Box 2009 <br /> Stockton, California 95201 ENVIRONMENTAL HCAL H <br /> PERMIT/SERVICES <br /> Re: Blockbuster Video/Yellow Submarine Site, 140 West Harding Avenue, <br /> Stockton, California <br /> Dear Mike, <br /> Enclosed please find revised quarterly ground water monitoring reports for the third and <br /> fourth quarters of 1992. The original reports for these periods were dated October 28, <br /> 1992, and February 17, 1992, respectively. <br /> The collar elevations of monitoring wells MW-2 and MW-3 were transposed in Table 1 of <br /> the October 28, 1992 report and this error was carried over to the February 17, 1993, <br /> report. Consequently, the ground water gradient maps for these reports are not valid. <br /> However, it is important to note that the ground water gradient map for the third quarter <br /> of 1992, which was included in the report dated November 24, 1992, and entitled <br /> "Monitoring Well Installation" is correct. <br /> The ground water gradient for the third quarter of 1992 sloped to the southwest. <br /> However, the gradient determined for the last quarter of 1992 had again returned to a <br /> slope to the northeast, which was the pattern for the first quarter of 1992 and the third <br /> quarter of 1991. (Ground water measurements were first taken in September, 1991.) No <br /> measurements were taken in the fourth quarter of 1991 or the second quarter of 1992. <br /> The original ground water monitoring report for the third quarter of 1992 inadvertently <br /> contained the analytical data and chain of custody sheet for the third quarter of 1992. The <br /> revised report includes the correct analytical data and chain of custody. Nevertheless, <br /> water samples from all of the wells still remain "none detected" for all analytes. <br /> I am also enclosing copies of the field notes for the September, 1991, sampling event, as <br /> you requested. If you have any additional questions regarding this project, please do not <br /> hesitate to give me a call.. <br /> Sincerely, <br /> j n, , <br /> Rods R. Grunwald <br /> Registered Geologist <br /> enclosures <br />
