_ 19 November 1999 <br /> AGE-NC Project No. 99-0604 <br /> Page 6 of 10 <br /> The well screen section will be installed across the observed water table Ievel with five feet of screen <br /> section extending above and fifteen feet of screen section extending below the water table level. <br /> Based on available information, it is anticipated that the total depth of the monitoring wells will be <br /> approximately 70 feet bsg. Wells will be completed as described in Section 4.3. <br /> Following well installation, the wells will be developed to maximize water flow into the well and <br /> minimize the amount of fine-grained sediment drawn into the well during purging for monitoring <br /> -� events. Field procedures for monitoring well installation and development are presented in Sections <br /> 4.3 and 4.4, respectively. <br /> The elevations of the finished ground water monitoring well-casing tops will be surveyed by a <br /> licenced surveyor. <br /> 3.4.4. 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 laboratory analysis. Ground water samples will be <br /> analyzed for TPH-g, BTEX and fuel oxygenating compounds following the methods presented i;1 <br /> Section 3.3. Additionally, monitoring activities will include recording depth to ground water <br /> measurements. Ground water sample collection procedures are described in Section 4.5. <br /> 3.5. REPORT PREPARATION <br /> Upon completion of field work and receipt of the final laboratory results. 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 working under the supervision of <br /> a California Registered Geologist. Procedures for soil sampling, ground water sampling, equipment <br /> decontamination and sample shipment are as follows. <br /> Advanced GeoEnviron mental,Inc. <br />
