The <br /> CUF concurred with the EHD directive to assess groundwater using sparge wells in the source <br /> area where monitoring coverage ceased with declining groundwater levels. <br /> j On 10 March 2011, a groundwater monitoring event that. incorporated the sparge wells was <br /> conducted. Although a report of the event has not been received, the laboratory data in the EDF <br /> II on GeoTracker shows the wells to be non-detect for chemicals of concern. The EHD will be <br /> reviewing the site in detail in the very near future and anticipates initiating the closure process. <br /> If the EHD can be of further service, please address questions or comments to Mike Infurna at <br /> (209) 468-3454 or to Nuel Henderson at (209) 468-3436. <br /> I <br /> Sincer ly, <br /> Michael J.
