• The US EPA recommended MCL for nitrate in drinking water is 10 mg/L-N. In a worst- <br /> case situation, the maximum buildup of nitrates in the aquifer from the use of septic <br /> systems on the Site is predicted to be 5.09 mg/L-N. The result of the nitrate loading <br /> estimate is below the maximum drinking water standard. <br /> Discussion of Nitrate Loading Results <br /> Total Nitrate Impact <br /> Based on the method and assumptions described, the result of the nitrate loading <br /> estimate indicates that the existing and proposed development on the Site should not <br /> cause a buildup of nitrates in the aquifer above 10 mg/L-N. Because of the satisfactory <br /> result, no mitigation measures are recommended. <br /> It should be noted that, based on the analytical results of the water sample from the <br /> domestic well, it appears that nitrate levels in ground water beneath the Site already <br /> exceed the MCL. <br /> • <br /> • LOGE 1628 Page 12 <br />
