(AGE), and the groundwater analytical data <br /> submitted to Geotracker for the third quarter of 2008, and has the following comments. <br /> Five additional groundwater monitoring wells were installed downgradient from your site in <br /> March of 2008 to investigate the lateral extent of the 1,2-dichloroethane (1,2-DCA) in the <br /> shallow groundwater. Two of these wells had concentrations of 1,2-DCA above reporting <br /> limits during the third quarter 2008 monitoring and sampling event. <br /> Groundwater monitoring and sampling has been being conducted at your site on a semi- <br /> annual schedule. The EHD directs that quarterly groundwater monitoring and sampling of <br /> all site wells resume until a consistent history is established in the new wells. In addition, <br /> the domestic well located at 4716 Waterloo Road should be added to the sampling <br /> regimen. The change in monitoring and sampling frequency should begin with the fourth <br /> quarter of 2008. <br /> If you have any questions please call Lori Duncan at (209) 468-0337. <br /> Sincerely, <br /> Lori Duncan, REHS Nuel C.
