(AGEI) on your behalf. In <br /> the WP, AGEI proposes to conduct a 3- to 5-day dual phase extraction pilot test <br /> utilizing extraction well EW-4 to extract hydrocarbon vapor and groundwater. <br /> During the field test, groundwater, extracted groundwater and extracted vapor <br /> samples will be collected for laboratory analysis to evaluate the technology <br /> effectiveness on your site. The EHD approves the proposed scope of work as <br /> necessary and adequate [H&S 25296.10 (c)(3)], although the EHD is concerned <br /> that much of the screened interval of EW-4 is in coarse-grained soil and may <br /> yield more water than is expected. Initiate the pilot test within sixty days of date <br /> of this letter and submit a report of findings to this office within sixty days of <br /> completion of the field test. <br /> Questions and/or comments may be directed to Nuel Henderson at <br /> (209) 468-3436. <br /> Nuel C.
