1. INTRODUCTION

1.1 BACKGROUND

Raw Earth Environmental Pty Ltd (Raw Earth) were engaged to conduct a Salinity & Aggressivity

Assessment (SAA) for the property located at 291 Flushcombe Road, Blacktown NSW 2148 (the site).

As shown in Figure 1, the site is located approximately 29.5km west of the Sydney Central Business

District, within the Local Government Area of Blacktown City Council.

The site covers an approximate area of 1,800m2 (as shown in Figure 2) and is identified as Lot 1 DP

871994. The site is currently occupied by one residential single-storey dwelling with a detached

garage and an associated driveway, one small storage shed, one large storage shed, one underground

septic tank and one telecommunications services pit located in the north-western portion of the site.

On-site vegetation showed no signs of decay and/or stress.

1.2 PROPOSED DEVELOPMENT

Raw Earth understand that site is proposed to be redeveloped to allow for the development of a

childcare center which may involve the following works:

● Tree removal and demolition of existing structures; and

● Civil works including construction of new structures and playgrounds.

2.2 SITE DESCRIPTION

A qualified Environmental Scientist inspected the site on 13th October 2020. Observations noted

during the inspection are summarised below.

At the time of the site inspection, the site contained the following structures and features:

• The site consisted of a single-storey residential dwelling with one small, and one large shed,

and one chicken shed along the western boundary portion of the site;

• An underground septic tank was also found attached to the residential dwelling, off the

western portion of the main dwelling;

• Potential Asbestos Containing Material (ACM) was suspected being present within the fabric

of on-site structures, including the main dwelling and backyard sheds;

• Flaking paint was identified on external wall surfaces of on-site structures and could contain

lead due to the age of the structures;

• Grass and vegetation which displayed no sign of stress covered most external ground

surfaces with exceptions of the footprints of on-site structures and the concrete driveway in

the south- eastern corner of the site;

• One telecommunications services pit was found located in the front yard (eastern portion);

and



• There was no evidence of other underground storage tanks, and/or chemical/ fuel storage on

site.

3. FIELDWORK & LABORATORY ANALYSIS

A site inspection and soil sampling program was undertaken on 13th October 2020. Hand auger

excavation of 6 boreholes spread across accessible areas of the site to collect an even distribution of

samples representative of site conditions. Samples were collected from a maximum depth of 0.4m

below ground surface (mbgl) or prior refusal.

Laboratory analysis of samples collected from the site by a National Association of Testing Authorities

(NATA) accredited laboratory.

Soil samples were collected directly from the auger, placed in laboratory prepared 250mL soil jars,

labelled, and placed on ice in an esky for transport under chain of custody (COC) to a NATA accredited

laboratory for the analysis of the COPC. The hand auger was decontaminated between each borehole

excavation with Decon90.



4. SUBSURFACE CONDITIONS

Subsurface conditions across the site as observed during borehole excavations were generally silty

topsoil underlain by a silty clay, brown with pale brown/ orange mottle, humid to moist, medium to

low plasticity. Borehole locations are referenced in Figure 2.

No groundwater was encountered during the investigation. This is due to the shallow excavation of

boreholes. Groundwater may present at the site at an increased depth.

7. CONCLUSIONS

The property located at 291 Flushcombe Road, Blacktown NSW 2148 (‘the site’) was the subject of a

Salinity & Aggressivity Assessment.

The salinity assessment found site conditions to be Non-saline.

The aggressivity assessment indicates the following:

- Steel in low and high permeability soils were found to be Non-aggressive;

- Concrete in low permeability soils were found to be non-aggressive to mild; and



- Concrete in high permeability soils were found to be mild to moderate.

It is recommended appropriate foundation design and construction should be further investigated by

a Geotechnical Engineer and/or Structural Engineer prior to the design and construction stage of any

new proposed development to identify and confirm a suitable foundation system.



8. LIMITATIONS

Raw Earth Environmental Pty Ltd (Raw Earth) understands to the best of our knowledge, the

information within this report is accurate at the date of issue. However, due to the irregularity and

dynamic nature of subsurface conditions, soil and groundwater characteristics are capable of change

over a short period of time. No warranties, expressed or implied, are made. The contents of this report

must be read in full.

Subsurface conditions across a site cannot be fully defined by an investigation. Soil and/or

groundwater samples were analysed for common contaminants and/or indicators of contamination

only. Sample analytical results obtained during the investigation may not be representative of the

extremes of contamination which could be present at the site. Therefore, there is not guarantee that

other toxic compounds and/or hazardous materials do not exist within the site.

If the unexpected finds of materials suspected to be hazardous or toxic occur, all site works must

cease, and Raw Earth must be immediately contacted for further instruction.

Raw Earth performed the services in a manner consistent with the normal level of care and expertise

exercised by members of the environmental consulting profession. There is no investigation thorough

enough to dismiss a particular material, which presently or in the future is considered hazardous at

the site. Regulatory criteria are subject to change, where concentrations of a particular contaminant

currently considered low, could be subject to review and fall under different regulatory standards and

criteria and may require remediation in the future.

The results of this assessment are based on the site conditions and regulatory criteria identified at the

time of the site inspection. Raw Earth will not be liable to revise the report to account for any changes

in site characteristics, regulatory requirements, assessment criteria or the availability of additional

information, subsequent to the issue date of this report. The scope and period of Raw Earths’ services

are subject to restrictions and limitations. Raw Earth did not perform a complete assessment of all

possible conditions that may exist at the site.



Raw Earth takes no responsibility or liability for errors in any data obtained from scientific laboratories,

regulatory agencies, statements from sources outside of Raw Earth, or developments resulting from

situations outside the scope of this project.

All conclusions and recommendations regarding the site are the opinion of Raw Earth. Opinions are

judgements, which are based on our understanding and interpretation of current regulatory standards

and should not be construed as legal opinions.

SE212211 R0QC SUMMARY

MB blank results are compared to the Limit of Reporting

LCS and MS spike recoveries are measured as the percentage of analyte recovered from the sample compared the the amount of analyte spiked into the sample.

DUP and MSD relative percent differences are measured against their original counterpart samples according to the formula : the absolute difference of the two results divided

by the average of the two results as a percentage. Where the DUP RPD is 'NA' , the results are less than the LOR and thus the RPD is not applicable.

METHOD METHODOLOGY SUMMARY

METHOD SUMMARY

The test is carried out by drying (at either 40°C or 105°C) a known mass of sample in a weighed evaporating basin.

After fully dry the sample is re-weighed. Samples such as sludge and sediment having high percentages of

moisture will take some time in a drying oven for complete removal of water.

AN002

pH in Soil Sludge Sediment and Water: pH is measured electrometrically using a combination electrode and is

calibrated against 3 buffers purchased commercially. For soils, sediments and sludges, an extract with water (or

0.01M CaCl2) is made at a ratio of 1:5 and the pH determined and reported on the extract. Reference APHA

4500-H+.

AN101

Conductivity and TDS by Calculation: Conductivity is measured by meter with temperature compensation and is

calibrated against a standard solution of potassium chloride. Conductivity is generally reported as µmhos/cm or

µS/cm @ 25°C. For soils, an extract of as received sample with water is made at a ratio of 1:5 and the EC

determined and reported on the extract, or calculated back to the as-received sample. Salinity can be estimated

from conductivity using a conversion factor, which for natural waters, is in the range 0.55 to 0.75. Reference APHA

2510 B.

AN106

Anions by Ion Chromatography: A water sample is injected into an eluent stream that passes through the ion

chromatographic system where the anions of interest ie Br, Cl, NO2, NO3 and SO4 are separated on their relative

affinities for the active sites on the column packing material . Changes to the conductivity and the UV-visible

absorbance of the eluent enable identification and quantitation of the anions based on their retention time and

peak height or area. APHA 4110 B

AN245


SE212211 R0

Unless it is reported that sampling has been performed by SGS, the samples have been analysed as received.

Solid samples expressed on a dry weight basis.

Where "Total" analyte groups are reported (for example, Total PAHs, Total OC Pesticides) the total will be calculated as the sum of the individual

analytes, with those analytes that are reported as <LOR being assumed to be zero. The summed (Total) limit of reporting is calcuated by summing

the individual analyte LORs and dividing by two. For example, where 16 individual analytes are being summed and each has an LOR of 0.1 mg/kg,

the "Totals" LOR will be 1.6 / 2 (0.8 mg/kg). Where only 2 analytes are being summed, the " Total" LOR will be the sum of those two LORs.

Some totals may not appear to add up because the total is rounded after adding up the raw values.

If reported, measurement uncertainty follow the ± sign after the analytical result and is expressed as the expanded uncertainty calculated using a

coverage factor of 2, providing a level of confidence of approximately 95%, unless stated otherwise in the comments section of this report.

Results reported for samples tested under test methods with codes starting with ARS -SOP, radionuclide or gross radioactivity concentrations are

expressed in becquerel (Bq) per unit of mass or volume or per wipe as stated on the report. Becquerel is the SI unit for activity and equals one

nuclear transformation per second.

Note that in terms of units of radioactivity:

a. 1 Bq is equivalent to 27 pCi

b. 37 MBq is equivalent to 1 mCi

For results reported for samples tested under test methods with codes starting with ARS -SOP, less than (<) values indicate the detection limit for

each radionuclide or parameter for the measurement system used. The respective detection limits have been calculated in accordance with ISO

11929.

SGS holding time criteria are drawn from current regulations and are highly dependent on sample container preservation as specified in the SGS “Field Sampling Guide for

Containers and Holding Time” (ref: GU-(AU)-ENV.001). Soil samples guidelines are derived from NEPM "Schedule B(3) Guideline on Laboratory Analysis of Potentially

Contaminated Soils". Water sample guidelines are derived from "AS/NZS 5667.1 : 1998 Water Quality - sampling part 1" and APHA "Standard Methods for the Examination

of Water and Wastewater" 21st edition 2005.

Extraction and analysis holding time due dates listed are calculated from the date sampled, although holding times may be extended after laboratory extraction for some

analytes. The due dates are the suggested dates that samples may be held before extraction or analysis and still be considered valid.

Extraction and analysis dates are shown in Green when within suggested criteria or Red with an appended dagger symbol (†) when outside suggested criteria. If the sampled

date is not supplied then compliance with criteria cannot be determined. If the received date is after one or both due dates then holding time will fail by default.

Surrogate results are evaluated against upper and lower limit criteria established in the SGS QA /QC plan (Ref: MP-(AU)-[ENV]QU-022). At least two of three routine level soil

sample surrogate spike recoveries for BTEX/VOC are to be within 70-130% where control charts have not been developed and within the established control limits for charted

surrogates. Matrix effects may void this as an acceptance criterion. Water sample surrogate spike recoveries are to be within 40-130%. The presence of emulsions,

surfactants and particulates may void this as an acceptance criterion.

Laboratory Control Standard (LCS) results are evaluated against an expected result, typically the concentration of analyte spiked into the control during the sample

preparation stage, producing a percentage recovery. The criteria applied to the percentage recovery is established in the SGS QA /QC plan (Ref: MP-(AU)-[ENV]QU-022). For

more information refer to the footnotes in the concluding page of this report.

Recovery is shown in Green when within suggested criteria or Red with an appended dagger symbol (†) when outside suggested criteria.

Matrix Spike (MS) results are evaluated as the percentage recovery of an expected result, typically the concentration of analyte spiked into a field sub -sample during the

sample preparation stage. The original sample 's result is subtracted from the sub-sample result before determining the percentage recovery. The criteria applied to the

percentage recovery is established in the SGS QA/QC plan (ref: MP-(AU)-[ENV]QU-022). For more information refer to the footnotes in the concluding page of this report.

Recovery is shown in Green when within suggested criteria or Red with an appended reason identifer when outside suggested criteria. Refer to the footnotes section at the

end of this report for failure reasons.

MATRIX SPIKES

No matrix spikes were required for this job.

Matrix spike duplicates are calculated as Relative Percent Difference (RPD) using the formula: RPD = | OriginalResult - ReplicateResult | x 100 / Mean

The original result is the analyte concentration of the matrix spike. The Duplicate result is the analyte concentration of the matrix spike duplicate.

The RPD is evaluated against the Maximum Allowable Difference (MAD) criteria and can be graphically represented by a curve calculated from the Statistical Detection Limit (SDL) and Limiting Repeatability (LR) using the formula: MAD = 100 x SDL / Mean + LR

Where the Maximum Allowable Difference evaluates to a number larger than 200 it is displayed as 200.

RPD is shown in Green when within suggested criteria or Red with an appended reason identifer when outside suggested criteria. Refer to the footnotes section at the end of this report for failure reasons.

① At least 2 of 3 surrogates are within acceptance criteria.

② RPD failed acceptance criteria due to sample heterogeneity.

③ Results less than 5 times LOR preclude acceptance criteria for RPD.

④ Recovery failed acceptance criteria due to matrix interference.

⑤ Recovery failed acceptance criteria due to the presence of significant concentration of analyte (i.e. the

concentration of analyte exceeds the spike level).

⑥ LOR was raised due to sample matrix interference.

⑦ LOR was raised due to dilution of significantly high concentration of analyte in sample.

⑧ Reanalysis of sample in duplicate confirmed sample heterogeneity and inconsistency of results.

⑨ Recovery failed acceptance criteria due to sample heterogeneity.

⑩ LOR was raised due to high conductivity of the sample (required dilution).
