Using EPA Method 8260, analytical results of <br /> ground water samples collected from Monitor Well #1 (MW-1), MW-2, and MW-4 at <br /> the above-referenced site were all non-detect below the detection limits of 5 parts per <br /> billion (ppb) of Methyl tert-butyl Ether (MTBE). The analytical results of the samples <br /> collected on February 5, 1999, were 200, 890, and 300 ppb of MTBE for MWl, 2, and <br /> 4, respectively, using EPA Method 8015/8020. Trace MTBE has been detected using <br /> EPA Method 8260B in the soil samples collected from Boring 2 at depths ranging from <br /> 31 feet below surface grade (bsg) to 86 feet bsg. Although EPA Method 8015/8020 can <br /> be a source of false positive in the quantification of MTBE, PHS/EHD recommends <br /> continued testing for oxygenates using EPA Method 8260. <br /> A "Conclusions/Recommendations" section is included in the Soil fr Groundwater <br /> Investigation Interim Report dated May 18, 1999 prepared by BSK. No summary, <br /> discussions, or recommendations based on the findings were included in the Monitoring <br /> Report Second Quarter 1999. PHS/EHD recommends such a section be included in all <br /> future reports. <br /> There is a conflict between the location of B-1 represented in Figure 2 dated July 1999, <br /> which was included in Monitoring Report Second Quarter 1999 and Soil Fr Groundwater <br /> Investigation Interim Report, and the location of B-1 represented in Figure 3, which was <br /> included in Phase II- Site Assessment Report of Findings dated June 7, 1997 prepared by <br /> WHF, Inc. Figure 3 indicated B-1 to be located between the west end of the former <br /> 550 gallon underground storage tank (UST) and the east side of the former 1,000 gallon <br /> UST. In contrast, Figure 2 indicated B-1 to be located east of the east end of the <br /> former 500 gallon UST and less than 15 feet west of the utility pole. According to field <br /> observation by PHS/EHD staff, Bl is approximately halfway between MW-2 and B-2. <br /> A Division of San Joaquin Countv Health Care Services <br />
