Kennedy/Jenks Consultants <br /> �. 3.2 Proposed Monitoring Well Locations <br /> Four new groundwater monitoring wells are proposed for installation under this Work Plan. <br /> These new monitoring wells, together with the existing monitoring wells, will allow Sutter Home <br /> to characterize existing groundwater conditions and monitor groundwater as the new land <br /> application system is brought into service. The proposed and existing monitoring well locations <br /> are shown on Figure 4. The rationale for each of the proposed monitoring wells is discussed <br /> �. below. <br /> Proposed Monitoring Well Rationale <br /> �. GW-19 Monitor groundwater quality exiting the easternmost of the new <br /> LAAs (north); aid in estimating groundwater gradient.. <br /> GW-20 Monitor groundwater quality exiting the easternmost of the new <br /> LAAs (south) aid in estimating local groundwater gradient. <br /> " GW-21 Monitor groundwater quality exiting the westernmost of the new <br /> LAAs(north) aid in estimating local groundwater gradient. <br /> GW-22 Monitor groundwater quality exiting the westernmost of the new <br /> LAAs (south); aid in estimating local groundwater gradient; <br /> fumish lithologic data from greater depths in comparison to <br /> previous onsite borings. <br /> Proposed monitoring wells GW-19 and GW-20, given their relative proximity to existing onsite <br /> wells, will provide groundwater quality data which will be indicative of influences of land <br /> application of process wastewater, if any, over a short distance. The intent of installing a pair of <br /> monitoring wells in this LAA is to more definitively identify any such impacts. The second pair of <br /> proposed monitoring wells, GW-21 and GW-22, will provide further indication of any LAA water <br /> quality impacts, as over time, any observable effects of LAA operations on groundwater quality <br /> L should be more pronounced, given the slow groundwater velocity. The separation of all four <br /> wells will serve to inform estimation of the local hydraulic gradient and the possible effect of the <br /> nearby slough on groundwater flow direction. <br /> r <br /> The well installation process is described in Section 4. <br /> L <br /> i <br /> bw <br /> L <br /> Monitoring Well Installation Work Plan Page 9 <br /> Sutter Home Winery, Lodi;California <br /> 94s-gwWNa`Nb M865005.13 simerhnnelOBrepaSbr 4mla& w4eAm <br />
