EXECUTIVE SUMMARY
DLA Environmental Services (DLA) was engaged by Group Development Services Pty Ltd to conduct a
Preliminary Site Investigation (PSI) of the following area:
315-335 Denham Court Road, Denham Court, NSW 2565 (the Site).
The PSI was commissioned to serve as supporting documentation for the issue of a residential
redevelopment Development Approval (DA) Consent. The conditions require a comprehensive
environmental site assessment to be submitted to Council characterising potential contamination
and the Site, drawing conclusions on the suitability of the Site for its proposed land use and making
recommendations to enable such conclusions.
A historical Site land use and activity assessment was conducted on the Site. The surrounding land
use and previous owners included graizers and dairy farmers. Due to the low scale of production
activities that occurred on the Site contamination from previous site use was expected to be of
relatively low risk.
The results of the laboratory analysis reported no evidence of contamination of the subsurface of
the Site by asbestos, petroleum hydrocarbons, PAH, pesticides, PCBs or Heavy Metals Site. The
onsite dam was assessed as suitable for dewatering via application to land (i.e. irrigation), and
sediments contained within the dam are considered suitable for beneficial on-site reuse. A salinity
assessment indicated that the soils on-site have negligible salinity effects, while the results of an
aggressivity assessment indicated that the soils located on-site are expected to be non-aggressive
towards steel, with possible localised mild aggressivity towards.
As the intended development on Site includes rezoning the Site to several residential properties, no
irrigation or effluent disposal is likely to take place on Site. DLA is therefore of the opinion that a
Salinity Management Plan is not required.
The dwelling and adjacent shed to the east of number 315 was identified as potentially constructed
with asbestos containing materials. Building materials that are suspected to contain asbestos will
require removal by a WorkCover approved licensed contractor with an asbestos clearance required
after removal.
Project ID: DL3879 v 315-335 Denham Court Road, Denham Court
It is therefore the opinion of DLA that the Site assessment objectives of this report have been
achieved. The PSI concludes that the Site is considered suitable for the intended land use consistent
with NEPM (NEPC, 2013) Residential A – Residential with Garden / Accessible soil. The structures
identified as potentially containing asbestos will require removal by a WorkCover approved
contractor, disposal of material at a licenced facility and an asbestos clearance at the completion of
removal.

1.0 INTRODUCTION
1.1 General
DLA Environmental Services (DLA) was engaged by Group Development Services Pty Ltd to conduct a
Preliminary Site Investigation (PSI) of the following area:
315-335 Denham Court Road, Denham Court, NSW 2565 (the Site).
The PSI was commissioned to serve as supporting documentation for the issue of a residential
redevelopment Development Approval (DA) consent. The DA conditions require an environmental
site assessment to be submitted to Liverpool City Council characterising potential contamination at
the Site, drawing conclusions on the suitability of the Site for its proposed land use, and providing
recommendations for further investigation or remediation, if required.
1.2 Objectives
The project objectives of this PSI are to satisfy the general requirements of State Environmental
Planning Policy No.55 (SEPP 55) in accordance with Contaminated Sites: Guidelines for Consultants
Reporting on Contaminated Sites (NSW EPA, 2011). Specifically, this PSI will consider the potential
for suspected historical activities to have caused contamination at the Site and assess the suitability
of the land for future land use consistent with Residential A in the National Environment Protection
(Assessment of Site Contamination) Amendment Measure 2013 (No.1) (‘NEPM’, NEPC, 2013).
1.3 Scope of Works
To achieve these objectives, DLA carried out the following works:
Search and review of records and Site plans available locally and from State Regulatory
Authorities, including WorkCover, Department of Lands and NSW EPA;
Review of historical aerial photographs available from the Land Information Centre;
Review of environmental Site conditions including the geology and hydrogeology;
Provide a comprehensive overview of the Site’s past and current land uses and potential
contamination issues;
Limited and targeted soil sampling;
Provide a preliminary assessment of Site contamination (if any) and discuss the Site
condition and suitability in consideration of the proposed development scenario;
Consideration of potential Site contamination management requirements, if any; and,
Preparation of this PSI report in accordance with relevant EPA made or endorsed guidelines.
Project ID: DL3886 2 315-335 Denham Court Road, Denham Court
2.0 SITE DESCRIPTION
2.1 Site Identification
The Site identification details are summarised in Table 2a below:
Table 2a – Site Identification Summary
ITEMS DETAILS
Address 315-335 Denham Court Road, Denham Court, NSW 2565
Local Government Authority Liverpool City Council
Lot and Deposited Plan Lot 131 and 312 DP1137588
Development Controls Liverpool City Council Development Control Plan
Site Zonings E4 – Environmental Living
Current Use Rural Residential
Proposed Use Residential with gardens / accessible soil
Site Area (approx.) 39,240 m2 (3.9 ha)
Locality Map Refer to Figure 1 – Site Location
Site Survey Refer to Figure 2 – Site Survey
2.2 Proposed Development
Based on the information provided, it is understood that the Site will be redeveloped to provide 12
residential lots ranging from 2003m2 to 5481m2 with the average size of 2653m2. The proposed
development will include a public road on the eastern boundary and a cul-de-sac through the middle
of the Site spanning 16 meters in width.
Refer to Figure 3 – Development Layout Plan.
This development scenario is consistent with the definition of ‘Residential with gardens and
accessible soil’ provided in Schedule B7 of the NEPM (NEPC, 2013) for residential developed areas.
Project ID: DL3886 3 315-335 Denham Court Road, Denham Court
2.3 Boundaries and Surrounding Land Use
The boundary and surrounding landscape features of the Site are summarised in Table 2b below:
Table 2b – Boundaries and Surrounding Land Use
DIRECTION DETAILS
North The Sydney Water Supply Canal and Rural Residential properties.
South Undisturbed bushland and open grasslands possibly used for grazing.
East The onsite dam links the Site with the neighbouring property east. Further east are similar
rural residential properties.
West Residential redevelopment, with a road network and some vacant lots.
2.4 Site Geology and Soils
Review of the Geological Survey 1:100,000 map of Penrith Series 9030 indicates the underlying
bedrock consists of Bringelly shale of the Wianamatta Group consisting of shale, carbonaceous
claystone, claystone, laminate, fine to medium grained lithic sandstone, rare coal and tuff.
Review of the 1:100,000 Soil Landscape of Penrith map prepared by the Soil Conservation Services of
NSW indicates the underlying soil consists of Residual soil of the Blacktown Landscape Group which
is characterised by shallow to moderately deep hard setting clays with moderately reactive highly
plastic subsoils with poor drainage.
2.5 Site Topography
The elevation of the Site ranges from approximately 91m Australian Height Datum (AHD) in the
north east corner to 96m AHD in the south west corner with an overall gradient down towards the
north east. Site drainage is also towards the north east with three separate large dams present on
the property collecting surface runoff.
2.6 Acid Sulfate Soils
Review of the Acid Sulfate Soil Risk Map, Liverpool Environmental Plan 2008 indicated that there are
no known occurrences of acid sulfate soils in the area. No visual indications of acid sulfate soils were
observed during the investigation works.
Project ID: DL3886 4 315-335 Denham Court Road, Denham Court
2.7 Salinity and Aggressivity of Soils
The Salinity Potential in Western Sydney map (DIPNR, 2002) indicates the Site area generally is
within a region of moderate salinity potential with high and known salinity potential also indicated.
2.8 Hydrology and Hydrogeology
Topography, surface cover and geology control the hydrogeology of the Site. Due to the relatively
low permeability of the underlying subsurface, rainfall run-off infiltrating through the soil and
bedrock profiles is expected to be minimal. It is anticipated that the majority of rainfall runoff will
flow into the onsite dam and continue to the neighbouring dams to the north east.
Given the hydrology of the Site and surrounding area, groundwater underlying the Site is expected
to flow in a north-east direction towards Bonds Creek.
Our search of the NSW Department Infrastructure, Planning and Natural Resources groundwater
database for the region indicates there that are 11 registered groundwater bores within a 1.5km
radius of the Site. Based on the NSW Office of Water Works Summary Reports, DLA expects the
permanent groundwater table to be located at depth within the underlying bedrock (approximately
170 m below ground level (bgl); however, the Summary Reports also indicate that there is perched
groundwater located at depths between 6.0m and 9.9m bgl, likely to be associated with the soil /
shale interface.

Groundwater is not considered to be at risk of contamination as a result of Site activities and,
therefore, has not been investigated further in this assessment. Refer to Appendix D for
Groundwater Works Summary Reports.
2.9 Site Meteorology
The Bureau of Meteorology NSW gives the average annual rainfall for the Liverpool area at
800.1mm, with an annual daytime temperature range of 16.5° to 28.5°C, and an annual average
temperature of 24.1°C.
Project ID: DL3886 6 315-335 Denham Court Road, Denham Court

4.3 Heritage / Archaeological Items
A search of the Australian Heritage Trust database, NSW Heritage Inventory and Archaeological
maps provided Liverpool Local Environmental Plan 2008 (Amendment No 45) did not reveal any
heritage listed items at the Site.
4.4 Site History Summary
The earliest Site history records (1892) indicate the land has been privately owned, with graziers or
dairy farmers owning and/or leasing the land from 1914. From 1986 number 315 has been occupied
by a residence, with number 335 having a residence constructed in 2016.
The Site also has a significant easement for the gas main through the Site. The high pressure gas
main on the Site would place significant restrictions on the ability of excavation or heavy machinery
to be used onsite and make uncontrolled fill highly unlikely on the Site. There was also no historical
evidence of any filling or subsurface storage on the Site.
Historical hazardous building materials such as lead based paint, galvanised zinc and asbestos
containing materials (ACM) are likely to have been used within the construction of buildings on the
Site within the last 50 years, including the shed and residential development on number 315.
Therefore, heavy metals and asbestos are considered potentially to be present within near surface
soils on-site. There is also a risk of hydrocarbons to be present in the surface soils due to the
possible use of farm machinery during grazing practices.
Project ID: DL3886 11 315-335 Denham Court Road, Denham Court
5.0 SAMPLING AND ANALYSIS PLAN
5.1 Field Investigation Procedure
The likelihood of contamination was assessed by comparison of assessment results against NSW EPA
produced or endorsed criteria available at the time this report was published. Sampling was
performed on a judgemental basis and targeted areas identified as potential high risk for
contamination. The justification of the sampling point regime for the assessment was based on the
investigator’s knowledge, operational requirements, experience and history of the Site. All historical
investigations and anecdotal evidence supported the sampling approach adopted and provided for
samples to be collected in an unbiased manner. Field investigation comprised the following:
Inspection of the Site; and,
Collection of six targeted soil samples.
Refer to Figure 4 –Sampling Locations.
5.1.1 Soil Collection
Soil samples for chemical analyses were generally collected in accordance with the Sampling Design
Guidelines (NSW EPA, 1995), NEPM (NEPC, 2013) and AS4482.1-2005. Collected soil samples were
immediately transferred to sample containers of appropriate composition (glass jars for chemical
analysis, plastic bags for asbestos). Job number; sample identification number; sampler’s initials and
date of sampling were recorded on sample labels affixed to the sample containers.
Chemical samples were then placed immediately into a chilled esky to minimise the risk of loss of
potential volatile components. The samples were transported under standard DLA chain-of-custody
protocols to the NATA accredited laboratories – Envirolab Services Pty Ltd and Australian Safer
Environment & Technology Pty Ltd. All chemical samples were stored and transported at
temperatures below 4°C.
All samples were collected by DLA staff who are specifically trained in hazardous waste field
investigation techniques and health and safety procedures. All techniques used are specified in DLA
Field Manual for Contaminated Sites, which are based on methods specified by the United States
Environment Protection Agency (US EPA) and NEPM (NEPC, 2013).
Project ID: DL3886 12 315-335 Denham Court Road, Denham Court
5.2 Analytical Strategy
Samples were analysed for listed chemicals based on potential contamination in the area and to
allow for a preliminary assessment of all representative areas of the Site. Samples were analysed for
the following parameters:
5.2.1 Inorganic
Heavy metals: arsenic (As), cadmium (Cd), chromium (Cr), copper (Cu), lead (Pb), mercury
(Hg), nickel (Ni), and zinc (Zn);
Salinity, Chloride, Sulphate, CEC, EC, pH; and,
Asbestos.
5.2.2 Organic
Total Recoverable Hydrocarbons (TRH);
Monocyclic Aromatic Hydrocarbons (BTEX);
Volatile TRH (vTRH);
Organochlorine Pesticides (OCs);
Organophosphorus Pesticides (OPs);
Polycyclic Aromatic Hydrocarbons (PAHs); and,
Polychlorinated Biphenyls (PCBs).
No Photo Ionisation Detection (PID) assessments were undertaken as TRH analyses were performed
on all samples.
5.3 Data Quality Objectives
The NEPM (NEPC, 2013) and Australian Standard (AS) 4482.1-2005 recommend that data quality
objectives (DQOs) be implemented during the investigation of potentially contaminated sites. The
DQO process described in AS 4482.1-2005 Guide to the Investigation and Sampling of Sites with
Potentially Contaminated Soil Part 1: Non-Volatile and Semi-Volatile Compounds outlines seven
distinct steps to outline the project goals, decisions, constraints and an assessment of the project
uncertainties and how to address these when they arise. The DQOs have been summarised in the
Table 5a.

5.4 Assessment Criteria
The assessment criteria have been chosen in accordance with current Australian and NSW EPA
guidelines. The criteria provided are the most current and widely accepted for Tier 1 assessment of
land use suitability at present in Australia, and have generally been developed using a risk-based
approach.
5.4.1 Soil Criteria
Criteria from the NEPM (NEPC, 2013) Schedule B1 were utilised for this assessment. Soil Health
Screening Levels (HSLs) for vapour intrusion were used for volatile petroleum contaminants, whilst
the US EPA Regional Screening levels were cited to extrapolate criteria for volatile halogenated
compounds.
With regard to the vapour intrusion criteria, the NEPM (NEPC, 2013) provides Health Screening
Levels (HSLs), Ecological Screening Levels (ESLs) and Management Limits (MLs) for TRH fractions in
soil based on concerns regarding ecological impacts, inhalation of vapours and direct contact with
contaminant sources. The material type of ‘sand’ has been used as it offers to most similar
correlation to the condition of soils at the Site.

5.5 Salinity Assessment
The guidelines for the Salinity assessment are outlined in Department of Land and Water
Conservation – ‘Site Investigation for Urban Salinity 2002’ and Department of Conservation and Land
Management ‘A Guide for the Interpretation of Soil Test Results 1992’. The number of samples and
analysis are based upon the guidelines in the Site Investigations for Urban Salinity (DLWC, 2002) and
Western Sydney Salinity Code of Practice (WSROC, 2003).
The Salinity Potential in Western Sydney map (DIPNR, 2002) indicated the Site area is within a region
of moderate salinity potential with high and known salinity potential also indicated. Initial Site
Investigations for Open Space (1:25 000 scale) recommends six to eighteen samples per 1km2,
determined by the variation of soil characteristics on site, the proposed future land use and the
potential for development to disturb and mobilise any salt present in soils.
Project ID: DL3886 18 315-335 Denham Court Road, Denham Court
The Site is approximately 0.039km2 with little variation in the soil characteristics. Effluent disposal is
currently will take place on Site. DLA considers four samples appropriate in accordance with the Site
area, soil type and proposed land use.
The criteria for assessing soil salinity is based on Electrical Conductivity and is shown in Table 5g
below:
Table 5g – Electrical Conductivity Criteria for Soils
CLASS ECe (ds/m) COMMENTS
Non-Saline <2 Salinity effects mostly negligible
Slightly Saline 2-4 Yields of very sensitive crops may be affected
Moderately Saline 4-8 Yields of many crops may be affected
Very Saline 8-16 Only tolerant crops yield satisfactorily
Highly Saline >16 Only a few very tolerant crops yield satisfactorily
Sodic soils are dispersible and are vulnerable to erosion and tunnelling. Sodicity is measured by
Exchangeable Sodium Percentage (ESP) and Cation Exchange Capacity (CEC). As soil salinity is a
function of soil stability and structure, parameters such as CEC, ESP and Sulphate must be
considered to provide a holistic understanding of potential degradation.
In addition to the above, the presence of sulphate and moderately acidic soils has the potential to
cause high soil aggressivity to concrete and steel structures, particularly if the structures are in direct
contact with the soil. The following sulphate measure of soil aggressivity is based on the criteria
outlined in the Australian Standard, AS 2159-2009 “Piling – Design and Installation” 2009 and are
summarized in Table 5h, 5i and 5j.

6.0 FIELD OBSERVATIONS
6.1 Site Inspection
Site inspections were conducted on the 1st of July 2016.
Number 335 comprises of a large open space of maintained lawn with some large trees to the east.
The dwelling on the Site is a recent addition and appears to be used as a display home. The property
has a bitumen driveway, with a small stockpile of surplus bitumen and some cut soils located east of
the dwelling.
The property on 315 has a driveway of recycled aggregate running through it with a storage area for
steel, machinery and demountable buildings along the north west boundary. A large metal shed on
a concrete slab is located in the middle of the property, with a small dwelling on the Site having an
easterly aspect. The dwelling has potentially been renovated with suspected modern fibre cement
cladding used rather than asbestos containing materials. It is unclear whether asbestos containing
materials are underlying the cladding or if asbestos containing materials are still present within the
house.
There is a small storage shed to the east of the dwelling which was observed to have asbestos
containing materials in the eaves of the shed. A larger tin shed on a concrete slab is located to the
west of the dwelling. Assess to the shed is via crushed aggregate with a path leading to a storage
area on the northern boundary of the Site. Materials stored include tyres, demountable buildings,
car bodies, trailers and truck bodies.
Along the north eastern boundary is a large dam spanning across the Site and into the neighbouring
property. Water in the dam comes from surface runoff from the Site, road and neighbouring
properties.
A large gas main dissects the properties in a south west to north east direction and is adjacent to the
Sydney water supply canal.
The soil profile across the Site was observed comprise brown moist clay loam topsoil (200mm thick)
overlying orange red medium plasticity residual clays.
6.2 Dangerous Goods
There were no dangerous goods or dangerous goods storage facilities observed on the Site.
Project ID: DL3886 21 315-335 Denham Court Road, Denham Court
6.3 Flora and Fauna
The majority of the Site is covered by established grasslands and some large trees. There are no
crops or plants currently grown on-site.
No significant or endangered animal species were observed on the Site. All trees and grass lands
appeared to be healthy and free of environmental stress.
6.4 Fill Material
Minor cut and fill activities are expected to have occurred over the Site to permit the level
installation of the dwellings and access paths. The observed stockpile of surplus clay to the west of
the driveway in number 315 was visually similar to the residual clays underlying the Site, indicating
excavation of the Site is likely to have occurred.
A small stockpile of bitumen was also observed on number 335 and is expected to be surplus from
the previously installed driveway. There was no identified fill material buried on the Site.
6.5 Offsite Observations
The neighbouring properties to the north and east are similar rural residential properties.
Residential redevelopment is currently occurring to the east of the Site, with a large area of open
space to the south. The Sydney Water supply canal is located adjacent to the north west boundary
of the Site.
Project ID: DL3886 22 315-335 Denham Court Road, Denham Court
7.0 RESULTS
The sampling regime involved the collection of six representative primary surface samples. Two
sediment samples were collected from the onsite dam for assessment for beneficial reuse on site as
well as two water samples from the onsite dam for dewatering applications. The results of the
assessments conducted at the Site are summarised below.
Refer to Appendix A – Data Summary Table and Appendix B – NATA Certified Analytical Results.
7.1 Monocyclic Aromatic Hydrocarbons, Volatile Total Recoverable Hydrocarbons
and Semi Volatile Total Recoverable Hydrocarbons
All primary soil and sediment samples were analysed for Volatile Total Recoverable Hydrocarbons
(vTRH) and Benzene, Toluene, Ethyl benzene, Xylene and Naphthalene (BTEX). There were no
concentrations of vTRH, BTEX or Naphthalene recorded above the laboratory Limit of Reporting
(LOR).
All samples were also analysed for semi-volatile Total Recoverable Hydrocarbon (TRH) compounds.
There were no concentrations of TRH reported above the laboratory LOR with the exception of TRH
F3 in sample S3 with a concentration of 110mg/kg which is below the site acceptance criteria.
7.2 Polycyclic Aromatic Hydrocarbons
All primary soil and sediment samples were analysed for Polycyclic Aromatic Hydrocarbons (PAH)
compounds. There were no reported detections of Benzo(a)Pyrene TEQ, however Total PAH was
detected above the laboratory LOR in sample S4 (0.15mg/kg). All concentrations were below the
adopted assessment criteria of 300mg/kg.
7.3 Pesticides and Polychlorinated Biphenyls
Three primary samples and the two dam sediment samples were analysed for Organochlorine (OC),
Organophosphate (OP) pesticides and Polychlorinated Biphenyls (PCBs). There were no
concentrations of OC or OP pesticides or PCBs reported above the Laboratory LOR.
7.4 Heavy Metals
All soil samples from the Site were analysed for all eight heavy metals. Detections were reported for
all heavy metals with the exception of mercury. All concentrations were below the HILs.
Project ID: DL3886 23 315-335 Denham Court Road, Denham Court

Bold denotes exceedance of reuse or discharge criteria.
The two water samples collected from the dam reported Total Nitrogen and copper exceeding the
nominated offsite discharge criteria. All criteria met the required onsite reuse/irrigation
requirements.
The two sediment samples collected from the dam reported contaminant concentrations less than
the adopted soil guidelines, therefore indicating that the sediments within the dam would be
suitable for onsite reuse.

7.10 QA/QC Comments
Field quality assurance/quality control (QA/QC) included calculation of the relative percent
difference (%RPD).
An intra-laboratory duplicate rate of 16.7% was achieved, greater than the 10% required by the Field
Quality Plan. The calculated %RPD results were reported to comply with the criteria set for
acceptable RPDs.
Refer to Appendix C – Quality Assurance and Quality Control.

8.0 DISCUSSION
The desktop study of the Site considered the available data on geology and groundwater, historical
titles, Dangerous Goods licences, aerial photographs and heritage searches, which is in accordance
with the Contaminated Sites: Guidelines for Consultants Reporting on Contaminated Sites (NSW EPA,
2011).
A Site investigation was conducted and found no evidence of surface staining, odours or visible
sources of contamination. The results of intrusive investigations carried out on-site reported
contaminant concentrations below the adopted site acceptance criteria.
The dwelling and adjacent shed within number 315 was identified as potentially constructed with
asbestos containing materials. Although all buildings were noted to be in good condition and were
not considered to pose a risk of asbestos exposure, it is understood the structures will require
demolition prior to redevelopment. Material that is suspected to contain asbestos will require
removal by a WorkCover approved licensed contractor, and a subsequent asbestos clearance
inspection.
The results of the salinity assessment undertaken on-site indicated salinity effects on the Site were
mostly negligible. The results of the aggressivity assessment indicated that the soils located on-site
are expected to be non-aggressive towards steel, with possible localised mild aggressivity towards
concrete. On average, the pH from the Site soils was mildly acidic. The Exchangeable Sodium
Percentage (ESP) of the soil samples ranged between non-sodic and sodic. The Cation Exchange
Capacity (CEC) of the samples were in the low range, with a single sample (SAL-3) found to be in the
moderate CEC range. The Electrical Conductivity for all soil samples were found to be in the non-
saline range, with salinity affects mostly negligible.
As the intended development on Site includes rezoning the Site to several residential properties, no
irrigation or effluent disposal is likely to take place on Site. DLA is therefore of the opinion that a
Salinity Management Plan is not required.
A dam water and sediment assessment was conducted to assess decommissioning options for the
dam and whether sediments were suitable for onsite beneficial reuse. The two collected water
samples from the Site identified concentrations of Total Nitrogen and copper exceeding the
nominated offsite discharge criteria. All concentrations met the required onsite reuse/irrigation
criteria. The two sediment samples collected from the Site complied with the onsite soil guidelines
which indicated that the sediments within the dam would be suitable for onsite reuse.
Project ID: DL3886 28 315-335 Denham Court Road, Denham Court
The desktop assessment, visual historical investigation and onsite inspections indicated that the
identified areas of environmental concern and potential sources of contamination have not resulted
in adverse impact to the subsurface of the Site.

9.0 CONCLUSIONS
The sampling regime and subsequent assessment and reporting of the Site are considered adequate
for the purpose of assessing the suitability of the Site for the proposed future land use in accordance
with The Hills Shire Council, relevant Development Consent Conditions and the general
requirements of State Environmental Planning Policy No.55 (SEPP 55). All reporting has been
undertaken in accordance with the Contaminated Sites: Guidelines for Consultants Reporting on
Contaminated Sites (NSW EPA, 2011) and the Guidelines for the NSW Site Auditor Scheme (NSW EPA,
2nd ed., 2006).
A historical Site land use and activity assessment was conducted on the Site. The surrounding land
use and previous owners included graziers and dairy farmers. Due to the low scale of production
activities that occurred on the Site contamination from previous site use was expected to be of
relatively low risk.
The results of the laboratory analysis reported no evidence of contamination of the subsurface of
the Site by asbestos, petroleum hydrocarbons, PAH, pesticides, PCBs or Heavy Metals Site. The
onsite dam was assessed as suitable for dewatering via application to land (i.e. irrigation), and
sediments contained within the dam are considered suitable for beneficial on-site reuse. A salinity
assessment indicated that the soils on-site have negligible salinity effects, while the results of an
aggressivity assessment indicated that the soils located on-site are expected to be non-aggressive
towards steel, with possible localised mild aggressivity towards.
As the intended development on Site includes rezoning the Site to several residential properties, no
irrigation or effluent disposal is likely to take place on Site. DLA is therefore of the opinion that a
Salinity Management Plan is not required.
The dwelling and adjacent shed to the east of number 315 was identified as potentially constructed
with asbestos containing materials. Building materials that are suspected to contain asbestos will
require removal by a WorkCover approved licensed contractor with an asbestos clearance required
after removal.
It is the opinion of DLA that the assessment objectives of this report have been achieved. The PSI
concludes that the Site is considered suitable for the intended land use consistent with NEPM (NEPC,
2013) Residential A – Residential with Garden / Accessible soil. The structures identified as
potentially containing asbestos will require removal by a WorkCover approved contractor, disposal
of material at a licenced facility and an asbestos clearance at the completion of removal.

Method ID Methodology Summary
Org-016 Soil samples are extracted with methanol and spiked into water prior to analysing by purge and trap GC-MS.
Water samples are analysed directly by purge and trap GC-MS. F1 = (C6-C10)-BTEX as per NEPM B1
Guideline on Investigation Levels for Soil and Groundwater.
Org-014 Soil samples are extracted with methanol and spiked into water prior to analysing by purge and trap GC-MS.
Org-003 Soil samples are extracted with Dichloromethane/Acetone and waters with Dichloromethane and analysed by
GC-FID.
F2 = (>C10-C16)-Naphthalene as per NEPM B1 Guideline on Investigation Levels for Soil and Groundwater
(HSLs Tables 1A (3, 4)). Note Naphthalene is determined from the VOC analysis.
Org-012 Soil samples are extracted with Dichloromethane/Acetone and waters with Dichloromethane and analysed by
GC-MS. Benzo(a)pyrene TEQ as per NEPM B1 Guideline on Investigation Levels for Soil and Groundwater -
2013.
For soil results:-
1. ‘TEQ PQL’ values are assuming all contributing PAHs reported as <PQL are actually at the PQL. This is the
most conservative approach and can give false positive TEQs given that PAHs that contribute to the TEQ
calculation may not be present.
2. ‘TEQ zero’ values are assuming all contributing PAHs reported as <PQL are zero. This is the least
conservative approach and is more susceptible to false negative TEQs when PAHs that contribute to the TEQ
calculation are present but below PQL.
3. ‘TEQ half PQL’ values are assuming all contributing PAHs reported as <PQL are half the stipulated PQL.
Hence a mid-point between the most and least conservative approaches above.
Note, the Total +ve PAHs PQL is reflective of the lowest individual PQL and is therefore" Total +ve PAHs" is
simply a sum of the positive individual PAHs.
Org-005 Soil samples are extracted with dichloromethane/acetone and waters with dichloromethane and analysed by
GC with dual ECD's.
Org-008 Soil samples are extracted with dichloromethane/acetone and waters with dichloromethane and analysed by
GC with dual ECD's.

Quality Control Definitions
Blank: 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 Criteria
Duplicate 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 (+/-50% surrogates) and 10-140% for labile SVOCs (including labile surrogates), ultra trace organics
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.
Where sampling dates are not provided, Envirolab are not in a position to comment on the validity
of the analysis where recommended technical holding times may have been breached.

APPENDIX C1 – FIELD QUALITY CONTROL
During the assessment of contaminated sites, the integrity of data collected is considered
paramount. With the assessment of the Site, a number of measures were taken to ensure the quality
of the data. These included:
Sample Containers
Soil samples collected during the investigation were placed immediately into laboratory prepared
glass jars with Teflon lid inserts. Standard identification labels were adhered to each individual
container and labelled according to depth, date, sampling team and media collected.
Decontamination
All equipment used in the sampling program which includes a hand auger, spades and mixing bowl
was decontaminated prior to use and between samples to prevent cross contamination.
Decontamination of equipment involved the following procedures:
Cleaning equipment in potable water to remove gross contamination;
Cleaning in a solution of Decon 90; and,
Rinsing in clean demineralised water then wiping with clean lint free cloths.
Sample Tracking, Identification and Holding Times
All samples were forwarded to Envirolab Services and SGS Australia under recognised chain of
custodies with clear identification outlining the date, location, sampler and sample ID. All samples
were recorded by the laboratory as meeting their respective holding times. The sample tracking
system is considered adequate for the purposes of sample collection.
Sample Transport
All samples were packed into an esky with ice from the time of collection. These were transported
under chain of custody from the site to Envirolab Services Pty Ltd, NATA registered laboratories
located in Chatswood and Alexandria respectively. During the project, the laboratory reported that
all the samples arrived intact and were analysed within holding times for the respective analytes.
Samples were kept below 4C at all times.
Project ID: DL3886 315-335 Denham Court Road, Denham Court
Field Duplicate Samples
Field duplicate samples for soil were prepared in the field through the following process:
A larger than normal quantity of soil is recovered from the sample location selected for
duplication;
The sample is placed in a decontaminated stainless bowl and mixed as thoroughly as
practicable before being divided into equal parts;
Two portions of the sub-sample are immediately transferred, one for an intra-laboratory
duplicate and another as a sample; and,
Samples are placed into a labelled, laboratory supplied 250ml glass jar and sealed with an
airtight, Teflon screw top lid. The fully filled jars are labelled as the sample and duplicate and
immediately placed in a chilled esky.
Duplicate samples were prepared on the basis of sample numbers recovered during the field work.
The duplicate sample frequency was computed using the total number of samples analysed as part
of this assessment. The duplicate sample frequencies are shown below:
SOIL SAMPLES 6 Samples 1 intra-laboratory duplicate – 16.7%
An intra-laboratory duplicate rate of 16.7% was achieved, above the 10% required by the Field
Quality Plan.
Comparisons were made of the laboratory test results for the duplicate samples with the original
samples and the Relative Percentage Difference (RPD) calculated as difference / average in order to
assess the accuracy of the sampling and laboratory test procedures. The comparisons between the
duplicates and original samples indicate acceptable RPDs when they comply with criteria which are
commonly set at:
Less than 30% for inorganics and 50% for organics;
Less than five times the Laboratory LOR; and,
The difference between concentrations is less than 5% of the relevant HIL concentration.
Table C1 provides details of intra-laboratory chemical duplicates.

Field duplicates provide an indication of the whole validation process, including the sampling
process, sample preparation and analysis. A single metal for the intra laboratory duplicate exceeded
the DQO of 30%. The differences in concentration of arsenic in the intra-laboratory duplicate pair
was reported as less than five times the LOR.
The results therefore meet the nominated DQOs.
Project ID: DL3886 315-335 Denham Court Road, Denham Court
APPENDIX C2 – LABORATORY ANALYTICAL AND QUALITY PLAN
The integrity of analytical data provides the second step in the QA/QC process for total data
compliance. The data validation techniques adopted by DLA are based upon techniques published by
the USEPA and in line with methods and guidelines adopted by the NSW EPA and outlined in the
NEPM (NEPC, 2013). Descriptions are provided of the specific mechanisms used in the assessment of
accuracy, precision and useability of analytical data within the project.
Blanks
Blanks were used for the identification of false positive data. Laboratory blank samples were
analysed. No cross contamination of samples is said to have occurred as a result of laboratory
techniques provided all blanks show concentrations below the levels of detection. No results on
blank samples were above the level of reporting for any determination during the project.
Spikes and Control Samples
Control sample spikes were utilised for determination of matrix recovery analysis. This involves
analysis of spiked control samples and their duplicates, spiked with a known concentration of
relative analyte. Accuracy was assessed by calculation of the percent recovery (%R). The duplicate
sample spikes were used to assess the precision of the methods used. The recoveries for all matrix
spike analysis were within the acceptance criteria of 60-140%.
Duplicates
Laboratory Duplicates are tested to ensure the results meet the requirements of QA/QC. The %RPD
for the majority of the intra-laboratory and inter-laboratory duplicates had concentrations that
complied with the criteria set for acceptable RPDs. Where deviation from the parameters set for
RDPs were noted, the effects on the sampling methods and accuracy were not deemed significant.
Surrogates
To assess the performance of individual organic analysis the laboratory used surrogates. Recoveries
were calculated for each surrogate providing an indication of analytical accuracy. Surrogate
recoveries for soil samples were all within recommended control limits, indicating that there was an
acceptable degree of accuracy in analysing for organic compounds.
Laboratory Detection Limits
Laboratory detection limits for soil and water analyses by Envirolab and SGS are outlined in Table
C25 and Table C6 C3 below:
