In the report, CRA recommends <br /> sampling MW-1 and MW-10 quarterly to evaluate concentration trends in the wells. The <br /> remainder of the wells will remain on semi-annual sampling. <br /> 1) Due to the sharp rise of MTBE concentrations in MWA and the possible rise in <br /> MW-10, the EHD approves CRA's proposal for quarterly sampling of these two <br /> wells for one year after which time sampling is to revert back to semi-annual basis <br /> unless further quarterly sampling is technically justified. <br /> 2) At this time the EHD considers the plume of dissolved MTBE to be adequately <br /> characterized and in view of the increasing MTBE concentrations in MWA, direct <br /> you to prepare and submit a feasibility study to this office for remediation of <br /> impacted soil and groundwater. The report is due in this office by August 30, 2012. <br /> If you have any questions please contact Lisa Medina at (209) 468-3455 or by email at <br /> Imedina@sjcehd.com. <br /> Sincerely, <br /> V-te-��'eeva4-- <br /> 6isaedina, REH Nuel C.
