Box 190 <br /> Lodi, CA 95241 <br /> PROBLEM ASSESSMENT REPORT DUE DATE EXTENSION, (800 E T�HICHWAY <br /> 12,_LODI <br /> Your site consultant, Mr. Dave Ellis of du Pont, informed me by <br /> phone on 12 January 1988 that all1drilling, except monitor well <br /> 33P, will commence at 800 East Hi4hway 12 by next week. The <br /> additional drilling should take about one week with well <br /> recovery, sampling and laboratory analyses another four weeks. <br /> DuPont intends to run some short term pump and slug tests to <br /> determine the best location for the bioremediation wells, then <br /> the PAR will be completed and submitted. Based on the above time <br /> table, we agree to your request to extend the PAR due date from <br /> 25 January to 14 March: 1988. <br /> Mr. Ellis agreed that, should monitor well 11 continue to show <br /> detectable levels of contamination, an additional well or wells <br /> will be necessary to the north and west of MW 11. Monitor well <br /> 33P, in the vineyard, cannot be drilled until dry weather <br /> returns. We recommend 'that 33P be drilled as soon as possible <br /> and the results be included as an- addendum to the PAR when the <br /> irionitor-wellA-has"been-completed-and-samples have7been analyzed." <br /> If you have any questions, please call me at (916) 361-5731. <br /> i <br /> GARY S.
