Box 40 <br />Excelsior, MN 55331 <br /> <br />RE: Meadow Village, Elk River, MN <br />Well Contamination Issue <br /> <br />Dear Mr. Johnson: <br /> <br />. <br /> <br />North American Wetland Engineering, P.A. (NA WE) received your letter dated <br />September 27, 2000 in regard to the Planning Commission meeting on September 26, <br />2000: In your letter you statep that a neighbor raised the issue of well contamination <br />from groundwater seepage from the proposed community treatment system. <br /> <br />The system that NA WE is proposing uses pre,treatment before disposing the water into <br />the soil. A standard onsite septic system disposes septic tank effluent directly into the <br />ground. Pretreatment in a constructed wetland removes many of the contaminants from <br />the water before discharge to the soil. One of the main purposes of pretreatment is to <br />protect groundwater. <br /> <br />The system will be permitted by the Minnesota Pollution Control Agency (MPCA) and <br />the permit will include groundwater monitoring. At least two downgradient wells will be <br />used to monitor contamination levels. Limits apply to the monitoring wells at ~ the <br />drinking water standards to provide early warning and intervention. Again, the purpose <br />of pretreating the wastewater before subsurface disposal is to protect the groundwater <br />with the added benefit of long. term reliability. <br /> <br />If you have any questions or need additiongl information, please do nol hesitate to contact <br />NA WE at (651) 433~2115, <br /> <br />Sincerely, <br /> <br />North Amcriclln Wetland En2ine~ring, P.A. <br /> <br />. <br /> <br />~~ <br /> <br />Matthew J.
