Contaminated Subsurface Earthen Material Identification and Dis osal ' <br /> TASK DESCRIPTION QTY. UNIT UNIT PRICE AMOUNT <br /> 1 Excavate/load <br /> 99 yd s <br /> Contaminated <br /> Soil 6 Hour $49.00 $294 <br /> 2 Soil Samples 6 Each $180 $1,080 <br /> 3 On-site <br /> Supervision 6 Hour $55.69 $334 <br /> 4 Haul to Disposal <br /> Site 4.5 Load $600 $2,700 <br /> 5 Disposal Fee 99 Cubic Yard $21 $2,079 <br /> TOTAL $6,487 <br /> ' Subsurface sampling of ground water and earthen materials indicates that there may be a <br /> potential of contamination at or near the water table. It is assumed that the volume of any <br /> such materials will be one and a half times the volume which Harlan identified, due to <br /> subsurface distribution of contaminants. All costs are assumed to be identical to those in <br /> the table "Contaminated Soils Identification and Disposal". It is assumed that excavation <br /> and disposal of potentially contaminated soils will occur during performance of one or <br /> more other Projects. Therefore, no Mobilization/ Demobilization costs are assigned. <br />
