26 September 2003 <br /> AGE-NC Project No. 02-0896 <br /> Page 5 of 9 <br /> until delivered to the laboratory for analysis. Chain-of-custody protocols will be used to document <br /> sample custody transfer from the field to the analytical laboratory. A chain-of-custody form will <br /> accompany the samples. <br /> 3.4. MONITORING WELL INSTALLATION, DEVELOPMENT AND SURVEY <br /> The three selected soil borings will be completed as single-level ground water monitoring wells <br /> screened from 65 to 85 feet bsg. Following installation, each well will be developed to maximize <br /> water flow and minimize the amount of fine-grained sediment drawn into the well during pumping <br /> or bailing, and the top of each existing and newly installed well casing(well head)will be surveyed <br /> to determine its elevation relative to mean sea level. Procedures for well installation, development <br /> and survey are presented in Sections 4.2. and 4.3., respectively. <br /> 3.5. GROUND WATER SAMPLING AND ANALYSIS <br /> Following the installation of the new monitoring wells, ground water monitoring and sampling <br /> • activities will be conducted for all the monitoring wells and existing domestic and irrigation wells. <br /> on a quarterly basis until directed to modify or discontinue the monitoring program by the <br /> CVRWQCB. Monitoring activities will include recording depth to ground water measurements and <br /> collection of ground water samples for laboratory analysis by a DHS-certified laboratory for the <br /> analytes noted in Section 3.2.Ground water sample collection protocols are described in Section 4.4. <br /> 3.6. PREPARATION OF REPORT OF FINDINGS <br /> Following each ground water monitoring event, a quarterly report will be prepared presenting the <br /> findings.Each report will include a description of work performed and the results of the groundwater <br /> sampling and analysis. Laboratory reports for ground water analyses, testing methods, laboratory <br /> quality assurance/quality control(QA/QC)reports,and sample chain of custody documentation will <br /> be presented in the quarterly report. Conclusions and recommendations will also be included, if <br /> applicable. The report will be in a format acceptable to the CVRWQCB, and will be reviewed and <br /> signed by a California Registered 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 well installation,well development,sampling are described <br /> • below. <br /> Advanced GeoEnvironmental,Inc. <br />
