The report for this pump test has been supplied as part of a Final Remedial Plan. . Gregg Drilling installed CPT#1 to a depth of 90 feet with soil and groundwater sampling to a depth of 78 feet on March 3,2003.Three samples of soil and three samples of the groundwater were extracted and analyzed. All CPT soil and groundwater samples were analyzed as non-detect. On April 16,2004 pump and treat remediation began with pumping the extraction well,pumping the water through an activated carbon filter,filling the tank, sample and testing the cleaned water,and trucking the water to the industrial sewer. Quality control samples were taken and analyzed weekly.

The pump and treat system resumed on Monday afternoon 5/31/04. The pump and treat system was turned off for final closure on June 16, 2004 and final samples of the monitoring wells were taken June 17, 2004. The well pump and tank and filters were removed on Tuesday, June 22, 2004. Quarterly monitoring has resumed with the Third Quarter of 2004, September 17, 2004 FINDINGS AND RECOMMENDATIONS FOR THIS EVENT Sampling Procedure On September 17,2004, Del-Tech Geotechnical Services,under the supervision of Foothill Engineering performed the third quarter groundwater monitoring event for 2004. Marcel Delacruz of Caltrans was notified of the monitoring event , as required by Caltrans Permit No.1002-6NV-0218. Only EW-I and GMX-1 had water. Monitoring wells MW-2,3, and 4 were dry. GMX-1 was not purged because there was such little water available. A grab sample with a bailer was taken. EW-1 was purged at 2 gpm by a dedicated Watera Inertia Pump. Samples were transported on ice for delivery under chain of custody to GeoAnalytical Laboratories for analysis. Sample Analysis Water samples were analyzed by EPA methods 5030/LUFT for TPHg and 8260B for BTEX and Oxygenates. Results of all sample analyses are attached in the original laboratory form and also in recap . form (See Water Sample Analysis Recap attached). 2
