GERAGHTY MILLER, INC. '. 3 j The soil generated during the drilling activities will be stockpiled onsite for proper disposal by Boston Chicken, Inc. Four discrete samples will be collected from the stockpiled soil.and submitted to the laboratory. The four discrete samples will be composited in the laboratory into one sample for analysis. The water used during the drilling activities will be stored onsite in 55-gallon drums pending disposal by Boston Chicken, Inc. TASK 3: GROUNDWATER SAMPLING Each monitor well will be allowed to stabilize for a minimum of 48 hours prior to development and sampling. Water-level measurements will be collected from each new monitor well prior to development. The wells will be developed by purging a minimum of three casing volumes of water prior to sampling. The purged water will be stored in covered 55-gallon drums onsite prior to disposal by Boston Chicken, Inc. All equipment that will enter the well will be washed in a solution of phosphate-free detergent and water, and triple-rinsed in potable water. Following well purging, groundwatelr samples will be collected using a new polyethylene bailer for each well. Groundwater samples for laboratory analysis will be collected in appropriate USEPA-approved containers,1 placed on ice, and transported to a State- certified laboratory, along with appropriate chain-of-custody documentation. TASK 4: LABORATORY ANALYSIS The soil and water samples collected during the field activities will be analyzed for total petroleum hydrocarbons as gasoline (USEPA Methi d 8015, modified) and-volatile organic compounds (USEPA Method 8240). The project budget estimate below assumes that a total of three soil samples(one from each boring and the composite sample of the drill cuttings) and four water samples (one each from the proposed we Is, a trip blank, and one from the water generated during drilling)will be analyzed. TASK 5: REPORT PREPARATION Following completion of field activities and receipt of all laboratory data, Geraghty & Miller will prepare a letter report of the results of the assessment activities. This report will include a description of the soil-sampling activities, a site plan showing the soil-sampling locations, and a summary of the results. The report will be limited to the data collected during the field activities. Project No. RCO291.001
