Ms. Gail Wiggett, C.E.G. <br /> November 13, 1995 <br /> Page 2 <br /> To monitor the effectiveness and evaluate the need for replacement of the ORC Socks, SECOR will <br /> collect dissolved oxygen (DO) measurements in all Site prior to installation. SECOR will collect DO <br /> measurements monthly during the fourth quarter of 1995 to monitor the release of oxygen into the <br /> groundwater at these well locations. <br /> SECOR will perform the fourth quarter groundwater monitoring activities at the Site in mid-December <br /> 1995, approximately four weeks after the ORC Filter Socks are installed. Thus, no additional monitoring <br /> for TPH and BTEX is planned other than the regular quarterly monitoring. The Quarterly Groundwater <br /> Monitoring Report for the fourth quarter will summarize the data collected in the past year and make <br /> recommendations for Site activities 1996. <br /> If you have any questions, or require additional information, please do not hesitate to contact us at(415) <br /> 882-1548. <br /> Sincerely, ' <br /> SECOR International Incorporated <br /> Donald W.
