Tank Excavators April 6, 1992 <br /> Project Number 5086-001 Page 2 <br /> representative. Clean brass sleeves were driven into <br /> the removed soil_ The two soil samples, collected from <br /> beneath the tank, were designated BS-1 and BS-2. A third <br /> sample, designated BS-3, was collected from the excavated <br /> soil . See Figure 1 for site map and for soil sample <br /> locations. <br /> SAMPLE DATA <br /> Matrix Sample No. Location Dap_. _!'PH Odor <br /> Soil BS-1 Tank Fill End 11 ' No <br /> Within Tank <br /> Soil BS-2 Suction End 11' No <br /> Beneath Tank <br /> Soil BS-3 Excavated Soil Slight <br /> from Around Tank <br /> SOIL SAMPLE ANALYSIS <br /> Each soil sample was analyzed for Total Petroleum <br /> Hydrocarbons as Diesel with Benzene, Toluene, Ethylbenzene, <br /> Total Xylenes, (TPH-D, BTEX, using EPA Method 5030/8015/ <br /> 8020 ) . <br /> TANK REMOVAL SOIL ANALYTICAL RESULTS <br /> Sample TPH-D B T E X <br /> Number PPM PPb P-Rh 2p1i z)vb <br /> BS-1 ND ND ND ND ND <br /> BS-2 ND ND ND ND ND <br /> BS-3 ND ND 60 25 140 <br /> Note: ppm = parts per million ppb = parts per billion <br /> ND = non detectable <br /> Action: Based on these results, the tank excavation can be <br /> backfilled with clean, imported fill _ The <br /> excavated soil cannot be used for the excavation <br /> backfill . The excavated soil will need to be <br /> aerated on-site or taken to a local landfill for <br /> disposal . <br />
