~ Annual Domestic Wastewater System'groundwater Monitoring Report,May 2008 <br /> Sutter Home Winery,Lodi,California <br /> Page 2 <br /> Groundwater samples were collected by filling laboratory-supplied containers with groundwater directly <br /> from the disposable bailers. The sample containers were Iabeled, placed in a cooler with ice, and <br /> delivered in accordance with chain-of-custody procedures to GeoAnalytical Laboratories, Inc. <br /> (GeoAnalyticaI Laboratories)in Modesto, California,within 24 hours of sample collection. <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 /> 0.0004 feet per foot (ft/ft) was calculated using data from groundwater monitoring wells GW-3, GW-4, <br /> and GW-6. Groundwater monitoring field forms are attached. <br /> Table 1.

Laboratory certificates of analysis and <br /> the chain-of-custody record are attached. Specific constituent laboratory analytical methods, detection <br /> limits, and associated California Department of Health Services (DHS) Maximum Contaminant Levels <br /> (MCLS) are included in Table 2, and laboratory analytical results are summarized in Table 3, both on the <br /> following page. <br /> i <br /> I <br /> ;a CONDOR <br />
