According to the Minnesota Department of Health (MDH) there is no evidence at this time to indicate impacts or risk to private wells in the vicinity of the plant. The plume has not migrated off the site. There are no private wells located in the direction of groundwater flow between the plume and the Mississippi River. MDH does not have plans to test private wells at this time but will continue to monitor water sources and evaluate the situation.
If you would like to test your private well water for tritium
As a private well owner, you are responsible for regularly testing the water you use for cooking and drinking to make sure it is safe. MDH recommends that you test your well water for several contaminants. While MDH has not issued a recommendation for private well owners to test for tritium in response to the recent release at the Monticello plant, we want to make sure well owners have information about the issue and considerations.
