City of Mounds View Page 14 Local Surface Water Management Plan 435-08-135 2.12 GROUNDWATER CONTAMINATION Mounds View has soils that are prone to high infiltration rates and aquifers that are considered as having moderate sensitivity; therefore when considering the use of infiltration BMPs the City should evaluate the sites for existing contamination. The contamination of groundwater is very difficult to rectify, often times requires that installation of expensive treatment systems to purify the water for drinking purposes and in extreme cases the contamination of the groundwater could lead to potential health related problems. Mounds View contains two sites (ID #VP20530 and ID #20531) that the MPCA has designated for the Voluntary Investigation and Cleanup (VIC) Program. According to the MPCA, both of these sites were identified in 2005 as part of the former Bridges Golf Course, now Medtronic Mounds View Campus. The Medtronic parcel which contains the two sites in the VIC Program is identified on Figure 2.5. The Minnesota Department of Health maintains a phasing list that determines the order in which water suppliers will be brought into the wellhead protection planning process. Currently the City does not have a Wellhead Protection Plan, but according to the phasing list it is expected that the City begin the development of a wellhead protection plan in late 2009. Mounds View operates five municipal wells within its jurisdictional boundaries. The City will follow the guidance provided in the Minnesota Stormwater Manual and by the Minnesota Department of Health on evaluating stormwater infiltration projects to address groundwater protection concerns.
