VOCs. Soil samples to be analyzed for TPH-ERO will be collected within pre-cleaned, <br />laboratory provided 4-ounce jars. All soil samples will be labeled,. packed on ice and <br />forwarded to the laboratory under chain-of-custody procedures. <br />Temporary Geoprobe Well Installation for Groundwater Sampling <br />PES proposes to convert each of the four Geoprobe soil borings to temporary wells with <br />insertion of a Geoprobe groundwater sampling device, which allows for the extension of <br />a stainless steel slotted screen for collection of a groundwater sample from the point at <br />which the saturated or water-bearing zone is encountered. For this proposal, PES has <br />assumed that the water-bearing zone will be encountered within 20-feet of land surface. <br />Once installed, each temporary well would be purged until such time as the water <br />discharge becomes relatively free of solids or until at least three gallons of water have <br />been removed. PES proposes that groundwater from each of the temporary wells be <br />analyzed for similar constituents identified for soil samples (VOCs and TPH-ERO). <br />Each groundwater sample will be appropriately labeled, packed on ice, and forwarded to <br />the laboratory (priority overnight delivery) under chain-of-custody procedures. PES will <br />plug the boreholes/wells with bentonite once soil and groundwater sampling activities <br />have been completed. <br />Reporting <br />Upon receipt of the laboratory analyses, data will be reviewed and tabularized. <br />Comparison of the data for each respective chemical constituent will be made to the <br />Risk Integrated System of Closure (RISC) Default Closure Values for Residential and <br />Industrial/Commercial Properties. Upon completion of the initial data review, a "Letter <br />Report" will be prepared which presents the sample collection and analytical <br />methodologies used during the field phase of the assessment. Copies of the sample <br />location maps, tabulated data and comparison to RISC Default Closure Values will also <br />be incorporated. Recommendations for any additional assessment activities will be <br />made for review and comment. <br />SCHEDULE <br />PES proposes to commence site investigation activities within one week of receipt of <br />notification to proceed (depending on weather, utility clearance and Geoprobe <br />availability). Upon mobilization, we anticipate completion of the Geoprobe sampling <br />requiring one day. Laboratory analyses will be completed by Pace Analytical on <br />standard one-week turnaround from receipt by the laboratory. Our initial discussion of <br />results will occur within one day of receipt of laboratory analytical results. Our written <br />"Summary Letter Report" will be submitted within one-week of the initial conference. <br />COST ESTIMATE <br />An ESTIMATED COST for Phase II Environmental Assessment Services with respect to <br />the Baseline Environmental Assessment is presented as follows: <br />Field Engineering Services/Project Management $ 900 <br />Geoprobe Rental (assumes 1-day @ $1,400/day, including mobilization) $1,400 <br />Equipment Rental and Expendable Sampling Supplies $ 200 <br />Laboratory Analysis: <br />4 soil samples for % Moisture @ $10/sample $ 40 <br />4 soil samples for analysis of VOCs @ $85/sample $ 340 <br />4 soil samples for TPH-ERO @ $50/sample $ 200 <br />
