IMPACT OF NITROGEN LOADING FROM SITE PROJECT <br /> Based on the low volume of wastewater to be generated and the significant depth to ground water, <br /> C the potential vertical migration would not likely degrade the local ground water. <br /> 10.0. TOTAL NITRATE IMPACT FROM PROPOSED PROJECT <br /> Based on the assumptions of the report,proposed NO3_N mass of wastewater and the calculations <br /> of the NO3_N loading predicted, the proposed development should not negatively impact NO3_N <br /> j loading rates within the aquifer.The soil at the site appear to be adequate for nitrate degradation and <br /> proper leaching of wastewater. <br /> 11.0. MITIGATION METHODS PROPOSED <br /> To mitigate any known or potential future impacts to soil and ground water from nitrate from <br /> proposed new development and increased septic usage,the following mitigation practices could be <br /> implemented: <br /> • Properly and regularly maintain property septic systems; <br /> Avoid use of bio-toxic chemicals (bleach etc.); <br /> Cay) Maximize wastewater hold time where practical; <br /> • If relocation or expansion of leach fields becomes necessary, leach lines should <br /> include high organic substrates under and surrounding the lines installed. <br /> I <br /> 12.0. CONCLUSIONS <br /> Based on the data collected and reviewed in this report, AGE concludes the following: <br /> • All proposed and approved septic system use and construction should follow the SJCEHD <br /> On-Site Waste Disposal Standards. <br /> • Site redevelopment is appropriate with existing and proposed septic systems. <br /> Advanced GeoEnvironmental,Inc. <br />
