10 October 1999 <br /> AGE-NC Project No. 99-0559 <br /> Page 5 of 8 <br /> The elevations of the finished ground water monitoring well-casing tops will be surveyed by a <br /> licenced surveyor. <br /> 3.4.2. Ground Water Sample Collection and Analysis <br /> Following installation and development of the monitoring wells, one ground water monitoring and <br /> sampling event will be conducted at the site. Ground water samples will be collected from the <br /> proposed monitoring wells and submitted for Iaboratory analysis. Ground water samples will be <br /> analyzed for TPH-g, TPH-d. BTEX and fuel oxygenating compounds following the methods <br /> presented in Section 3.3. Additionally, monitoring activities will include recording depth to ground <br /> water measurements. Ground water sample collection procedures are described in Section 4.6. <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 and applicable recommendations <br /> will be included in the report. The report will be in a format acceptable to the PHS-EHD and <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 soil sampling, ground water sampling, monitoring well <br /> installation and development, equipment decontamination. and sample shipment are outlined below. <br /> 4.1. SOIL SAMPLING PROCEDURES <br /> Soil samples will be collected utilizing a truck mounted hollow-stem auger equipped with a <br /> California split spoon sampler fitted with three six-inch long brass sleeves. Upon removal from the <br /> — sampler, the sample sleeve is separated with a clean soil knife. The exposed ends of the sleeve will <br /> be covered with Teflon sheets, capped and sealed with tape. Soils encountered in the borings will <br /> be 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 /> Thermo Environmental 580A, 10.OeV, calibrated to isobutylenc). <br /> Advnnced GcAnvironmcntal.Inc. <br />
