The chemical testing is discussed below. <br />' CHEMICAL TESTING <br /> Waste Oil Tank Excavation <br /> Five discrete samples (WI 4N, W1 4S, W14E, W14W, W1 4C) were collected from the <br /> excavation after removal of disturbed soils and overexcavationlenlargement of the <br /> r excavation. The samples were obtained at the center of the bottom of the excavation <br /> and at the midpoint of each sidewall's intersection with the bottom. The plan <br /> locations of the samples are shown on Plate 3. The samples were analyzed for the <br /> following: <br /> TPH as gasoline by EPA 5030/8015 procedures <br />' O BTEX b EPA 802 analysis <br /> y 0 a alys s <br /> ' Q Total (TTLC) Metals - barium, copper, nickel and vanadium by <br /> the EPA 6010 method <br />' { 0 Soluble (STLC) Metals - barium, copper, nickel and vanadium <br /> by citric acid extraction and EPA 6010 <br /> analysis (Waste Extraction Test <br /> W.E.T. procedure) <br /> 1 r a Soluble (STLC) Metals - barium, copper, nickel and vanadium by <br /> L deionized water extraction and EPA 6010 <br /> analysis <br /> ® pH - sample W 14C only, by the EPA 150. 1 method <br /> 1 Soil Stockpiles <br /> Two discrete samples have been obtained from each approximate 50-cubic-yard <br /> _ volume of stockpiled soil.
