1 <br /> ZI INC <br /> '10 2.0 PURPOSE <br /> ' This workplan for drilling soil as and soil as sampling has been prepared as a <br /> p g g 9 P 9 p P <br /> ' discussion document to obtain concurrence from DTSC staff regarding soil gas collection <br /> and analytical methods to be implemented on the LNC property Following discussions <br /> ' with DTSC staff, the document may be modified prior to initiation of field work <br /> ' The purpose of the soil sampling and soil gas investigation is to 1) identify source areas <br /> for VOC's, 2) determine the areal extent and concentration of VOC's on the LNC property, <br /> ' 3) obtain soil samples to measure the physical soil properties of soil moisture, bulk density, <br /> organic content, and porosity, 4) determine the (Ethology beneath the site, and 5) obtain <br /> ' soil samples for limited soil analyses for VOC's to document areas with soil contamination <br /> ' The information collected during the site characterization will be used 1) to determine soil <br /> gas migration pathways, and 2) to design the Soil Vapor Extraction (SVE) pilot program <br /> 1 <br /> 12270020 025 3 <br />
