' 4.0 GROUNDWATER ANALYTICAL RESULTS <br /> Groundwater laboratory analytical results are summarized in Table i <br /> 1 <br /> TPHg was detected in five wells (MW-1, MW-3, MW-5, MW-7 and MW-9) with the highest <br /> t concentration (16 mg/1) detected in MW-3 Benzene was detected in MW-3 and MW-7 at a <br /> concentration of 200 ug/l and 80 ug/l, respectively MTBE was detected in five wells (MW-1, MW-2, <br /> MW-3, MW-4 and MW-5) at concentrations ranging from 2 0 ug/1 to 33 ug/l Other FOCs were not <br />' detected above the laboratory reporting limits in samples collected from the groundwater monitoring <br /> wells <br /> Well ASI is located within the source area and is screened from 40 to 45 feet below ground surface <br /> (bgs) (deeper than the monitoring wells) The groundwater sample collected from ASI did not contain <br />' concentrations of TPHg, BTEX, or FOCs above the laboratory reporting limits Copies of the <br /> laboratory analytical reports and chain-of-custody documents for the groundwater samples are included <br />' in Appendix C <br />' The water samples collected from domestic wells DW-2R and DW-3 did not contain detectable <br /> concentrations of TPHg, BTEX or FOCs Copies of the laboratory analytical reports and chain-of- <br /> custody documents for the water samples collected from the domestic wells are also included in <br /> lieAppendix C <br /> I <br /> r <br /> i <br /> i <br /> i <br /> i <br /> • <br /> Project No 58643-06-01 -10- September 28 2005 <br />
