Country Club Food & Fuel page 2 1850/1856 Country Club Blvd, Stockton EHD also reviewed the site conceptual model for the UST site adjacent to, and just down-gradient from your site. The increasing levels of MtBE and the presence of TBA in their upgradient wells could be from the contaminant plume at your site migrating on to their site. The site, Sanchez Property, is currently conducting ground water extraction as an interim remedial activity under approval of EHD. The potential of the contamination from your site migrating to their site could result in a commingled plume and overwhelm their remedial efforts. In order to verify if a plume is migrating off of your site, EHD requires you to place a monitoring well close to former boring B-2. This monitoring well should be at least a 4-inch diameter well and should be screened in such a manner as to provide valid first interface ground water samples. The well could also be used for ground water extraction should it be determined that the petroleum contamination at your site has migrated to this location. If elevated.levels of dissolved petroleum are detected in this new monitoring/extraction well, EHD will require interim remedial activity(ground water extraction and treatment)to control the migration of your plume. Please be prepared to meet this requirement in a short period of time once the well is installed and if analytical data indicates a problem exists. A work plan for the monitoring well installation is due at EHD by November 28, 2005. Please direct your submittals to Michael Infurna and you may call him at (209) 468-3454 if you have any questions.
