Preliminary Site Investigation at63 North Pde, Mt Druitt NSW A. D. Envirotech Australia Pty LtdAlong pit running east-west immediately in front of the switch room under stairs.Building fabric within the structure may potentially contain asbestos or other hazardous materials. PCBsare presumed to exist within the capacitors of the light fittings, while asbestos may also be detected withbituminous mastics.Large trees are scattered along the southern and eastern boundaries, all appearing to be in healthycondition, however they appear to have been slightly fire damaged in the south western corner.A large retaining wall exists along the northern boundary, with a access ramp from the north easterncorner of the site. Some general rubbish was also observed along the northern boundary and on top ofthe ramp.The site is generally flat with a slight slope towards the south. Surface water run-off was pooling withinall excavated test pits on site. The information has been provided to ADE in regards to the test pitsexcavated, all approximately 0.5-1.0 m deep BGS.2.3 Surrounding Land-useNorth: Retailing wall and Centrelink office.East: Mount Street with TAFE NSW premises on the opposite side of the road.West: Mount Druitt Court House.South: North Parade with the Rail Corridor on the opposite side of the road.2.4 Summary of Site DetailsTable 2 below summaries details pertaining to the site.Table 2 Site details and information.Site DetailsSite addressSite owner63 North Pde, Mt Druitt NSWSeranin Pty LtdTitle identification Lot 3 in DP 719982Current zoning 3(a) Business – General Clause 44Current site use Derelict site with large two-storey concrete structureProposed site use Multi-Storey Commuter Car ParkInvestigation area Approximately 3500 m 24224 63 North Pde Mt Druitt PSI.v1 final Page 16
Preliminary Site Investigation at63 North Pde, Mt Druitt NSW A. D. Envirotech Australia Pty Ltd3 PHYSICAL SETTING3.1 Site Topography and HydrologyThe Subject site is located on level ground approximately 63 m elevation above mean sea level. Locallythe slope gently drops away to the south towards the rail corridor (Geocentric Datum of Australia, Landand Property Information).Ropes Creek is located 2010 m west of the site. This appears to flows into the Hawksbury River.3.2 Local Geology and SoilThe site is located on the Blacktown soil landscape (bt) as indicated on the Penrith 1:100000geological map, 9130, prepared by the Soil Conservation Services of NSW.The topsoil (A1 horizon) is described with brownish-black loam to clay loam with moderately pedalsub-angular blocky structure and rough-faced porous ped fabric. The pH ranges from slightly acid (pH5.5) to neutral (pH 7.0).Below topsoil there is a hardsetting brown clay loam to silty clay with apedal massive to weakly pedalstructure and slowly porous earthy fabric. It commonly occurs as an A2 horizon. The pH ranges frommoderately acid (pH 5.0) to slightly acid (pH 6.5). Platy ironstone gravel-sized shale fragments arecommon. Charcoal fragments and roots are rarely present.B horizon is described with brown light to medium clay. The pH ranges from strongly acid (pH 4.5) toslightly acid (pH 6.5).The sediments are underlain by Wianamatta Group – Ashfield Shale consisting of laminite and darkgreysiltstone and Bringelly shale which consists of shale, with occasional calcareous claystone,laminite and coal. This unit is occasionally underlain by claystone and laminite lenses within theHawkesbury Sandstone. The site investigation, generally, confirmed the description of the soil profilefor the majority of the site.Fill materialNo fill materials were observed on site. A large access ramp in the north eastern corner of the site maypotentially contain fill materials.3.3 HydrogeologyIt was out of the Scope of Work to study the groundwater flow direction. However, considering thetopography of the site, the local groundwater flow is likely to have a south south-western directiontowards Ropes Creek. Speculation on regional groundwater flow should consider the generaltopography of the site, which slopes towards Ropes Creek, potentially flowing into the HawksburyRiver.Mobile contaminants at the site would be expected to move down to the groundwater surface andmigrate laterally down-gradient from the source towards the creek. A search for registered groundwaterwells via the NSW Office of Water (NSW Groundwater works, NR Atlas website) within 1 km radiusof the subject site was undertaken by ADE. No boreholes were found (refer to Appendix VI- NSWOffice of Water Search).4224 63 North Pde Mt Druitt PSI.v1 final Page 17
