6.B.(2) Proposal for Phase I Environmental Assessment

inch diameter, 0.01-inch (I.D.) slotted PVC screen and riser to ground surface. Once installed, each temporary well would be purged utilizing a peristaltic pump, or other method, until such time as the water discharge becomes relatively free of solids. PES proposes that groundwater from each of the temporary wells be analyzed for similar constituents identified for soil samples (BTEX, MTBE, TPH-GRO/ERO and PAHs). Each groundwater sample will be appropriately labeled, packed on ice, and forwarded to the laboratory (priority overnight delivery) under chain-of-custody procedures. Reporting Upon receipt of the laboratory analyses, data will be reviewed and tabularized. Comparison of the data for each respective chemical constituent will be made to the Risk Integrated System of Closure (RISC) Default Closure Values for Residential and Industrial/Commercial Properties. Upon completion of the initial data review, a "Letter Report" will be prepared which presents the sample collection and analytical methodologies used during the field phase of the assessment. Copies of the sample location maps, tabulated data and comparison to RISC Default Closure Values will also be incorporated. Recommendations for any additional assessment activities will be made for review and comment. SCHEDULE PES proposes to commence site investigation activities within one week of receipt of notification to proceed (depending on weather, utility clearance and Geoprobe availability). Upon mobilization, we anticipate the completion of the Ground Penetrating Radar within one day, with completion of the Geoprobe sampling requiring one additional day. Laboratory analyses will be completed by Pace Analytical on a one-week turnaround from receipt by the laboratory. Our initial discussion of results will occur within one day of receipt of laboratory analytical results. Our written Summary Letter Report" will be submitted within one week of the initial conference.
