Hydrocarbon odors were noted in all wells except well MW-3. All <br /> water samples and a travel blank, which was made up of deionized water at <br /> ' KA the laboratory, were sent under chain-of-custody to CLAS. <br /> ANALYTIC RESULTS - SOIL <br /> Analytic results for soil samples are presented in Fable 2. Chain- ° f <br /> of-custody forms and laboratory reports are included in Attachment E and <br /> laboratory quality assurance/quality control (QA/QC) reports are included <br /> in Attachment G. <br /> TPPH were not detected in the soil samples collected from borings <br /> B-3 and B-4. TPPH were detected at concentrations ranging from 4 ppm to , <br /> 110 ppm in samples analyzed from boring B-1 collected between 11 ft and <br /> 35 ft. TPPH were detected at 390 ppm for the sample collected at 16 ft ` <br /> in boring 8-5 and at much lower concentrations at 6 ft and 20 ft. TPPH F <br /> were detected at 12 ppm in borings B••5 at 16 ft below grade and at much I <br /> lower concentrations at 20 ft and 31 ft. <br /> Benzene, toluene; total xylenes and ethylbenzene (BTXE) were not. <br /> detected in samples collected from borings 6-3 and B-4. BTXE were <br /> detected in samples collected from borings 6-1, 0-2, and B-5, Benzene ; <br /> ranged from 0.2 ppm to 0.84 ppm in those samples where it was detected. <br /> grease and <br /> Oil were detected at 60 `'� <br /> - g ppm and 150 ppm in the samples 3, <br /> collected at 11 ft and 30.2 ft, respectively, in boring B-3 near the �. <br /> former location' of the waste oil tank. {' <br /> r; <br /> ANALYTIC RESULTS - WATFR- <br /> Analytic results for griundwater samples are presented in Table 1. `f% <br /> Laboratory reports and chain-of-custody forms are included in Attachment # - <br /> - F. Laboratory QA,/QC reports are included in Attachment G. <br /> TPPH, reported as gasoline, were detected in wells MW-1, MW-2 and <br /> am MW-5 at 30,000 ppb, 9,000 ppb and 4,000 ppb, respectively. TPPH were not # ' <br /> detected in the other two wells. [ <br /> 104r1ma9 <br /> .:S xl <br /> { <br /> I usa ' L <br /> t <br /> i. <br />
