Significant nitrate attenuation would be <br /> anticipated over the course of this 50-foot span. <br /> It is our professional opinion that, based on the factors discussed above, septic effluent <br /> from the subject Site is unlikely to raise nitrate levels in the ground-water to above the <br /> MCL. Use of a standard septic system with leach lines and sumps should be permitted. <br /> Sincerely, <br /> Live Oak GeoEnvironmental, Inc. <br /> Abigail Racco, REPA o��c,S10NAL <br /> 4� <br /> ¢�DAVID jWELCH % a DAA NONO.2151 <br /> �3 <br /> CERiIEIEG �' * pIDC+CI <br /> ENGINEERING <br /> 6 GEOLpG157 <br /> David J.
