Hwy 120 <br /> Ripon, CA 95366 <br /> i <br /> As the responsible party, you were notified on April 9, 1991, that <br /> a Work Plan should be submitted to San Joaquin County, Public <br /> Health Services, Environmental Health Division, by May 6, 1991. <br /> This Work Plan has not been received by this office. <br /> Instead, a letter report was submitted by WaterWork on June 18, <br /> 1991. This letter has been reviewed with the following remarks: <br /> 1. San Joaquin County Flood Control maps are not acceptable <br /> for use in determining site specific groundwater <br /> gradients, nor do they take into consideration any site <br /> specific gradient influences (from nearby rivers or <br /> agricultural wells, for example) . The verified <br /> downgradient direction has not yet been determined at <br /> this site. <br /> 2 . Tri-Regional Guidelines does allow for one monitoring <br /> well in the verified downgradient direction within 10 <br /> feet of the former tank excavation area (the source) . <br /> The groundwater gradient is verified by existing <br /> monitoring wells at an adjacent or nearby site. Franzia <br /> Winery does not qualify to use this option because. no <br /> verified groundwater gradient exists in the area. <br /> Additionally, the monitoring well existing at the site is <br /> not in the proposed or expected downgradient direction of <br /> the former tank excavation area. <br /> i <br /> A Division of San Joaquin County Health Care Services �> <br />
