encounter,the soil bore was abandoned and the local agencies were notified. A recap of the results of sample analysis for MW#5 and MW#6 are attached. CPT#3 was installed on June 13,2000 in the Caltrans right of way.This CPT i5 Northeast of the site, and the data gathered is attached. All replacement monitoring wells have been sampled quarterly, and a recap of the analysis is attached. INSTALLING MONITORING WELLS PROCEDURE FOR INSTALLING MW#5 AND MW#6 Soil borings MW#5 and MW#6 were drilled with an eight in hollow stem auger with samples retrieved at five foot intervals. Samples were extracted with a two-inch split spoon sampler and hammer blows were recorded. Each sample was classified by the Universal Soil Classification System. Soil sleeves were capped with teflon sheets and plastic caps were secured by duct tape. Samples were transferred under chain of custody to GeoAnalytical Labs for analysis by EPA 8020, 5030, and 8260B (see recap for results). Two inch PVC casings with screens at one hundred feet were installed with a#2x#16 sand filter. The monitoring wells were purged and sampled by Del-Tech Geotechnical Services using standard methods of the industry. FINDINGS Monitoring well MW#5 is located near the northeasterly corner of the property. Soil samples retrieved at a depth of thirty feet to eighty-five feet were analyzed positive with various amounts of BETX. All samples analyzed were found to be non-detect for oxygenates in soil bore MW#5. Samples from fifty-five feet and sixty-five feet were lost from the sampler. MW46 is located in the center of the UST excavation. The soil samples retrieved from a depth of fifteen feet to and including sixty-five feet were found to be high in all BETX compounds. Samples from seventy feet to one hundred feet were found to have low amounts of BETX. All samples from MW#6 were found to be non-detect for oxygenates. CONCLUSIONS The soil samples from MW46, located in the center of the UST excavation, contain concentrations of gasoline at rate of more than fifty times the concentrations in MW#5. This is understandable due to the fact that MW#5 is about ninety feet down gradient from MW#6. The method of migration is water born through the sand strata between a depth of thirty and sixty-five feet below the surface. QUARTERLY REPORT OF MONITORING WELL SAMPLES 5/11/2000 PROCEDURE FOR MONITORING WELL SAMPLING Del Tech Geotechnical Support Services secured water samples from the monitoring wells on the above stated property.The work was supervised by Foothill Engineering.All monitoring wells were in good condition and samples were taken using the standard recommended procedures.All samples were extracted using the tube with check valve pump system. Purge volumes and the physical properties of the ground water are attached in the Del-Tech field log. 2
