20 December 2000 <br /> AGE-NC Project No. 95-0100 <br /> Page 5 of 8 <br /> 3.2.3. Ground Water Sample Collection and Analysis <br /> Following installation and development of the monitoring wells, ground water monitoring and <br /> sampling events will be conducted at the site. Ground water samples will be collected from the <br /> proposed monitoring wells and submitted for laboratory analysis. Ground water samples will be <br /> analyzed for BTEX, TPH-g, and oxygenating compounds following the protocols presented in <br /> Section 3.2.1. Additionally, monitoring activities will include recording depth to ground water <br /> measurements. Ground water sample collection procedures are described in Section 4.3. <br /> 3.3. 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 and applicable recommendations <br /> will be included in the report. The report will be in a format acceptable to the PHS-EHD and the <br /> CVRWQCB, and will be reviewed and 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 advancement of probe borings, soil sampling, ground water <br /> sampling, equipment decontamination and sample shipment are outlined below. <br /> 4.1. MONITORING WELL INSTALLATION PROCEDURES <br /> Soil borings will be advanced using hollow-stem auger drilling techniques. Soil samples will be <br /> collected from each soil boring at five-foot intervals, starting at 35 feet bsg. Relatively undisturbed <br /> soil samples will be collected in each of the borings using a California modified split-spoon sampler <br /> fitted with 2-inch diameter, 6-inch long brass sleeves. Upon removal from the sampler, the sample <br /> sleeves will be separated with a clean soil knife. The exposed ends of the second sleeve will be <br /> covered with Teflon sheets, capped and sealed with tape. Soils sampled in the borings will be <br /> visually classified by an AGE geologist in accordance with the Unified Soil Classification System <br /> (USCS). Additionally, soil samples will be field screened for the presence of volatile organic <br /> compounds using an organic vapor meter(OVM), equipped with a photo ionization detector (PID). <br /> Soil sample descriptions and OVM readings will be recorded on a log for each boring. <br />
