This letter addresses the <br /> potential impact to ground water of the septic system for use with 35 employees per day on the 150- <br /> acre Sutter Home Winery parcel. The 35 employees is the projected staffing when the seven year <br /> project is complete. During the next two years, the staffing will be two to five people. For general <br />' information regarding the location,the Sutter Home Winery development,and soil conditions,please <br /> see our Soil Suitability/Nitrate Loading Study report dated May 27, 1999. <br /> While completing our Soil Suitability/Nitrate Loading Study on May 27, 1999, we <br /> understood that an engineered mounded septic design was to be used for the treatment of wastewater. <br /> The mounded type of system is needed due to high ground water conditions and low percolation <br /> rates.` We understood the proposed septic system effluent would percolate a "0" nitrate level to <br /> ground water and a report describing the engineered design was to be provided to you by another <br /> f consultant. At this time, we understand the consultant is unavailable therefore we were requested <br /> to conduct a nitrate loading analysis for the subject septic system. <br /> The purpose of this investigation is to estimate the nitrate impact of the proposed septic <br /> system effluent to ground water. Using the Hantzsche-Finnemore' mass balance equation, <br /> Condor Earth Technologies, Inc., Sutter Home Wine Processing Facility Percolation Test.
