Nitrate loading to groundwater from past and current use of the subject site appears to have <br /> been limited to any loading from septic systems and other typical residential use, such as fertilizes <br /> leaching from nominal landscaping. <br /> Any future nitrate loading to groundwater from proposed facility will be from septic systems, <br /> nominal fertilizer leaching from possible landscape uses, and possibly process water from <br /> proposed facility. Process water and excess irrigation water is planned to be off hauled and <br /> therefore is not to be dispersed to the soil at the site. <br /> 3. Mass balance for Nitrate loading <br /> Calculated nitrate loading to groundwater as a result of conversion of site to employee use only, <br /> and ceasing of dwelling uses, shows in nitrate loading to not exceed any existing nitrate loading. <br /> Conclusion: <br /> Overall with the conversion of the use of the site to simply restrooms and the light uses,in terms <br /> of sewage volumes and nitrate loading to groundwater,will result in less hydraulic loading of a <br /> septic system and less calculated nitrate loading. <br /> Hydraulic loading to the current septic system is quantitatively analyzed to be less than a design <br /> flow from the existing dwelling. <br /> Nitrate loading to groundwater from restroom of the proposed facility is determined to less than <br /> nitrate loading from the currently existing dwellings. <br /> Acorn Onsite, Inc. <br /> Nitrate Loading Study and soil Suitability Report—24707 South Bird Road <br />
