(AGE), and has the following comments. <br /> In the Report AGE recommends a change in the groundwater monitoring and sampling <br /> frequency. This site previously had been on a semi-annual schedule of monitoring and <br /> sampling. In March 2008 five additional groundwater monitoring wells were installed and <br /> monitoring and sampling was switched to a quarterly schedule until trends were <br /> established in the new wells. AGE proposes a return to a semi-annual schedule for <br /> impacted wells and an annual schedule for non-impacted wells. <br /> The EHD agrees with a reduction in the sampling frequency and approves annual <br /> sampling of wells MW-1, MW-2, MW-3, MW-4, MW-6, MW-10, MW-11 and MW-12, and <br /> semi-annual sampling of wells MW-5, MW-7, MW-8, MW-9, MW-13, MW-14 and the <br /> domestic well located at 4716 Waterloo Road. This change is effective immediately, with <br /> the next semi-annual event to be conducted in August 2009. There is no change in the <br /> analyses, which is restricted to 1,2-dichloroethane. <br /> If you have any questions please call Lori Duncan at (209) 468-0337. <br /> Sincerely, <br /> loIit_ <br /> Lori Duncan, REHS Nuel C.
