21 September 1998 <br /> AGE-NC Project No 97-0290 <br /> Page 4 of 8 <br /> Following well Installation, the wells will be developed in order to maximize water flow Into the <br /> well and minimize the amount of fine-grained sediment drawn Into the well during pumping or <br /> balling Procedures for well installation and development are presented in Sections 3 6 and 3 7, <br /> respectively <br /> 2 5 GROUND WATER SAMPLE COLLECTION AND ANALYSIS <br /> Following the Installation of monitoring wells,one ground water monitoring and sampling event will <br /> be conducted at the site Ground water samples will be collected from the each monitoring well and <br /> submitted for laboratory analysis Ground water samples will be analyzed for TPH-g,BTEX and fuel <br /> oxygenates following the protocols presented in Section 2 3 Additionally, monitoring activities will <br /> Include recording depth to ground water measurements and collection of ground water samples <br /> Ground water sample collection procedures are described in Section 3 8 <br /> 26 REPORT PREPARATION <br /> iUpon completion of field work and receipt of final laboratory analysis, a report will be prepared <br /> presenting the findings of the investigation The report will include a description of the work <br /> performed and the results of the sampling and analysis Conclusions and applicable <br /> recommendations will be included in the report The report will be in a format acceptable to the <br /> PHS-EHD and the CVRWQCB, and will be reviewed and signed by a California Registered <br /> Geologist <br /> 3.0. FIELD PROCEDURES <br /> All field procedures will be overseen by an AGE representative under the supervision of a California <br /> Registered Geologist Procedures for the soil sampling, in-situ ground water sampling, monitoring <br /> well Installation,well development,ground water sampling,equipment decontamination and sample <br /> shipment are outlined below <br /> 3 1 PROBE BORING ADVANCEMENT <br /> Probe borings will be advanced using AGE's van-mounted Geoprobe 5400 direct-push probing unit <br /> equipped with 1 25-inch probing rods The Geoprobe advances soil probe borings using a hydraulic <br /> or pneumatic hammer to drive soil and ground water sampling tools to specified depths <br /> Advanced GeoEnviron mental,Inc <br />
