30 November 2018 AdvancedGeo AGE Project No. 07-1537 FnvironmentaI Page 3 of 4 'MI • Total petroleum hydrocarbons quantified as gasoline (TPH-g) by EPA Method 8015M • Benzene, toluene, ethylbenzene and total xylenes (BTEX) by EPA Method 8260B • Fuel oxygenates methyl tertiary butyl ether (MTBE), tertiary butyl alcohol (TBA), di-isopropyl ether (DIPE), tertiary amyl methyl ether (TAME) and ethyl tertiary butyl ether (ETBE) by EPA method 8260B • Fuel additives 1,2-dicholoroethane (1 ,2-DCA) and 1 ,2-dibromoethane (EDB) by EPA method 8260B. 2.3. REPORT PREPARATION Upon completion of field work and receipt of final laboratory analysis, a report will be prepared presenting the findings of the investigation. The report will include a description of the work performed and results of the sampling and analysis. Conclusions and applicable recommendations will be included in the report. The report will be in a format acceptable to the CVRWQCB and will be reviewed and signed by a California Professional Geologist. In addition, quarterly groundwater monitoring reports will be prepared for each of the proposed events. 3.0. FIELD PROCEDURES All field procedures will be overseen by an AGE representative under the supervision of a California Professional Geologist. Procedures for the advancement of the soil borings, groundwater monitoring well installation and equipment decontamination are outlined below. 3.1 . MONITORING WELL INSTALLATION A total of two (2) pilot soil borings will be advanced for installation of the proposed shallow (water table) groundwater monitoring wells. The proposed well locations are illustrated in Figure 3. 3.2. WELL COMPLETION The pilot soil borings will be completed as groundwater monitoring wells utilizing 2-inch diameter, Schedule 40 PVC blank well casing and 0.020-inch slotted well screen installed from 25 feet to 50 feet bsg. A diagram of the proposed monitoring well construction is depicted in Figure 4.
