0 0 <br /> Monitoring Well Installation Work Plan <br /> White Slough Water Pollution Control Facility <br /> • The measurement point on the casing will be clearly and permanently marked for <br /> future water level measurements. <br /> • The location on the pad will also be permanently marked. <br /> 5.0 GROUNDWATER MONITORING AND REPORTING <br /> The City will measure the depth to groundwater in the new monitoring well at least 48 hours <br /> after well development. An initial water quality sample, as well as a concurrent sample from well <br /> WSM-2,will be collected following the depth measurement. The depth measurement and sample <br /> collection will be performed consistent with the monitoring requirements for the existing <br /> monitoring wells as specified in Section VLA.1 of the MRP. This initial water quality sample <br /> from the new well and the concurrent sample from WSM-2 will be analyzed for the parameters <br /> specified in Table E-8 of the MRP. <br /> The Monitoring Well Installation Report will be submitted to the Regional Board to document <br /> the monitoring well logging, construction, and development; the surveyed coordinates; and the <br /> results of the initial sampling event. The Monitoring Well Installation Report will be submitted <br /> with the City's next quarterly groundwater monitoring report following receipt of the analytical <br /> results from the initial monitoring event. The City will also include relevant construction and <br /> water quality information for the new monitoring well in the BPTC Study Report. <br /> 6.0 IMPLEMENTATION SCHEDULE <br /> As mentioned above, the City is in the process of evaluating BPTC efforts at the WPCF, and will <br /> soon be preparing a BPTC Study Report to document the evaluation of BPTC efforts conducted <br /> over the last several years. The City would also like to include an evaluation of water quality <br /> data from the proposed well in the BPTC Study Report, as a preliminary step to potentially <br /> decommissioning WSM-2. If the proposed well can be installed by September of this year, we <br /> anticipate being able to collect at least three monthly samples. The results of this sampling could <br /> be evaluated as part of the BPTC Study Report, which will be submitted to the Regional Board <br /> by February 1,2015. <br /> The City would prefer to implement the Work Plan immediately upon receipt of written approval <br /> from the Regional Board,which we understand may take 30 days or more. However, installation <br /> of the monitoring well in September is necessary to meet the schedule outlined above for the <br /> BPTC Study Report. Therefore, if the City has not heard from the Regional Board by Monday, <br /> September 22, 2014, the City will proceed with implementing the Work Plan prior to receiving <br /> formal approval. In either case, as indicated in Table 4-1, the Regional Board Executive Officer <br /> will be notified at least five working days before commencing site work. <br /> Summarized in Table 6-1 are the anticipated completion dates for the major tasks described in <br /> this Work Plan. <br /> WEST YOST ASSOCIATES 9 City of Lodi <br /> September 2014 Monitoring Well Installation Work Plan <br /> w\c\213\06-14-31\wp\WP\083014_1 RWP <br />
