Results from the Annual Quarter show no exceedences in any well. An <br /> increasing trend was indicated for Chloride in MW-2.

Although Chloride shows an increasing statistical trend, the <br /> concentration is well within drinking water standards. Tetrachloroethene was detected in MW-2 <br /> this quarter,but the concentration was below the established limit for this constituent. <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 /> iso <br /> MICHAEL KALISH <br /> Associate Engineer <br /> MK:vn <br /> N:\Michael\HL\GWmon\4thOOlet.wpd <br /> Enclosure <br /> c: Robert McClellon,Public Health Services, Environmental Health Division <br /> LA 64201 <br />
