i <br /> i <br /> Table 2 <br /> November 1994 Groundwater Elevations <br /> Well # Casing Elevation GW Elevation <br /> MW-4 +5 87 ft -24 29 ft <br /> MW-5 +6 08 ft -25 00 ft <br /> MW-6 +5 87 ft -25 39 ft <br /> Monitoring well MW-4 was purged and sampled with a decontaminated teflon <br /> bailer MW-5 and MW-6 were purged with a submersible pump and samples <br /> were collected with clean disposable bailers Prior to sampling, each monitoring <br /> well was developed by removing a minimum of three well volumes of casing <br /> water Samples were not collected until consecutive conductivity, pH, and <br /> temperature measurements vaned by less than 10% <br /> Site Status <br /> Parevious sampling has shown that benzene and TPH-gasoline are not present <br /> in groundwater on this property Based on the three recent quaterly sampling <br /> events and the historical results from groundwater sampling , once-a-year <br />. sampling for TPH-diesel and measurement of groundwater elevation should be <br /> sufficient to monitor any change in groundwater status Because detections of <br /> diesel fuel have routinely been below 1000 ug/l, Safeway believes that no further <br /> remedial action is warranted at this site If you have any questions regarding this <br /> matter, please do not hesitate to call me <br /> Sincerely, <br /> ERM-WEST, INC <br /> A— ��� <br /> William A pon <br /> Project Manager <br /> WAS/1218 03 <br /> Attachments Noted <br /> cc Mehta Elmore, Safeway <br /> Nhke Frost, Safeway <br /> Elizabeth Thayer, CVRWQCB <br /> f <br />
