CLEARWATER <br /> G R 0 U P <br /> • ErtvisvrtmertlaP Services <br /> Groundwater Monitoring Schedule <br /> In order to gather important hydrogeologic and water quality data, Clearwater recommends the <br /> continuation of quarterly groundwater monitoring to run through the 2nd quarter of 2002 The need for <br /> continued adherence to the schedule will be re-evaluated after the 2nd quarter of 2002 <br /> Wells MWA through MW-8 will be monitored for the remaining quarters of 2001 Field activities will <br /> be performed in accordance with the Clearwater Field Protocols During each event, all wells will be <br /> sampled for concentrations of TPHg, BTEX, and MTBE by EPA Methods 8015M/8020/8260B and <br /> groundwater levels measured <br /> The results of morutonng efforts will be presented in brief reports which describe field and analytical <br /> methods, results, and project status The reports will be reviewed and signed by a California Registered <br /> Geologist at Clearwater In order to achieve some economy in labor, results of quarterly groundwater <br /> monitoring will be incorporated into larger reports as warranted <br /> Preparation of Feasibility Test Results Report <br /> Once the feasibility testing is complete and the resulting data is evaluated, Clearwater will prepare a <br /> report which will present the test results (i a flowrates, radius of influence, recovery rates) and <br /> provide a general efficiency evaluation of the technologies tested It is anticipated that these test <br /> results will be valuable in future preparation of a Corrective Action flan <br /> ZB178C Workplan for remedial feasibility testing 11 August 2001 <br />
