Annual Domestic Wastewater System`._ undwater Monitoring Report,May 2007 <br /> Sutter Home Winery,Lodi,California <br /> Page 2 <br /> FJ" <br /> GROUNDWATER ELEVATIONS <br /> As specified in the MRP, groundwater level measurements were collected from all 10 monitoring wells at <br /> the Site. Groundwater elevation data are presented in Table 1, below. A westerly groundwater gradient of <br /> 0.0005 feet per foot (ft/ft) was calculated using data from groundwater monitoring wells GW-3, GW-4, <br /> j and GW-6. Groundwater Monitoring Field Forms are attached. <br /> 1 <br /> Table 1 --Groundwater Elevation Data(May 7,2007) <br /> MonitoringGround Depth to Depth to Groundwater <br /> Well Collar Surface Water Below Water Below Elevation <br /> Well .
