WELL DEVELOPMENT AND SURVEY <br /> Following well installation, each well will be developed to maximize water flow and minimize the <br /> amount of fine-grained sediment drawn into the well during pumping or bailing.After development <br /> the elevation and location of all wells will be surveyed by a professional surveyor. Procedures for <br /> well installation, development and survey are presented in Sections 3.2. and 3.6., respectively. <br /> 2.7. PREPARATION OF REPORT OF FINDINGS <br /> Following soil and ground water sampling; well installation and monitoring of the newly installed <br /> wells a report will be prepared presenting the findings.The report will include a description of work <br /> performed and the results of: 1) soil sampling and ground water analysis collection during well <br /> installations soil borings, 2) monitoring well sampling and 3)the well destruction. The report will <br /> be in accordance with Appendix A to Tri-Regional Recommendations - Reporting, dated 16 April <br /> 2004, prepared by the CVRWQCB for the investigation of UST sites and will be reviewed and <br /> signed by a California Professional Geologist. Conclusions and recommendations will also be <br /> included in the report. <br /> 3.0. FIELD PROCEDURES <br /> All field procedures will be overseen by an AGE representative under the supervision of a California <br /> Professional Geologist. Procedures for soil and water sampling, monitoring well installation, <br /> development, survey, and sampling, plus the destruction of monitoring well MW-5, are outlined <br /> below. <br /> 3.1. PILOT BORINGS AND SOIL SAMPLING <br /> Pilot borings for the wells will be advanced using a CME-75HT drill rig equipped with hollow-stem <br /> augers; the pilot borings for the ground water monitoring wells will be advanced with 8.25-inch <br /> diameter augers. Soil encountered in the pilot borings will be collected at five-foot intervals using <br /> a California modified split-spoon sampler fitted with three 2-inch diameter, 6-inch long brass <br /> sleeves. <br /> Following sample collection,the exposed ends of the leading or other selected sleeve will be labeled <br /> with the boring location,depth,time,date and sampler's initials;the appropriately sealed and labeled <br /> samples will be placed under ice in a chilled container and will be transported under chain-of- <br /> custody to a DHS-certified laboratory for analysis of the chemicals listed in Section 2.4.1.
