Box 388 <br /> Stockton, California 95201-0388 a <br /> RE: MONITORING, SAMPLING AND ANALYSIS (3) WELLS <br /> LOCATION: Stan Morri Ford , 104 West Eleventh, Tracy, California: <br /> Mr. Knoll, <br /> Enclosed is the second quarter summary report for the last monitoring event at the site referenced <br /> above. Included in this report is a summary table of the sample analysis for this monitoring event <br /> at each of the three monitoring wells. <br /> According to the gradient map, generated by Geological Technics and by the data provided by <br /> Del-Tech's field monitoring report, the subsurface continues to flow in a northerly direction. The <br /> groundwater elevatin did rise slightly since the last monitoring event. <br /> Based upon the laboratory analysis reported during this event MWA is consistent with the <br /> indication of low levels of 1,1,1, TCE and additionaly a low amount of DCA & DCE was <br /> reported. However, during this sampling event MW-3 also indicated some low levels of TCE. <br /> (See attached summary chart and analytical sheets) <br /> Previous monitoring events over five years ago also indicated similar very low levels. <br /> N <br /> The next monitoring event is scheduled for early July. <br /> i <br /> I will notify you within 48 hours of the next field monitoring event. i; <br /> a <br /> Please call my office if you have any questions. <br /> it <br /> Sincerely, <br /> Donald E.
