Work Plan for Groundwater Monitoring Well Installation at the California Army National Guard <br />Stockton Field Maintenance Shop, Stockton, California <br />4.0 REPORTING <br />Results from groundwater monitoring well installation and groundwater monitoring will be <br />documented in reports to be submitted to the CVRWQCB on a quarterly basis. The <br />approximate schedule for submittal of the reports is addressed below, and will be dependent <br />upon when this Work Plan is approved by the CVRWQCB and well installation activities are <br />implemented. <br />4.1 QUARTERLY GROUNDWATER MONITORING REPORTS <br />The proposed reporting program includes the preparation of three quarterly groundwater <br />monitoring reports, with the first to include a description of well installation activities along with <br />groundwater sampling results. The quarterly reports will include a tabulation of groundwater <br />analytical data and site maps depicting the locations of monitoring wells, analytical results for <br />groundwater samples (contoured, as appropriate), and contoured groundwater elevations <br />indicating the direction and magnitude of groundwater flow. Monitoring well purge/sample logs, <br />COC documentation, and groundwater analytical reports will be included as appendices. The <br />reports will be submitted to the CVRWQCB for review along with a cover letter detailing the <br />respective groundwater monitoring events, findings associated with them, and any problems or <br />concerns that arose during sampling activities. <br />As indicated above, and in addition to groundwater monitoring data, the first quarterly <br />groundwater monitoring report will also include documentation regarding monitoring well <br />installation. This documentation will include tabulated soil sample analytical results and • <br />physical findings associated with soil sampling, well construction, and well development. <br />Appendices to this report will also include soil boring logs/well construction diagrams, COC <br />documentation for soil samples, laboratory analytical reports for soil samples and well <br />development logs. <br />4.2 FOURTH QUARTERLY GROUNDWATER MONITORING REPORT <br />Following completion of the fourth quarterly groundwater monitoring event, a report <br />summarizing the four quarterly monitoring events and related findings will be prepared and <br />submitted to the CVRWQCB for review. The report will provide a thorough assessment of data <br />from the four events, including a comparison of quarterly results for both groundwater chemistry <br />and gradient. In addition, the fourth quarterly report will provide recommendations for future <br />actions or closure, as appropriate to site findings and conditions. <br />All reports will be reviewed and stamped by a California -registered Professional Geologist (PG) <br />or Professional Engineer (PE). Additionally, all reports will be uploaded to the Geo Tracker <br />system, as required. <br />OTIE 10 <br />
