DTSC comments: In the Work Plan, the groundwater sample collected from MW-27 <br /> was proposed to be analyzed for PAHs after being filtered in the laboratory. The DTSC <br /> requested that unfiltered samples be analyzed for PAHs. <br /> PG&E and ENV America response: Filtered and unfiltered groundwater samples <br /> collected from well MW-27 will be analyzed for PAHs. Turbidity measurements will be <br /> recorded for any unfiltered groundwater samples analyzed for PAHs. <br /> 6. DTSC comments: The DTSC recommended that a stinger be used for over drilling the <br /> wells (for decommissioning) to ensure that the drill stem not drift off from the casing. <br /> PG&E and ENV America response: A stinger will be used for well decommissioning. <br /> Please call me at 415-989-9933 or Ms. Betsy Brunswick of PG&E at 415-973-1642 if you <br /> need additional information or have questions. <br /> Sincerely, <br /> ENV America Incorporated <br /> r <br /> Veen Chee Foong, PE <br /> Senior Project Manager <br /> cc: Ms. Betsy Brunswick, PG&E <br /> P.�PG&E\PGE-05-01 Stockton MW26R In estigationlresponse to DTSC on WP 29Ap2005.dm <br />
