0 <br /> 1 <br /> ' 3.7 ONGOING MONITORING <br /> In the event that additional monitoring events are requested, the monitoring wells will be <br /> sampled in accordance with the Monitoring and Reporting Program (MRP) from RWQCB, and <br /> previously outlined protocols for groundwater sampling. <br /> ' Field activities and laboratory results will be compiled into a report. The report is usually due to <br /> the RWQCB by the l't day of the second month following the prescribed sampling event interval. <br /> ' Monitoring reports will include the following: <br /> • A description of field activities, observations, and protocols. <br /> • The report will be supported by field logs for each well documenting depth to <br /> groundwater, parameters measured before, during, and after purging, method of <br /> ' purging, calculation of the casing volume, and total volume of water purged. <br /> • Calculation of groundwater elevations, and assessment of the groundwater flow <br /> direction and gradient on the date of the measurement, comparison to previous <br /> flow direction and gradient data, and discussion of seasonal trends, if any. <br /> ' • A scaled map showing relevant structures and features of the facility, the locations <br /> of the monitoring wells, and groundwater contours referenced to mean sea level <br /> ' (msl) datum. <br /> • Results of the sample analysis with copies of certified analytical laboratory results <br /> ' with chain-of-custody documentation; <br /> • Description and documentation of QA/QC procedures employed for field and <br /> laboratory work; and <br /> • An assessment of the results with conclusions and recommendations. <br /> ' • Any annual monitoring data collected in the sampling event. <br /> The subsequent monitoring well sampling events will be conducted in accordance with the <br /> previously outlined tasks. The groundwater samples will be analyzed for the previously listed <br /> analysis, with the exception of the Standard Minerals, which has been identified by RWQCB as <br /> being required for an annual event. <br /> 1 The client will submit the report under a separate cover letter to RWQCB. <br /> 1 <br /> ' 12406/2002R 160 Page 9 of 13 <br /> Copyright 2002,Kleinfelder,Inc.
