September 29, 2014 Monitoring Well Abandonment and <br /> Installation Workplan <br /> 1.5. Proposed Monitoring Well Installation <br /> RWQCB staff requires at least three wells installed outside of the LAA 3 area.This <br /> requirement shall be met using one existing downgradient well,one new downgradient <br /> well,and one new upgradient well relative to LAA 3 as shown in Figure 1.The one existing <br /> well(MBRMW-4) is currently located downgradient to the planned percolation ponds. <br /> Proposed well KMW-8 will also be located downgradient to the planned percolation ponds <br /> and proposed well KMW-9 will be located upgradient to the planned percolation ponds at a <br /> distance to minimize potential influences from water table mounding as a result of <br /> percolation pond operations.The depth to groundwater and water quality data at these <br /> locations combined with continued data collection at KMW-4 and KMW-6 shall provide <br /> information about groundwater mounding and gradients beneath the percolation <br /> ponds and groundwater quality changes that result from percolation pond <br /> operations.11 <br /> Table 3 summarizes current and proposed functions of the wells in the WWTF <br /> monitoring network.Wells that function as compliance wells for LAA 1 and 2 will be <br /> retained so the City has the option of the continuing to use these LA-As for recycled <br /> water disposal in the future. <br /> Table <br /> Current and Proposed Monitoring Well Functions. <br /> Well ID Current Function Proposed Function <br /> KMW-1 LAA 1 compliance Continued monitoring at LAA 1 <br /> KMW-2 LAA 2&3 compliance Continued monitoring at LAA 2&3 <br /> KMW-3 LAA 2 compliance Continued monitoring at LAA 2 <br /> KMW-4 LAA 3 compliance Percolation pond compliance <br /> KMW-6 Background Percolation pond compliance <br /> KMW-7 LAA 2 compliance To be destroyed <br /> KMW-8 To be installed Percolation pond compliance <br /> KMW-9 To be installed Upgradient well <br /> MW-5 Pond A, B,C compliance Pond A, B, C compliance <br /> W-1 Pond A, B,C compliance Pond A, B, C compliance <br /> W-2 Pond A, B,C compliance Pond A, B, C compliance <br /> MBRMW-4 None (WRP-1 well) Percolation pond compliance <br /> Table 4 summarizes construction information for the existing wells and the proposed new <br /> wells that will be used to monitor the planned percolation ponds. <br /> u Ibid.
