CLEAWATER <br /> �-^ G R Q U P, INC. <br /> • Traffic-rated well 'boxes will be mour ted (flush . to grade) over the <br /> monitoring wells, and locking well cap will be placed in the 'top of the <br /> well casings <br /> • The four monitoring wells will.be developed no sooner than 72 hours <br /> after installation has been completed; development will be accomplished <br /> by surging and pumping a minimum of 10 well volumes from each well. <br /> Well installation, soil sampling, well development, and groundwater <br /> sampling will be conducted in accordance with Clearwater Field Procedures <br /> (Appendix A) and the Health and.Safety Plan (Appendix B). <br /> 2.2_ Chemical Analyses-of Sail and Ground ater,S''mples . <br /> Clearwater will analyze four soil sam les'fr m the soil borin drilled near the. <br /> Y P g <br /> former dispenser islands and four samples; rom each -of the monitoring._well <br /> locations (a total of 20 soil samples). In add tion, groundwater samples will be <br /> collected .from PMW-4 through PMW-7 ollowing_ well development. If . <br /> possible; sampling-- of the- new, wells W' 41 be scheduled,,to coincide with <br /> quarterly.groundwater sampling. <br /> Soil and groundwater samples will be submitted to a state-certified laboratory <br /> and analyzed for TPH.as gasoline (EPA Met od 8015 Modified), TPH as diesel <br /> fuel (EPA.Method 8015 Modified), and BTE (EPA Method 8020 Modified). <br /> The following. analytical. detection limits will be. used for the .compounds <br /> listed above: :. <br /> ? J TPH as gasoline: 50 ppb in water and 1 p iit,per million (ppm) in M) soil <br /> BTEX: 0.5 ppb in water and 0.0)5 ppm in soil <br /> TPH as.diesel. 50 ppb in water and 1 ppm in soil , <br /> _ .3.0 PROJECT REPORTS <br /> _ Following the drilling of the soil boring mid monitoring wells, a report 'will <br /> be submitted to present.the results of the analytical data. The report will <br /> contain the information listed below: <br /> D104 WP 9/95 5 <br />
