Environmental <br /> Mr Harlin Knoll Resources <br /> 22 September 2003 Management <br />' Page 2 <br />' within the range of historical values Ground water concentration trends <br /> within MW-1 and MW4 are shown in Figures 3 and 4 <br /> 1 Former Tank 2 Location <br /> As shown on Figure 2, no detectable concentrations of hydrocarbons were <br /> observed within monitoring wells MW-2, MW-5, and MW-8 MW-2 <br /> formerly contained elevated TPH detections, which have been reduced to <br /> nondetectable levels Monitoring well MW-6, located adjacent to the former <br /> fuel tank pit, contained hydrocarbon concentrations that are an order of <br />' magnitude lower than previous data Ground water concentration trends <br /> within MW-2 and MW-6 are shown in Figures 5 and 6, respectively <br /> CONCLUSIONS <br /> The results of the most recent ground water sampling event indicate that <br /> the sampled parameters in all wells have shown progressive decreases or <br /> stabilization Five of the eight wells continue to record non-detect results <br /> over the last several sampling events Based upon the data collected, <br /> Heinz is requesting that the following monitoring be removed from the <br />' annual sampling event MW-2, MW-3, MW-5, MW-7 and MW-8 We <br /> would continue to sample MW-1, MW-4 and MW-6 for BTEX and TPH-G <br /> We would also like to discuss the criteria which we need to obtain in order <br />' to receive "No Further Action" of the site <br />' If you have any questions, please call me at (925) 946-0455 <br /> Sincerely, <br /> 444� <br /> Brian S Bjorklund, R G <br />' Pro]ect Manager <br /> cc Mr Scott M Krall, Heinz -Pittsburgh, PA <br />' Mr Marty Hartzel, CVRWCB <br /> Ms Margaret Lagorio, SJCEHD <br />' Mr James F Davenport, The Cranbrook Group <br />
