This compound was also detected in that retest(results attached). <br /> Although dichlorodifluoromethane was sporadically detected in years past, it has not been <br /> detected at this well since the fourth quarter of 1999. This inconsistency leads the County to <br /> believe that well MW-2 is not impacted. The County will continue to monitor MW-2 in <br /> accordance with our Waste Discharge Requirements. <br /> If you have any questions, please call me at (209)468-3066. <br /> Sincerely, <br /> Z:' a <br /> W.
