Well Sealing

Geologic Cross Section ElysianAn unused and/or abandoned well that is not sealed can pose a health, safety, and environmental risk. This occurs due to your unused well creating a direct pathway for surface runoff, pollutant, and wastes to enter drinking water sources.  This not only affects you, the landowners, but it also affects your community as well.  If your well is no longer being used, it should be sealed as soon as possible.  Your risk of pollutant contaminating your drinking water will be significantly reduced.

Le Sueur County has received grant funds to financially assist landowners sealing their unused/abandoned wells.  To find out more, please click on the links below.

SSTS Low Income Grant

Le Sueur County was awarded funds to help prevent, reduce, and eliminate pollutants in groundwater and surface water from subsurface sewage treatment systems (SSTS). The low-income grant program assists landowners with the financial costs that are required to design, install, repair, and replace a SSTS on residential property that has been deemed an imminent threat to public health or is failing to protect groundwater.  To find out more, please click on the links below.

Groundwater & Well Water Monitoring Program

Le Sueur County's drinking water is predominately groundwater dependent.  Additionally, the aquifers located within the county supply water to not only 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.  Le Sueur County is currently able to test for phosphorus and nitrates.  If you are interested in testing your water for phosphorus or nitrates, please contact the Le Sueur County Enviornmental Services Department at 507-357-8538 or
