CONTAMINATION ASSESSMENT OFFISHING SMACK PUBLIC HOUSE,including remediation guidance.
SUMMARY
The Fishing Smack Public House is located within the Roding Valley/Abbey Road Riverside
Conservation Area and was built in 1901 in a mock Tudor style. LBBD Council suggests the
building is worthy of protection. The premises includes a low-headroom basement that has,
on occasions, become flooded by ingress of groundwater of either tidal origin or due to heavy
rain. Being within the Conservation Area there is a planning presumption for retention of the
building, other than where the cost of such retention renders any use to be economically non-
viable.
Adjoining the Fishing Smack Public House immediately to the west was Barfords Chemical
Works. The company ceased trading around 2003. Prior to this time it was discovered that
xylene and possibly petroleum hydrocarbons had been lost to the ground and caused ground
contamination that required remediation.
LBBD Environmental Protection Team investigated on at least three occasions and closed
the public house under Emergency Action on one occasion, because of the concentration of
xylene vapour in the basement. The public house closed in 2003.
The Barfords Chemicals site was remediated and a report produced by WSP, but problems
persisted at the Fishing Smack Public House. Further remediation was taken over by
Barfords Chemicals, which closed soon afterwards. The Environment Agency has no record
for the completion of this work.
There is no assurance that under certain circumstances of tide and heavy rain, contaminated
groundwater may affect the building again. Without such assurance being in place, there
remains a Major risk to human health (fire or explosion) at the Fishing Smack Public House
site while a gas-permeable basement or other confined space remains.

ii DRAFT 2
The continued presence of polluted groundwater under any building on site will be
unacceptable to the Environment Agency.
A site investigation was undertaken for Adige (UK) Ltd on behalf of Steinbex in September
2005, involving the construction of three boreholes and monitoring of nine existing monitoring
wells. The investigation found severely contaminated groundwater (at around 2.5 metre
below ground level) in two boreholes and very high PID (hydrocarbon vapour) readings in the
atmosphere of three of the boreholes. The contamination comprised a significant floating
layer of free product (LNAPL - light non-aqueous phase liquid) comprising xylenes and
toluene with other hydrocarbons (other BTEX, petroleum and diesel range mineral oil). No
inorganic contamination was indicated. To give an indication of the voracity of the solvent,
the plastic standpipe in one borehole was described as discoloured and evidently degraded.
Four options are offered for consideration by Steinbex and engineering/architectural
professionals together with LBBDC and the Environment Agency. These range from
retention of the site in its present form until such time as remediation of Barfords (and the
site) is completed to forming a barrier around the site within which new build can take place.
At the “Draft 2” stage of this report, no recommendation is made, the report being for
consideration with the statutory authorities.

CONTAMINATION ASSESSMENT OFFISHING SMACK PUBLIC HOUSE,including remediation guidance.
1. INTRODUCTION
Mr M Khan of Steinbex Limited commissioned National Britannia Limited to assess the
information available on the contaminative status of the Fishing Smack Public House site at
92 Abbey Road, Barking. No site visit is required. A conceptual, qualitative model of hazards
and associated risks will be developed.
Thereafter, to consider the options for retention or otherwise of the present structures on the
site, with due regard to the hazards potentially present on the site and the residual risk to
human health of each of the described options. Because of the findings of the investigation,
this “Draft 2” report offers options for the site for discussion with statutory authorities, and
does not recommend a particular option.
National Britannia is not required to provide detailed engineering design of any option, nor
detailed costs associated with any option or the remediation requirements associated with
any option. The Desktop assessment was carried out by Dr Ron Edwards, Chief Chemist to
National Britannia Limited, an IEMA registered Environmental Auditor of considerable
experience.
The consideration, conclusions and recommendations of this report are based on the
information gained by document searches and that made available by the client. The
interpretation includes consideration of legislation, regulations, Codes of Practice, guidance
notes and current research opinion. Revision of legislation and the potential for litigation or
other action against owners/operators continues to develop, and this report endeavours to
anticipate any environmental problems that may arise within the foreseeable future.
Contaminated Land legislation contained in Part IIA of the Environmental Protection Act 1990

may have considerable impact on sites that may be contaminated, but there is currently little
associated Case Law. The environmental situation of the site may be subject to varied or
additional interpretation by statutory authorities and others, for which National Britannia
cannot be responsible.
2. DESCRIPTION OF THE SITE
The Fishing Smack Public House covers a large part of the site of interest, the remainder
being hardstanding, beer garden and outbuildings. The site is located within the Roding
Valley/Abbey Road Riverside Conservation Area as originally proposed by the Planning and
Development Committee of the Council in 1995. The report to committee describes the
Fishing Smack Public House as having been built in 1901 in a mock Tudor style, and
suggests the building is worthy of protection. The premises includes a low-headroom
basement that has, on occasion, become flooded by ingress of groundwater of tidal origin
and/or due to heavy rain. The building is not a Listed Building. However, being within the
Conservation Area there is a planning presumption for retention of the building, other than
where the cost of such retention renders any use to be economically non-viable.
Adjoining the Fishing Smack Public House immediately to the west was Barfords Chemical
Works. The company ceased trading around 2003. Prior to this time it was discovered that
xylene and possibly petroleum hydrocarbons (petrol) had been lost to the ground and caused
ground contamination that required remediation.
3. CONTAMINATION OF BARFORDS CHEMICALS, ANDCONSEQUENCES FOR FISHING SMACK PUBLIC HOUSE.
Barfords Chemicals was licenced to carry out processes under Integrated Pollution Control
regulations by the Environment Agency, Hatfield. By 1999 it had become apparent that tanks
or pipelines present at the chemical works had leaked xylene and possibly petrol into the
ground. Chemical odours had been detected in the basement of the public house at times
when the basement flooded. Under the supervision of the Environment Agency, Barfords
commissioned a study by WSP in July 1999 to ascertain the extent of the contamination.
The original investigation comprised a soil vapour survey (SVS) that encountered greater
than 2000 ppm (parts per million) of flammable compounds in 19 out of 24 probe holes. The
three probes located along the boundary with the public house all recorded greater than 2000
National Britannia Limited_________________________________________________________________________
3
ppm, while two of three probe holes within the public house site found significant levels of
flammable compounds (75 and 37 ppm).
Following these initial investigations, seven boreholes were constructed in September 1999,
BH4 and BH6 being within the public house site. BH4 returned 1200 mg/kg of volatile
organics (quantified as petrol) in the soil and 2900 ug/l petrol in the water. These represent
very significant concentrations.
The company initiated remediation of the chemical works land, comprising hydraulic
containment, removal of oil floating on the water surface (known as LNAPL - Light Non-
Aqueous Phase Liquid) and soil vapour extraction. An interim report of June 2000 by WSP
indicated that the remediation had been successful in greatly reducing the levels of
contamination, and with no measurable LNAPL detectable in the boreholes. A report
describing the results of the remediation is held by the Environment Agency (contact David
Farlie at Environment Agency, Hatfield. The officers involved in 2000 were Ian Moxan and
Nicola Ingrey, neither of which are now available).
Unfortunately, following a period of heavy rain and high tide, groundwater carrying volatile
organic chemicals entered the basement of the Fishing Smack Public House, and
evaporation of these flammable materials generated vapours in the basement that presented
a risk of fire or explosion.
The London Borough of Barking and Dagenham (LBBDC), Environmental Protection Team
closed the public house under emergency action because of the risk posed by this potential
explosion hazard. Enquiries of Rob Williams of this team (in September 2005) indicated that
“very high levels of xylene vapour was present in the basement”. Also that there were two or
three such incidents which occurred when heavy rainfall and high tides gave high
groundwater level (which entered the basement) with high levels of solvent. The public
house was closed by Environmental Protection Department “for health and safety” reasons.
Following on from these events Barfords Chemicals commissioned abstraction boreholes
along the boundary with the Fishing Smack Public House to further remediate the situation.
In around 2002, Barfords took direct control of the remediation from WSP. Barfords
Chemical ceased trading soon afterwards, and the Environment Agency have not received
any further information on whether the work was completed or whether it was successful in
reducing levels.

The Fishing Smack Public House closed in March 2003 and has been vacant since that time.
No further observations, investigations or assessments have been carried out on the public
house site by the Environmental Protection Team or the Environment Agency. It is not
known if other incidents of flammable vapour build-ups in the basement have occurred, but
there is no reason to conclude that the problem has gone away.
In order to ascertain the state of the site, InnSpired Pubs plc, owners of the Fishing Smack
Public House, commissioned Environ to carry out a site investigation in April 2002.
In order to describe the present state of the ground and groundwater, Steinbex
commissioned a site investigation by Adige (UK) Limited in September 2005.
4. SITE INVESTIGATION BY ENVIRON, APRIL 2002.
Environ carried out an Environmental Investigation on the Fishing Smack Public House in
April 2002 for InnSpired Pubs plc.
Five boreholes were constructed on the site, with three of these prepared for soil vapour and
groundwater collection and analysis. Two boreholes from the previous WSP investigation of
1999 were also used.
Made Ground was encountered in all boreholes to between 1.0 and 1.2 metre below ground
level. This material comprised soft silty clay with brick fragments. No visual contamination
was observed. A soft Alluvial Clay containing gravel was located beneath this Made Ground
to around 6 metre depth.
Groundwater was located at around 2.0 to 2.2 metre below ground level in all boreholes.
Groundwater was considered to be in hydraulic continuity across the site and the River
Roding, and the findings of WSP indicated it rose and fell with the tide.
Soil Vapour Headspace Analysis on the boreholes found significant readings for all
boreholes. Unfortunately the way in which the wells were constructed may have excluded
collection of water from the Made Ground. The readings will have originated from dissolved
solvent in the body of the groundwater and may have excluded any solvent layer that may be
floating on the groundwater. It is clear from the observed groundwater levels that the
National Britannia Limited_________________________________________________________________________

conditions were not those that had historically led to flammable vapour problems in the
basement.
None of the soil samples that were tested returned any significant results for any common
contaminant, for Total Petroleum Hydrocarbon or for Volatile Organic Compounds or BTEX (a
measure that includes xylene). Analysis of groundwaters found exceedances for Total
Petroleum Hydrocarbons in all samples (up to 7200 ug/l against a guideline used of 600 ug/l).
The Environ report describes the geology and hydraulic (groundwater) conditions of the site
in reasonable detail. However, the extent of study, groundwater conditions and timing of the
chemical investigation does little to clarify the hazard from solvent or petrol vapours, only to
indicate that petrol contamination of groundwater on the site persists to some extent.
5. SITE INVESTIGATION BY ADIGE (UK) LTD, SEPTEMBER2005.
A plan of the site showing approximate locations of boreholes, borehole logs and analysis
results are included as Appendix A. Existing monitoring boreholes have been assigned
codes of BHA to BHI, and newly constructed boreholes SE1 to SE3.
Construction of boreholes SE1 to SE3 found between 1.0 m and 1.5 m of Made Ground (of
topsoil, gravel and fragments of brick, glass and ceramics over sandy, silty, clay with gravel
and brick fragments) over between 1 m and 1.5 m of Silty, Gravelly Clay, over Silty, Sandy
Gravel to the base at 2.7 to 3.5 m BGL. Groundwater was found in the Gravel consistently at
3.0 m below ground level. The groundwater in borehole SE3 was visibly contaminated and
possessed a hydrocarbon odour.
Nine existing boreholes were monitored for hydrocarbon vapours with a PID instrument.
Three boreholes, B,C and H generated results of >9999 ppm, while others returned low
readings. The groundwater in these boreholes was sampled and boreholes B and C were
found to contain 10 mm of free product (LNAPL – light non-aqueous phase liquid) while H
contained 50 mm of LNAPL.
Soil samples from borehole SE3 were submitted to Alcontrol Laboratories for a general range
of potential contaminants at depths of 0.3 m and 2.0 m and for BTEX contaminants from 3.5
m depth. The other boreholes were sampled but not submitted for analysis. No significant
contamination was found except for organic compounds at 3.5 m depth, below the water

table. Contamination here comprised 498 mg/kg xylenes, 1900 mg/kg toluene, 54 mg/kg
benzene and 73 mg/kg ethylbenzene.
Groundwater samples were submitted for analysis of organic compounds from boreholes C,
F and H. Significant xylene was found in borehole C but not borehole F. Water from
borehole H was subjected to detailed analysis for organic compounds. Total Petroleum
Hydrocarbon content reached 280000 mg/l, with Gasoline Range Organics at 55500 mg/l and
Diesel Range Organics at 269000 mg/l. Xylenes reached 4473 mg/l, 17800 mg/l toluene,
743 mg/l benzene, 669 mg/l ethylbenzene and other compounds.
6. SOURCE OF CONTAMINATION, MOBILITY ANDPATHWAY.
6.1 Petrol and/or xylene affecting groundwater beneath the site.
Source.
As an example of the environmental aspects of potential contaminants, xylene is immiscible
and lighter than water (therefore floats) and has a Low Flash Point (32o C) and an explosive
range of 1.1 to 7.0% in air. It is Stable and Flammable. It is Harmful if swallowed, inhaled or
absorbed through the skin, and has a long-term exposure limit (8-hour) of 50 ppm. It will
disrupt many plastics including natural and other rubbers.
The xylene and toluene will have originated from leakage at Barfords Chemicals at some time
up to 1999, and may persist in soil and on groundwater.
Petrol and diesel, in the quantities present, will have originated from leakage at Barfords
Chemicals or other premises at some time up to 1999 or later, and may persist in soil and on
groundwater.
Mobility.
Xylene, toluene, diesel and petrol are mutually soluble in each other, are highly mobile and
be transmitted floating on, dissolved or occluded in groundwater from contaminated soil and
be moved around by tidal variation in the river, or by occasional floodwater.
National Britannia Limited_________________________________________________________________________
7
Pathways.
Movement through permeable ground, especially the Made Ground and gravel beds or
lenses. Floating solvent or petrol may vaporise into confined spaces (such as the basement)
and build vapour concentrations that are flammable or explosive.
Receptor.
Human health could be affected by direct contact with xylene, toluene, benzene, diesel or
petrol on water or in soil.
Human health could be affected by fire or explosion of flammable atmosphere in the
basement or other confined spaces.

8. SITE ASSESSMENT
Conceptual Model.
History of the site indicates that leakage occurred from tanks or pipelines at Barfords
Chemicals and contaminated soil and groundwater at the Fishing Smack Public House with
xylene and possibly petrol. It is evident that solvent floating on the water surface evaporated
National Britannia Limited_________________________________________________________________________
8
in to the confined space of the basement of the public house, generating a potentially
flammable or explosive atmosphere. This may be ignited by a flame or electrical switching.
Soil affected by xylene or petrol on the groundwater has become contaminated. Disturbance
of the soil may bring demolition or construction workers or the public into contact with
affected soil or may inhale fumes.
Remediation.
While a Source of xylene and/or petrol previously existed (up to 2002) it is clear that previous
remediation was ineffective in adequately modulating that Source. Protection of any building
on the site is essential and must be effective. Further remediation of the vicinity of Barfords
is required.
Residual Risk.
Solvents (such as xylenes and toluene), petrol and diesel remain in soil and are available for
migration on groundwater during exceptional tidal or flooding events. The remaining risk to
the public house by build up of flammable vapours in the basement comprises a Major risk.
Removal of areas of previously impermeable hardstanding or floor slabs at Barfords
Chemicals site, could introduce a new migration route, through percolation of rain water and
transport of solvents or petrol to the groundwater.
9. PROTECTION OF THE FISHING SMACK SITE.
Premise.
The following options for safe use of the Fishing Smack Public House site are based on two
considerations:
• The remediation of Barfords Chemicals site has been not been successful in
adequately reducing the hazard on the public house site such that, in certain
circumstances (high tide and heavy rain), the risk of fire or explosion in the
unprotected basement remains a Major risk.
• That the basement is presently open to ingress of groundwater under certain
circumstances.
National Britannia Limited_________________________________________________________________________
9
Option 1: Await remediation of the Barfords site before developing the Fishing SmackPublic House site.
The Fishing Smack site could be retained in its current state, with or without retention of the
building, until the adjoining Barfords site is validated as being adequately remediated. As
part of this process, the Fishing Smack Public House site would be included in this
remediation process.
Any building built within the site, with or without a basement would require to be protected
from any unforeseen entry of pollution, by means of a constructed water and vapour ingress
protection system and passive venting from beneath and alongside this.
Option 2: Full tanking of basement and replacement and protection of some ground onthe site.
This option requires an engineering solution whereby the existing basement may be made
impermeable to groundwater and soil atmosphere. This would involve the construction of
basement walls and floor either inside or exterior to the existing walls to a standard that
affords full protection. Any construction would need to use such materials and mode of
construction as to guarantee that ingress of hydrocarbons and vapour will not occur over the
full period required to remediate the adjoining ground. It would be necessary to collect and
treat free phase from the surrounding groundwater on site and it is very unlikely that the
Environment Agency would permit any venting of vapours or soil atmosphere to air.
Option 3: Sealing the basement.
The basement may be filled and sealed. The building would require to be protected from any
build up of potentially flammable vapours within the filled basement by gas proof membrane
and a system of passive or forced ventilation.
It is probable that this solution would leave an undesirable and potentially hazardous situation
in the filled basement and the surrounding ground unless the venting system could be
guaranteed to function adequately in perpetuity. It is highly unlikely that the statutory bodies
would accept a solution that allowed contaminated and potentially hazardous groundwater to
remain beneath the building.
National Britannia Limited_________________________________________________________________________
10
Option 4: Whole site protection.
The option would be to provide a boundary barrier to the whole site and build within this. Any
barrier, of suitable engineered quality to prevent ingress of free product and heavily polluted
groundwater and hydrocarbon vapours, would penetrate to a depth that would guarantee that
no free phase, floating on the surface of the groundwater, could enter the site under any
circumstances. It is probably preferable to avoid any differential water pressure on each side
of a barrier, allowing flow of deeper groundwater under or through the lower part of the
barrier.
It would be necessary to decide whether to replace all permeable soil within the site with low
permeability material.
Any building built within the protected area, with or without a basement would require to be
protected from any unforeseen entry of pollution, by means of a constructed vapour
protection system and passive venting from beneath this.
The option to be adopted, or a variation on an option, requires to be fully investigated and
designed by appropriate professionals and fully agreed with Planning officers and the
Environment Agency prior to any development being started. National Britannia Limited
does not warrant or advise that these constitute the only available options, that the
descriptions would fully suit the purpose of protection or that statutory authorities will agree
with the effectiveness of the options. Each option will need to be evaluated by the client, with
suitable professional assistance, in satisfying himself that the measures are effective and
also the cost of the measures.
10. CONCLUSIONS AND RECOMMENDATIONS
a). Sometime prior to 1999 the site of Barfords Chemicals became contaminated with
hydrocarbons, including xylenes and toluene. This material migrated on groundwater on
to the Fishing Smack Public House site.
b). Heavy and hazardous pollution of the groundwater persists beneath the site.
c). Under certain circumstances of high tide and heavy rain, contaminated groundwater has
entered the basement of the public house, generating potentially flammable or explosive
atmosphere in the basement, and may do so in the future.
d). London Borough of Barking and Dagenham Environmental Protection Team investigated
on at least three occasions and closed the public house under Emergency Action on one
occasion, because of the concentration of xylene vapour in the basement.
National Britannia Limited_________________________________________________________________________
11
e). Barfords Chemicals closed around 2003 and the public house closed in 2003.
f). The Barfords Chemicals site was remediated and a report produced by WSP, but this
remediation has not been adequately completed or closed out and problems persist at
the Fishing Smack Public House site.
g). There is no assurance that on removal of impermeable hardstanding and floors at the
former Barfords Chemicals site that further contaminant could not reach the groundwater
and migrate to the public house site.
h). With remediation of the adjoining site not having been taken to completion, there remains
a Major risk to human health (fire or explosion) at the Fishing Smack Public House site.
i). Testing of soil from the site indicates that no other significant contamination (other than
hydrocarbons on the groundwater and surrounding soil) exist on the Fishing Smack
Public House site.
j). This “Draft 2” Report offers four options for consideration. The option to be adopted, or a
variation on an option, requires to be fully investigated and designed by appropriate
professionals and fully agreed with Planning officers and the Environment Agency prior to
any development being started.

Result Notes
(1) Report for GC/MS Scan
The main compounds tentatively identified by library matching and
quantified ONLY by comparison with an internal standard are listed below.
Reporting criteria :-
The anticipated detection limit for this analysis is approximately 1000mg/l
That means that under the analytical conditions employed,
only compounds at concentrations greater than 1000mg/l are reported.
A tentative identification of a compound is only reported if the
PBM (Probability Based Matching) algorithm produces a match quality of
greater than 75%
Tentatively identified compounds :-
Sample mainly consisted of BTEX and other aromatics and aliphatic hydrocarbon material between C7 and C14.
Quantitation of this material unsuitable by this analysis.
See VOC and TPH results for best quantitation of these compounds
