POLLY LOWRY <br /> ASSOCIATE ENGINEERING GEOLOGIST <br /> 3443 ROUTIER ROAD, SUITE A <br /> SACRAMENTO, CA 95827-3098 <br /> RE: FOURTH QUARTER 1997 GROUNDWATER MONITORING REPORT <br /> TRIPLE E PRODUCE, TRACY, CALIFORNIA <br /> Dear Ms. Lowry: <br /> Enclosed is a copy of the Fourth Quarter 1997 Groundwater Monitoring Report for the Triple E Produce <br /> Facility located in Tracy, California. This report has been prepared in accordance with the Waste <br /> Discharge Requirements issued to Triple E Produce by the Regional Board on May 3, 1996. <br /> As indicated in the enclosed report, there has been a substantial decrease in the chloroform plume <br /> originating beneath the former rinse pond at the Triple E Produce Facility. Also, the results from the <br /> Fourth Quarter groundwater sampling and the verification sampling conducted by Triple E in <br /> October 1997 indicate that the chloroform concentrations exhibited during the Third Quarter 1997 <br /> testing were not indicative of actual chloroform levels in underlying groundwater. The Third Quarter <br /> samplings results were formally qualified and subject to verification sampling due to post-sampling <br /> contamination detected in laboratory blanks and trip blanks. The October verification samples and the <br /> Fourth Quarter 1997 results follow the same trend in chloroform levels noted in samples prior to the <br /> Third Quarter testing. <br /> If you have any questions regarding the enclosed report, please do not hesitate to give me a call. <br /> Respectfully submitted, <br /> TRIPLE E PRODUCE <br /> MR.
