Executive Summary 

Environmental Strategies Pty Limited (ES) was commissioned by Prysmian Cables & Systems Australia Pty  Ltd  (Prysmian)  to  conduct  several Groundwater Monitoring Events  (GMEs)  as specified  in an ES (November 2013) Environmental Management Plan (EMP) for a portion of the site  located at 1 Heathcote Road, Liverpool NSW (the site). The site  location  is provided on Figure 1, Appendix A and the site layout in Figure 2, Appendix A.  

A  coolant  leak was  first  identified  in  February  2012 within  Factory  2  of  the  site with  an estimated 10,000 – 11,000L of  coolant  (hydrocarbon/water mixture)  lost  to  the  subsurface due to a fault that had developed within an in‐ground concrete pit. 

Prysmian have made a commitment to to conduct monthly monitoring of groundwater around the in‐ground pit for three (3) months. If, at the end of the three months of monitoring, the data trends indicate that the groundwater is not impacted by the leaking pit then less frequent monitoring will be justified. If groundwater either after the three (3) months of monitoring, or at any time following this, is shown to have been impacted by the contaminants of concern as triggered by the assessment criteria, then contingency options will be assessed. 

This report presents the results of the third GME. 

The results of the GME can be summarised as follows: 

Groundwater analytical results reported all contaminants of concern (total recoverable hydrocarbons (TRH), benzene, toluene, ethyl benzene, xylenes and naphthalene (BTEXN) and heavy metals) below laboratory detection limits and the adopted groundwater acceptance criteria (GAC) with the exception of copper and zinc which reported concentrations marginally above the GAC. ES consider that the concentrations of copper and zinc detected in groundwater are unlikely to pose a risk to human health and the environment and are likely representative of local background levels; and 

Given that no hydrocarbons were reported above the adopted groundwater criteria, this indicates that groundwater has not been impacted by the leaking coolant tank. 

Based on the above conclusions, and the results of the ES (June 2013) Supplementary Soil and Groundwater  Investigation,  ES  consider  that  the  coolant  leak  has  not  impacted  the underlying groundwater and recommends that no  further groundwater monitoring  (other than that conducted as part of the facility’s due diligence) is required.

1 Introduction 

1.1 Background 

Environmental Strategies Pty Limited (ES) was commissioned by Prysmian Cables & Systems Australia Pty Ltd (Prysmian) to conduct several Groundwater Monitoring Events (GMEs) as specified in an ES (November 2013) Environmental Management Plan (EMP) for a portion of the site located at 1 Heathcote Road, Liverpool NSW (the site). The site location is provided on Figure 1, Appendix A and the site layout in Figure 2, Appendix A. 

A coolant leak was first identified in February 2012 within Factory 2 of the site with an estimated 10,000 – 11,000L of coolant (hydrocarbon/water mixture) lost to the subsurface due to a fault that had developed within an in‐ground concrete pit. Following submission of a pollution incident report and sampling plan by MJM Environmental, Benbow Environmental (BE) were commissioned in July 2012 to undertake an Environmental Site Assessment (ESA) to investigate the extent of the release. 

Investigations of soil and groundwater were undertaken by Benbow Environmental Pty Ltd (BE) and ES in 2013.  

The results of the BE (January 2013) Environmental Site Assessment and the ES (June 2013) Supplementary Soil and Groundwater Investigation can be summarised as follows: 

Soil results as reported by BE showed that sample locations 7, 8 and 9 contained contaminant concentrations below health based criteria but exceed the NEPM (2013) Commercial/Industrial Management Limits for coarse soil at depths ranging between 2 and 4.5m below ground level (bgl); 

Impacted soils are localised to the southern and eastern portion of the in‐ground pit, between 2 and 4.5m bgl; 

The results of the ES soil investigation reported no exceedances  of hydrocarbons in soil above the adopted criteria (or concentrations above laboratory detection limits) at depths greater than 4.5m bgl; 

Groundwater analytical results reported all contaminants of concern (TRH, BTEX, PAH and heavy metals) below laboratory reporting limits and the adopted groundwater acceptance criteria (GAC) with the exception of copper and zinc, for which reported concentrations were marginally above the GAC. ES consider that the concentrations of copper and zinc detected in groundwater are unlikely to be related to the coolant use/spill. The concentrations of copper and zinc are likely representative of local background levels and are unlikely to pose a risk to human health and the environment; 

No TRH concentrations were reported above the adopted groundwater criteria indicating that groundwater had not been impacted by the leaking coolant tank; and 

The soil and groundwater around the tank were considered suitable for the continued commercial/industrial land use. 

Following the submission of BE (January 2013), ES (June 2013) and a Remedial Action Plan (RAP) prepared by Prysmian (June 2013), the NSW EPA voiced concerns that the identified petroleum hydrocarbons in soil may migrate to underlying groundwater.  

A letter report was prepared by ES (August 2013) discussing the hydrocarbon impacted soil and its potential to migrate to the underlying groundwater. ES concluded that the hydrocarbons in soil have not impacted underlying groundwater and are unlikely to migrate into the deeper soil profile. Nevertheless, as a due diligence measure, the Remedial Action Plan (RAP) prepared by Prysmian Group (June 2013) recommended that ongoing

groundwater monitoring be incorporated into the site’s EMP with a contingency plan should groundwater impact be detected from this event in the future. 

This GME aims to address the monitoring requirement presented in the ES (25 November 2013) EMP to show that the underlying groundwater remained unimpacted. 

Prysmian have made a commitment to to conduct monthly monitoring of groundwater around the in‐ground pit for three (3) months. If, at the end of the three months of monitoring, the data trends indicate that the groundwater is not impacted by the leaking pit then less frequent monitoring will be justified. If groundwater either after the three (3) months of monitoring, or at any time following this, is shown to have been impacted by the contaminants of concern as triggered by the assessment criteria, then contingency options will be assessed. 

This report presents the results of the third GME. 

1.2 Objective 

Within the original scope provided, the objective of the GME was to:

3 Sampling and Analysis Plan and Sampling Methodology 

This  section  outlines  the methodology  adopted  by  ES  during  the  GME.  This  section  also provides  details  on  the  sampling  and  analysis,  description  of  field  equipment  used, decontamination procedures,  field and  laboratory quality assurance and control,  laboratory analytical methods and sample preservation. 

3.1 Groundwater 

3.1.1 Groundwater Gauging, Purging and Sampling 

Groundwater gauging, purging and  sampling was  completed by ES’ Environmental Scientist Colin Biggs on 24th February 2014.  

Samples were  collected  from  the  five  (5) wells  in  the vicinity of  the  reported  coolant  leak. Refer to Figure 3, Appendix A. 

Prior  to  sampling,  all wells were  gauged with  an  interface probe  to measure  groundwater levels and detect the presence of phase‐separated hydrocarbons (PSH). All monitoring wells were  then  purged  using  a  peristaltic  pump  to  ensure  minimal  losses  of  volatile  organic compounds. 

Water quality parameters recorded included pH, redox potential (Eh), electrical conductivity, dissolved  oxygen  and  temperature.  All  wells  were  purged  until  groundwater  parameters stabilised to within 10% of the previous reading. 

Samples  were  placed  directly  into  appropriately  preserved  laboratory  supplied  sampling containers.  The  sample  for  metals  analysis  was  filtered  in  the  field  using  a  0.45micron millipore filter unit prior to analysis. 

Disposable tubing was used at each monitoring well and the interface probe was thoroughly decontaminated between gauging events with a phosphate  free detergent  (Decon 90) and rinsed  with  potable  water.  Field  records  of  purging  and  sampling  event  are  provided  in Appendix C. 

3.1.2 Field QA/QC 

The following procedures were followed during fieldwork to ensure quality control: 

Water samples were collected in laboratory supplied bottles with Teflon seals; 

Samples  were  collected  from  disposable  equipment  to  prevent  cross  contamination between sampling locations; 

Samples were placed in an ice‐filled esky to keep them below 4oC in accordance with US EPA SW 846 and AS4482‐2 (2005); and 

Samples were transferred to the laboratory under a completed chain‐of‐custody.

4 Field Quality Assurance and Quality Control (QA/QC) 

4.1 Chain of Custody 

Samples were  transferred  to  the  laboratory under chain‐of‐custody procedures. The details included on the chain‐of‐custody forms included the following: 

Job name and number  Date results are required  List of samples  Preservation method  Analysis required  Release signature and date  Date sampled  Acceptance signature and date 

4.2 Statement of Duplicate Frequency 

The following are QA/QC samples were collected for this project: 

DUP1 and TRIP1 were a groundwater intra‐laboratory and inter‐laboratory duplicate of MW4. 

All RPDs  for groundwater were within acceptable  ranges as  shown  in Table 1, Appendix D with  the exception of  the  samples  listed below,  calculated RPDs were  reported within  the acceptable range for all primary, duplicate and triplicate samples. 

Zinc (145%) between MW4 and TRIP1. 

Where  contaminant  concentrations  were  more  than  ten  times  the  laboratory  limit  of reporting,  the  RPD  exceedances  were  likely  to  be  caused  by  sample  heterogeneity. Furthermore,  no  elevated  RPD  value  for  any  primary  sample,  intra‐laboratory  or  inter laboratory sample, exceeded the GAC, and therefore ES considers the elevated RPD values do not affect the validity of the data collected 

Overall,  there  is an acceptable  level of agreement between original and duplicate  samples indicating  that  field  procedures  were  adequate  in  obtaining  representative  samples  and minimising the potential for cross‐contamination. 

4.3 Background Sample Results 

Background samples were not collected as part of this investigation. 

4.4 Rinsate Sample Results 

A  rinsate  sample was  collected  from  the  final decontamination of  the  interface probe and purged water bucket.  The  rinsate  sample  reported  all  analytes below  laboratory detection limits  indicating  that  adequate  decontamination  procedures,  dedicated  sampling materials and  best  practice  sampling  methods  were  adequate  to  prevent  the  potential  for  cross contamination to occur during groundwater sampling. 

4.5 Trip Blank 

Trip Blank samples were not collected as part of this investigation. 

4.6 Trip Spike Results 

Trip Spike samples were not collected as part of this investigation.  

4.7 Field Instrument Calibration 

Field instruments were calibrated prior to use on site.

6 Assessment Criteria 

6.1 Rationale for Selection of Water Assessment Criteria 

In accordance with the NEPM (2013) Schedule B(6) The Framework for Risk Based Assessment of Groundwater  Contamination  it was  necessary  to  determine  the  relevant  environmental values and hence appropriate guideline assessment criteria for the site. 

To  determine  the  most  appropriate  groundwater  guideline  the  following  environmental values have been  considered  and  are presented  in Table 6.2. These have been  referenced from  Appendix  2  of  NSW  DEC  (2007)  Guidelines  for  the  Assessment  and Management  of Groundwater Contamination and the NEPM (2013) Schedule B (6).

Environmental Values 

ES Comment 

Aquatic Ecosystems (Freshwater) 

The  closest  surface water  receptor  is  the Georges River  located along  the western  boundary  of  the  site.  The  Georges  River would  be  classed  as  a beneficial receptor of groundwater and should be protected. This is classed as a freshwater environment. 

Human Uses (Drinking Water) 

No  registered  groundwater bores  for domestic use were  identified within 500km of the site. EC measurements of the groundwater monitoring bores indicated a TDS <2,000mg/L. This suggests it may be a potable resource and however, given the site  is  located  in a  largely  industrial based area near to the  Georges  River  it  is  unlikely  a  groundwater  bore  would  be  installed onsite, or  in  the  vicinity which would produce  sufficient yields  to warrant abstraction for use.  

Agricultural Use – Stock Watering and Irrigation 

A  review  of  groundwater  bore  information  indicates  that  superficial groundwater within the area is potentially suitable for either stock watering or irrigation purposes. 

Cultural and Spiritual Values 

ES is not aware of any cultural / spiritual values associated with the surface and / or groundwater in this area. 

Bearing  the above  in mind, ES consider  that  for  the protection of environmental values  the most appropriate guideline values to be applied  in relation to the site  is the ANZECC (2000) Freshwater Criteria using 95% Limit of Protection and Revised (NEPM) 2013 – Assessment of Site Contamination Schedule B(1) Assessment of Groundwater Contamination. 

Adopted  criteria  presented  in  Table  6.3  below  lists  the  adopted  groundwater  assessment criteria for the site.

 Table 7.2 indicates the following groundwater conditions:  The temperature of the groundwater ranged from 22.0 to 24.9oC;  pH ranged from 5.50 to 5.92 pH units indicating slightly acidic groundwater conditions;  Dissolved  oxygen  in  the  groundwater  ranged  from  0.22  and  1.61  ppm  indicating 

anaerobic conditions in monitoring wells MW4 & MW5 and aerobic conditions in MW1, MW3 and MW3; 

ORP  (oxidation  reduction  potential)  levels  measured  from  199  to  244mV  (using  a Ag/AgCl electrode), which  indicates oxidising conditions. ORP (or Redox)  is a measure of a water system’s capacity to either release or gain electrons  in chemical reactions. The  process  of  oxidation  involves  losing  electrons  while  reduction  involves  gaining electrons; and 

Conductivity  levels  were  between  313  and  767  (µS/cm),  which  indicates  fresh groundwater conditions. 

The following presents a summary of results for groundwater samples. Result summary tables are included in Appendix B, with copies of laboratory certificates included in Appendix E.

7.3 Groundwater Analytical Results 

7.3.1 Heavy Metals 

Concentrations  of  heavy metals  in  all  groundwater  samples  submitted  for  analysis  were reported below the GAC with the exception of: 

Concentrations of copper in MW1 (2µg/L) and MW4 (4µg/L); and   Concentrations of zinc in MW1 (23µg/L). 

7.3.2 BTEXN 

Concentrations of BTEXN  in all groundwater  samples  submitted  for analysis were  reported below laboratory detection limits and the adopted GAC. 

7.3.3 TRH 

Concentrations  of  TRH  in  all  groundwater  samples  submitted  for  analysis  were  reported below laboratory detection limits and the adopted GAC.  

7.3.4 Discussion 

The  results  of  this  investigation  indicate  that  no  detectable  petroleum  hydrocarbon contamination  was  present  in  any  of  the  up‐gradient  or  down‐gradient  monitoring  well locations  above  the  adopted  groundwater  acceptance  criteria  (GAC).  However, concentrations  of  copper  and  zinc  were  reported  above  the  GAC.  Copper  and  zinc  are ubiquitous within  the  urban  environment  and  commonly  used  as  a  pigment  in  paints,  in metallic  structures,  electrical  wiring,  underground  services  and  pipes.  It  is  considered therefore, that the identified groundwater copper and zinc concentrations are potentially the result of long‐term weathering of metal‐based paints, metal coatings, metallic structures and pipes  in the  local urban area, and not necessarily attributable onsite contamination sources i.e associated with the copper drawing process. Furthermore, the site surface is sealed and no potentially pathways to the subsurface were evident at the time of the visit.  

The recent groundwater monitoring data was compared  to  that of  the previous GME event that  occurred  in  September  2013  and  December  2013  and  Table  3  Appendix  B  shows  a comparison of analytical results from these two rounds. 

ES consider that the concentrations of copper and zinc detected in groundwater are unlikely to pose a risk to human health and the environment.

8 Conclusions and Recommendations 

8.1 Conclusions 

The  following  conclusions  can  be made  from  the GME  conducted  at  the  site  located  at  1 Heathcote Road, Liverpool: 

Groundwater analytical results reported all contaminants of concern (TRH, BTEXN and heavy metals) below laboratory detection limits and the adopted groundwater acceptance criteria (GAC) with the exception of copper and zinc which reported concentrations marginally above the GAC. ES consider that the concentrations of copper and zinc detected in groundwater are unlikely to pose a risk to human health and the environment and are likely representative of local background levels; 

No TRH concentrations were reported above the adopted groundwater criteria indicating that groundwater has not been impacted by the leaking coolant tank; and 

This GME is the third monitoring event after the preparation of the RAP, however, it represents the fourth round of monitoring (conducted in February 2014) and confirms the findings of the ES (June 2013) report, that the groundwater has not been impacted by the leaky coolant tank. 

8.2 Recommendations 

Based on the above conclusions, and the results of the ES (June 2013) Supplementary Soil and Groundwater  Investigation,  ES  consider  that  the  coolant  leak  has  not  impacted  the underlying groundwater and recommends that no  further groundwater monitoring  (other than that conducted as part of the facility’s due diligence) is required. 

8.3 Extent of Uncertainties in the Results 

The sampling methodologies used by ES during this assessment have been designed to  limit uncertainty in the results. ES is confident that the results of this assessment give an accurate representation of the current status of the site but note that  in all subsurface  investigations the potential  remains  for  variation between  sampling points and  conditions different  from that reported here may exist on site.

Report Comments:

Asbestos ID was analysed by Approved Identifier: Not applicable for this job

Asbestos ID was authorised by Approved Signatory: Not applicable for this job

INS: Insufficient sample for this test PQL: Practical Quantitation Limit NT: Not tested

NA: Test not required RPD: Relative Percent Difference NA: Test not required

<: Less than >: Greater than LCS: Laboratory Control Sample

Quality Control Definitions

Blank: This is the component of the analytical signal which is not derived from the sample but from reagents,

glassware etc, can be determined by processing solvents and reagents in exactly the same manner as for samples.

Duplicate : This is the complete duplicate analysis of a sample from the process batch. If possible, the sample

selected should be one where the analyte concentration is easily measurable.

Matrix Spike : A portion of the sample is spiked with a known concentration of target analyte. The purpose of the matrix

spike is to monitor the performance of the analytical method used and to determine whether matrix interferences exist.

LCS (Laboratory Control Sample) : This comprises either a standard reference material or a control matrix (such as a blank

sand or water) fortified with analytes representative of the analyte class. It is simply a check sample.

Surrogate Spike: Surrogates are known additions to each sample, blank, matrix spike and LCS in a batch, of compounds

which are similar to the analyte of interest, however are not expected to be found in real samples.

Laboratory Acceptance Criteria

Duplicate sample and matrix spike recoveries may not be reported on smaller jobs, however, were analysed at a frequency

to meet or exceed NEPM requirements. All samples are tested in batches of 20. The duplicate sample RPD and matrix

spike recoveries for the batch were within the laboratory acceptance criteria.

Filters, swabs, wipes, tubes and badges will not have duplicate data as the whole sample is

generally extracted during sample extraction.

Spikes for Physical and Aggregate Tests are not applicable.

For VOCs in water samples, three vials are required for duplicate or spike analysis.

Duplicates: <5xPQL - any RPD is acceptable; >5xPQL - 0-50% RPD is acceptable.

Matrix Spikes, LCS and Surrogate recoveries: Generally 70-130% for inorganics/metals; 60-140%

for organics and 10-140% for SVOC and speciated phenols is acceptable.

In circumstances where no duplicate and/or sample spike has been

reported at 1 in 10 and/or 1 in 20 samples respectively, the sample

volume submitted was insufficient in order to satisfy

laboratory QA/QC protocols.

When samples are received where certain analytes are outside of

recommended technical holding times (THTs), the analysis has

proceeded. Where analytes are on the verge of breaching THTs,

every effort will be made to analyse within the THT or as

soon as practicable.
