Please refer to the relevant sections of the attached Soil Suitability Study (SSS) for <br /> introductory project details. <br /> ef To expedite San Joaquin County Environmental Health Department (EHD) review,the <br /> formatting of this report has been designed to follow, to the greatest degree possible, the <br /> � I � P � <br /> structure of the EHD's Nitrate Loading Study Requirements Checkus4 dated July 14,2003. <br /> Because of concern regarding nitrate leaching into ground water from septic systems, a nitrate <br /> i � g g <br /> loading analysis was required by the EHD for the proposed development to measure the potential <br /> concentration of percolating effluent and rain fall over the long term. Where percolating effluent <br /> leaches into the ground,ground water quality may be impacted to some degree should the effluent <br /> reach ground water. <br /> The method utilized for the nitrate loading analysis is based on a simple mass balance formula, <br /> ` discussed in a published article by Hantzsche and Finnemore (1992),which provides a convenient <br /> and simplified method to estimate long-term ground-water nitrate impacts on an area-wide basis. <br /> f Hantzsche and Finnemore found that over a long period of time,water quality in the upper <br /> LODI ■ SACRAMENTO ■ MODESTO <br /> ENVIRONMENTAL DIVISION 902 Industrial Way,Lodi,California 95240 ■209.367.3701 ■ 209.369.4228 ■www.noanderson.com <br /> i <br /> .4 <br /> t. <br />
