y Soil Suitability&Nitrate Loading Study Page 13 <br /> St. Patrick's Church, Escalon, CA <br /> Project No. 607.1 <br /> August 31, 2009 <br /> - 8.0 CONCLUSIONS AND RECOMMENDATIONS <br /> �i 8.1 Conclusions <br />!` <br /> I. A percolation test was performed by NATS at the site of the proposed new <br /> septic system. Based on the percolation test results and the soil profile, <br /> we conclude that soil percolation rate may not be adequate for a standard <br /> design septic sewage system. <br /> 2. The nitrate loading study indicates the existing septic system is producing <br /> a total of about20 pbunds of nitrate nitrogen per year, a , the proposed <br /> } <br /> new system will add an. a ditiona approximately 1 pounds per year. <br /> 3. Based on the nitrate loading study, e upperxnust_grn»n __ er is <br /> t currently receiving a nitrate load that <br /> t does not exceed MCLd the <br /> xoposd sys em 'H •t ncrease the_nitrate oa, _ su fcientlto cause the <br /> MCL limit to be exceeded.. . <br /> F, ®�..d . <br /> 8.2 Recommendations <br /> 1.
