An environmental site assessment (ESA) was undertaken at the Glenelg Dry Cleaners (GDC) site at 37 - 41Cliff Street, Glenelg East. The primary aim of the investigation was to identify areas of likely soil andgroundwater contamination resulting from either current or former activities at the site, using both targeted andgrid-based investigation locations.

The site is currently operationing as a dry cleaning operation, which is consistent with site dry cleaningactivities for approximately 50 years.

The investigations included advancing 8 soil boreholes across the site and laboratory analysis of selected soilsamples for chemicals of interest. Four groundwater wells were also installed at the site. The wells weregauged, purged and sampled on 7 October.

The chemicals of interest analysed by the laboratory include metals, petroleum hydrocarbons, monocyclicaromatic hydrocarbons, poly aromatic hydrocarbons, organochlorine pesticides and chlorinated hydrocarboncompounds (consistent with dry cleaning operations). Selected samples were also analysed for a wide rangeof inorganic and organic compounds typically referred to as a Victorian EPA screen.

The results of investigation identified:

Shallow fill overlying silty sands and sandy clay natural soils

Concentrations of PCE between 1.5 mg/kg and 9 mg/kg were reported in the upper soils (0 to 0.7 mdepth) at below the existing dry cleaning operations building, southern boundary storage area andformer spirit store.

Detectable soil petroleum hydrocarbon concentrations at the location of GW2 and SB2. Thehydrocarbon concentrations were below the assessment criteria and concentrations in sampleGW2/4 appeared associated with detectable groundwater hydrocarbon concentrations at GW2.

Groundwater standing water level was measured between 3.6 m and 4.1 m below ground surface.

Concentrations of filterable metals were low and generally below the EPP Water Quality Criteria(2003).

Petroleum hydrocarbon impacts to groundwater were identified in the four wells at the site. Theconcentrations of the hydrocarbons exceed the adopted criteria in GW1, GW2 and GW4.

VOCs impacts to groundwater were encountered in the four wells at the site. These included cis-1,2-DCE, TCE and PCE.

DRAF

T

Concentrations of cis-1,2-DCE and TCE in GW4 are one order of magnitude above the assessmentcriteria, with trace levels (below the criteria) also reported in GW2.

Detectable PCE concentrations were measured in the four wells at the site. The concentration ofPCE exceeds the EPP potable water criteria in wells GW1, GW3 and GW4 by up to 100 times thecriteria.

The PCE concentrations of 5.3 mg/L (GW1) and 5.5 mg/L (GW4) occur within 5 m of the western siteboundary and given the inferred north westerly groundwater flow direction, there is potential forgroundwater PCE concentrations above the EPP potable water criteria to occur off site below theadjacent residential properties.

The extent and nature of the PCE groundwater concentrations source are currently unknown.

R

The current density of investigation locations is considered insufficient to allow the assessment of the sitecontamination to a level that would be accepted by an environmental auditor in accordance with therequirements of the SA EPA. Therefore, should development of the site be a desirable objective, then werecommend an environmental auditor be appointed for the site to review the existing data and identify furtherinvestigation requirements.

Additionally due to the identified PCE groundwater concentrations, in accordance with the South AustraliaEnvironment Protection Act 1993, it is recommended that the SA EPA be notified of the groundwater impactas soon as practicable.

A Phase 1 ESA (site history) was completed for the site by Koukourou Engineers in November 2002. The sitehistory confirmed that the site has been an operational dry cleaners since the early 1950’s and prior to this theland was used for broad acre farming.

For further site history information please refer to

“Environmental Site History Report”, Koukourou Engineers, dated 14 November 2002, (Ref # Z70958-1)

A site inspection was undertaken on 15 September 2004. The site is rectangular in shape and is currently anoperational dry cleaners. The site topography is generally flat.

The dry cleaning operations are undertaken in a large stone building on the centre of the site. The boilers and surplus equipment are stored in sheds along the eastern boundary of the site, with an operational aboveground diesel storage tank (AST) located between the sheds. The ruins of the former spirit store are locatedin the south western corner of the site with a concrete paved general storage area along the southernboundary. A former shade house area is located along the western boundary with a garage on the northwestern corner of the site.

Two disused underground storage tanks (UST) are located on the site, one adjacent the eastern boundary to the south of the storage sheds and one on the south western corner of the site adjacent the former spirit store.The eastern UST was dipped during the field investigations and appeared to be a 1,000 gallon (4,500 litres)tank with approximately 50 gallons (250 litres) of diesel type fuel remaining in the tank. The condition of thesouth western UST is not known, but its fill point appeared to be sealed with concrete.

The site and features are shown in Figure 1.

R

The Soils Association Mapsheet of the Adelaide Region (1989) indicates the site is underlain by Red BrownEarths consisting of mottled silty clay over brown silty clay with granular structure, slight lime, becoming sandywith depth. The Pooraka Formation underlies the red brown earths at depth.

The Department of Water, Land and Biodiversity Conservation (DWLBC) groundwater database indicates thestanding water level below the site is between 3 and 7 m with a Total Dissolved Solids (TDS) of between 400 mg/L and 3,000 mg/L.

The field investigation and sampling works were undertaken by an environmental engineer between22 September 2004 and 7 October 2004.

An assessment of both soil and groundwater was undertaken in accordance with the National EnvironmentProtection (Assessment of Site Contamination) Measure (NEPM, 1999). The site assessment was alsoundertaken in general accordance with the following guideline documents:

Australian Standard AS 4482.1 “Guide to the sampling and investigation of potentially contaminatedsoil - Part 1: Non-volatile and semi-volatile compounds”, 1997.

Australian Standard AS 4482.2 “Guide to the sampling and investigation of potentially contaminatedsoil - Part 1: Volatile substances”, 1999.

Australian / New Zealand Standard AS/NZS 5667.11 “Water quality – Sampling, Part 11: Guidanceon sampling of groundwaters” 1998.

The sampling methodologies for soil and groundwater are outlined in the following sections.

R

The primary aim of the investigation was to identify any potential soil and groundwater contamination issuesresulting from either current or former activities on the site. Therefore, the soil bores were generally targetedto potential contamination sources across the site. In addition a number of bores were placed on a gridbased pattern around the site features and targeted bores. The investigation locations included:

Soil bores SB1 and SB2 were placed adjacent the former and current boiler sheds and AST;

Soil bore SB3 was located in the former shade house area on the western boundary of the site;

Soil bore SB4 was located through the centre of the concrete storage area on the southernboundary;

Soil bores SB5, SB6, SB7 and SB8 were located on a grid based pattern within the dry cleaningoperations main building;

Groundwater wells GW1 and GW2 were targeted to the existing disused USTs;

Groundwater wells GW3 and GW4 were located on the northern and western boundaries inferreddown hydraulic gradient of the site operations;


DRAF

T

The following scope of soil investigations was undertaken:

All investigation locations were cleared for underground services using an independent cable locator(BRP Products);

A total of 8 soil bores were drilled to a maximum depth of 4 m (but on average around 2 m) usingpush tube techniques. The location of the soil bores are discussed in the previous section and areshown on Figure 2;

The soil cores were placed in plastic trays for logging and sampling. The trays and drillingequipment were decontaminated between investigation locations using a high pressure cleaner;

The materials encountered in the soil cores were logged (refer Appendices) and selected soilsamples were retrieved from the units of fill and the underlying natural soils for laboratory analyses.The samples were screened for potential volatile contaminants using a photoionisation detector (PID)in the field;

Following completion of logging and sampling, the soil bores were backfilled using the spoil fromeach bore;

The samples were transported in a chilled cool box to the laboratory for selected chemical analysisunder chain of custody (COC) documentation.

The following scope of groundwater investigations was undertaken:

Well permits were obtained from the Department for Land Water and Biodiversity Conservation(DLWBC) prior to the installation of wells.

Four groundwater monitoring wells (GW1 – GW4) were installed into the shallow unconfined aquiferat the site. Wells GW1 and GW2 were advanced with push tube techniques with soil samplesrecovered for possible laboratory analysis, prior to groundwater well installation with solid augertechniques. Wells GW3 and GW4 were installed with solid auger techniques only and no soilsamples were recovered from these locations;

The wells were constructed using Class 18 uPVC with a 3 m machine slotted screen and casing.The annulus between the PVC and the hole was backfilled with washed 8/16” sand to at least 0.5 mabove the slotted screen. Care was taken to ensure that the slotted screen straddled the standingwater level, to allow the assessment of any phase separate hydrocarbons. At least a 0.5 m thickbentonite plug was placed above the sand, and the holes were completed with cement / bentonitegrout and flush mounted gatic covers;

The gauging of standing water level and separate phase hydrocarbons (if any) were measured ineach well using an electronic interface probe;

4.1 Soils

4.1.1 Soil / Fill Materials Encountered

The soil borehole reports SB1 – SB8 and groundwater monitoring wells GW01 – GW04 are included in Appendix B.

The materials encountered in the soil bores generally consisted of gravely sand surface fill up to 0.4 m deep over the majority of the site. This fill was underlain by brown silty sands of generally between 0.4 m and 1.2 m thick, with brown to red brown sandy clays extending to greater than 6 m depth below. Refusal was encountered at SB8 due to > 0.4 m of concrete foundations at two locations.

4.1.2 Potential Volatile Contaminants

Selected replicate soil samples were screened for ionisable compounds using a photoionisation detector (PID). The results of the PID screening are presented in the borelogs included in Appendix B. The PID results were generally below 50 ppm indicating the likelihood of elevated volatile contaminants is low. However, elevated PID results were measured in samples GW1/1, GW1/3, GW2/4, SB5/1, SB5/2 SB5/4, BS6/1 and SB6/3, between 50 ppm and 192 ppm indicating the possible presence of elevated volatile contaminants at these locations.

4.1.3 Soil Analytical Results

A summary of the laboratory results for soils are presented in Table A1 appended to this report. Laboratory Certificates are included as Appendix A. A summary of the laboratory results is presented below and in Figure 3.

Petroleum Hydrocarbons

Concentrations of petroleum hydrocarbons were reported below the laboratory reporting limits for sample analysed with the exception of:

300 mg/kg in sample GW2/4 – (3.8 – 4.0 m depth over the SWL), adjacent the disused UST in the south eastern section of the site. It is noted that concentrations of petroleum hydrocarbons were below the reporting limits at 2.5 – 2.6 m depth (unsaturated zone, sample GW2/3) at this location.

35 mg/kg in sample SB2/4 – (2.6 - 2.7 m depth) adjacent the operational AST and boiler room on the eastern boundary of the site. It is noted that no hydrocarbon concentrations were reported at 0.3-0.4 m depth (sample SB2/1) and no deeper soil samples were analysed at this location.

These concentrations of hydrocarbons are low and below the NSW EPA sensitive land use adopted guidelines.

The following assessment guidelines were used in the interpretation of the laboratory results. The guidelinesare presented with the laboratory results in the Tables appended to this report.

The laboratory results were compared to the following guidelines:

R

The National Environment Protection (Assessment of Site Contamination) Measure, 1999, Health BasedInvestigation Levels (HILs) were used to assess the potential risks to human health, for a sensitive land use(Setting A), including standard residential.

The HILs are based on generally conservative assumptions for the estimated exposure of residents / workersin the above land use scenarios. In the first instance the NEPM Setting A investigation levels were comparedagainst as they are the most sensitive health based guidelines. The NEPM states that:

“An investigation level is the concentration of a contaminant above which further appropriateinvestigation and evaluation will be required (ANZECC/NHMRC Guidelines 1992)”.

An exceedence of an investigation level does not indicate that there is a definite risk to human health, butrather that further site-specific assessment is undertaken to quantify the potential risk to human health.

The NSW EPA Guidelines for the assessment of service station sites were used as a supplement whereguideline values were not provided in the NEPM for volatile and semi-volatile contaminants. These guidelinesprovide threshold values to which a former service station site should be remediated to if it has been proposedfor a sensitive land use. The guideline values presented are primarily based on considerations of human andecological health. Lower concentrations are presented in the NSW EPA guidelines and refer to the protectionof terrestrial organisms in soil.

R

The NEPM Ecological Intervention Levels (EILs) - Interim Urban were used to assess the potential risks to the environment.

The EILs Interim Urban aim to protect ecological values (eg. flora, fauna) in developed areas. The EILs arebased on considerations of phytotoxicity (copper, chromium, lead) and soil survey data (barium, phosphorous,sulfur) from four Australian capital cities. The ANZECC B values were retained for the other contaminants.

Groundwater in South Australia is assessed in accordance with the recently issued ‘Environment Protection(Water Quality) Policy, 2003. The policy covers all waters in the State including marine, estuarine and inland(surface and underground) waters.


DRAF

T

The steps involved in setting the water quality objectives entail:

1. setting the environmental values that are required to be protected

2. determining water quality characteristics that are important for these values

3. setting criteria for each characteristic that adequately protect each environmental value

4. choosing the most stringent set of criteria for the environmental values applicable to each waterbody.

In line with the National Water Quality Management Strategy, the policy recognises that the protectedenvironmental values or uses are:

Aquatic ecosystem (fresh waters and marine waters)

Potable use

Recreation and aesthetics (primary contact, secondary contact and aesthetics)

Agriculture/aquaculture (including irrigation, livestock)

Industrial use

Groundwater X X X X X X X X

The criteria for the environmental values are presented compared against the laboratory results in Table A2(appended) for potable and irrigation uses.

It is noted that the water quality criteria presented in Schedule 2 of the EPP do not contain criteria for total petroleum hydrocarbons or trichloroethene (TCE). In the absence of TPH guidelines, the EnvironmentalQuality Objectives in Netherlands (Dutch, 1994) criteria were adopted. The Dutch 1994 guidelines provideintervention levels that indicate a level of contamination which seriously diminishes the functional properties ofthe groundwater for humans, flora or fauna, or at which the functional properties of the groundwater are atserious risk of being diminished and target values for groundwater hydrocarbon concentrations.

In the absence of TCE criteria the World Health Organisations (WHO) potable water criteria of 0.04 mg/L andthe Australian and New Zealand Environment and Conservation Council (ANZECC) Australian Water QualityGuidelines for Fresh and Marine Waters – Primary Recreational Contact of 0.03 mg/L were adopted.

The concentrations of PAHs, OCPs, cresols and phenols were below the reporting limits in samples tested.

The concentrations of chlorinated hydrocarbons (CHC) and volatile organic compounds (VOCs) were belowthe laboratory reporting limits with the exception of tetrachloroethene. Tetrachloroethene is commonly knownas perchloroethylene (PCE) which is a common dry cleaning solvent. The maximum concentration of PCEwas measured in soil sample SB7/1 (0.1-0.3 m depth) of 9 mg/kg. PCE was also measured at 1.5 mg/kg inGW1/4, 4.7 mg/kg in SB4/1, 3.8 mg/kg in SB5/1, 3.3 mg/kg in SB5/2 and 4.5 mg/kg in SB6/1.

The concentrations of PCE observed were only in the upper 0.7 m of soils below the dry cleaning operationsmain building and along the southern site boundary near the former spirit house and chemical storage areas.Concentrations of PCE below 1 m depth at the locations of SB6 and SB5 were below the laboratory reportinglimits.

It is noted that no investigation levels for PCE in soils are provided in the NEPM.

The concentrations of heavy metals and cyanide are below the NEPM Setting A, standard residential andecological investigation levels.

The standing water level (SWL) of the wells was measured on 30 September and 7 October 2004. The SWL’s were reduced to an arbitrary datum to allow an assessment of the groundwater flow direction at the site. The reduced levels are presented in Table 4.

Recorded values for pH were neutral, whilst conductivity values ranged from 4.10 mS/cm in GW4 to4.40 mS/cm in GW3, which approximates to a total dissolved solids measurement of between 2,250 mg/L to2,450 mg/L.

Redox values were measured between 9 mV and 159 mV, which indicate a neutral or slightly oxidisingenvironment.

A hydrocarbon type sheen and odour was observed on the groundwater during purging from GW2.

Tetrachloroethene (PCE) at 5.5 mg/L in GW1, 0.013 mg/L in GW2, 0.16 mg/L in GW3 and 5.3 mg/Lin GW4. The concentrations in GW1, GW3 and GW4 exceed the EPP potable water criteria of 0.04mg/L.

Trichloroethene (TCE) at 0.002 mg/L in GW02 and 0.058 mg/L in GW4. The concentration in GW4exceeds the adopted WHO potable water criteria of 0.04 mg/L and ANZECC primary contact,recreation guideline of 0.04 mg/L in the absence of EPP criteria.

Concentrations of petroleum hydrocarbons were measured in groundwater samples GW1, GW2, GW3 andGW4 between 0.02 mg/L and 1.9 mg/L. The concentrations of hydrocarbons exceeding the adopted Dutchtarget value of 0.05 mg/L were measured in samples from GW1, GW2 and GW4. The petroleum hydrocarbonconcentrations consisted of predominantly C6-C9 fraction hydrocarbons in GW1 and GW4, likely to beassociated with solvents used on the site, while GW2 was dominantly C15-C28 fraction hydrocarbons.

It is noted that BTEX concentrations in wells was below the laboratory reporting limits.

Concentrations of filterable metals were low and were generally below the EPP Water Quality Criteria (2003),with the exception of boron in GW2 and GW3 and manganese in GW2.

The pH of groundwater from wells GW2 and GW4 was reported as 6.8 pH units by the laboratory, which isconsistent with the field data indicating neutral groundwater.

To ensure that results were not biased by field sampling techniques and intra-laboratory variation, soil andgroundwater blind field duplicate samples were collected in the field for selected analyses. In addition, arinsate blank was also collected.

The relative percentage difference (RPD) was calculated on these duplicate pairs. The RPD is defined as thedifference between the duplicate samples as a percentage of the mean. The RPD is not calculated whereone or both of the duplicate results are below the laboratory reporting limits. The RPDs are included in thetabulated results.

F D

Three soil blind duplicate samples (D1 dup of SB2/2, D2 dup of SB5/1 and D3 dup of GW2/4) were analysedfor metals, TPH, BTEX and CHCs. One water blind duplicate sample (D1 dup of GW01) was collected andanlaysed for metals, TPH, BTEX and CHCs. The RPD results for these duplicate samples are presented inthe following table.

The RPDs calculated for field duplicate samples ranged from 0% to 156 %, with six of the twenty six RPDsgreater than the accepted maximum of 50%.

The elevated groundwater sample RPDs are associated with low concentrations of arsenic and C10-C14

fraction hydrocarbons in duplicate D1 and GW04. The elevated soil RPD’s are associated with primary andduplicate sample low metal concentrations that are consistently below the NEPM EIL’s.

Based on the duplicate sample RPDs the analytical methods and sampling techniques are considered toproduce representative results.

4.3.2 Rinsate Blank

A rinsate blank sample was collected by running demineralised water through a washed pushtube afterdecontamination. A summary of the laboratory results is presented in Table A3.

The rinsate was analysed for metals. The results were less than the laboratory reporting limits, with theexception of zinc (4.7 mg/L). No elevated zinc concentrations above the NEPM investigation levels werereported indicating the high rinsate sample zinc concentration may be an anomaly. Based on the poorcorrelation between the investigation and rinsate sample result and low metals concentrations it is consideredunlikely that the sampling equipment contributed to any significant risk of cross-contamination between thesampling locations.

4.3.3 Internal Laboratory QA

The laboratory undertook internal QA/QC procedures, which are within the acceptable limits of repeatability,chemical extraction and detection. The chemical results are therefore considered to represent theconcentrations of chemicals in samples provided to the laboratory.

4.3.4 Summary of QA

The field duplicate samples and internal laboratory QA show a good correlation, indicating that the samplingand laboratory methods are appropriate, and the results are representative of the samples provided to thelaboratory.

5. SUMMARY

Soils

Based on the limited testing undertaken to date, the results of laboratory soil testing reported elevatedconcentrations of PCE only. The elevated concentrations of PCE were reported in the upper 0.7 m of soilsbelow the existing dry cleaning operations building and on the southern section of the site adjacent the formerspirit store and storage areas. PCE is a common dry cleaning solvent and it is considered that the drycleaning operations are the likely source of the PCE contaminated soils. Although no PCE concentrations insoils were reported below 0.7 m, elevated PCE concentrations measured in groundwater would suggest adeeper soil source.

The vertical and lateral extent of the PCE concentrations in soils along the western and south easternboundaries is unknown as no PCE analysis was conducted at these locations.

No PCE was detected in samples adjacent the former boiler room on the eastern boundary.

Concentrations of petroleum hydrocarbons in soils are low. The concentrations at the location of GW2, appear to be associated with impacted groundwater. No staining or odours were observed in soils within theunsaturated zone adjacent to the disused USTs.

Groundwater

Concentrations of filterable metals were low and generally below the EPP Water Quality Criteria (2003), with the exception of boron and manganese. Given that no groundwater extraction occurs at the site and thatthere are no identified sources of boron or manganese, these exceedences are not considered to present a asignificant risk.

Petroleum hydrocarbon impacts to groundwater were identified in the four wells at the site. Theconcentrations of the hydrocarbons exceed the adopted criteria in GW1, GW2 and GW4. The petroleumhydrocarbon concentrations consisted of dominantly C6-C9 fraction hydrocarbons in GW1 and GW4. It isnoted that BTEX concentrations were below the laboratory reporting limits and elevated VOCs weremeasured in these samples, therefore the C6-C9 fraction hydrocarbon result may represent elevated levels ofother non-petroleum hydrocarbon VOCs such as white spirits or solvents.

The petroleum hydrocarbon composition of GW2 was predominantly C15-C28 fraction hydrocarbons, which isconsistent with a diesel or light fuel oil source, and may be associated with historic storage of diesel or lightfuel oil at the site for boiler operation.

VOC impacts to groundwater were encountered in the four wells at the site. Concentrations of cis-1,2 DCEand TCE were measured in GW4 one order of magnitude above the assessment criteria, with trace levels,below the criteria, also reported in GW2. Cis-1,2 dichloroethene and TCE are daughter products of thebreakdown of PCE.

PCE was measured in all four wells at the site. The concentration of PCE exceeds the EPP potable watercriteria in wells GW1, GW3 and GW4 at up to 100 times the criteria. The PCE concentrations of 5.3 mg/L


DRAF

T

(GW1) and 5.5 mg/L (GW4) occur within 5 m of the western site boundary and given the inferred northwesterly groundwater flow direction there is potential for groundwater PCE concentrations above the EPPpotable water criteria to occur off site below the adjacent residential properties. The source of thegroundwater PCE concentrations is currently unknown.

6. CONCLUSIONS

An environmental site assessment was undertaken at the Glenelg Dry Cleaning site at 37 - 41 Cliff Street,Glenelg East. It is understood that GDC wish to assess the potential environmental liabilities associated withthe site for possible site redevelopment or divestment.

The primary aim of the investigation was to identify areas of likely soil and groundwater contaminationresulting from either current or former activities at the site, using both targeted and grid-based investigationlocations.

The results of investigation identified:

Shallow fill overlying silty sands and sandy clay natural soils

Concentrations of PCE between 1.5 mg/kg and 9 mg/kg were reported in the upper soils (0 to 0.7 mdepth) at below the existing dry cleaning operations building, southern boundary storage area andformer spirit store.

Detectable soil petroleum hydrocarbon concentrations at the location of GW2 and SB2. Thehydrocarbon concentrations were below the assessment criteria and concentrations in sampleGW2/4 appeared associated with detectable groundwater hydrocarbon concentrations at GW2.

Groundwater

Groundwater standing water level was measured between 3.6 m and 4.1 m below ground surface.

Concentrations of filterable metals were low and generally below the EPP Water Quality Criteria(2003).

Petroleum hydrocarbon impacts to groundwater were identified in the four wells at the site. Theconcentrations of the hydrocarbons exceed the adopted criteria in GW1, GW2 and GW4.

VOCs impacts to groundwater were encountered in the four wells at the site. These included cis-1,2-DCE, TCE and PCE.

Concentrations of cis-1,2-DCE and TCE in GW4 are one order of magnitude above the assessmentcriteria, with trace levels (below the criteria) also reported in GW2.

Detectable PCE concentrations were measured in all four wells at the site. The concentration ofPCE exceeds the EPP potable water criteria in wells GW1, GW3 and GW4 by up to 100 times thecriteria.

The PCE concentrations of 5.3 mg/L (GW1) and 5.5 mg/L (GW4) occur within 5 m of the western siteboundary and given the inferred north westerly groundwater flow direction, there is potential for groundwater PCE concentrations above the EPP potable water criteria to occur off site below the adjacent residential properties.

The extent and nature of the PCE groundwater concentrations source are currently unknown.


DRAF

T

7. RECOMMENDATIONS

The current density of investigation locations is considered insufficient to allow the assessment of the sitecontamination to a level that would be accepted by an environmental auditor in accordance with therequirements of the SA EPA. Therefore, should development of the site be a desirable objective, werecommend that an environmental auditor be appointed for the site to review the existing data and identifyfurther investigation requirements.

Additionally due to the identified PCE groundwater concentrations, in accordance with the South AustraliaEnvironment Protection Act 1993, it is recommended that the SA EPA be notified of the groundwater impactas soon as practicable.
