1. INTRODUCTION

Geotesta was engaged by Bathla Group Pty Ltd to validate the findings of site

contamination assessment studies conducted on property 57, 51 and 45 Gordon Road

Scholfields, NSW. A detailed investigation was conducted by Martens and Associates

Ltd Pty and the findings were presented in a report titled “Martens and Associates

(2015), Stage 2 Environmental Site Assessment: Lots 36, 37 and 38, DP 39341, 57, 51 and 45

Gordon Road, Schofields, NSW, report reference P1404469JR03V01 [1]. A Remedial Action

Plan was performed by Geotesta and the findings were presented in a report titled

“Remedial Action Plan: 57, 51 and 45 GORDON ROAD, SCHOLFIELDS” [2].

Based on the steps presented in the Remedial Action Plan report for the site validation

study, Geotesta have reviewed the works conducted for the detailed soil

contamination assessment and the remedial action plan and conducted additional soil

samplings and contamination testings. The findings of Geotesta’s review and

assessment are presented in the following sections of this report.

2. OBJECTIVE AND SCOPE

The objective of this investigation is validation of the remedial works proposed in the

Remedial Action Plan report [2] for the site. The general objective to be adhered is

recommending the suitability of the site for proposed residential development in

relation to the management of contamination.

The scope of the study is as following:

1. Reviewing the previous studies performed in the site and the validation

criteria

2. Performing the validation sampling program

3. Laboratory assessment

4. Reporting on the above steps

3. BACKGROUND

The site is located at 57, 51 and 45 Gordon Road, Schofields, NSW, in the local

government area of Blacktown and registered as Lots 36, 37 and 38, DP 39341. It is

approximately a parallelogram shape having an area of approximately 6.1 ha. All the

structures in the subject site including the dwellings and sheds have been demolished

and the remedial action plan operations have been carried out at the time of

inspection.

The Penrith 1:100,000 Geological Series Sheet 9030 (1991) indicates that the site is

underlain by Bringelly Shale which comprises shale, carbonaceous claystone,

claystone, laminite, fine to medium grained lithic sandstone and rare coal/tuff.

The 1:100,000 Soil Landscape Series Sheet (1989) indicates site soils comprise the

Blacktown soil landscape which consists of shallow to moderately deep (<1 m) hard

setting mottled texture contrast soils, red and brown podzolic soils on crests grading

to yellow podzic soils on lower slopes and in drainage lines.

The soil largely consists of medium stiff to stiff clays/silty clays and generally with low

permeability. The top layer of the soil appeared to be disturbed due to construction

and vegetation activities.

The report of soil contamination assessment by Martens and Associates included the

collection and testing of soil samples. Samples were tested and the laboratory results

of heavy metals (26 samples), concentrations of PAH, TPH and BTEX (13 samples),

OCP/OPP (23 samples) and asbestos (10 samples) are presented in the Martens report

dated 2016 [1]. The results of the detailed site investigation are summarized in the

followings.

3.1. Discussion of the Previous Detailed Site Investigation

The concentration of lead was detected in 1 sample at the adopted SAC of 300 mg/kg.

4469/HS12 (300 mg/kg). The concentrations of PAH, BTEX in HS02, HS06 was above

the adopted Site Assessment Criteria (SAC). F2 – C 10 – C 16 was detected over the

adopted HSL (110 mg/kg) in samples 4469/HS02 (500 mg/kg) and 4469/HS06 (330

mg/kg). F2 – C 10 – C 16 was detected over the adopted ESL (120 mg/kg) in samples

4469/HS02 (500 mg/kg) and 4469/HS06 (330 mg/kg). F3 – C 16 – C 34 was detected over

the adopted ESL (1,300 mg/kg) in samples 4469/HS02 (4,100 mg/kg) and 4469/HS06

(25,000mg/kg). F4 – C 34 – C 40 was detected above the adopted ESL (5,600mg/kg) in

sample 4469/HS06 (10,000 mg/kg). F3 – C 16 – C 34 was detected over the adopted


4

direct contact (4,500 mg/kg) in sample 4469/HS06 (25,000 mg/kg). F4 – C 34 – C 40 was

detected above the adopted direct contact (6,300 mg/kg) in sample 4469/HS06 (10,000

mg/kg). ACM was identified at one location (ASB1) in the form of a fibre cement

sheeting fragment. A remediation action plan was recommended by Geotesta which

included a data gap closure investigation. In addition to that, a validation study was

also recommended after demolition of dwellings and sheds. The soil samplings are to

be carried out beneath the dwellings and sheds and the location of identified concerns

as explained above.

4. INVESTIGATION, SAMPLING AND RESULTS

4.1. Geotesta Investigation

Geotesta conducted additional soil sampling and analysis for soil contamination to

assess the site contamination post earthworks. Geotesta collected 20 soil samples from

those areas identified in the Martens report for which the sampling has not been

carried out in the DSI. Sampling was conducted on 10 April 2017.

The soil samples were analysed by Eurofins MGT which is NATA accredited for the

analysis conducted. Site plan and sampling locations are illustrated in Figure 1.

Figure 1: Site Plan and Sampling Locations

4.2. Geotesta results

Geotesta collected an additional 20 soil samples for soil contamination beneath the

dwellings and sheds. The samples were checked for PAH, BTEX, TRH, heavy metals,

OCP/OPP and asbestos concentrations. In the following summary of the test results is

presented. The results of the lab tests presented in Appendix A are summarized in the

following.


6

Heavy Metals

A total of sixteen samples (BH1-4, 6-7, 9-15, 17-19) were analysed for a range of heavy

metals consisting of As, Cd, Cr, Cu, Pb, Hg, Ni and Zn.

• Arsenic concentrations ranging less than 3.2-19 mg/kg.

• Cadmium concentrations were less than 0.4 mg/kg

• Total Chromium concentrations ranging from 7.1-34 mg/kg.

• Copper concentrations ranging from 5.0-9.4 mg/kg.

• Lead concentrations ranging from 8.1-16 mg/kg.

• Mercury concentrations ranging from <0.1 mg/kg.

• Nickel concentrations ranging from <5.6 mg/kg.

• Zinc concentrations ranging from 5.1-39 mg/kg.

As can be observed all the metal concentrations are below the laboratory detection

limit and therefore within the adopted Site Criteria. They are found to be in acceptable

level for residential areas.

Organochlorine Pesticides/ Organophosphorus Pesticides

A total of five samples (BH2, 6, 10, 13 and 16) were analysed for a range of

Organochlorine and Organophosphorus pesticides. All concentrations of OCP/OPP

were found to be below the laboratory detection limit and therefore within the

adopted Site Criteria.

Polycyclic Aromatic Hydrocarbons

A total of six samples (BH2, 4, 9, 11, 13 and 18) were analysed for a range of PAH. All

concentrations of PAH were found to be below the laboratory detection limit and

therefore within the adopted Site Criteria.

Total Recoverable Hydrocarbons - 1999 NEPM Fractions

A total of seven six samples (BH2, 4, 9, 11, 13 and 18) were analysed for TRH. All

samples analysed were found to have concentrations of TRH below the laboratory

detection limit.


7


A total of six samples (BH2, 4, 9, 11, 13 and 18) were analysed for TRH. All samples

analysed were found to have concentrations of TRH below the laboratory detection

limit.

Benzene, Toluene, Ethyl Benzene and Xylene

A total of six samples (BH2, 4, 9, 11, 13 and 18) were analysed for BTEX. All samples

analysed were found to have concentrations of BTEX below the laboratory detection

limit.

Asbestos

Eight samples (BH1, 3, 5, 8, 12, 15, 18, and 20) were tested for Asbestos. From all the

samples, no asbestos was detected. Only organic fibre was detected. No respirable

fibres detected.

All the lab results confirm that earthworks have been undertaken satisfactorily and the

contamination levels are below the threshold levels defined by NEPM 2013


8

5. CONCLUSIONS AND RECOMMENDATIONS

Based on the assessment undertaken, the following conclusions and recommendations

can be made:

Based on the field inspection and laboratory results, Geotesta considers the

overall contamination of the soils to be less than the threshold levels and the site

is considered suitable for the proposed land use for residential development.

During the visual inspection and field works no sign of potential ACM was

observed.

No further contamination investigation is required.

Information about this report

The report contains the results of a geotechnical investigation conducted for a specific

purpose and client. The results should not be used by other parties, or for other

purposes, as they may contain neither adequate nor appropriate information. In

particular, the investigation does not cover contamination issues unless specifically

required to do so by the client.

Test Hole Logging

The information on the test hole logs (boreholes, test pits, exposures etc.) is based on a

visual and tactile assessment, except at the discrete locations where test information is

available (field and/or laboratory results). The test hole logs include both factual data

and inferred information.

Groundwater

Unless otherwise indicated, the water levels presented on the test hole logs are the

levels of free water or seepage in the test hole recorded at the given time of measuring.

The actual groundwater level may differ from this recorded level depending on

material permeability (i.e. depending on response time of the measuring instrument).

Further, variations of this level could occur with time due to such effects as seasonal,

environmental and tidal fluctuations or construction activities. Confirmation of

groundwater levels, phreatic surfaces or piezometric pressures can only be made by

appropriate instrumentation techniques and monitoring programmes.

Interpretation of Results

The discussion or recommendations contained within this report normally are based

on a site evaluation from discrete test hole data. Generalized, idealized or inferred

subsurface conditions (including any geotechnical cross-sections) have been assumed

or prepared by interpolation and/or extrapolation of these data. As such these

conditions are an interpretation and must be considered as a guide only.

Change in Conditions

Local variations or anomalies in the generalized ground conditions do occur in the

natural environment, particularly between discrete test hole locations. Additionally,

certain design or construction procedures may have been assumed in assessing the

soil-structure interaction behaviour of the site. Furthermore, conditions may change at

the site from those encountered at the time of the geotechnical investigation through

construction activities and constantly changing natural forces.

Any change in design, in construction methods, or in ground conditions as noted

during construction, from those assumed or reported should be referred to

GEOTESTA for appropriate assessment and comment.

Geotechnical Verification

Verification of the geotechnical assumptions and/or model is an integral part of the

design process - investigation, construction verification, and performance monitoring.


11

Variability is a feature of the natural environment and, in many instances, verification

of soil or rock quality, or foundation levels, is required. There may be a requirement to

extend foundation depths, to modify a foundation system or to conduct monitoring as

a result of this natural variability. Allowance for verification by geotechnical personnel

accordingly should be recognized and programmed during construction.

Reproduction of Reports

Where it is desired to reproduce, the information contained in our geotechnical report,

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.

1. Laboratory QC results for Method Blanks, Duplicates, Matrix Spikes, and Laboratory Control Samples are included in this QC report where applicable. Additional QC data may be available on

request.

2. All soil results are reported on a dry basis, unless otherwise stated.

3. Actual LORs are matrix dependant. Quoted LORs may be raised where sample extracts are diluted due to interferences.

4. Results are uncorrected for matrix spikes or surrogate recoveries.

5. SVOC analysis on waters are performed on homogenised, unfiltered samples, unless noted otherwise.

6. Samples were analysed on an 'as received' basis. 7. This report replaces any interim results previously issued.

Please refer to 'Sample Preservation and Container Guide' for holding times (QS3001).

For samples received on the last day of holding time, notification of testing requirements should have been received at least 6 hours prior to sample receipt deadlines as stated on the Sample

Receipt Advice.

If the Laboratory did not receive the information in the required timeframe, and regardless of any other integrity issues, suitably qualified results may still be reported.

Holding times apply from the date of sampling, therefore compliance to these may be outside the laboratory's control.

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

mg/kg: milligrams per Kilogram mg/l: milligrams per litre

ug/l: micrograms per litre ppm: Parts per million

ppb: Parts per billion %: Percentage

org/100ml: Organisms per 100 millilitres NTU: Nephelometric Turbidity Units

MPN/100mL: Most Probable Number of organisms per 100 millilitres

Dry Where a moisture has been determined on a solid sample the result is expressed on a dry basis.

LOR Limit of Reporting.

SPIKE Addition of the analyte to the sample and reported as percentage recovery.

RPD Relative Percent Difference between two Duplicate pieces of analysis.

LCS Laboratory Control Sample - reported as percent recovery

CRM Certified Reference Material - reported as percent recovery

Method Blank In the case of solid samples these are performed on laboratory certified clean sands.

In the case of water samples these are performed on de-ionised water.

Surr - Surrogate The addition of a like compound to the analyte target and reported as percentage recovery.

Duplicate A second piece of analysis from the same sample and reported in the same units as the result to show comparison.

Batch Duplicate A second piece of analysis from a sample outside of the clients batch of samples but run within the laboratory batch of analysis.

Batch SPIKE Spike recovery reported on a sample from outside of the clients batch of samples but run within the laboratory batch of analysis.

CP Client Parent - QC was performed on samples pertaining to this report

NCP Non-Client Parent - QC performed on samples not pertaining to this report, QC is representative of the sequence or batch that client samples were analysed within

TEQ Toxic Equivalency Quotient

RPD Duplicates: Global RPD Duplicates Acceptance Criteria is 30% however the following acceptance guidelines are equally applicable:

Results <10 times the LOR : No Limit

Results between 10-20 times the LOR : RPD must lie between 0-50%

Results >20 times the LOR : RPD must lie between 0-30%

Surrogate Recoveries: Recoveries must lie between 50-150%-Phenols & PFASs 20-130%

1. Where a result is reported as a less than (<), higher than the nominated LOR, this is due to either matrix interference, extract dilution required due to interferences or contaminant levels within

the sample, high moisture content or insufficient sample provided.

2. Duplicate data shown within this report that states the word "BATCH" is a Batch Duplicate from outside of your sample batch, but within the laboratory sample batch at a 1:10 ratio. The Parent

and Duplicate data shown is not data from your samples.

3. Organochlorine Pesticide analysis - where reporting LCS data, Toxaphene & Chlordane are not added to the LCS.

4. Organochlorine Pesticide analysis - where reporting Spike data, Toxaphene is not added to the Spike.

5. Total Recoverable Hydrocarbons - where reporting Spike & LCS data, a single spike of commercial Hydrocarbon products in the range of C12-C30 is added and it's Total Recovery is reported

in the C10-C14 cell of the Report.

6. pH and Free Chlorine analysed in the laboratory - Analysis on this test must begin within 30 minutes of sampling.Therefore laboratory analysis is unlikely to be completed within holding time.

Analysis will begin as soon as possible after sample receipt.

7. Recovery Data (Spikes & Surrogates) - where chromatographic interference does not allow the determination of Recovery the term "INT" appears against that analyte.

8. Polychlorinated Biphenyls are spiked only using Aroclor 1260 in Matrix Spikes and LCS.

9. For Matrix Spikes and LCS results a dash " -" in the report means that the specific analyte was not added to the QC sample.

10. Duplicate RPDs are calculated from raw analytical data thus it is possible to have two sets of data.

Qualifier Codes/Comments

Code Description

N01F2 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).

N02

Where we have reported both volatile (P&T GCMS) and semivolatile (GCMS) naphthalene data, results may not be identical. Provided correct sample handling protocols havebeen followed, any observed differences in results are likely to be due to procedural differences within each methodology. Results determined by both techniques have passedall QAQC acceptance criteria, and are entirely technically valid.

N04F1 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 BTEXanalytes. The "C6-C10" value is obtained by quantitating against a standard of mixed aromatic/aliphatic analytes.

N07Please note:- These two PAH isomers closely co-elute using the most contemporary analytical methods and both the reported concentration (and the TEQ) apply specifically tothe total of the two co-eluting PAHs

Item Description/Detail

Geology and soil landscapes The Penrith 1:100,000 Geological Series Sheet 9030 (1991)

indicates that Lots 36 and 37 are underlain by

Quaternary formations comprised of fine-grained sand,

silt and clay, while Lot 38 is underlain by Bringelly Shale

which comprises shale, carbonaceous claystone,

claystone, laminite, fine to medium grained lithic

sandstone and rare coal/tuff.

The Penrith 1:100,000 Soil Landscape Series Sheet (1989)

indicates that Lots 36 and 37 site soils comprise the South

Creek soil landscapes consisting of deep layered

sediments over bedrock or relict soils, and red and

yellow podzolic soils with areas of structured clays,

leached clay and yellow podzolic soils. The Blacktown

soil landscape is found on Lot 38 which consists of

shallow to moderately deep (<1 m) hard setting mottled

texture contrast soils, red and brown podzolic soils on

crests grading to yellow podzic soils on lower slopes and

in drainage lines.

Environmental receptors The site generally drains toward the dams on Lots 36 and

37 and to First Ponds Creek (north eastern corner of Lot

36 and adjoining property to east). First Ponds Creek is a

tributary of the Nepean River (more than 11 km to the

north).

Human receptors Existing surrounding rural residential developments.

Future residents and site workers / builders.

2.2 Hydrogeology

Review of NSW Natural Resources Atlas indicated two groundwater

bores (with available information) exist within approximately 1.5 km of

the site (Table 2).

Information in Table 2 indicates groundwater in the is used for

monitoring and domestic stock, and the water level is greater than 4.5

m below ground level (BGL). Groundwater levels are unlikely to be

indicative of the subject site as site elevation and topographic units

differ. Further investigation would be required to characterise site

hydrogeology.

Geotechnical investigations up to 4.0 mBGL did not encounter

groundwater (MA, 2014b), which is consistent with other sites MA has

investigated in nearby areas.

3 Preliminary Conceptual Site Model

3.1 Overview

This preliminary conceptual site model (CSM) has been developed

based on information documented in Stage 1 ESA (MA, 2014a).

3.2 Summary of Stage 1 ESA Findings

o The site land use has been rural residential since at least 1965.

Market gardens existed on Lot 36 since at least 1978 and

discontinued sometime before 1998. Market gardens are

currently in use on Lot 37 and have existed since at least 1998.

o A site walkover of Lot 36 found a single storey brick and tile

dwelling with one small and one large metal shed located to the

east of the dwelling. Access to sheds was unable to be

obtained, likely used for storage purposes. A metal shed pump

house on bare earth is located along western lot boundary, to

south of dam. Two stockpiles, located south of dam and north of

pump house, consist of plastics, fuel and oil containers, and

other containers of unknown content, old furniture, general

refuse, bricks, metal and PACM sheets. Former market gardens

located near western lot boundary and orchards near eastern

lot boundary, currently extensive weeds and overgrown

vegetation to north of dwelling.

o A site walkover of Lot 37 found a two storey brick and tile

dwelling and metal sheds to north of dwelling. Access to large

metal shed was unable to be obtained. Metal shed near

western boundary contains stock feed, styrofoam containers,

and general storage. Various stockpiles are located near the

sheds consisting of metal, timber, sandstone blocks, old vehicles,

building materials, concrete pads, plastic, fuel and oil

containers, 44 gallon drums, old car batteries, containers of

unknown content, PACM pipes and general rubbish. Oil staining

observed near stockpile of fuel and oil containers, and other

containers of unknown substance next to metal shed near

western lot boundary. Market gardens are located to east of

dwelling/sheds, near eastern lot boundary.

o A site walkover of Lot 38 found a weatherboard (PACM) clad

residential dwelling in south western corner of lot with metal roof

in serviceable condition. To north of weatherboard dwelling a

single storey brick and tile residential dwelling is located near

martens

Page 12

western lot boundary. A large metal shed is located between

brick and weatherboard dwellings. A smaller shed is located

near the western lot boundary to the north of brick dwelling,

containing stockpiles of metal sheeting, building materials and

timber.

3.3 Areas of Environmental Concern (AEC) and Contaminants of Primary Concern (COPC) Assessed During Stage 2 Works

3.4 Sensitive Receptors and Exposure Pathways

Table 4 provides a summary of identified sensitive receptors and

potential exposure pathways connecting receptors to identified

AEC/COPC outlined in Table 4.

Table 4: Summary of receptors and potential pathways.

Receptor Pathway

Human Receptors:

o Future site occupants.

o Site visitors.

o Site workers during any future

construction works.

o Surrounding offsite occupants.

o Dermal contact.

o Ingestion of potentially contaminated

soil.

o Inhalation of airborne contaminants.

o Migration of pollutants via site surface

and groundwaters.

Environmental Receptors

o First Ponds Creek

o Existing vegetated areas across the

site.

o Vegetated or landscaped areas of

any future site design plans.

o Migration of contaminated runoff.

o Direct contact of soil with site flora.

3.5 Data Gaps

Based on identified AECs, COPC and potential pathways to receptors,

intrusive investigations were recommended to characterise potential

adverse human and environmental risks which may impact the

proposed development.

4 Field and Laboratory Investigations

4.1 Field Programme overview

Referencing the preliminary CSM (Section 3), a soil investigation

program was planned to:

o Investigate the contamination status of areas associated with

previous and current agricultural chemical (OC/OP pesticide

and heavy metal) use being former and current market gardens

and orchards.

o Investigate identified potential hotspot areas of contamination

(i.e. soil stains, structures and stockpiles).

4.2 Investigation Constraints

Site investigation constraints included:

o Limited access inside/beneath existing dwellings.

o Limited access inside/beneath existing sheds.

o No access to sediment in base of dams due to water present.

To fully assess site contamination status and address data gaps in the

CSM, further soil investigation will be required following demolition of

structures and dewatering of dams.

4.3 Intrusive Investigation Methodology

An overview of site investigation methodology is provided in Table 5. A

description of hotspot/stockpile sampling is provided in Table 6.

The soil sampling programme for former/current market gardens and

orchards was designed in general accordance with NSW EPA (1995)

guidelines, with sampling targeting AECs identified in the Stage 1

assessment (MA, 2014a).

Site sampling locations are presented in Figures 1, 2 and 3, Attachment

A.

4.4 Sampling Methodology and Quality Assurance / Quality Control

Surface soil samples were collected just below the surface using a

spade. Stockpile/hotspot samples were generally collected from the

middle of the stockpile or observed stained area.

Soil sampling methodology (Table 7) was completed to meet data

quality objectives.

Table 7: Soil sampling methodology.

Activity Detail / Comments

Soil Sampling Soil sampling was completed by the supervising environmental engineer

from MA.

Each sample was placed into a laboratory-supplied, acid-rinsed 250mL

glass jar, labelled with a unique identification number and no

headspace to limit volatile loss. A clean pair of disposable gloves was

used when handling each sample.

Sample

Compositing Soil samples collected from former market garden and orchard areas

were combined to form 11 triple composite samples. Sample

compositing was completed by Envirolab Pty Ltd a NATA accredited

laboratory at the direction of MA.

Soil Screening An assessment of VOC compounds with a PID was outside the scope of

works

QA / QC Sampling Duplicate samples were collected at a rate of approximately 1 in 10

samples for intra-laboratory analysis.

Sample handling

and transportation

Sample collection, storage and transport were conducted according to

Collected samples were placed into an ice chilled cooler-box.

Samples were dispatched to NATA-accredited laboratories under chain

of custody documentation within holding times.

Decontamination of

sampling equipment

Where required, hand sampling equipment was decontaminated

between sampling locations by pressurised water spray with a solution

of Decon-90™, a phosphate-free detergent, followed by rinsing with

potable water.

A review of QA/QC procedure has been completed and is presented

in the data validation report (Attachment D). The report concludes that

data is suitable for the purposes of the assessment.

5 Assessment Criteria

5.1 Overview

The site assessment criteria (SAC) adopted for this ESA has been

derived from the following sources:

o ASC NEPM (1999, amended 2013) National Environmental

Protection (Assessment of Site Contamination) Measure (NEPM).

o Friebel & Nadebaum (2011) HSL for petroleum hydrocarbons in

soil and groundwater, part 1 technical development document

Guideline values for individual contaminants analysed for this

assessment are presented in laboratory tables in Attachment B.

Table 9 summarises the applicability of the SAC adopted for this

investigation.

Table 9: Summary of SAC.

SAC Applicability

Health investigation levels (HIL) Based on the proposed residential site use, HIL – A

Residential with soil access (ASC NEPM 1999, amended

2013) have been adopted.

Health screening levels (HSL) for

petroleum hydrocarbons

HSLs A – low density residential for sand (ASC NEPM

1999, amended 2013) have been adopted. Sand has

been selected as it provides the most conservative

screening level values. Soils sampled from stockpiles

and hotspot locations consisted of silty sands and topsoil

material.

Soil HSL provide a preliminary assessment of human risk

via inhalation of vapours from potential contamination.

For this purpose HSL A criteria are considered

appropriate.

Direct contact petroleum

hydrocarbon HSL

Direct contact HSL have been adopted from Friebel &

Nadebaum (2011) and provide assessment criteria for

human health risk where direct contact with TPH

contaminated soil is likely.

SAC Applicability

Ecological assessment criteria (EAS) A preliminary assessment of ecological risk has been

undertaken with reference to ecological screening

levels (ESL).

ESL apply principally to contamination contained in the

top 2m of soil.

ESLs for course grained soils in urban residential and

open spaces (ASC NEPM 1999, amended 2013) have

been adopted as a conservative measure.

Asbestos in soil/material Based on the preliminary nature of this assessment the

‘presence/absence’ of asbestos in soil/material has

been adopted as the SAC.

7 Discussion

7.1 Soil Contamination

A summary of identified soil contamination is as follows:

o Lead was detected at the adopted HSL (300 mg/kg) in sample

4469/HS12 (300 mg/kg).

o F2 – C10 – C16 was detected over the adopted HSL (110 mg/kg) in

samples 4469/HS02 (500 mg/kg) and 4469/HS06 (330 mg/kg).

o F2 – C10 – C16 was detected over the adopted ESL (120 mg/kg) in

samples 4469/HS02 (500 mg/kg) and 4469/HS06 (330 mg/kg).

o F3 – C16 – C34 was detected over the adopted ESL (1,300 mg/kg)

in samples 4469/HS02 (4,100 mg/kg) and 4469/HS06 (25,000

mg/kg).

o F4 – C34 – C40 was detected above the adopted ESL (5,600

mg/kg) in sample 4469/HS06 (10,000 mg/kg).

o F3 – C16 – C34 was detected over the adopted direct contact

(4,500 mg/kg) in sample 4469/HS06 (25,000 mg/kg).

o F4 – C34 – C40 was detected above the adopted direct contact

(6,300 mg/kg) in sample 4469/HS06 (10,000 mg/kg).

Soil sample 4469/HS02 was collected beneath a tractor stored beneath

a carport. Hydrocarbon factions (F2) exceeding HSL and hydrocarbon

fractions (F3 and F4) exceeding ESL are likely due to oil leaking from the

tractor onto the soil below.

Soil sample 4469/HS06 was collected from the centre of an observed

soil stain located near 44 gallon drums, motor oil containers and car

batteries. Typical carbon number chain lengths for motors oils range

from C15 – C30 (ATSDR, 1999) which correlates which the hydrocarbon

fractions (F2, F3 and F4) exceeding adopted SAC.

Soil sample 4469/HS12 was detected at the adopted HIL for lead.

Sample was collected from a builder’s waste stockpile containing

bricks, concrete, metals and terracotta pipe.

7.2 Material Contamination

ACM was identified at one location (ASB1) in the form of a fibre

cement sheeting fragment. ACM sampling location is provided on the

sampling plan in Attachment A.

8 Conclusions and Recommendations

Identified SAC exceedances and the positive identification of ACM

cement fibre sheeting identify risks to human and environmental

receptors identified in the preliminary CSM. A remediation action plan

(RAP) will be required to address these contamination risks and site

remediation is required prior to residential development and use.

The vertical extent of identified contamination at hotspot locations

HS02, HS06 and HS12 has not been defined and will require additional

soil testing involving boreholes/test pits. Results of soil sampling

conducted across former market garden/orchard areas indicates that

this use has not resulted in widespread present day contamination.

It is recommended that following demolition of existing site structures

(dwellings and sheds), draining of site dams and removal of identified

non soil stockpile waste (builder’s rubble, demolition waste etc.), that

additional soil testing (including at hotspot locations HS02, HS06 and

HS12) be conducted and an amendment to this report be prepared to

address identified investigation constraints (Section 4.2) and data gaps

within the CSM.

We consider that the site can be made suitable for proposed

residential development provided that a RAP is developed and

implemented accordingly. A likely remediation strategy would involve

offsite disposal of soils and material stockpiles, ACM and excavation

and offsite disposal of identified soil staining. Following remediation

works, a validation report is required to be prepared to confirm site

suitability for the proposed development.

Prior to any soil or ACM material being removed from site, a formal

waste classification assessment in accordance with NSW DECCW

Waste Classification Guidelines (2009) is required.

9 Limitations

This Stage 2 contamination assessment was undertaken in accordance

with current industry standards.

It is important to note that no land contamination study can be

considered to be a complete and exhaustive characterisation of a site

nor can it be guaranteed that any assessment shall identify and

characterise all areas of potential contamination or all past potentially

contaminating land-uses. This is particularly the case where areas of

the site are covered by structures and stockpiles. Therefore, this report

should not be read as a guarantee that only contamination identified

shall be found on the site. Should material be exposed in future which

appears to be contaminated, additional testing may be required to

determine the implications for the site.

Martens & Associates Pty Ltd has undertaken this assessment for the

purposes of assessing potential site contamination. No reliance on this

report should be made for any other investigation or proposal. Martens

& Associates accepts no responsibility, and provides no guarantee

regarding the characteristics of areas of the site not specifically studied

in this investigation.

Report Comments:Total Recoverable Hydrocarbons in soil:

# Percent recovery is not possible to report as the high concentration of analytes in the sample/s

have caused interference.

Asbestos: A portion of the supplied sample was sub-sampled for asbestos analysis according to Envirolab procedures.

We cannot guarantee that this sub-sample is indicative of the entire sample. Envirolab recommends supplying

40-50g of sample in its own container.

Asbestos ID was analysed by Approved Identifier: Lulu Guo, Paul Ching

Asbestos ID was authorised by Approved Signatory: Paul Ching

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

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

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


Revision No: R 00


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

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

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

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

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

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

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

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

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

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

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

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

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

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

generally extracted during sample extraction.

Spikes for Physical and Aggregate Tests are not applicable.

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

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

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

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

In circumstances where no duplicate and/or sample spike has been reported at 1 in 10 and/or

1 in 20 samples respectively, the sample volume submitted was insufficient in order to satisfy

laboratory QA/QC protocols.

When samples are received where certain analytes are outside of recommended technical

holding times (THTs), the analysis has proceeded. Where analytes are on the verge

of breaching THTs, every effort will be made to analyse within the THT

or as soon as practicable.
