Addendum-Soil Suitability&Nitrate Loading Study Page 4 <br /> Proposed Stama Winery, 17521 Davis Rd,Lodi CA <br /> Project No. 670.16 <br /> November 6,2013 <br /> 8.0 CONCLUSIONS AND RECOMMENDATIONS <br /> I. A percolation test performed by Live Oak Geo Environmental, Inc. at the site of the <br /> new septic system. Based on the percolation test results and the soil profile, we <br /> conclude that the shallow soil percolation characteristics are suitable for a standard <br /> design septic sewage system. <br /> 2. The nitrate loading study indicates the proposed new septic system will add an <br /> additional approximately 112 pounds per year. <br /> 3. The nitrate loading study suggests the uppermost groundwater layer in the vicinity of <br /> the large, future septic system will be receiving a nitrate load approximately 65 percent <br /> of the allowable MCL limit. <br /> 4. The groundwater water well sample contains no detectable DBCP. <br /> 8.2 Recommendations <br /> The results of this investigation suggest that a standard septic design is adequate for the <br /> proposed winery. <br /> 2937 Veneman Ave.,#B240 Geo-Phase Environmental Inc.
