a 0 15 October 2003 AGE-NC Protect No 96-0232 Page 4of5 23 REPORT PREPARATION Upon completion of field work,a report will be prepared presenting the findings of the investigation The report will Include a description of the work performed and results of the sampling and analysis Conclusions and applicable recommendations will be Included in the report The report will be In a format acceptable to the SJCEHD and the RWQCB, and will be reviewed and signed by a California Registered Geologist 3.0. FIELD PROCEDURES All field procedures will be overseen by an AGE representative under the supervision of a Califomia Registered Geologist Procedures for the soil sampling, equipment decontamination and sample shipment are outlined below 3 1 SOIL/GRAB GROUND WATER SAMPLING PROCEDURES Soil borings P-39 through P-43 will be advanced using direct push technology(Geoprobe 5400 soil probing unit) Relatively undisturbed soil samples will be collected at all borings using a Geoprobe soil sampling assembly loaded with pre-cleaned 1 125-inch by 6-mch brass sleeves Upon soil sample retrieval, the sample sleeve will be separated with a clean soil knife The exposed ends of the second sleeve will be covered with Teflon sheets,capped and sealed with tape Soils encountered in the borings will be visually classified by an AGE geologist In accordance with the Unified Soil Classification System(USCS) Additionally, soil samples will be field screened for the presence of volatile organic compounds using an OVM Following sample collection, each preserved soil sample will be labeled with the boring location, depth, time, date and sampler's Initials Appropriately sealed and labeled samples will be placed in a chilled container under ice and transported under chain-of-custody procedure to a DHS-certified laboratory Grab ground water samples will be collected from each of the above soil borings at depths of 20 feet bsg, 30 feet bsg, 40 feet bsg and 50 feet bsg utilizing a Geoprobe water sampling assembly For the sampling assembly, probe rods will be fitted with a retractable ground water screen and advanced to the total depth of each probe boring, the rods will then be pulled upward to allow ground water to flow into the screen. A bailer fitting will then be placed on the end of 3/8-inch diameter polyethylene tubing,Inserted through the rod assembly into the exposed screen,through which water will be manually pumped The water samples will be analyzed by a DHS-certified laboratory for the same constituents as the soil samples listed above Advanced GeoEnvironmental,Inc
