Hwy. 99 Frontage Rd., Lodi, CA <br /> Dear Mr. Atkinson: <br /> As per today's phone conversation I am writing to provide you with a brief workplan for collecting soil <br /> samples from a boring in "Pond 2" at the subject property. <br /> Workplan <br /> In accordance with item No. 2 in your letter dated March 24, 2000, Ground Zero will supervise the <br /> drilling and sampling of one soil boring. The boring will be placed at previous sampling location C4.5 <br /> (see attached map). <br /> Spectrum Exploration (C-57 512268) will advance the boring using hollow stem auger equipment. The <br /> boring will be drilled to first groundwater, estimated to occur at approximately 45 feet below ground <br /> surface (bgs). Upon completion the boring will be backfilled to the surface with neat cement grout. Soil <br /> samples will be collected for lithologic description and laboratory analysis at five foot intervals from 15 <br /> feet bgs to total depth. Samples will be submitted to State-certified A&L Western Labs for analysis of <br /> total dissolved solids, chloride and sodium using a DI WET extraction procedure. Analytical results and <br /> a boring log will be included in a brief report which will be submitted to the RWQCB and San Joaquin <br /> Co. PHS/EHD. - <br /> If you require any additional information please contact me at your convenience. <br /> 6i QED F <br /> Respectfully, G <br /> l,c�'�� OHO <br /> Grou ero Analysis, �� <br /> c' +�/'/ GREGORY P. <br /> Gregory P.
