The results of the stockpile sample laboratory <br /> analyses are shown below in Tables 3 and 4 . <br /> TABLE 3 <br /> Stockpile Sample Analyses <br /> f (Petroleum Hydrocarbons) <br /> analyte/ <br /> lfethod VOC CHC BNA TEPH TEPH TEPH <br /> 8020 8 010 8270 motor oil diesel karosem <br /> 3550 3550 3550 <br /> Detecticm 5.0 5.0 0.05-1.25 50.0 5.0 5.0 <br /> Limit µg/J µ9/kg mg/kg Mg mg/kg Ugft <br /> 145Q-SP-1-4 ND ND 1. 6 di-n-butyl phthalate 1200 ND ND <br /> 0.84 bis (2-ethylhexal) <br /> phthalate <br /> 145Q-SP-5-8 ND ND 1.6 di-n-butyl phthalate 190 ND ND <br /> 0.4 7 bis (2-ethylhexal) <br /> phthalate <br /> Unit Conversions: <br /> µgfkg.parts per billion (ppb) Analyses: <br /> mg/kg:parts per million (ppm) voC - aromatic volatile organics. <br /> CHC - chlorinated hydrocarbons. <br /> BATA - semi volatile compounds. <br /> TEPH - total petroleum hydrocarbons, quantified as motor oil, <br /> diesel and kerosene. <br /> ND - none detected at or above laboratory detection limit. <br /> i CONDOR <br />
