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 iv 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.

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

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 2 315-335 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. The onsite dam links the Site with the neighbouring property east. Further east are similar East 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 3 315-335 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 5 315-335 Denham Court Road, Denham Court

3.0 DEVELOPMENT CONTROLS

3.1 Section 149 Certificate

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.

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 11 315-335 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 17 315-335 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 20 315-335 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 21 315-335 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 22 315-335 Denham Court Road, Denham Court

7.8 Asbestos

The dwelling and adjacent shed to the east of number 315 was identified as potentially constructed with asbestos containing materials. All buildings were in good condition and only pose a risk of asbestos exposure if they require demolition.

Analysis of asbestos in soils was undertaken for four samples. Asbestos fines/fibrous asbestos (AF/FA) was not detected in any of the samples collected from the Site.

Project ID: DL3886 24 315-335 Denham Court Road, Denham Court

7.9 Water and Sediment Sampling Results

The dam water and sediment were sampled by DLA on the 4th August 2016. The water samples were collected from a water depth estimated to be approximately 0.5m, while sediment samples were collected from the banks of the dam.

Results are summarised in Table 7e below:

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.

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 27 315-335 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.

Project ID: DL3886 28 315-335 Denham Court Road, Denham Court

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.

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.

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 C – QUANLITY CONTROL / QUALITY ASSURANCE

Project ID: DL3886 315-335 Denham Court Road, Denham Court

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 4C 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.

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:
