1214196 Feasibility study and Corrective Action Plan submitted by Flour <br /> Daniel GTI. Quarterly groundwater monitoring well data indicates <br /> all wells ND for Benzene. MW-1 is ND for TPHg as well. MW-3 <br /> shows declining TPHg concentrations. TPHg in MW 2 has <br /> stabilized between 130 and 300 ppb. Report recommends "No <br /> Further Action" based upon Benzene concentrations and other <br /> factors. <br /> 12/16/96 Well survey by PHSIEHD. Domestic wells are present on north side <br /> of site parcel and on adjacent parcel west of MW-1. <br /> 216197 Telephone conversation with PHSIEHD and Flour Daniel agree_ d to <br /> sample closest domestic wells using silica gel cleanup <br /> 4130197 Domestic wells sampled today. PHSIEHD and Flour Daniel agreed <br /> to analyze samples with and without silica gel cleanup for <br /> comparison <br /> 5116197 Results of domestic well samples submitted to PHSIEHD. Lab <br /> narrative regarding silica gel cleanup "the Diesel Range Organic <br /> present in water sample DW-GW, when not processed with Silica <br /> Gel column cleanup, are part of a continuous organic pattern that is <br /> mostly in the Oil range. Organic matter was visibly present in the <br /> sample before extraction." Possible explanation for the unidentified <br /> contaminant.
