Groundwater & Well Water Monitoring Program

Le Sueur County’s drinking water is predominately groundwater dependent.  Additionally, the aquifers present within the county not only supply water to county residents but also to the metro area.  It is recommended to test your drinking water at least once per year in order to monitor potential contaminants that could be a risk to your health.  

To view groundwater data, please visit the MPCA's Groundwater Data Interactive Map webpage.

Anoka Soil and Water Conservation District (SWCD) created a great informational video about Groundwater!  

City of Le Center Municipal Well Sealing Project

Le Sueur County in partnership with the City of Le Center was awarded funds to seal an abandoned municipal well, Old Municipal Well #1.  An unused/abandoned well that is not sealed can pose a health, safety, and environmental risk. 

The well is located within a Well Head Protection Area (WHPA), Drinking Water supply Management Area (DWSMA), Inner Wellhead Management Zone (IWMZ), and within one mile of a public water supply.  Additionally, the geological characteristics within the area it is considered high for geological sensitivity, and moderate to high for water table aquifer vulnerability.  For these reasons, the municipal well has been identified as high risk to groundwater and drinking water supplies as well public health.

The City of Le Center was awarded Source Water Protection Competitive Grants in 2021 to help locate and identify old municipal wells.  This project is building off of existing efforts that the City of Le Center has undertaken for groundwater and drinking water protection.   

The well sealing project is anticipated to be completed by 2023.
