15 January 1998 <br /> AGE-NC Project No 96-0254 <br /> Page 10 of 16 <br /> Following well installation,the well will be developed in order to maximize water flow into the well <br /> and minimize the amount of fine-grained sediment drawn into the well during pumping and <br /> sampling Procedures for well installation and development are presented in Section 4 2 2 <br /> 3 4 3 Ground Water Sampling Collection and Analysis <br /> I <br /> Following the installation of the additional monitoring wells, ground water monitoring and sampling <br /> activities will be conducted for all the monitoring wells on a quarterly basis for a minimum of one <br /> year (four sampling events) Additionally, monitoring activities will include recording depth to <br /> ground water measurements and collection of ground water samples Ground water sample collection <br /> procedures are described in Section 4 3 Ground water samples will be analyzed by a DHS-certified <br /> laboratory for the analytes noted in section 3 3 <br /> Laboratory reports for ground water analyses, testing methods, laboratory quality assurance/quality <br /> control (QA/QC) reports, and sample chain of custody documentation will be presented in a report <br /> with the findings and recommendations. <br /> 3 5 REPORT PREPARATION <br /> Upon 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 results of the sampling and analysis Conclusions,applicable recommendations, maps <br /> and cross-sections 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 /> 4.0. 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 advancement of probe borings, soil sampling, ground water <br /> sampling, equipment decontamination and sample shipment are outlined below <br /> 41 PROBE BORING ADVANCEMENT <br /> Probe borings will be advanced using a 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 /> hammer to drive soil sampling tools to specified depths <br /> Advanced GeoEnvironmental,Inc. <br />
