' 25 February 2005 <br /> ' AGE-NC Project No. 98-0500 <br /> Page 4 of 6 <br /> ' • Between 145 and 150 feet bsg to assess hydrologic unit six and <br /> • Between 195 and 200 feet bsg to assess the vertical extent of contaminated groundwater. <br /> Followinginstallation each well will be developed to maximize water flow into the well and <br /> � p <br /> ' minimize the amount of fine-grained sediment drawn into the well during bailing. Procedures for <br /> well installation and development are presented in Sections 3.2. <br /> ' Ground water monitoring and sampling of each newly installed ground water monitoring well will <br /> be conducted on a quarterly basis; ground water samples will be analyzed for: <br /> • Volatile organic compounds (VOCs) including benzene, toluene, ethyl-benzene, xylene <br /> (BTEX) and Fuel oxygenates including MTBE, tertiary-butyl alcohol (TBA), di-isopropyl <br /> ether(DIPE),ethyl tertiary-butyl ether(ETBE)and tertiary-amyl methyl ether(TAME),1,2- <br /> ' Dichloroethane (1,2-DCA), ethylene dibromide (EBD)by EPA Method 8020/8260 and <br /> • Total petroleum hydrocarbons quantified as gasoline (TPH-g) in accordance with EPA <br /> Method 8015 Modified. <br /> Ground water sample collection procedures are described in Section 3.5. <br /> 2.3. REPORT PREPARATION <br /> ' Additional site investigation results, with conclusions and applicable recommendations, will be <br /> included in quarterly ground water monitoring reports. The report will include a description of work <br /> ' performed and the results of the soil/groundwater sampling and analysis; conclusions and <br /> recommendations will also be included.The report will be in a format acceptable to the CVRWQCB, <br /> ' and will be reviewed and signed by a California Professional Geologist. <br /> ' 3.0. PROCEDURES <br /> All field procedures will be overseen by an AGE representative under the supervision of a California <br /> ' Registered Geologist. Procedures for well installation, well monitoring and sampling are outlined <br /> below: <br /> Advanced GeoEnvironmental,Inc. <br />
