Escalon Cellars TL F06601.01 <br /> February 9, 2000 Page 2 <br /> currently set at 120 feet and Twining geologists were unable to sound the depth of the wells below <br /> the pumps. The winery is classified as a non-transient non-community water system and is regulated <br /> by the San Joaquin County Health Department. Currently wells No. 3 and No.4 are being sampled <br /> for volatile halocarbons due to the historical detection of Freon 11 and chlorofrom. A summary of <br /> historical laboratory analytical results for Freon 11 and chloroform are included in Table 1. <br /> TABLE 1 <br /> SUMMARY OF WELL NO. 3 AND NO. 4 FREON 11 and CHLOROFORM <br /> ANALYTICAL DATA <br /> Well No. 3 Well No.4 <br /> Date Freon 11 Chloroform Freon 11 Chloroform <br /> ug/1 ug/1 ug/1 u /1 <br /> 12/3/97 NA NA 2.3 NA <br /> 12/11/97 0.8 4.5 NA 2.1 <br /> 3/3/98 1.0 2.6 1.0 1.0 <br /> 4/29/98 0.7 2.1 2.1 1.1 <br /> 8/31/98 NA 2.7 NA 1.6 <br /> 10/5/98 <0.5 NA 0.7 NA <br /> 12/9/98 <0.5 NA 1.2 NA <br /> 3/15/99 <0.5 NA 0.6 NA <br /> 6/22/99 <0.5 NA 0.6 NA <br /> 9/30/99 <0.5 NA NA NA <br /> 1112/15/99 <0.5 NA <0.5 NA <br /> 2.3 Regional Hydrogeology <br /> Ground water beneath the site generally occurs under unconfined conditions. A Spring 1999 ground- <br /> water elevation map produced by the San Joaquin County Flood Control and Water Conservation <br /> District indicates that ground water beneath the site flows generally to the northwest. Depth-to- <br /> groundwater measurements of one of the Escalon Cellars water supply wells indicates that depth to <br /> water beneath the site was approximately 58 feet below ground surface during January 2000. <br />
