The groundwater sample collected from boring BH-C contained 0 57 ethyl <br /> benzene, 3 1 ppb total xylenes and 0 55 ppb MTBE <br /> 10.2 Analytical Results - from the Off-Site CPT Borings <br /> The groundwater samples collected from all off-site CPT borings were <br /> analyzed by Kiff Analytical for TPH-D by modified EPA Method 3550/8015 <br /> and TPH-G, BTEX, fuel oxygenates, lead scavengers, alcohols and 1,2-DCP <br /> by EPA Method 8260 The analytical results are tabulated in Table Three <br /> Copies of the certified analytical report and chain of custody form are <br /> included in Appendix I <br /> The groundwater samples collected from 15-feet bgs in boring CPT-26 <br /> contained 630 ppb TPH-G, 54 ppb benzene, 1,400 ppb MTBE, 9 0 p p b <br /> TAME, and 160 ppb TBA Groundwater samples collected from 41 -feet <br /> bgs in this same boring contained an even higher MTBE concentration of <br /> 2,600 ppb, however, no compounds other than MTBE were detected <br /> Groundwater samples collected from 91-feet bgs and 103-feet bgs in this <br /> boring contained 58 ppb and 3 ppb MTBE, respectively The groundwater <br /> sample collected from 103-feet bgs also contained 1 2 ppb 1,2-DCA <br /> The groundwater samples collected from CPT-18, further downgradient, <br /> contained MTBE concentrations of 92 ppb, 75 ppb, 3 7 ppb and 21 ppb at <br /> depths of 16-feet bgs, 38-feet bgs, 57-feet bgs and 97-feet bgs, <br /> respectively The groundwater samples collected from 38-feet bgs and <br /> 97-feet bgs also contained 059 ppb and 069 ppb 1,2-DCA, respectively <br /> The only compound detected in groundwater samples collected from <br /> boring CPT-17, crossgradient to the southwest from CPT-18, was 1 2 ppb <br /> MTBE 1n the sample collected from a depth of 38-feet bgs No MTBE, or <br /> any other compound, was detected in groundwater samples collected <br /> from 16-feet bgs, 63-feet bgs and 92-feet bgs <br /> No compounds were detected in any of the groundwater samples <br /> collected from boring CPT-21, crossgradlent of boring BH-17 to the <br /> northeast <br /> The only compound detected in groundwater samples collected from <br /> boring CPT-19 was 22 ppb TBA in the sample collected from 15-feet bgs <br /> No compounds were detected in the groundwater samples collected from <br /> 41-feet bgs No deeper zones of high permeability were found in this <br /> boring <br /> Franks One Stop Report - March 2001 <br /> -16- <br />
