IMPACT OF NITROGEN LOADING FROM SITE PROJECT The recharging of groundwater is the most likely potential feature that could be impacted by nitrogen loading. However, the potential vertical migration of the wastewater would be lesser with the current septic design. Based on the low volume of wastewater to be generated and the significant to ground water, the potential vertical migration would not likely degrade the local ground water. A total of 3.64 ppm restrooms and 5.59 ppm kitchen or 9.23 ppm of additional nitrogen will be added to the subject site through waste water recharge; following final development of the community church. 10.0. TOTAL NITRATE IMPACT FROM PROPOSED PROJECT Based on the assumptions of the report, proposed NO3_N mass of wastewater and the calculations of the NO3_N loading predicted, the proposed development should not negatively impact NO3_N loading rates within the aquifer. The soil at the site appear to be adequate for nitrate degradation and proper leaching of wastewater. 11.0. MITIGATION METHODS PROPOSED To mitigate any known or potential future impacts to soil and ground water from nitrate from proposed new development and increased septic usage, the following mitigations could be implementated: • Maximize wastewater hold time where practical; • Avoid use of bioattenuation chemicals (bleach etc.); • Properly and regularly maintain property septic systems; If re-location or expansion of leach fields becomes necessary, leach lines should include high organic substrates under and surrounding the lines installed. 12.0. CONCLUSIONS Based on the above referenced Soil Suitability and Nitrate Loading Study, AGE concludes the following: Advanced GeoEnvironmental,Inc.
