The National Priorities List (NPL) listing is for the deep groundwater plume. The deep groundwater plume is at a depth of 324-545 feet. Due to its depth, the deep contamination does not affect individual properties.
The major concern of the deep groundwater plume is its impact to the cities’ municipal wells. To mitigate this impact, both the cities of St. Louis Park and Edina have installed treatment systems to ensure their drinking water meets the requirements of the federal Safe Drinking Water Act and the State’s drinking water guidance values. Once the site is placed on the NPL, the U.S. Environmental Protection Agency (EPA) and the Minnesota Pollution Control Agency will continue working to identify sources of the deep groundwater contamination plume.
If you have additional questions regarding property value, the EPA suggests that concerned property owners consult a professional property appraiser who can give a more accurate response to property value questions and concerns.
