Results from the Third Quarter Monitoring Event show all constituents were within <br /> established concentration limits with the following exceptions: <br /> • Dichlorodifluoromethane and Xylenes(total)were detected in MW-2. This well was <br /> resampled on September 12,2001, and the County will forward the results when received. <br /> • Methylene Chloride was detected in -4. This well was not resampled. <br /> • Results from this quarter also show a possible exceedence of Electrical Conductivity in <br /> MW-4. However,this may be found to be a sampling anomaly. <br /> An increasing trend was indicated for Chloride in MW-2. Therefore, an intrawell tolerance limit <br /> was not updated for Chloride in MW-2. Note that, although increasing, the concentration is <br /> well below drinking water standards. <br /> This report was prepared to comply with current Waste Discharge Requirements Order No. 96-139. <br /> If you have any questions,please call me at(209)468-3066. <br /> Sincerely, <br /> W.
