Executive SummaryCoffey has carried out an additional contamination assessment for ARUP on behalf of the Roads and Maritime Service (Roads and Maritime) for four sites proposed for land acquisition as part of the 1.3km Mulgoa Road Stage 1 Upgrade between Jeanette Street and Blaikie Road. The sites selected by Roads and Maritime for assessment were:

• 124-126 Mulgoa Road (BP Service Station)• 221 Worsley Street (Shell/Coles Express Service Station)• 283-287 Mulgoa Road (Western Motorcycles)

• Intersection of M4 Motorway and Mulgoa Road (M4 Embankments)

The objective of the assessment was to investigate whether there was the potential for contaminants of concern (CoC) posing unacceptable risks to human health or the environment at each of the four nominated locations and in light of the proposed future land use as a roadway.

It was not the objective of the assessment to carry-out a preliminary waste classification and was also limited to shallow soil sampling due to the agreed sampling methodologies (ie hand auger). Additionally, sampling was limited to accessible areas only with areas beneath driveways not being assessed.

Coffey undertook a review of previous contamination reports and carrried out a shallow soil sampling across each of the four sites. Soil samples collected from the 25 hand-augured boreholes were analysed for potential contaminants of concern along with soil vapour collected from individual temporary vapour implants installed at each service station site.

All results (soils and soil vapour) reported concentrations of contaminants of potential concern (CoPC) below laboratory practical quantitication limits and/or below adopted human health and ecological screening criteria except for two locations. Boreholes BH12 and BH13 collecetd from the Shell/Coles Express Service Station site reported exceedences of the total recoverable hydrocarbon (TRH C16- C34) ecological screening levels for public open space. The origin of the TRH C16-C34 was suspected to be the result of surface spillage given the depth of samples collected. It was concluded that if the design of the roadway in this area comprises hardstand the risk to ecological communities is considered to be acceptable risk and low as the ecological value beneath the hardstand material is low.

No asbestos containing material was observed or reported by the laboratory for the samples collected. During the construction of the road upgrade, it is recommended that a unexpected finds protocol is implemented.

Groundwater was not assessed a part of this investigation. Should construction work for the roadway require excavation to depths of greater than 6 mbgl (ie the expected depth of groundwater), groundwater assessment may be required. Groundwater flow direction from the BP Service Station site is expected to be towards the Nepean River located to the west. As such, groundwater may be hydrocarbon impacted as the acquisition area is located hydraulically downgradient from UST infrastructure. However, results from the soil vapour sampling conducted at BH1/SV1 indicates a low potential for presence of hydrocarbon within soil vapour.

Mulgoa Road Stage 1 Road Upgrade – Additional Contamination Assessment

IntroductionARUP Pty Ltd (ARUP) engaged Coffey Services Australia Pty Ltd (Coffey), on behalf of Roads and Maritime Services (Roads and Maritime) to undertake an additional contamination assessment at portions of four (4) sites (herein referred to as “the sites”) proposed for acquisition/development as part of the 1.3km Mulgoa Road Stage 1 Upgrade between Jeanette Street and Blaikie Road (herein referred to as “the Project”).

1.1. BackgroundCoffey previously undertook a Phase 1 desktop study of a wider area (including future stages of the wider Mulgoa/Castlereagh Road Corridor Upgrade) in May 2016 (Coffey 2016)1 to assess the likelihood for contamination within the proposed project area due to historic or current activities and to provide recommendations with respect to managing identified issues during construction. The Phase 1 report focused on identifying constraints on proposed construction activities with respect to contamination and was not intended to assess acquisition related risks.

Within the Stage 1 Upgrade, it is understood there are currently up to 21 properties (7 commercialand 14 residential) (or portions of) which are proposed for acquisition. The majority of these propertiesare subject to partial acquisitions.

The purpose of this contamination assessment was to inform the land acquisition process for the Project. ARUP, on behalf of Roads and Maritime, requested Coffey to undertake additional assessment at portions of the sites identified in Table A which comprised three partial property acquisitions and the M4 embankments of the M4 Motorway road bridges. The location of the sites assessed are illustrated in Figures 1 to 4 (Appendix A).

1.2. ObjectiveThe objectives of the assessment was to investigate whether there was the potential for contaminants of concern (CoC) to pose an unacceptable risk to human health or the environment at the four nominated locations and in light of the proposed future land use as a roadway.

It was not the objective of the assessment to carry-out a preliminary waste classification and was also limited to shallow soil sampling due to the agreed sampling methodologies (ie hand auger). Additionally, sampling was limited to accessible areas only with areas beneath driveways not being assessed.

Scope of WorkCoffey carried out the following scope of work:

• Review previous environmental reports

• Collection of soil samples and carry out field screening at 25 boreholes using a hand auger• Installation of a temporary (x1) soil vapour implant at each of the Shell/Coles Express and BP

Service Station sites• Analysis of soil and soil vapour samples at a lab for CoPC using NATA accredited methods• Compare the results from soil and soil vapour sampling against adopted human health and

ecological screening criteria• Provision of a combined contamination assessment report for the four sites to assess potential

risks to human health and provide any recommendations

3. Regulatory FrameworkThis additional contamination assessment was carried out with consideration to the following legislation, guidelines and regulations:

• NSW Work Health and Safety Act 2011 (WHS Act 2011)

• NSW Work Health and Safety Regulation 2017 (WHS Regulation 2017)• Contaminated Land Management (CLM) Act, 1997 (CLM Act 1997)• Contaminated Land Management Amendment Act 2008

• Protection of the Environment Operations (POEO) Act 1997 (POEO Act 1997)• National Environment Protection Council (NEPC) Act 1994 (NEPC Act 1994)• National Environment Protection Council, National Environment Protection (Assessment of Site

Contamination) Measure, 1999 (April 2013) (amended ASC NEPM)• CRC Care Technical Report No. 10, Health Screening Levels for Petroleum Hydrocarbons in Soil

and Groundwater, 2011 (CRCCARE 2011)• CRC Care. Technical Report No. 23. Petroleum hydrocarbon vapour intrusion assessment:

Australian guidance, 2013 (CRCCARE 2013)

• NSW Office of Environment and Heritage (OEH), Guidelines for Consultants Reporting onContaminated Sites, 2011 (OEH 2011)



• Standard Australia AS4482.1, Guide to Investigation and Sampling of Sites with PotentiallyContaminated Soil, Part 1: Non-volatile and Semi-volatile Compounds, 2005 (AS4482.1 – 2005)

• Standards Australia AS4482.2, Guide to the Sampling and Investigation of PotentiallyContaminated Soil, Part 2: Volatile Substances, 1999 (AS4482.2-1999).

Data Quality ObjectivesThe data quality objectives (DQOs) adopted the AS4482.1-2005 approach which are referenced in the amended ASC NEPM. The DQOs cover seven iterative steps which specify the parameters for the assessment in terms of number of samples, type of samples to be collected and identify appropriate sampling methods required to assess the CoPC. Appendix C describes in detail the DQO process adopted for this assessment.

Previous Contaminated Land ReportsCoffey has reviewed the previously prepared Phase 1 Contamination Assessment Report (Coffey 2016)Error! Bookmark not defined. for the proposed Mulgoa Road/Castlereagh Road corridor (“the study area”) with the key points relevant to the Project area summarised below.

The objectives of the Phase 1 contamination assessment were to:• Conduct a Phase 1 preliminary contamination assessment to assess the likelihood for

contamination to exist within the study area from past or present activities.• Provide recommendations with respect to managing identified potential contamination issues

within the study area.

The scope of works included a review published information and previous reports, and undertaking a site walkover to observe potential sources of contamination and identify sensitive land uses.

Site history information indicated that the study area was generally rural / low density residential until the 1960’s/1970’s. Following this, residential and commercial development increased along the Mulgoa Road portion of the route from the 1970’s on-wards. Recent development (i.e. post 2000) was described as generally comprising commercial retail and restaurants. Broadly, contamination is likely to be attributed to one of the following sources:

1. Former and current fuel stations, due to the storage of petroleum hydrocarbons and vehicleworkshop activities.

2. Fill mounds of unknown quality and origin along selected street frontages.3. Vehicle workshops due to storage and usage of hydrocarbons and lubricants, as well as handling

of potentially hazardous materials (e.g. such as asbestos lined brake pads). These workshopsare either standalone, or part of car sales yards or service stations.

4. Other more diffuse and generally lower risk sources, such as weathering of hazardous materialsfrom older buildings (e.g. lead based paints and asbestos sheeting), electrical transformer boxesdue to localised storage of hazardous chemicals (e.g. within transformer boxes), and the potentialfor asbestos pipework within older underground service pits and cables.

Embankments beneath M4 Motorway

The BP site area comprised a garden bed approximately 3m x 25m containing small shrubs and mulch. A diesel bowser was located at the south-western corner adjacent to BH4. Some minor staining of the concrete plinth beneath the diesel bowser was observed.

The Shell/Coles Express site area assessed was approximately rectangular in shape and comprised largely open space and was sparsely covered with grass. Some tall trees were also present. No staining was observed on the surface. The site was intersected by two driveways servicing the service station site from Mulgoa Road. No underground petroleum storage systems (UPSS) were observed within the site area.

The site assessed was approximately rectangular in shape (13m x 40m). The ground surface was largely grassed with a driveway located to the north of the site. Numerous motorcycles were lined up on display across the front of the building and on the site area. No staining was observed on the grass surface.

The embankment area assessed comprised a number of sections surrounding the abutments of the M4 Mulgoa Road overpass. Large portions of the site were overgrown with tall shrubs and grasses. An open stormwater drain was located along the western side of the M4 and numerous litter was observed across the site. A small fibre cement pipe was identified at the base of an embankment area, of which a sample was collected and subsequently submitted for asbestos analysis, which was confirmed by the laboratory as not containing asbestos (refer to Section 10).

6.3. TopographyA review of the 1:100,000 Penrith topographical map (Central Mapping Authority, 1985) indicates that the sites are relatively flat and lies at an approximate elevation of 30 mAHD. Apart from the M4 embankments, all sites were relatively flat.

6.4. Hydrology and DrainageThe sites are situated within the Nepean River catchment area, and the river runs almost parallel to the Project area. No tributaries were observed to flow within the Project area. Surveyors Creek is located approximately 200m to the northeast of the BP Service Station and is outside of the Project area but likely to receive surface flows arising from this Project area. Surveyors Creek also appears to be culverted.

The existing roadway is generally elevated above surrounding land, and is contains kerb and guttering with stormwater drains likely distributing surface flows into the Council stormwater system. Regionally, drainage is likely to flow towards the tributaries, or west towards the Nepean River.

6.5. Acid Sulfate Soil and Salinity PotentialAcid sulfate soil (ASS) is typically associated with sedimentary soils deposited under coastal processes, none of which are within the proposed route area. Acid sulfate soil risk mapping, produced by NSW Department of Primary Industries, does not extend this far from the coast. Acid sulfate soils are predominantly situated at elevations of less than 5m AHD. As the sites are at an elevation of approximately 30m AHD, it is considered unlikely to be actual or potential acid sulfate soils at the sites.

Reference to the Western Sydney salinity potential map (NSW Department of Infrastructure, Planning and Natural Resources, 2003) indicates the site is situated in an area classed as moderate salinity



potential. Scattered areas of scalding and indicator vegetation have been noted in these areas, but salinity concentrations are yet to be mapped; or may occur if risk factors change adversely.

An area either side of Surveyor’s creek to the north of the site is mapped as having a high salinity potential. These areas are typically defined as areas were soil, geological, topographical and hydrogeological conditions predispose a site to salinity. The saline areas are more likely to be present in drainage systems (e.g. floodplains) where water accumulation is high.

6.6. Local Geology and Soil LandscapeThe 1:100,000 Penrith Geological Series Sheet indicates each of the sites are underlain by gravel, silt, sand and clay alluvial deposits of the Cranebrook Formation deposited in the Quaternary period.

The Penrith 1:100,000 soil landscape series sheet 9130 (Soil Conservation Service of NSW, 1989), shows that each of the sites are situated within the Freemans Beach soil landscape. Freemans Beach is an active floodplain of the Nepean River, featuring a generally level topography with active relief (less than 10m) towards local backswamps and levees. Soils that could be present include deep alluvial soils, typically sands and brown loams, which may be apedal to moderately structured. This landscape is prone to high streambank erosion potential and frequent flooding.

6.7. Regional Hydrogeology and Groundwater UsageA search of the NSW Department of Natural Resources Groundwater Bore Register indicate there are no registered boreholes within the Project Area.

Multiple groundwater bores are located within 500m of the project area and are used for a range of purposes such as recreational use and as monitoring wells. Groundwater monitoring wells indicate groundwater levels are in the order of 6 mbgl to 9 mbgl. Available bore records are provided in Appendix H and summarised below:

• A cluster of monitoring wells (x4) are located at a 7-Eleven Service Station Site which is 400msouth-west of the Project area. No information is available for these wells but are assumed to beassociated with underground petroleum storage system (UPSS) monitoring.

• A test bore (status listed as inactive) is located within the Regentville Public School (bore IDGW108486) and is listed for recreational groundwater use. The bore is 200m deep and appearsto target sandstone fractures at a depth of approximately 190m. Standing water levels are listedat 50 mbgl and the bore is inactive.

• A cluster of monitoring wells (x4) is located at a former Caltex Service Station site located at 229Mulgoa Road and is approximately 300m north east of the Project Area. Bores are between 9mbgl and 12 mbgl with standing water level at between 8 mbgl to 9 mbgl. A

• A cluster of monitoring wells (x6) are also located at a Mobil Service Station site (7-Eleven)located 92 Mulgoa Road and approximately 360m north east of the Project Area. Bores arebetween 5 mbgl and 12 mbgl with standing water level at between 4.5 mbgl to 9 mbgl.

Based on the proposed target depth of this assessment, groundwater is not expected to be encountered during construction of the roadway. Any contaminated groundwater identified within theabove-mentioned bore records would not be expected to the Project area as groundwater flowdirection is expected to flow to the west towards the Nepean River.



Preliminary Conceptual Site ModelContamination identified within the project area, if not managed appropriately could pose a potential risk to human health and/or the environment during construction or ongoing future use as a roadway. For an environmental or human health risk from contamination to be present, there must be a plausible pollutant linkage between the source and a receptor by means of a transport mechanism (pathway).

7.1. Potential Contamination SourcesAs outlined in the Coffey Phase 1 Contamination Assessment (Coffey, 2016), the potential sources of contamination at each of the assessment sites are detailed below. No other potential sources of contamination were identified during this assessment.

• Hydrocarbon impacts from petroleum infrastructure at service station sites (BP and Shell/ColesExpress Service Station Sites)

• Degreasing solvents used at commercial facilities (ie Western Motorcycles)

• Potential impacted fill material of unknown origin (M4 Embankments)

7.2. Chemicals of Potential ConcernChemicals of potential concern (CoPC) for this assessment comprised:

• Total recoverable hydrocarbons (TRH)• Benzene, toluene, ethylbenzene, xylene and naphthalene (BTEXN) compounds• Polycyclic aromatic hydrocarbons (PAH)

• Organochlorine pesticides (OCP)• Polychlorinated biphenyls (PCB)• Heavy metals (arsenic, cadmium, chromium, copper, mercury, lead, nickel and zinc)• Volatile chlorinated hydrocarbons (VCH)

• Asbestos

7.3. Release Mechanisms and Migration PathwaysThe following activities could potentially disturb contamination, if present, during construction and operation as a roadway:

• Mechanical or manual excavation during construction and future maintenance work• Installation of footings

• Site clearing of vegetation• Handling, stockpiling and transporting material resources

• Interception (dewatering) of surface flows• Wind dispersion

Coffey754-SYDEN214564-R01 8


Conduits for migration of CoPC may be provided by more permeable layers within the fill and/or natural strata and/or underground services. Migration pathways for contamination may also include stormwater and sediment run-off from the construction area.

7.4. Receptors and Exposure RoutesThe following potential receptors were considered for this contamination assessment:

• Construction workers and future maintenance workers from direct contact, and inhalation of dust,asbestos fibres and vapours

• Adjacent site users from ingestion and inhalation of dust and asbestos fibres

• Future site users (i.e. public) from dermal contact, ingestion and inhalation of dust and asbestosfibres

• Aquatic freshwater ecosystems of the Nepean River and its tributaries

Fieldwork Methodology8.1. Sample RationaleThe rationale for sampling was to provide spatial coverage across the site areas in order to meet the minimum sampling frequency number as per NSW EPA Sampling Design Guidelines and provide a preliminary assessment of soil vapour at each of the service station sites. Soil vapour sampling was carried out at the service station sites to preliminary assess the potential for groundwater to be contaminated thus releasing vapours, as groundwater reports were not provided for review.

Sampling was limited in depth to less than 1m due to the limitations of the sampling methodologies utilised (ie hand auger).

8.2. GeneralFieldwork was carried out between 14 and 17 May 2018 by a Coffey environmental scientist.

Prior to ground disturbance, each borehole location was cleared for underground services by an accredited underground service locator. This included the use of ground penetrating radar (GPR) where permissible to do so to confirm the presence of non-conductive materials such stormwater pipes, irrigation or underground petroleum structures. GPR was not able to be carried out at the BP Service Station site or the M4 Embankments due to obstructions.

Non-destructive digging was carried out using a hand auger to mitigate contact and disturbance of underground services, where required.

Borehole logs are provided in Appendix F.

Boreholes not converted to soil vapour monitoring wells were reinstated after sampling with the spoil recovered during auguring in reverse order.



8.3. Soil Sampling and Field ScreeningA total of 25 boreholes were advanced using a hand auger across all four sites as detailed in Table E in Section 8.5.

Soil samples were collected from varying depths including from the surface of the soil and generally every 0.5 m or change in lithological unit. Soil samples were collected from the hand auger using disposable nitrile gloves and between each sampling location to reduce the potential for cross contamination.

The soil samples were placed in laboratory-supplied containers and transported to the laboratory inice-cooled eskies under standard chain of custody procedure.

Subsurface conditions were logged in general accordance with AS 1726-2017. A photo-ionisation detector (PID) was used to screen the soil samples for the potential presence of volatile organic compounds (VOCs) and suspected hydrocarbon impact during sampling. The soil samples collected and PID readings are detailed on the borehole logs provided in Appendix D.

8.4. Soil Vapour SamplingTwo temporary soil vapour wells were installed by direct driving a sampling rod to a depth of 1 m, prior to lifting the screen sleeve and collecting a sample. One was located at the BP service station site (BH1/SV1) and one at the Shell/Coles Express service station site (BH12/SV2).

Vapour samples were collected using individually certified Summa® canisters at each location. Summa® canisters are evacuated stainless steel chambers that provide a non-intrusive, active sampling method to collect a bulk soil gas sample over a specified time period. The canisters were1.4 L in volume and fitted with a 60 millilitre per minute regulator. The regulators allowed the vapour tobe sampled at a relatively constant rate over the selected sampling period.

The use of Summa® canisters allows appropriate analytical methods to be used that provide accurate determination of a large range of low level VOCs in air. Summa® canisters were certified clean by the analysing laboratory Australian Laboratory Services (ALS) and used within appropriate holding times. The pressure change in the canisters was noted at regular times during sampling and the pressure was noted to drop at a constant rate.

The vacuum pressure for each canister was checked prior to sampling, after sample collection and upon receipt at the laboratory. A vacuum pressure after sampling of between 5 and 10 inches of mercury (“Hg) is considered to be representative of constant controlled flow sampling rate and collection of a complete sample. A vacuum pressure difference of less than 5 “Hg between sample dispatch (after sample collection) and sample receipt is deemed acceptable.

The canister vacuum pressures recorded after sample collection were -5 psi for BH1/SV1 canister and -6 psi for BH12/SV2 canister and the pressure difference between sample dispatch and receipt was less than 2 psi. Differences in the vacuum readings in the field and laboratory can be attributable to a variety of reasons including change in temperatures, changes in barometric pressure or differences in instrument accuracy. The accuracy of the vacuum readings in the laboratory are greater than gauges used in the field and it is likely that the small differences in pressure readings between vacuum after sampling and vacuum on receipt by laboratory are due to differences in instrumentation.

All samples collected were sent under chain of custody to ALS which is a NATA accredited laboratory for the BTEX and TRH compounds (aliphatic and aromatic fractions).

A copy of the field sheets are provided in Appendix E and a copies of the calibration records for the sampling equipment are provided in Appendix F.



8.5. Laboratory AnalysisSamples were analysed at laboratories holding accreditation to ISO 17025 General requirements for the competence of testing and calibration laboratories and using National Association of Testing Authorities (NATA) accredited methods compliant with amended ASC NEPM 2013 Schedule B3 Laboratory Analysis of Potentially Contaminated Soils referenced to USEPA and APHA methods.

Copies of the laboratory analytical reports are provided in Appendix J.

Soil samples were analysed by Eurofins MGT Pty Ltd (Eurofins). Selected soil samples were analysed for the analytical suite outlined in Table E. Soil samples analysed for asbestos were selected from fill material only.

Sampling location frequencies met the NSW EPA Sampling Design Guideline requirements for each of the sites based on the areas detailed in Table A (Section 1.1). The minimum number of sampling points required for a 500 m2 area is 5 sample points and 6 sample points for a 1,000 m2 area.

Assessment CriteriaAnalytical results of soil and soil vapour samples were compared against the following criteria and screening levels. These criteria are considered applicable for the current land use and proposed future land use.

9.1. Soil Health Investigation Levels (HILs)HILs relevant to commercial/industrial land use were adopted from ASC NEPM 2013.

HILs are deemed applicable for assessing human health risk via all relevant exposure pathways of exposure for metals and organic substances. HILs are concentrations below which contaminants insoils are not considered to adversely affect human health. The adopted HILs for assessment of soilare presented in Table 1 (Appendix B).

9.2. Soil Health Screening Levels (HSLs)Soil HSLs are provided in ASC NEPM 2013 for selected petroleum compounds and fractions and are considered applicable to assessing human health risk via vapour intrusion and inhalation. The HSLs depend on specific soil physicochemical properties, land use scenarios, and the characteristics of building structures. They apply to different soil types, and depths below surface to >4m bgl.

Soil HSLs were also adopted from CRCCARE 2011 to assess the exposure pathway of:

• Direct contact (oral ingestion, dermal contact and dust inhalation) for commercial / industrialworkers and intrusive maintenance workers

• Vapour intrusion for intrusive maintenance workers (maximum trench depth of 1.0 m)

As a conservative approach, a sandy soil type and depth of 0-<2 m was adopted. Workers working in deeper excavations are anticipated to have their own management plan as part of the work, health and safety procedures.

The soil HSLs adopted are presented in Table 1 (Appendix B).

9.3. Petroleum Hydrocarbon Management LimitsPetroleum hydrocarbon management limits provided in ASC NEPM 2013 were considered applicable for assessing petroleum hydrocarbons in soil to avoid or minimise the following potential effects of petroleum hydrocarbon contamination:

• Formation of observable light non-aqueous phase liquid (LNAPL)• Fire and explosion hazards

• Effects on buried infrastructure (i.e. penetration of, or damage to, in-ground services byhydrocarbons)

• Aesthetics

Management limits for a commercial/industrial land use with coarse soil texture were adopted for this assessment are presented in Table 1 (Appendix B).



9.4. Soil Vapour HSLs for Vapour IntrusionSoil vapour HSLs for selected petroleum compounds and fractions have been adopted fromASC NEPM 2013 as they are considered applicable to assessing human health risk via the vapourintrusion pathway. The HSLs depend on specific soil physicochemical properties, land use scenarios,and the characteristics of building structures. They apply to different soil types, and depths belowsurface to >8m bgl. The adopted soil vapour HSLs for assessment of soil vapour are presented inTable 2 (Appendix B).

9.5. Ecological Investigation and Screening LevelsAssumptions were made regarding the adoption of ecological investigation levels (EILs). First, the soil type at each location was taken into consideration. As the predominant soil type is clay, a pH of 6.0, CEC of 30 cmol/kg and clay content of >10% was adopted. ABC’s were derived from Imray et al (1995)2 for NSW old suburbs and high traffic (adopting the 25th percentile).

Coffey conducted a review of the background documents used to derive the ecological screening levels (ESLs) for benzo(a)pyrene as prescribed in Schedule B1 of the amended ASC NEPM. The review identified that the ESLs were heavily based on the 1999 Canadian Soil Quality Guideline (SQG) values (Warne, 2010). Due to the availability of a significant amount of new toxicity data, the Canadian values were revised in 2010 (CCME, 2010), however these revisions were not considered in the amended ASC NEPM. As such, Coffey considers that the low reliability ESLs prescribed in Schedule B1 of the amended ASC NEPM are now out dated and the Canadian Soil Quality Guidelines for Environmental Health (SQGE) have been adopted (CCME, 2010). The Canadian SQGE for B(a)P (20mg/kg) has been derived based on a similar methodology to that prescribed in Schedule B5b of the amended ASC NEPM (i.e. based on the species sensitivity distribution approach).

9.6. Asbestos in SoilFor asbestos in soil, a screening level of 0.1g/kg (0.01 % w/w equivalent) was adopted based on the laboratory detection limit for analysis of asbestos in non-homogenous samples using the methodology outlined in Australian Standard AS 4964 – 2004: Method for the Qualitative Identification of Asbestos in Bulk Samples (AS4964-2004). Furthermore, where trace analysis is carried out during analysis, an assessment criteria of ‘no respirable fibres’ has been adopted; a detection of respirable fibres would indicate an exceedance of the assessment criteria. Furthermore, the laboratory provides additional comments of visual observations made during analysis relating to the presence of visible Fibrous Asbestos (FA) and Asbestos Fines (AF) (if present). These observations are noteworthy, based on the weight of evidence approach, in accordance with the amended ASC NEPM 2013.

10.2. Soil Analytical ResultsA summary table of soil analytical results compared to the adopted soil assessment criteria is presented in Table 1 (Appendix B).

A review of the analytical results indicates that concentrations of CoPC within samples analysed were less than the laboratory practical quantitation limit (PQL), and/or the adopted soil assessment criteria, and the adopted screening level for asbestos in soil except for the following:

• TRH C16-C34 (ESL for public open space) - criteria 300 mg/kgn BH12_0.0-0.1m reported 710 mg/kg (Shell/Coles Express)n BH12_0.3-0.4m reported 520 mg/kg (Shell/Coles Express)n BH13_0.0-0.1m reported 330 mg/kg (Shell/Coles Express)

No asbestos was reported within the samples collected and analysed.

10.3. Soil Vapour ResultsA summary table of the soil vapour analytical results are presented in Table 2 (Appendix B).

A review of the soil vapour analytical results indicates that neither of the soil vapour samples collected reported concentrations of CoPC above the PQL.

11. Quality Assurance and Quality Control (QA/QC)In summary, the following QA/QC findings are noted:

• Sampling was conducted in fine weather on consecutive days by the same person who wasappropriately trained and experienced for the task

• Samples were collected from pre-determined locations and to target depths where practicable

• Analytical laboratories were NATA accredited for the analyses requested and NATA endorsedlaboratory certificates were issued

• RPDs (blind and split duplicate) samples were within acceptable limits as defined in the DQO’sprovided in Appendix C. RPD results are provided in Table 3 (Appendix B)

• Samples submitted to the laboratory were chilled and within the required holding timeframes forthe required analytical test methods performed

• Field rinsate samples collected and trip blank and trip spike samples reported contaminantconcentrations below the laboratory limit of reporting (refer to Table 4 and Table 5, Appendix B))

• Laboratory QAQC – internal laboratory duplicates, method blanks, surrogates and matrix spikeswere within acceptable limits

Based on the review of field and laboratory QA/QC results, the quality of the data generated from this assessment are considered reliable and suitable for the purposes of the assessment.



DiscussionSoil samples were collected and analysed from a total of 25 boreholes for relevant CoPC across the four sites. Based on a review of the laboratory results, only one of the sites (Shell/Coles Express) reported concentrations in exceedance of any adopted criteria. Two locations (BH12 and BH13) reported concentrations of TRH C16-C34 greater than the adopted ESLs for public open space. This is indicative of potential surface spillage of heavy end hydrocarbon fractions (such as engine oil) and is not likely to be the result of significant contamination arising from leaking underground storage tanks (USTs) or associated petroleum infrastructure. The highest TRH concentrations were reported in the surface soils and decrease with depth. The resulting soil vapour sample collected at this location (BH12/SV2) reported concentrations of all analytes tested below the laboratory PQL and below any adopted screening criteria, therefore resulting in an acceptable vapour risk to construction workers.

Groundwater was not assessed a part of this investigation. Should construction work for the roadway require excavation to depths of greater than 6 mbgl (ie the expected depth of groundwater), groundwater assessment may be required. Groundwater flow direction from the BP Service Station site is expected to be towards the Nepean River located to the west. As such, groundwater may be hydrocarbon impacted as the acquisition area is located hydraulically downgradient from UST infrastructure. However, results from the soil vapour sampling conducted at BH1/SV1 indicates a low potential for presence of hydrocarbon within soil vapour.

Some minor staining was visible on the plinth at the BP Service Station site and is expected some minor localised contamination may be present beneath the plinth that may require removal prior to construction and further assessment/validation.

Dependent on the design of the road and road verge, it is likely that the areas at these locations (ie boreholes BH12 and BH13) will be located under hardstand supporting low ecological values and therefore represent an acceptable risk to ecological communities. If the road verge is to be vegetated, remedial measures may be required including removal of impacted soils.

The depth of the sampling at the M4 embankments was limited to surface soils (ie 0.4m) because of the sampling techniques employed and the use of mechanical methods was not feasible. Although a definitive statement cannot be made regarding the potential for contamination deeper within the embankment fill material, it is likely the material is consistent in with depth as it is expected to have been placed within a short timeframe and likely obtained from same source material. Further confirmatory assessment may be required during construction.

ConclusionsCoffey has completed a contamination assessment across portions of four sites for due diligence purposes prior to the acquisition of land as part of the Mulgoa Road upgrade project by Roads and Maritime.

A summary of findings is presented as follows:

• The soil material encountered at each borehole was largely natural clay material overlying thinlayer of topsoil. No visual or olfactory evidence of contamination was encountered at the locationssampled. Some soils located at the M4 embankment encountered fill material but appeared as reworked natural clays. The soil assessment was limited in depth to the top 0.8m.

• No suspected asbestos impacted fill was found and analytical results reported no detection ofasbestos, including no loose asbestos fibres by trace analysis.



• Soil vapour reported concentrations below the PQL and relevant criteria at each of the soil vapourwells located at Shell/Coles Express and BP service station sites.

• Soils and soil vapour (Shell/Coles and BP only) were assessed for suitability for the proposed useat each site and are considered acceptable for use as a roadway. Results are also considered asnot presenting any potential risks to construction worker health and safety.

• Soils were also assessed for ecological suitability and are considered to be acceptable forplacement within a roadway except for two borehole locations (BH12 and BH13, Shell/ColesExpress) where TRH C16-C34 reported concentrations exceeding the ESL criteria for public open space. Note concentrations were considered acceptable for commercial/ industrial land use and as such if the shallow soils within vicinity of these boreholes are covered with pavement the risk to ecology would be considered to be acceptable. Alternatively, these soils may be removed and disposed offsite. At detailed design phase, contamination can be managed through preparation and implementation of a Remedial Action Plan (RAP) (if capping onsite) or through construction practices as detailed within a Construction Environmental Management Plan (CEMP) if disposing offsite.

Appendix C – Data Quality Objectives

DATA QUALITY OBJECTIVES

Step 1 – State the Problem

Roads and Maritime Services propose to acquire small portions of land to assist in the widening of Mulgoa Road. A previous desktop study undertaken at the site identified four sites as high-risk with historical or current land uses comprising petroleum use and/or potential for contaminated fill placement.

It is understood that this contamination assessment is for due diligence purposes related to the purchase of land.

Step 2 - Identify the Decisions

The decisions to be made based on the results of the investigation were as follows:

• What are the CoPC associated with potential soil and vapour contamination?

• Are CoPC present within soil or vapour, and if so, do they present an unacceptable risk to human health orthe environment for the proposed redevelopment as public open space land use?

• If soil contamination is present, does the site require remediation works and/or a management plan prior toacquisition or redevelopment to render the site suitable for use?

Step 3 - Identify Inputs in the Decision

The inputs required to make the above decisions were as follows:

• Site setting and available background information;

• Selection of appropriate Tier 1 soil and soil vapour assessment criteria and waste classification assessmentcriteria;

• Visual observations; and

• Field and laboratory analytical results.

Step 4 - Define Boundaries of the Study

The boundaries of the investigation were identified as follows:

• Spatial boundaries: the spatial boundary of the site was defined as the proposed portion of land to beacquired and vertically as the depth of hand augers (up to 1m).

• Temporal boundaries: The current status of the sampling points at the time of the investigation.

Step 5 - Develop a Decision Rule

The purpose of this step was to define the parameter of interest, specify the action level and combine the outputs of the previous DQO steps into an ‘if/then’ decision rule that defines the conditions that would cause the decision maker to choose alternative actions.

If the levels of chemicals of potential concern were below the adopted soil assessment criteria, the risk to human health and the environment at that location could be considered to be low.

If concentrations of contaminants exceed the adopted assessment criteria, consideration for statistical analysis of the dataset (if size of dataset allows) should be undertaken to support the need or otherwise for further assessment, remediation or site management. These decision rules include the 95% upper confidence limit (UCL) of the mean contaminant concentration being less than the adopted site assessment criteria, the standard deviation being less than 50% and no individual concentration being in excess of 250% of the site assessment criteria (for similar soil types).

Statistical appraisal does not apply to asbestos. If asbestos-containing material (ACM) is suspected in the >7mm fraction during field screening, the suspected ACM should be collected and analysed as per AS 4964—2004. Australian Standard. Method for the qualitative identification of asbestos in bulk samples, to confirm

presence/absence of asbestos. The type, nature, presence and percentage of asbestos may trigger the requirement for further investigation, management or remediation.

The spatial extent of data should be considered to assess whether additional data gaps require investigation.

If the quality control (QC) results meet the data quality indicators (DQI), then the analytical data is considered suitable and reliable for the purpose of this contamination investigation.

Step 6 - Specify the performance or acceptance criteria

There are two types of decision errors:

• Sampling errors, which occur when the samples collected are not representative of the conditions within theinvestigation area; and

• Measurement errors, which occur during sample collection, handling, preparation, analysis and datareduction.

The null hypothesis, which is an assumption assumed to be true in the absence of contrary evidence, for this study is ‘The site is contaminated and thus not suitable for use’.

These errors may lead to the following decision errors:

• Type I error - Rejecting the hypothesis as false when it is really true: Deciding that contamination is notpresent when the reverse is true; and

• Type II error - Accepting the hypothesis as true when it is really false: Deciding that contamination is presentwhen the reverse is true.

An assessment will be made as to the likelihood of a decision error being made based on the results of a QA/QC assessment and the closeness of the data to assessment criteria. Additionally, statistical methods such as 95% Upper Confidence Limit (UCL) calculations may be utilised, where applicable.

The acceptable limits on decision errors applied during this investigation and the manner of addressing possible decision errors were developed based on the data quality indicators (DQIs) of:

• Accuracy: a quantitative measure of the closeness of reported data to the true value;

• Comparability: a qualitative parameter expressing the confidence with which one (1) data set can becompared with another;

• Completeness: a measure of the amount of useable data (expressed as %) from a data collection activity;

• Representativeness: the confidence (expressed qualitatively) that data are representative of each mediapresent on the site; and

• Precision: a quantitative measure of the variability (or reproducibility) of data.

Step 7 - Optimise the Design

The purpose of this step was to identify a resource-effective data collection design for generating data that satisfies the DQOs.

This assessment was designed considering the information provided during the request for proposal.

A proposal was prepared for the Stage 2 ESA which outlined a proposed field program. The field program was reviewed at critical times during the project and amended where necessary based on site conditions, unexpected finds, professional judgement and liaison with ARUP.

To ensure the design satisfied the DQOs, DQIs (for accuracy, comparability, completeness, precision and reproducibility) were established to set acceptance limits on field methodologies and laboratory data collected.

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.

Internal Quality Control Review and Glossary

General1. 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/food 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 except for PFAS compounds.

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.

Holding TimesPlease 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 SRA.

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.

For VOCs containing vinyl chloride, styrene and 2-chloroethyl vinyl ether the holding time is 7 days however for all other VOCs such as BTEX or C6-10 TRH then the holding time is 14 days.

**NOTE: pH duplicates are reported as a range NOT as RPD

Unitsmg/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

TermsDry 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 and 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.

SRA Sample Receipt Advice

QSM Quality Systems Manual ver 5.1 US Department of Defense

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

QC - Acceptance CriteriaRPD 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

PFAS field samples that contain surrogate recoveries in excess of the QC limit designated in QSM 5.1 where no positive PFAS results have been reported have been reviewed and no data wasaffected.

QC Data General Comments1. 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 Parentand 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 reportedin 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.

Q08

F2 is determined by arithmetically subtracting the "naphthalene" value from the ">C10-C16" value. The naphthalene value used in this calculation is obtained from volatiles (Purge & Trap analysis).Where we have reported both volatile (P&T GCMS) and semivolatile (GCMS) naphthalene data, results may not be identical. Provided correct sample handling protocols have been followed, any observed differences in results are likely to be due to procedural differences within each methodology. Results determined by both techniques have passed all QAQC acceptance criteria, and are entirely technically valid.F1 is determined by arithmetically subtracting the "Total BTEX" value from the "C6-C10" value. The "Total BTEX" value is obtained by summing the concentrations of BTEX analytes. The "C6-C10" value is obtained by quantitating against a standard of mixed aromatic/aliphatic analytes.Please note:- These two PAH isomers closely co-elute using the most contemporary analytical methods and both the reported concentration (and the TEQ) apply specifically to the total of the two co-eluting PAHsThe matrix spike recovery is outside of the recommended acceptance criteria. An acceptable recovery was obtained for the laboratory control sample indicating a sample matrix interference

Q15 The RPD reported passes Eurofins | mgt's QC - Acceptance Criteria as defined in the Internal Quality Control Review and Glossary page of this report.R20 This sample is a Trip Spike and therefore all results are reported as a percentage

Methodology: Asbestos FibreIdentification

Unknown Mineral Fibres

Subsampling Soil Samples

Bonded asbestos- containing material (ACM)

Conducted in accordance with the Australian Standard AS 4964 – 2004: Method for the Qualitative Identification of Asbestos in Bulk Samples and in-house Method LTM-ASB-8020 by polarised light microscopy (PLM) and dispersion staining (DS) techniques.NOTE: Positive Trace Analysis results indicate the sample contains detectable respirable fibres.

Mineral fibres of unknown type, as determined by PLM with DS, may require another analytical technique, such as Electron Microscopy, to confirm unequivocal identity.NOTE: While Actinolite, Anthophyllite and Tremolite asbestos may be detected by PLM with DS, due to variability in theoptical properties of these materials, AS4964 requires that these are reported as UMF unless confirmed by anindependent technique.

The whole sample submitted is first dried and then passed through a 10mm sieve followed by a 2mm sieve. All fibrous matter greater than 10mm, greater than 2mm as well as the material passing through the 2mm sieve are retained and analysed for the presence of asbestos. If the sub 2mm fraction is greater than approximately 30 to 60g then a subsampling routine based on ISO 3082:2009(E) is employed.NOTE: Depending on the nature and size of the soil sample, the sub-2 mm residue material may need to be sub-sampled for trace analysis, in accordance with AS 4964-2004.

The material is first examined and any fibres isolated for identification by PLM and DS. Where required, interfering matrices may be removed by disintegration using a range of heat, chemical or physical treatments, possibly in combination.The resultant material is then further examined in accordance with AS 4964 - 2004.NOTE: Even after disintegration it may be difficult to detect the presence of asbestos in some asbestos-containing bulkmaterials using PLM and DS. This is due to the low grade or small length or diameter of the asbestos fibres present inthe material, or to the fact that very fine fibres have been distributed intimately throughout the materials. Vinyl/asbestosfloor tiles, some asbestos-containing sealants and mastics, asbestos-containing epoxy resins and some ore samples areexamples of these types of material, which are difficult to analyse.

Limit of Reporting The performance limitation of the AS4964 method for inhomogeneous samples is around 0.1 g/kg (0.01% (w/w)). Whereno asbestos is found by PLM and DS, including Trace Analysis where required, this is considered to be at the nominalreporting limit of 0.01 % (w / w).The examination of large sample sizes(500 mL is recommended) may improve thelikelihood of identifying ACM in the > 2mm fraction.The NEPM screening level of 0.001 % (w / w) asbestos in soil forFA(friable asbestos) and AF(asbestos fines) then applies where they are able to be quantified by gravimetricprocedures.This quantitative screening is not generally applicable to FF(free fibres) and results of Trace Analysis arereferred.NOTE: NATA News March 2014, p.7, states in relation to AS4964: “This is a qualitative method with a nominal reportinglimit of 0.01%” and that currently in Australia “there is no validated method available for the quantification of asbestos”.Accordingly, NATA Accreditation does not cover the performance of this service (indicated with an asterisk).This report is consistent with the analytical procedures and reporting recommendations in the National EnvironmentProtection (Assessment of Site Contamination) Measure, 2013 (as amended) and the Western Australia Guidelines forthe Assessment, Remediation and Management of Asbestos-Contaminated Sites in Western Australia, 2009, includingsupporting document Recommended Procedures for Laboratory Analysis of Asbestos in Soil, June 2011.

ACM Bonded asbestos-containing material means any material containing more than 1% asbestos and comprises asbestos-containing-material which is in sound condition,although possibly broken or fragmented, and where the asbestos is bound in a matrix such as cement or resin. Common examples of ACM include but are not limited to: pipe and boiler insulation, sprayed-on fireproofing, troweled-on acoustical plaster, floor tile and mastic, floor linoleum, transite shingles, roofing materials, wall and ceiling plaster, ceiling tiles, and gasket materials. This term is restricted to material that cannot pass a 7 mm x 7 mm sieve. This sieve size is selected because it approximates the thickness of common asbestos cement sheeting and for fragments to be smaller than this would imply a high degree of damage and hence potential for fibre release.

FA FA comprises friable asbestos material and includes severely weathered cement sheet, insulation products and woven asbestos material. This type of friable asbestosis defined here as asbestos material that is in a degraded condition such that it can be broken or crumbled by hand pressure. This material is typically unbonded or was previously bonded and is now significantly degraded (crumbling).

PACM Presumed Asbestos-Containing Material means thermal system insulation and surfacing material found in buildings, vessels, and vessel sections constructed no laterthan 1980 that are assumed to contain greater than one percent asbestos but have not been sampled or analyzed to verify or negate the presence of asbestos.

AF Asbestos fines (AF) are defined as free fibres, or fibre bundles, smaller than 7mm. It is the free fibres which present the greatest risk to human health, although verysmall fibres (< 5 microns in length) are not considered to be such a risk. AF also includes small fragments of bonded ACM that pass through a 7 mm x 7 mm sieve. (Note that for bonded ACM fragments to pass through a 7 mm x 7 mm sieve implies a substatntial degree of damage which increases the potential for fibre release.)

AC Asbestos cement means a mixture of cement and asbestos fibres (typically 90:10 ratios).

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

QC - Acceptance CriteriaRPD 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

PFAS field samples that contain surrogate recoveries in excess of the QC limit designated in QSM 5.1 where no positive PFAS results have been reported have been reviewed and no data wasaffected.

QC Data General Comments1. 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 Parentand 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 reportedin 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.

F2 is determined by arithmetically subtracting the "naphthalene" value from the ">C10-C16" value. The naphthalene value used in this calculation is obtained from volatiles (Purge & Trap analysis).Where we have reported both volatile (P&T GCMS) and semivolatile (GCMS) naphthalene data, results may not be identical. Provided correct sample handling protocols have been followed, any observed differences in results are likely to be due to procedural differences within each methodology. Results determined by both techniques have passed all QAQC acceptance criteria, and are entirely technically valid.F1 is determined by arithmetically subtracting the "Total BTEX" value from the "C6-C10" value. The "Total BTEX" value is obtained by summing the concentrations of BTEX analytes. The "C6-C10" value is obtained by quantitating against a standard of mixed aromatic/aliphatic analytes.Please note:- These two PAH isomers closely co-elute using the most contemporary analytical methods and both the reported concentration (and the TEQ) apply specifically to the total of the two co-eluting PAHs

General CommentsThe 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.

When sampling time information is not provided by the client, sampling dates are shown without a time component. In these instances, the time component has been assumed by the laboratory for processingpurposes.

Where a result is required to meet compliance limits the associated uncertainty must be considered. Refer to the ALS Contact for details.

Key : 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^ = This result is computed from individual analyte detections at or above the level of reportingø = ALS is not NATA accredited for these tests.~ = Indicates an estimated value.

l EP071: Results of sample DUP02A have been confirmed by re-extraction and re-analysis.

Benzo(a)pyrene Toxicity Equivalent Quotient (TEQ) is the sum total of the concentration of the eight carcinogenic PAHs multiplied by their Toxicity Equivalence Factor (TEF) relative to Benzo(a)pyrene. TEF values are provided in brackets as follows: Benz(a)anthracene (0.1), Chrysene (0.01), Benzo(b+j) & Benzo(k)fluoranthene (0.1), Benzo(a)pyrene (1.0), Indeno(1.2.3.cd)pyrene (0.1), Dibenz(a.h)anthracene (1.0), Benzo(g.h.i)perylene (0.01). Less than LOR results for 'TEQ Zero' are treated as zero, for 'TEQ 1/2LOR' are treated as half the reported LOR, and for 'TEQ LOR' are treated as being equal to the reported LOR. Note: TEQ 1/2LOR and TEQ LOR will calculate as 0.6mg/Kg and 1.2mg/Kg respectively for samples with non-detects for all of the eight TEQ PAHs.

General CommentsThe 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 housedeveloped procedures are employed in the absence of documented standards or by client request.


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.

Key : Anonymous = Refers to samples which are not specifically part of this work order but formed part of the QC process lotCAS 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 reportingRPD = Relative Percentage Difference# = Indicates failed QC

Laboratory Duplicate (DUP) ReportThe quality control term Laboratory Duplicate refers to a randomly selected intralaboratory split. Laboratory duplicates provide information regarding method precision and sample heterogeneity. The permitted rangesfor 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) ReportThe 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 highlights outliers flagged in the Quality Control (QC) Report.l NO Method Blank value outliers occur.l NO Duplicate outliers occur.l NO Laboratory Control outliers occur.l NO Matrix Spike outliers occur.l For all regular sample matrices, NO surrogate recovery outliers occur.

Outliers : Analysis Holding Time Compliancel NO Analysis Holding Time Outliers exist.

Outliers : Frequency of Quality Control Samplesl NO Quality Control Sample Frequency Outliers exist.



Analysis Holding Time ComplianceIf 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.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: organics14 days, mercury 28 days & other metals 180 days. A recorded breach does not guarantee a breach for all non-volatile parameters.

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.

General CommentsThe 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 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 sampling time information is not provided by the client, sampling dates are shown without a time component. In these instances, the time component has been assumed by the laboratory for processingpurposes.

Where a result is required to meet compliance limits the associated uncertainty must be considered. Refer to the ALS Contact for details.

Key : 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^ = This result is computed from individual analyte detections at or above the level of reportingø = ALS is not NATA accredited for these tests.~ = Indicates an estimated value.

EP101, EP103: Results reported in mg/m³ are calculated from PPMV results based on a temperature of 25°C and atmospheric pressure of 101.3 kPa.

CAN-001: Results for Pressure - As Received are measured under controlled conditions using calibrated laboratory gauges. These results are expressed as an Absolute Pressure. Equivalent gauge pressures may be calculated by subtracting the Pressure - Laboratory Atmosphere taken at the time of measurement.CAN-001: Results for Pressure - Gauge as Received are obtained from uncalibrated field gauges and are indicative only. These results may not precisely match calibrated gauge readings and may vary from fieldmeasurements due to changes in temperature and pressure

Dates reported represent first date of extraction or analysis and preclude subsequent dilutions and reruns. A listing of breaches (if any) is provided herein.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: organics14 days, mercury 28 days & other metals 180 days. A recorded breach does not guarantee a breach for all non-volatile parameters.

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.

General CommentsThe 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 housedeveloped procedures are employed in the absence of documented standards or by client request.


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.

Key : Anonymous = Refers to samples which are not specifically part of this work order but formed part of the QC process lotCAS 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 reportingRPD = Relative Percentage Difference# = Indicates failed QC

Laboratory Duplicate (DUP) ReportThe quality control term Laboratory Duplicate refers to a randomly selected intralaboratory split. Laboratory duplicates provide information regarding method precision and sample heterogeneity. The permitted rangesfor 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), Laboratory Control Spike (LCS) and Laboratory Control Spike Duplicate (DCS) ReportThe 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 terms Laboratory Control Sample (LCS) and Laboratory Control Sample Duplicate (DCS) refers to certified reference materials, or known interference free matrices spiked with target analytes. The purpose of these QC parameters are to monitor method precision and accuracy independent of sample matrix. Dynamic Recovery Limits are based on statistical evaluation of processed LCS and DCS.
