WASTE DISCHARGE REQUIR9%dNTS ORDER NO. GOLDSTONE LAND COMPANY,LLC AND KURT KAUTZ BEAR CREEK WINERY SAN JOAQUIN COUNTY GROUNDWATER CONDITIONS 28. The winery is served by two deep groundwater production wells. The primary well is 135 feet deep and the backup well is 342 feet deep. The well locations are shown on Attachment B2, which is attached hereto and is made part of this Order by reference. 29. The primary well (shallow) produces water of lower quality than the backup (deep) well. Based on analytical testing performed in April 2001, the water supply is characterized in the RWD as follows: Constituent Unit Primary Well Backun Well pH std. 6.1 6.2 Specific Conductance µmhos/cm 915 576 Total Dissolved Solids mg/L 550 400 Calcium mg/L 82 55 Magnesium mg/L 34 21 Sodium mg/L 42 29 Potassium mg/L 2 2 Total Cations meq/L 8.8 5.8 Bicarbonate mg/L 300 250 Sulfate mg/L 31 23 Chloride mg/L 97 30 Nitrate as Nitrogen mg/L 9.5 5.7 Total Anions meq/L 9.0 5.8 30. The Discharger constructed three groundwater monitoring wells at the facility in May 2001. The well locations are shown on Attachment B 1. 31. Based on monitoring events in June 2001, September 2001, April 2002, and July 2002 (the Discharger failed to perform groundwater monitoring in the Fourth Quarter 2001) the water table exists approximately 80 feet below the ground surface and groundwater flows toward the south with minor variations of the flow direction to the southwest and southeast. Monitoring well MW- 1 is near the eastern boundary of the facility site, cross-gradient of the existing LTU. MW-2 is at the upgradient edge of the LTU, and MW-3 is only slightly down-gradient from the LTU. The data are summarized in the following table.
