The system was operating normally <br /> and no repairs were required. The meter reading for the effluent discharge was 1249640. <br /> Attached are the results of the laboratory analyses for nitrate. Based on this reading the <br /> calculation of the nitrogen in the effluent is as follows: 14162 x 41 mg/L equals 9.26 <br /> mg/L nitrogen as nitrate. Since this meets the design criteria of the system no fi nher <br /> analysis or investigation was conducted. <br /> If you have any questions please contact me at the number listed below. <br /> Sincerely, <br /> /,/,x' <br /> H.
