The report for this pump test has been supplied as part of a Final Remedial Plan. <br /> Gregg Drilling installed CPT#1 to a depth of 90 feet with soil and groundwater sampling to a depth of <br /> 78 feet on March 3,2003. Three samples of soil and three samples of the groundwater were extracted and <br /> analyzed. All CPT soil and groundwater samples were analyzed as non-detect. <br /> On April 16,2004 pump and treat remediation began with pumping the extraction well,pumping the water <br /> through an activated carbon filter,filling the tank, sample and testing the cleaned water,and trucking the <br /> water to the industrial sewer. Quality control samples were taken and analyzed weekly. <br /> EXISTING W EXTRACTION WELL <br /> kEXTRACTION <br /> DUIT DISCHARGE SAM LLE ppppINT BAKER Al <br /> INT FOR UNTREATED GRr�UNOWATE� <br /> NG 12'X 20'BELOW GROUND CONC.VAULT <br /> 1.25"DISCHARGE LINE TO BAKER TA <br /> C T IST G C ROAD <br /> BAKER TANK 21,000 L <br /> CARBON CANISTER i <br /> SABLE PUMP VOL.=+1-12 GPM MAX <br /> WELL AT-W.T.4g-45' <br /> GENERAL SCHEMATIC SKETCH OF PUMP&TREAT SYSTEM <br /> FDOTHILL ENGINEERING LODI,GA <br /> Over the Memorial Day weekend the pump and treat system was turned off to allow the ground water to <br /> recharge and to recollect any contaminants that might of stuck to the soil particles during draw down. <br /> The pump and treat system resumed on Monday afternoon 5131104. The pump and treat system was <br /> turned off for final closure on June 16, 2004 and final samples of the monitoring wells were taken June <br /> 17, 2004. The well pump and tank and filters were removed on Tuesday, June 22, 2004. <br /> FINDINGS AND RECOMMENDATIONS FOR THIS EVENT <br /> Sampling Procedure <br /> On June 17, 2004, Del-Tech Geotechnical Services, under the supervision of Foothill Engineering <br /> performed a final groundwater monitoring event. Marcel Delacruz of Caltrans was notified of the <br /> monitoring event,as required by Caltrans Permit No.1002-6NV-0218.All monitoring wells were vented <br /> and purged by standard of the industry methods(see Groundwater Field Report by Del-Tech Geotechnical <br /> Services, attached). GMX-1 was purged by dedicated Watera inertia Pump at .5 gpm, MW-2 had very <br /> little water and a sample was collected by hand,MW-3 hand very little water and a sample was collected <br /> by hand,MW-4 had very little water and sample was collected by hand, EW-1 was purged by dedicated <br /> Watera Inertia Pump at .5 gpm. Samples were transported on ice for delivery under chain of custody to <br /> GeoAnalytical Laboratories for analysis. <br /> Sample Analysis <br /> Water samples were analyzed by EPA methods 5030/LUFT for TPHg and 8260B for BTEX and <br /> Oxygenates. Results of all sample analyses are attached in the original laboratory form and also in recap <br /> form (See Water Sample Analysis Recap attached). <br /> Findings From Water Sample Analysis <br /> 2 <br />
