y, T <br /> Mr. Harlin Knoll <br /> October 16, 1997 <br /> Page 2 <br /> The next quarterly groundwater sampling event should take place in-November 1997. In <br /> a recent telephone conversation with you, PHS/EHD requests that all seven of the - <br /> existing wells (i.e., VW-1, V W-2,MW-1, MW-2, MW-3,-MW-4 and MW-5)be sampled <br /> and analyzed for gasoline hydrocarbons and volatile alcohol- and ether-based oxygenate <br /> compounds by EPA Method 8260. 'Please document this-request in writing so ' <br /> reimbursement for from the UST Cleanup this additional sampling can be secured p Fund. <br /> Pairing the next site visit (November.1997),the drummed wastewater generated from <br /> prior purging of MW4 and MW.--5 will be discharged to the land since gasoline" <br /> hydrocarbons have never been detected in these wells. The purge water generated from k <br /> "'`rizese wells"during the November 1997"sarrtpling effort will beretairicd°iwdrurtis until- - - --. -� <br /> analytical results are available. <br /> During"the"next site visit(November 1997),the drummed wastewater generated from <br /> prior purging of MW-1,"MW-2 and MW-3 will be sampled and analyzed for disposition. <br /> One composite wastewater sample"will be collected from the drums for each of the three <br /> wells. The three composite groundwater samples will be analyzed for gasoline <br /> hydrocarbons;BTEX,and MTBE. <br /> Thank you for your-review.of.these recommendations and' overall assistance on the <br /> ""project. Please respond in,writing totthe recommendations so that pre-approval for the <br /> CAP and design can be secured from the state of California UST Cleanup Fund.
