The County will propose a <br /> work plan to further investigate the source of this impact. <br /> The elevation of groundwater increased approximately four feet at this well since last quarter. <br /> The source of recharge is not apparent,but may be from winter storm water flow in the nearby <br /> Corral Hollow Creek. <br /> Only five Volatile Organic Compounds (VOCs)were detected in MW-5 again this quarter, <br /> indicating the continuing remediation effect by the LFG collection system. <br /> If you have any questions,please call me at(209)468-3066. <br /> Sincerely, <br /> W.
