Please refer to the <br /> F relevant sections of the attached Soil Suitability Study (SSS) for introductory project details. <br /> To expedite San Joaquin County Environmental Health Department (EHD) review, the <br /> F, formatting of this report has been designed to follow, to the greatest degree possible, the <br /> structure of the EHD's Nitrate Loading Study Requirements Checkh'st, dated July 14, 2003. <br /> F, /Because of concern regarding nitrate leaching into ground water from septic systems, a nitrate <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 /> Fil and simplified method to estimate long-term ground-water nitrate impacts on an area-wide basis. <br /> Hantzsche and Finnemore found that over a long period of time,water quality in the upper <br /> saturated ground-water zone closely approximates the quality of percolating recharge waters. They <br /> believe that their method is a good planning tool and provides useful information to planners and <br /> local officials but with some real limitations.
