preliminary, it was considered appropriate to nominate both

human health (given the water supply) and ecological (aquatic waterway spring) receptors have been

identified onsite.

a groundwater monitoring well (MW022, MW023, MW024, MW025, MW026 and MW027).

Fill material was encountered at BH022 (GPA) and BH024 (OLA3) to a depth of 0.4 m and 0.9 m only, and

comprised primarily of clayey gravelly sand.

Lithology encountered at BH027 was primarily silty clays. BH027 is located on the north western extent of

the Base, at a lower elevation than other areas investigated. Soils encountered at all other bores varied

intermittently between clayey sand, clayey gravelly sand and silty sand, varying to sandy clays in some parts

of the Base. White sand and kaolin clay clasts are present at depth. The shallow horizon, described as

sandy clayey gravel, silty clay or silty sand was found up to approximately 1.2 m depth.

10.1.2 Groundwater

Groundwater was assessed in the following areas:

Aviation Fuel Farm (RAAFSGR10)

Central Power Station (RAAFSGR14)

Motor Transport Facility (RAAFSGR18, RAAFSGR19)

General Purpose Apron (MW022)

Building 7 (MW023)

Ordnance Loading Area 3 (MW024)

Ordnance Loading Area 8 (MW025)

South-Western locality of Base (MW026)

North-western portion of site near site boundary (MW027)

Bore water was sampled from the Water Treatment Plant (WTP) pre-treatment (W001) and post-

treatment (W002).

Gauging data and field water quality results are provided in Tables A and B (attached).

New monitoring wells and monitoring wells sampled in this investigation were surveyed to establish their

height datum and location. The report provided by the surveyor is included as Appendix I.

Depth to groundwater ranged 5.1 metres below top of casing (mtoc) (RAAFSGR19) to 14.02 mbtoc (MW24).

Groundwater elevations ranged 39.1 m AHD (RAAFSGR18) to 15.7 m AHD (MW027). Based on the current

monitoring data, groundwater is inferred to flow in a west to northwest direction, towards Mission River.

GHD (1998) identified that groundwater flow direction within the upper aquifer was considered to be towards

the west, with a calculated groundwater flow rate (permeability or k value) for the shallow aquifer estimated

at approximately 30 m/day, confirmed by Maunsell in 2005.

Groundwater was typically fresh and slightly acidic, with conductivity (EC) values ranging from 17.50 S/cm

(RAAFSGR18) to 87.8 S/cm (RAAFSGR14) and pH values ranging 4.52 (MW024 – 5.64 (MW026). There

were no noticeable odours or sheens, and non-aqueous phase liquid were not encountered in the

observation wells sampled.

Water samples collected from the water treatment supply, pre- and post- treatment were fresh (22 S/cm -

27 S/cm) and slightly acidic (5.21 – 6.53 pH).

10.1.3 Surface water and Sediment

Sampling and analysis of six surface water and 13 sediments was undertaken from natural and formed

surface drainage features around the Base. The intention in the SAQP was for sediment and surface water



samples to be co-located. Where surface water was present, this occurred. In some locations, only sediment

samples could be collected. Sampled areas included:

Ordnance Loading Area 3 (SD001 sediment only, drainage channel dry) (Figure 3-3)

Ordnance Loading Area 8 (SD002 sediment only, drainage channel dry) (Figure 3-3)

General Purpose Apron (SD003 and SD010 sediment only, drainage channel dry) (Figure 3-5)

Fire Station Building 7 (SD004 sediment only, drainage channel dry) (Figure 3-6)

Retention Basin (SD005 sediment only, drainage channel dry) (Figure 3-4)

Creek – south west portion of Property, slightly down-stream from location of where Peppin community

occasionally camp (SW006 and SD006) (Figure 3-13)

Creek near road crossing which is part of drainage pathway from Building 7 locality and CPS locality

(SW007 and SD007) (Figure 3-7)

Western property boundary near Sewage Treatment Plant (SD008 sediment only, drainage channel

dry) (Figure 3-12)

Creek in north west portion of property near northern site boundary (SW009 and SD009) (Figure 3-1)

Western portion of property within drainage flow pathway downstream of the operational areas on base

(SW011 and SD011) (Figure 3-15)

Creek near western boundary downstream of the operational areas on base (SW012 and SD012)

(Figure 3-14)

Unnamed creek north of the runway near the source of Spring no. 4 (SW013 and SD013). (Figure 3-16)

Measurements of electrical conductivity from surface water samples indicated that the water is fresh, ranging

from 3 mg/L to 26 mg/L. pH was also reported at slightly acidic conditions from the surface water samples.

Sediments from the site water features consisted predominantly of silty sands with some organic matter.

Creek and drainage channels throughout the site are highly vegetated. The sediments in creek and drainage

channels were predominantly a combination of decaying organic matter and silty sands (generally brown in

colour).

Surface water quality parameters are provided in Table B (attached).

10.2 Data Validation

10.2.1 Data Quality Indicators for Field Program

The details of the data validation assessment are included in Appendix G.

Data quality indicators (DQIs) for the field work sampling and analysis were implemented to ensure data is

valid and complete for the site assessment and that the DQO (Section 7.0) have been met. DQIs included

the following:

The sampling program has obtained samples from the nominated media at the investigation locations

where possible to do so. Section 8.0 confirms the proposed samples that could not be collected;

The Laboratory Limit of Reporting (LOR) were below the adopted criteria where technically possible.

The adopted criteria for protection of ecological receptors for waters was lower than the available

laboratory LOR.

Sample preservation, storage, and holding time of samples were within acceptable limits;

Field and analytical laboratory sample Chain-of-Custody (CoC) procedures and documentation were

completed;



Analytical results for replicated samples, including field and laboratory duplicates and inter-laboratory

duplicates, expressed as Relative Percent Difference (RPD) were within the nominated acceptance

criteria for field duplicates and splits. Australian Standard AS4482.1-2005 (SA 2005) indicates that

acceptable results are indicated by a RPD of better than 30 to 50 %, but notes that the variation can be

expected to be higher for organic analytes than inorganic analytes, and higher where there are low

concentrations of analytes. Tiered acceptance criteria have been adopted for assessment of RPDs as

follows:

Results < 10 times LOR: any RPD are acceptable;

Results ≥ 10 times and < 20 times LOR : RPD < 50% and

Results ≥ 20 times LOR: RPD < 30%.

Rinsate blanks were collected at the frequencies outlined in SAQP to assess the potential for cross-

contamination during field sampling. PFOS was detected in rinsate water samples QC305 and QC309

(0.003 g/L respectively). This concentration is only marginally above the LOR of 0.002 g/L. QC305

was collected from auger wash water after drilling BH023 on 10/05/2017. QC309 was collected from

dip meter wash water after sampling new groundwater wells on 15/05/2017. The positive identification

in these samples may represent an overestimation or false positive of PFOS in primary samples. Given

the number of samples reported below the laboratory limits of reporting, this is not considered to be a

significant issue to question data quality; and

Laboratory spikes, controls and surrogates targeted were within 70% and 130%, demonstrating the

reliability of the laboratory results reported.

Precision and Accuracy (Bias)

Following completion of the field program, the information collected was checked, collated, and summarised

in tabular form. The results of the laboratory analyses have been assessed and validated progressively using

recognised QA procedures.

The primary objective of the data validation process has been to ensure that the data reported can be used

to achieve the project objectives.

The validity of the analytical data reported has been assessed by a critical review of the QC check sample

results. The validation process is based upon the following data validation guidance documents:

National Environment Protection (Assessment of Site Contamination) Measure 1999 (NEPC 2013);

USEPA Contract Laboratory Program National Functional Guidelines for Superfund Inorganic Data

Review (US EPA, 2010); and

USEPA Contract Laboratory Program National Functional Guidelines for Superfund Organic Methods

Data Review (US EPA, 2008).

Accuracy and precision measurements from the appropriate QC check samples have been compared with

the analytical DQOs to assess the quality of the analytical data. Data validation records are presented in

Appendix G.

Representativeness

The data produced by the laboratories was representative:

Method Blanks – Analytes were not detected above the Laboratory Limit of Reporting (LOR);

Field Duplicate RPDs (interlaboratory and intralaboratory) - Review of RPD values for field and

laboratory duplicates provided an indication that the samples are within the acceptable limits.



Fieldwork - decontamination procedures were undertaken at each location. Three rinses (1x tap water,

2x DI water) were used to clean instruments and tools. For soil work, scrubbing with wire brush (metal)

then rinsing was completed; and

Samples - were handled, stored and transported in accordance with the requirements NEPC (1999).

Samples were transported under full chain of custody documentation. The laboratory returned a copy of

the signed COC acknowledging the receipt data and time and identity of samples included in the

shipment.

Completeness and Comparability

In order to assess comparability, field sampling procedures, laboratory sample preparation procedures,

analytical procedures and reporting limits were similar to established protocols.

10.2.2 Data Validation Conclusion

The QA/QC program and quality of the analytical data is considered to be sufficient for environmental

interpretation and to allow the objectives of the investigation to be assessed.

10.3 Laboratory Analysis

Soil, groundwater, surface water and sediment samples were submitted to the nominated laboratories for

10.3.4 Investigation Derived Waste

Surplus soil from the drilling and installation of groundwater monitoring wells was transferred to an on-site

quarry pit designated for temporary stockpile of soils. The dedicated stockpile was placed on a plastic liner

and covered. Samples of the investigation derived waste were analysed for characterisation (refer photo in

Appendix B). A volume of investigation derived soil waste in order of 6 m3 was generated and three primary

samples collected. Low concentrations of PFOS were detected in the samples at concentrations close to the

LOR (reported concentration of 0.002 mg/kg to 0.0024 mg/kg).

11.0 CONCEPTUAL SITE MODEL

The revised PFAS conceptual site model (CSM) is based on the initial CSM presented in the SAQP (Golder

2017) and was revised with the results of the PSI. The sampling and analysis undertaken as part of the PSI,

is based on the CSM which was prepared using the information predominantly gained through Site

inspections and interviews undertaken as part of this PSI. The sample locations targeted the areas

considered most likely to host PFAS contamination, however, it not a comprehensive investigation.

The initial CSM aims to provide an understanding of the potential for exposure to the PFAS contamination.

A potential risk can only exist where confirmed sources and receptors are linked by a complete exposure

pathway. Based on the objectives of the PSI the CSM only considers PFAS.

A visual schematic of the conceptual site model is provided as Figure 7.

11.1 Sources

PFAS detections were reported in the following media:

Shallow soil (upper 1m) at the General Purpose Apron, Building 7 and OLA8;

In sediment samples collected in the operational parts of the property including the OLA3, OLA8, GPA,

Fire Station Building 7, Retention Basin and downgradient of the Central Power Station. Sediment

samples collected closer to the western and northern property boundaries did not report PFAS

detections.

In surface water at SW013 located north of the runway and near Spring no. 4. (All other surface water

samples collected along the downgradient western boundary creeks were reported below LOR.)

In all groundwater samples, excluding the monitoring well installed at Building 7 and at the monitoring

well in the south-west portion of the property. Concentrations of PFHxS/PFOS were relatively higher at



OLA8, Aviation Fuel Farm, the Central Power Station and the Motor Transport Facility compared to

other locations monitored on-property.

PFAS was not detected in the 2 water supply samples collected at the water treatment plant.

A number of PFAS source areas were identified. As a general remark, Defence personnel indicated that the

extent of AFFF usage was reasonably limited at this bare Base in that the conduct of foam training was

limited to one event during the Exercise Kakadu in 2005. Other AFFF usage has been associated with the

servicing of fire extinguishers and associated waste disposal.

Identified PFAS sources were as follows:

OLAs, in particular OLA 3 and OLA8

The review of historical documents and interviews with current and former base personnel indicated that there has been routine servicing of fire extinguishers where waste AFFF was historically discharged to ground.

During the PSI, two groundwater samples were collected in the vicinity of the OLAs. PFAS detections in

groundwater found in this locality are at concentrations exceeding the criteria for protection of ecosystems

(and also exceeding the drinking water criteria at OLA8). Shallow soils and sediment results also indicated

detections of PFAS.


Routine servicing of fire extinguishers where waste AFFF was historically discharged to ground was also identified to occur at the GPA. Concentrations of PFAS compounds were detected in shallow soil, sediment and groundwater in this area indicating that PFAS have migrated through the soil profile to groundwater.

Aviation Fuel Farm

Analysis of groundwater collected from an existing well in the area confirmed the presence of PFAS in groundwater in this area at elevated concentration of PFHxS/PFOS sum exceeding the drinking water criteria.

Fire Station Building 7 and surrounds

Interview information from Defence personnel indicated that a foam capability fire truck was stationed here during the short duration whilst Exercise Kakadu was conducted in 2005. Concentrations of PFAS compounds were detected in shallow soil and sediment samples, however it was not detected in groundwater collected in the vicinity of Building 7.

Motor Transport Facility (northern end of compound and Building 707).

The Motor Transport Facility is considered a potential source due to a once off observation of waste AFFF being discharged at northern end of compound. Additionally, foam capability truck had been routinely stored in Building 707. Groundwater analysis of existing wells in the area confirm that concentrations of PFAS compounds were detected at both sample locations in the Motor Transport Facility.

11.2 Migration Pathways

PFAS may migrate through the environment in migration pathways as dissolved species with water

undergoing processes such as desorption, adsorption, leaching, or bioaccumulation.

Surface impacts may be associated with deposition/adsorption of PFAS to soil from use of AFFF or from

overland flow of waste water. PFAS may migrate in stormwater and surface water that flows along drainage

lines into nearby dams, wetlands, or other surface water bodies.

The results of the program identified the presence of PFAS in the sediment of drainage channels in the

vicinity of the OLAs, GPA and Motor Transport Facility. PFAS was identified in surface water collected north

of the runway, which may indicate an additional source area in the vicinity, or that PFAS is migrating along

these flow paths.



The presence of PFAS in the groundwater indicates that PFAS has migrated to the groundwater, likely to be via rainwater infiltration leaching PFAS present in the surface soils or pore water.

11.3 Exposure Pathways

The following exposure pathways are considered to be relevant:

Dermal contact or ingestion of impacted soil and sediment. Generally, direct contact with soils is limited

to the top 0.5 m, although construction or intrusive workers may disturb and be exposed to deeper soils.

Dermal contact or ingestion of impacted surface water or groundwater. Groundwater may be accessible

when extracted for uses such as domestic, irrigation or other purposes. Recreational use of surface

water in tributaries may occur off-property.

Ecological receptors present within the surface waters of tributaries and creeks. Aquatic receptors

present in Mission River may be exposed to impacted surface water.

Ingestion of food items grown with or within impacted surface water or groundwater. Such as,

recreational fishing within Mission River.

11.4 Receptors There are registered bores in the area for the extraction of water, which may be used for drinking water supply or agricultural use. The use of surface water or groundwater for drinking water is considered to be high since the local region is not connected to reticulated water supply.

Potential human health and ecological receptors for both on-property and off-property locations are

presented in Table 17 below. The receptors listed are those considered to be present either on- or off-

property, however, may not be at risk from exposure to PFAS contamination as an exposure pathway may

be incomplete.

Aquatic Ecological Receptors

Based on an initial screening of potential linkages between source, pathway and receptors and considering

the exposure pathways outlined in Section 11.3, the sub-set of potential receptors presented in Table 18 are

considered to represent potentially complete linkages between contamination sources and receptors.

Table 18 has not included possible off-property receptors given the absence of investigation results to

confirm if there are complete linkages between on-site sources and off-property receptors.



It is noted that there is a confirmed history of off-property use of groundwater and surface water for drinking

water supply at the Peppin community. Whilst access to preferred sampling locations onsite near to the

Peppin area was not possible due to a lack of access tracks, the nearest sampling locations in both

groundwater (MW026) and surface water (SW006) reported non-detect concentrations of PFAS. It is noted

that the Peppin Community is located some 3 km from the potential source areas on the property and is not

down-gradient of these potential source areas based on the available data of the inferred groundwater and

surface water flow directions.

Additionally, the adjacent mine may extract water for drinking water supply. Surface water sampling locations

closest to the western boundary adjoining the mine reported non-detectable concentrations of PFAS.

These potential receptor groups have not been included in Table 18 given the absence of off-property PFAS

data. However, it is considered that any future investigation / risk assessment would further consider all

potential receptors to further develop the understanding of the CSM in the event additional data will be

available for evaluation.

Table 18: Possible Receptors based on Potentially Complete Source, Pathway Receptor Linkages

On-Property

Intrusive, construction or maintenance workers (potential contact with contaminated soil/sediment/surface water/sediment). There is no adopted criteria available for this particular exposure scenario (ie intrusive, construction or maintenance workers), however it is noted that the soil and sediment concentrations detected were less than the adopted criteria for residential land use.

Domestic use of bore water.

It is noted that the limited sampling (one sample of each raw and treated water) at the water supply plant reported no detections of PFAS. Furthermore, the closest detection of PFAS to the water treatment plant is approximately 600m at the Motor Transport facility. Based on the inferred groundwater flow directions (westerly), the Motor Transport facility is likely to be cross gradient from the onsite water supply plant. However, the operation of the groundwater extraction system will induce a groundwater gradient towards the well during operation, however, the extent of the zone of influence and the depth (well screen) of this extraction, is not known.

Aquatic Ecological Receptors (fish etc living in wetlands and tributaries).


In terms of surface water concentrations, samples collected were reported non-detect concentrations other than in the stream on the northern side of the runway (SW13).



11.5 Data Gaps

The following key data gaps have been identified to consider in further assessment:

Delineation of the extent of PFAS in soil, sediment, surface water and groundwater in the vicinity and

down-gradient of the source areas.

Confirm specific use of groundwater from off-site wells and offsite surface water.

Review of existing information of the set-up and operation groundwater extraction system. Information

to evaluate could include well construction for pumping wells (particularly well screen interval), pumping

routines in different base occupancy situations, geological/hydrogeological information/data.

Use of Mission River for recreational purpose and/or for recreational fishing.

12.0 CONCLUSIONS AND RECOMMENDATIONS

12.1 Conclusions

The PSI was completed in accordance with the National Environment Protection (Assessment of Site

Contamination) Measure (ASC NEPM) (NEPC, 2013) including the collection of target environmental

samples.

The PSI historical review has refined the understanding of the history of AFFF use, storage and waste

disposal and identified potential primary sources of PFAS contamination. Given the nature of the property

being a “bare” Base with a small rotating workforce, firm details of the historical usage of AFFF could not be

established with a high degree of certainty based on the interviews conducted and as such, there may be

other primary source areas where AFFF was used, stored or disposed. Nonetheless, given the “bare” Base

nature of the property, there has been limited usage of AFFF in that conduct of foam training was limited to

one event during the Exercise Kakadu in 2005. Other AFFF usage has been associated with the servicing of

fire extinguishers and associated waste disposal.

The intrusive investigation including the collection of soil, sediment, surface water and groundwater at

targeted locations provided data to confirm that the operations undertaken have led to the presence of PFAS

contamination. The reported laboratory data suggests that PFAS contamination has migrated from the

identified sources areas, however the extent of this cannot be assessed based on the scope of the PSI. The

current understanding of source areas, potential migration pathways and receptors is presented in the CSM

in Section 11.0. Surface water sampling in the surface water streams on the western portion of the site

indicated non-detectable concentrations of PFAS. Conversely, some low detections of PFAS were reported

in the surface water sample collected on the northern side of the runway.

Given the remote location, the domestic (and all other use) water supply is drawn from bore water at the

Base. Sampling of the extracted bore water was completed as part of this PSI of both pre and post treated

water. The two samples collected did not detect concentrations of PFAS compounds above the laboratory

detection limit of 0.002 µg/L compared with the adopted drinking water criteria of 0.07 µg/L for PFOS/PFHxS.

On-property, bottled water is currently being supplied for drinking water purposes. Off-property, domestic

water supply is provided from either bore and/or surface water at the nearby Peppin residential camp which

is intermittently occupied. The source of water supply at the mining site could not be confirmed, but is likely

to include use of groundwater given the presence of registered bores onsite and the lack of reticulated water

in this locality.

During the reporting timeframe, Defence adjusted the scope of work to remove the re-categorisation task as

it was no longer required as part of the on-going Defence PFAS Program development.

12.2 Recommendations

Further investigation is recommended to progress the understanding of the contamination Conceptual Site

Model and the consequential assessment of potential risk. In developing the scope of work for a further

investigation, consideration of the data gaps identified in Section 11.5 is recommended.



In addition, a program of periodic monitoring of the domestic water supply at the extraction bores (pre-

treatment) and water treatment plant (post treatment) is recommended. This recommendation is made to

provide lines of evidence that the water supply is suitable for use.

It is recommended that the design of a groundwater monitoring program consider the following:

Review of existing information of the set-up and operation groundwater extraction system. The purpose

of the review is to enable an informed understanding of zone of groundwater influence through the

operation of the system. Consideration of the depth that groundwater is extracted for the water supply,

and the potential zone of influence from bore pumping could be evaluated to further assess the

suitability of the water supply.

Monitoring be undertaken on a quarterly basis for an initial period of one year. Then review the

frequency and extent of this monitoring once data has been evaluated.

. The sampling of the water supply bores is recommended to be completed at the lowest commercially

available analytical reporting limit such that there is the maximum concentration range between this

analytical reporting limit and the adopted drinking water criteria. As such, if concentrations are reported

in future monitoring (but below the adopted criteria), there is an opportunity to ensure mitigations are in

place to avoid consumption of impacted water.

APPENDIX A AFFF Summary

PSI – RAAF BASE SCHERGER

Project No. 1669283-003-R-Rev1 1

Appendix A Table 1: Summary of AFFF Storage, Use and Waste Disposal

Location Product Storage Use / Purpose Waste Disposal Incidents / Training Remediation

2005 Exercise Training Areas (unknown locations)

Fire trucks parked at Building 7 fire station during the exercise.

Building 707

3M Lightwater and / or Ansulite used during 2005 exercise.

AFFF stored in mobile equipment including fire trucks utilised during the 2005 exercise.

It is understood that a fire truck with foam capability was stored at RAAF Scherger prior to and after the 2005 exercise in Building 707

Training exercise for emergency fire response. Site staff had no first-hand knowledge of the amount of AFFF that may have been sprayed during the 2005 training exercise.

No information reported by Defence during interview.

The 2005 training exercise involved having full fire emergency training drills due to the presence of the F111 aircraft. Fire trucks were stationed at Building 7 during the exercise when not operational. The location where trucks would have sprayed foam during the 2005 exercise is not known, but it was reported that it may have included the taxiways, various Ordnance Loading Areas (OLAs) and General Purpose Apron (GPA).

None

Ordnance Loading Areas (OLAs), General Purpose Apron (GPA), Marine Hangers

3M Lightwater historically.

Ansulite currently

At the time of Base commissioning, it was intended that there would be 1 x 50 litre foam fire extinguisher at each of the following locations, totalling 15 extinguishers: OLAs (10), Marine Hangers (2) and the General Purpose Apron (3).

Extinguishers positioned here for Base preparedness in case of fire emergency.

Fire extinguishers were serviced annually and involved purging of the waste AFFF onto the ground at each storage location (i.e. OLAs, Marine Hangers and GPA).

The site personnel were not aware of fire incidents or fire training using the extinguishers were reported.

None

Ordnance Loading Area (OLA) 3

and


Ansulite Centralised locations for storage of all 15 x 50 L mobile extinguishers


Centralised location chosen for avoid deterioration of extinguishers in extreme weather and access to maintenance.

During extinguisher maintenance, waste AFFF was historically purged and discharged onto ground surface at either OLA3 or OLA8

Historical waste disposal involved discharge of AFFF to ground during extinguisher maintenance.

None, however it is understood that some of the pavement surface at OLA3 was resurfaced as part of asset maintenance.





Ansulite 1000 L bulk container (IBC) at time of inspection

15 x 50 L mobile fire extinguisher present at time of site inspection in 2016. 3 currently in service, 12 awaiting hydrostatic testing.

1 x 20 L drum foam (Solberg) at time of inspection

1000 L IBC stored here containing waste AFFF from servicing / purging of mobile fire extinguishers.

50 L mobile fire extinguishers either serviced at OLA8 or taken off Base and replaced with serviced extinguishers. Onsite servicing involved purging of AFFF into IBC.

1 x 20 L foam drum understood to be available for use with water fire truck in the event of emergency.

From approximately 2014, waste disposal practices of AFFF during extinguisher maintenance was changed. Waste AFFF was temporarily stored onsite in IBC.

IBC consequently transported offsite for appropriate disposal by Chubb.

No incidents identified, other than routine waste disposal as part of extinguisher servicing.

No fire training known to have occurred here.

None


As above for historical activities at GPA.

At time of inspection, it was noted that 1 x 50L mobile fire extinguisher (Ansulite) was present.

1 x 50 L mobile fire extinguisher.

Extinguishers positioned here for Base preparedness in case of fire emergency

Historical waste disposal (both 3M Lightwater and Ansulite) from servicing of fire extinguishers understood to have occurred at GPA.

No incidents identified, other than routine waste disposal as part of extinguisher servicing.

No fire training known to have occurred here.

None




Building 707 Warehouse

3M Lightwater (historical) / Ansulite – stored in fire truck historically parked in this Warehouse. Foam capability fire truck has been removed from Base and replaced with water-capability truck.

Ansulite stored in IBC associated with Lewie Fire servicing extinguisher program.

Since 2014, Lewie Fire has used this warehouse for the servicing of their contracted fire extinguishers. It is noted that Chubb Fire service other extinguishers.

Previously foam fire truck parked in this warehouse.

1000 L IBC stored here containing waste AFFF from servicing/ purging of mobile fire extinguishers.

Fire extinguishers are serviced annually and involve purging of the waste AFFF into IBC. Alternately, waste extinguishers are removed offsite and replaced with new extinguishers.

No anecdotal reports of fire incidents or fire training using the extinguishers were reported.

Sample HistoryWhere samples are submitted/analysed over several days, the last date of extraction and analysis is reported.A recent review of our LIMS has resulted in the correction or clarification of some method identifications. Due to this, some of the method reference information on reports has changed. However,no substantive change has been made to our laboratory methods, and as such there is no change in the validity of current or previous results (regarding both quality and NATA accreditation).

If the date and time of sampling are not provided, the Laboratory will not be responsible for compromised results should testing be performed outside the recommended holding time.

QC - Acceptance Criteria

QC Data General Comments

1. Laboratory QC results for Method Blanks, Duplicates, Matrix Spikes, and Laboratory Control Samples are included in this QC report where applicable. Additional QC data may be available on

request.

2. All soil results are reported on a dry basis, unless otherwise stated.

3. All biota results are reported on a wet weight basis on the edible portion, unless otherwise stated.

4. Actual LORs are matrix dependant. Quoted LORs may be raised where sample extracts are diluted due to interferences.

5. Results are uncorrected for matrix spikes or surrogate recoveries.

6. SVOC analysis on waters are performed on homogenised, unfiltered samples, unless noted otherwise.

7. Samples were analysed on an 'as received' basis.

8. This report replaces any interim results previously issued.

Please refer to 'Sample Preservation and Container Guide' for holding times (QS3001).

For samples received on the last day of holding time, notification of testing requirements should have been received at least 6 hours prior to sample receipt deadlines as stated on the Sample

Receipt Advice.

If the Laboratory did not receive the information in the required timeframe, and regardless of any other integrity issues, suitably qualified results may still be reported.

Holding times apply from the date of sampling, therefore compliance to these may be outside the laboratory's control.

**NOTE: pH duplicates are reported as a range NOT as RPD

mg/kg: milligrams per kilogram mg/L: milligrams per litre

ug/L: micrograms per litre ppm: Parts per million

ppb: Parts per billion %: Percentage

org/100mL: Organisms per 100 millilitres NTU: Nephelometric Turbidity Units

MPN/100mL: Most Probable Number of organisms per 100 millilitres

Dry Where a moisture has been determined on a solid sample the result is expressed on a dry basis.

LOR Limit of Reporting.

SPIKE Addition of the analyte to the sample and reported as percentage recovery.

RPD Relative Percent Difference between two Duplicate pieces of analysis.

LCS Laboratory Control Sample - reported as percent recovery.

CRM Certified Reference Material - reported as percent recovery.

Method Blank In the case of solid samples these are performed on laboratory certified clean sands.

In the case of water samples these are performed on de-ionised water.

Surr - Surrogate The addition of a like compound to the analyte target and reported as percentage recovery.

Duplicate A second piece of analysis from the same sample and reported in the same units as the result to show comparison.

Batch Duplicate A second piece of analysis from a sample outside of the clients batch of samples but run within the laboratory batch of analysis.

Batch SPIKE Spike recovery reported on a sample from outside of the clients batch of samples but run within the laboratory batch of analysis.

SRA Sample Receipt Advice

CP Client Parent - QC was performed on samples pertaining to this report

NCP Non-Client Parent - QC performed on samples not pertaining to this report, QC is representative of the sequence or batch that client samples were analysed within.

TEQ Toxic Equivalency Quotient

RPD Duplicates: Global RPD Duplicates Acceptance Criteria is 30% however the following acceptance guidelines are equally applicable:

Results <10 times the LOR : No Limit

Results between 10-20 times the LOR : RPD must lie between 0-50%

Results >20 times the LOR : RPD must lie between 0-30%

Surrogate Recoveries: Recoveries must lie between 50-150%-Phenols & PFASs 20-130%

1. Where a result is reported as a less than (<), higher than the nominated LOR, this is due to either matrix interference, extract dilution required due to interferences or contaminant levels within

the sample, high moisture content or insufficient sample provided.

2. Duplicate data shown within this report that states the word "BATCH" is a Batch Duplicate from outside of your sample batch, but within the laboratory sample batch at a 1:10 ratio. The Parent

and Duplicate data shown is not data from your samples.

3. Organochlorine Pesticide analysis - where reporting LCS data, Toxaphene & Chlordane are not added to the LCS.

4. Organochlorine Pesticide analysis - where reporting Spike data, Toxaphene is not added to the Spike.

5. Total Recoverable Hydrocarbons - where reporting Spike & LCS data, a single spike of commercial Hydrocarbon products in the range of C12-C30 is added and it's Total Recovery is reported

in the C10-C14 cell of the Report.

6. pH and Free Chlorine analysed in the laboratory - Analysis on this test must begin within 30 minutes of sampling.Therefore laboratory analysis is unlikely to be completed within holding time.

Analysis will begin as soon as possible after sample receipt.

7. Recovery Data (Spikes & Surrogates) - where chromatographic interference does not allow the determination of Recovery the term "INT" appears against that analyte.

8. Polychlorinated Biphenyls are spiked only using Aroclor 1260 in Matrix Spikes and LCS.

9. For Matrix Spikes and LCS results a dash " -" in the report means that the specific analyte was not added to the QC sample.

10. Duplicate RPDs are calculated from raw analytical data thus it is possible to have two sets of data.

Code Description

N11

Isotope dilution is used for calibration of each native compound for which an exact labelled analogue is available (Isotope Dilution Quantitation). The isotopically labelledanalogues allow identification and recovery correction of the concentration of the associated native PFAS compounds. Where the native PFAS compound does not have labelledanalogue then the quantification is made using the Extracted Internal Standard Analyte with the closest retention time to the analyte and no recovery correction has been made(Internal Standard Quantitation).

Q08The matrix spike recovery is outside of the recommended acceptance criteria. An acceptable recovery was obtained for the laboratory control sample indicating a sample matrixinterference

Sample HistoryWhere samples are submitted/analysed over several days, the last date of extraction and analysis is reported.A recent review of our LIMS has resulted in the correction or clarification of some method identifications. Due to this, some of the method reference information on reports has changed. However,no substantive change has been made to our laboratory methods, and as such there is no change in the validity of current or previous results (regarding both quality and NATA accreditation).

If the date and time of sampling are not provided, the Laboratory will not be responsible for compromised results should testing be performed outside the recommended holding time.

QC Data General Comments

1. Laboratory QC results for Method Blanks, Duplicates, Matrix Spikes, and Laboratory Control Samples are included in this QC report where applicable. Additional QC data may be available on

request.

2. All soil results are reported on a dry basis, unless otherwise stated.

3. All biota results are reported on a wet weight basis on the edible portion, unless otherwise stated.

4. Actual LORs are matrix dependant. Quoted LORs may be raised where sample extracts are diluted due to interferences.

5. Results are uncorrected for matrix spikes or surrogate recoveries.

6. SVOC analysis on waters are performed on homogenised, unfiltered samples, unless noted otherwise.

7. Samples were analysed on an 'as received' basis.

8. This report replaces any interim results previously issued.

Please refer to 'Sample Preservation and Container Guide' for holding times (QS3001).

For samples received on the last day of holding time, notification of testing requirements should have been received at least 6 hours prior to sample receipt deadlines as stated on the Sample

Receipt Advice.

If the Laboratory did not receive the information in the required timeframe, and regardless of any other integrity issues, suitably qualified results may still be reported.

Holding times apply from the date of sampling, therefore compliance to these may be outside the laboratory's control.

**NOTE: pH duplicates are reported as a range NOT as RPD

MPN/100mL: Most Probable Number of organisms per 100 millilitres

Dry Where a moisture has been determined on a solid sample the result is expressed on a dry basis.

LOR Limit of Reporting.

SPIKE Addition of the analyte to the sample and reported as percentage recovery.

RPD Relative Percent Difference between two Duplicate pieces of analysis.

LCS Laboratory Control Sample - reported as percent recovery.

CRM Certified Reference Material - reported as percent recovery.

Method Blank In the case of solid samples these are performed on laboratory certified clean sands.

In the case of water samples these are performed on de-ionised water.

Surr - Surrogate The addition of a like compound to the analyte target and reported as percentage recovery.

Duplicate A second piece of analysis from the same sample and reported in the same units as the result to show comparison.

Batch Duplicate A second piece of analysis from a sample outside of the clients batch of samples but run within the laboratory batch of analysis.

Batch SPIKE Spike recovery reported on a sample from outside of the clients batch of samples but run within the laboratory batch of analysis.

TEQ Toxic Equivalency Quotient

RPD Duplicates: Global RPD Duplicates Acceptance Criteria is 30% however the following acceptance guidelines are equally applicable:

Results <10 times the LOR : No Limit

Results between 10-20 times the LOR : RPD must lie between 0-50%

Results >20 times the LOR : RPD must lie between 0-30%

Surrogate Recoveries: Recoveries must lie between 50-150%-Phenols & PFASs 20-130%

1. Where a result is reported as a less than (<), higher than the nominated LOR, this is due to either matrix interference, extract dilution required due to interferences or contaminant levels within

the sample, high moisture content or insufficient sample provided.

2. Duplicate data shown within this report that states the word "BATCH" is a Batch Duplicate from outside of your sample batch, but within the laboratory sample batch at a 1:10 ratio. The Parent

and Duplicate data shown is not data from your samples.

3. Organochlorine Pesticide analysis - where reporting LCS data, Toxaphene & Chlordane are not added to the LCS.

4. Organochlorine Pesticide analysis - where reporting Spike data, Toxaphene is not added to the Spike.

5. Total Recoverable Hydrocarbons - where reporting Spike & LCS data, a single spike of commercial Hydrocarbon products in the range of C12-C30 is added and it's Total Recovery is reported

in the C10-C14 cell of the Report.

6. pH and Free Chlorine analysed in the laboratory - Analysis on this test must begin within 30 minutes of sampling.Therefore laboratory analysis is unlikely to be completed within holding time.

Analysis will begin as soon as possible after sample receipt.

7. Recovery Data (Spikes & Surrogates) - where chromatographic interference does not allow the determination of Recovery the term "INT" appears against that analyte.

8. Polychlorinated Biphenyls are spiked only using Aroclor 1260 in Matrix Spikes and LCS.

9. For Matrix Spikes and LCS results a dash " -" in the report means that the specific analyte was not added to the QC sample.

10. Duplicate RPDs are calculated from raw analytical data thus it is possible to have two sets of data.

Qualifier Codes/Comments

Code DescriptionN09 Quantification of linear and branched isomers has been conducted as a single total response using the relative response factor for the corresponding linear/branched standard.

N11

Isotope dilution is used for calibration of each native compound for which an exact labelled analogue is available (Isotope Dilution Quantitation). The isotopically labelledanalogues allow identification and recovery correction of the concentration of the associated native PFAS compounds. Where the native PFAS compound does not have labelledanalogue then the quantification is made using the Extracted Internal Standard Analyte with the closest retention time to the analyte and no recovery correction has been made(Internal Standard Quantitation).

General Comments

The analytical procedures used by the Environmental Division have been developed from established internationally recognized procedures such as those published by the USEPA, APHA, AS and NEPM. In house

developed procedures are employed in the absence of documented standards or by client request.

Where moisture determination has been performed, results are reported on a dry weight basis.

Where a reported less than (<) result is higher than the LOR, this may be due to primary sample extract/digestate dilution and/or insufficient sample for analysis. Where the LOR of a reported result differs from standard LOR, this may be due to high moisture content, insufficient sample (reduced weight employed) or matrix interference.

Anonymous = Refers to samples which are not specifically part of this work order but formed part of the QC process lot

CAS Number = CAS registry number from database maintained by Chemical Abstracts Services. The Chemical Abstracts Service is a division of the American Chemical Society.

LOR = Limit of reporting

RPD = Relative Percentage Difference

# = Indicates failed QC

Laboratory Duplicate (DUP) Report

The quality control term Laboratory Duplicate refers to a randomly selected intralaboratory split. Laboratory duplicates provide information regarding method precision and sample heterogeneity. The permitted ranges

for the Relative Percent Deviation (RPD) of Laboratory Duplicates are specified in ALS Method QWI -EN/38 and are dependent on the magnitude of results in comparison to the level of reporting: Result < 10 times LOR:

No Limit; Result between 10 and 20 times LOR: 0% - 50%; Result > 20 times LOR: 0% - 20%.

Method Blank (MB) and Laboratory Control Spike (LCS) Report

The quality control term Method / Laboratory Blank refers to an analyte free matrix to which all reagents are added in the same volumes or proportions as used in standard sample preparation. The purpose of this QC

parameter is to monitor potential laboratory contamination. The quality control term Laboratory Control Spike (LCS) refers to a certified reference material, or a known interference free matrix spiked with target

analytes. The purpose of this QC parameter is to monitor method precision and accuracy independent of sample matrix. Dynamic Recovery Limits are based on statistical evaluation of processed LCS.

This report is automatically generated by the ALS LIMS through interpretation of the ALS Quality Control Report and several Quality Assurance parameters measured by ALS. This automated

reporting highlights any non-conformances, facilitates faster and more accurate data validation and is designed to assist internal expert and external Auditor review. Many components of this

report contribute to the overall DQO assessment and reporting for guideline compliance.

Brief method summaries and references are also provided to assist in traceability.

Analysis Holding Time Compliance

Holding times for VOC in soils vary according to analytes of interest. Vinyl Chloride and Styrene holding time is 7 days; others 14 days. A recorded breach does not guarantee a breach for all VOC analytes and

should be verified in case the reported breach is a false positive or Vinyl Chloride and Styrene are not key analytes of interest/concern.

Holding time for leachate methods (e.g. TCLP) vary according to the analytes reported. Assessment compares the leach date with the shortest analyte holding time for the equivalent soil method. These are: organics

14 days, mercury 28 days & other metals 180 days. A recorded breach does not guarantee a breach for all non-volatile parameters.

If samples are identified below as having been analysed or extracted outside of recommended holding times, this should be taken into consideration when interpreting results.

This report summarizes extraction / preparation and analysis times and compares each with ALS recommended holding times (referencing USEPA SW 846, APHA, AS and NEPM) based on the sample container

provided. Dates reported represent first date of extraction or analysis and preclude subsequent dilutions and reruns. A listing of breaches (if any) is provided herein.

Brief Method SummariesThe analytical procedures used by the Environmental Division have been developed from established internationally recognized procedures such as those published by the US EPA, APHA, AS and NEPM. In house

developed procedures are employed in the absence of documented standards or by client request. The following report provides brief descriptions of the analytical procedures employed for results reported in the

Certificate of Analysis. Sources from which ALS methods have been developed are provided within the Method Descriptions.

Analytical Methods Method DescriptionsMatrixMethod

In house: A gravimetric procedure based on weight loss over a 12 hour drying period at 103-105 degrees C.

This method is compliant with NEPM (2013) Schedule B(3) Section 7.1 and Table 1 (14 day holding time).

Moisture Content EA055-103 SOIL

In-House. A portion of soil is extracted with MTBE. The extract is taken to dryness, made up in mobile phase.

Analysis is by LC/MSMS, ESI Negative Mode using MRM. PFOS is quantified using a certified, traceable standard

consisting of linear and branched PFOS isomers.

Per- and Polyfluoroalkyl Substances

General Comments




Where a reported less than (<) result is higher than the LOR, this may be due to primary sample extract/digestate dilution and/or insufficient sample for analysis.

Where the LOR of a reported result differs from standard LOR, this may be due to high moisture content, insufficient sample (reduced weight employed) or matrix interference.

When no sampling time is provided, the sampling time will default 00:00 on the date of sampling. If no sampling date is provided, the sampling date will be assumed by the laboratory and displayed in brackets without a

time component.

Where a result is required to meet compliance limits the associated uncertainty must be considered. Refer to the ALS Contact for details.



^ = This result is computed from individual analyte detections at or above the level of reporting

ø = ALS is not NATA accredited for these tests.

~ = Indicates an estimated value.

Key :

Analysis will be conducted by ALS Environmental, Sydney, NATA accreditation no. 825, Site No. 10911 (Micro site no. 14913).l

APPENDIX J Report Limitations

IMPORTANT INFORMATION RELATING TO THIS REPORT

The document (“Report”) to which this page is attached and which this page forms a part of, has been issued by Golder Associates Pty Ltd (“Golder”) subject to the important limitations and other qualifications set out below.

This Report constitutes or is part of services (“Services”) provided by Golder to its client (“Client”) under and subject to a contract between Golder and its Client (“Contract”). The contents of this page are not intended to and do not alter Golder’s obligations (including any limits on those obligations) to its Client under the Contract.

This Report is provided for use solely by Golder’s Client and persons acting on the Client’s behalf, such as its professional advisers. Golder is responsible only to its Client for this Report. Golder has no responsibility to any other person who relies or makes decisions based upon this Report or who makes any other use of this Report. Golder accepts no responsibility for any loss or damage suffered by any person other than its Client as a result of any reliance upon any part of this Report, decisions made based upon this Report or any other use of it.

This Report has been prepared in the context of the circumstances and purposes referred to in, or derived from, the Contract and Golder accepts no responsibility for use of the Report, in whole or in part, in any other context or circumstance or for any other purpose.

The scope of Golder’s Services and the period of time they relate to are determined by the Contract and are subject to restrictions and limitations set out in the Contract. If a service or other work is not expressly referred to in this Report, do not assume that it has been provided or performed. If a matter is not addressed in this Report, do not assume that any determination has been made by Golder in regards to it.

At any location relevant to the Services conditions may exist which were not detected by Golder, in particular due to the specific scope of the investigation Golder has been engaged to undertake. Conditions can only be verified at the exact location of any tests undertaken. Variations in conditions may occur between tested locations and there may be conditions which have not been revealed by the investigation and which have not therefore been taken into account in this Report.

Golder accepts no responsibility for and makes no representation as to the accuracy or completeness of the information provided to it by or on behalf of the Client or sourced from any third party. Golder has assumed that such information is correct unless otherwise stated and no responsibility is accepted by Golder for incomplete or inaccurate data supplied by its Client or any other person for whom Golder is not responsible. Golder has not taken account of matters that may have existed when the Report was prepared but which were only later disclosed to Golder.

Having regard to the matters referred to in the previous paragraphs on this page in particular, carrying out the Services has allowed Golder to form no more than an opinion as to the actual conditions at any relevant location. That opinion is necessarily constrained by the extent of the information collected by Golder or otherwise made available to Golder. Further, the passage of time may affect the accuracy, applicability or usefulness of the opinions, assessments or other information in this Report. This Report is based upon the information and other circumstances that existed and were known to Golder when the Services were performed and this Report was prepared. Golder has not considered the effect of any possible future developments including physical changes to any relevant location or changes to any laws or regulations relevant to such location.

Where permitted by the Contract, Golder may have retained subconsultants affiliated with Golder to provide some or all of the Services. However, it is Golder which remains solely responsible for the Services and there is no legal recourse against any of Golder’s affiliated companies or the employees, officers or directors of any of them.

By date, or revision, the Report supersedes any prior report or other document issued by Golder dealing with any matter that is addressed in the Report.

Any uncertainty as to the extent to which this Report can be used or relied upon in any respect should be referred to Golder for clarification.
