Mr. Jay Utal <br /> Nextbay Properties, LLC - 2 - 30 October 2012 <br /> Grab groundwater samples will be collected from all ten boring locations. Samples will <br /> be analyzed for TPHg, TPHd, TPHmo, TPHd and TPHmo with silica gel filtration <br /> preparation, and VOCs; in addition, five of the groundwater samples will be submitted <br /> for analysis of PCBs. <br /> ENGEO also proposes to perform a visual reconnaissance of the area to identify <br /> potential supply wells. If any wells are discovered, the supply well closest to the AST <br /> area will be sampled (if the well is active or accessible) and analyzed for TPHg, TPHd, <br /> TPHmo, TPHd and TPHmo with silica gel filtration preparation, VOCs and PCBs. <br /> The Work Plan is approved; please submit the report of results, including a site <br /> conceptual model, by 28 December 2012. If you have questions please contact me at <br /> (916) 464-4696, or via email, at pvellinespwaterboards.ca.gov. <br /> Pat Vellines, P.G. <br /> Engineering Geologist <br /> cc: Mr. Harlin Knoll, San Joaquin County Environmental Management Department, <br /> Stockton <br /> Mr. Morgan Johnson, ENGEO, Inc., Rocklin <br />
