The three pushprobes will aid in determining both the <br /> vertical and lateral extent of any Possible couta,nination associated with the. former UST. Thr <br /> actual sampling locations will be dopcndont on access, surface conditions, and potuaial <br /> interference with subsurface or ovc,head utilities. <br /> Prior to flee advanecnlent oft the pushp:obcs, the first five fcet will be hand-angered to assess <br /> potential underground utilities. PushprobUs will be advanced using a pneumatically driven Steel <br /> probe, Soil samples will be obtainod by insetting a samplo barrel,lined with acetate liners,into <br /> the probe. Tho sample barrel will be lowered to rho desired sampling depth and driven into the <br /> soil. the svttple tubes will be removed and scaled with Teflon film and plastic fitting end caps. <br /> Soil samples will be collected continuously during the advancement of the pushprobcs at depths <br /> ranging from 5-feet to the proposed maximum depth of 15-25 feet bgs.
