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

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
57, 51 and 45 Gordon Road Schofields NSW NE120

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.

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.
57, 51 and 45 Gordon Road Schofields NSW NE120

Total Recoverable Hydrocarbons - 2013 NEPM Fractions
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

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.
57, 51 and 45 Gordon Road Schofields NSW NE120

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.

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.

QC - Acceptance Criteria
QC Data General Comments
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.

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.

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

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
Martens and Associates SOP.
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.
4.5 Laboratory Analytical Suite
Laboratory analysis was carried out by Envirolab Pty Ltd a NATA
accredited laboratory. Laboratory analytical documentation is
presented in Attachment C.
Site areas associated with former market garden and orchard use were
assessed by testing 2 discrete and 11 triple composite samples for
heavy metals and OC/OP pesticides. Hotspot/stockpile areas were

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.

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

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.
