City’s Water Treatment and Distribution Services’ (WTDS) statement on Xcel Energy’s Montic

March 24, 2023

Minneapolis Water Treatment and Distribution Services (WTDS) is aware of the Xcel Energy Monticello Power Plant tritium leak and is partnering with the Minnesota Department of Health (MDH) to assess the situation. 

MDH continues to monitor the situation with ongoing testing. At this time, there is no evidence tritium contaminated water has reached the Mississippi River which is the source of Minneapolis drinking water.

As a precautionary measure, WTDS is developing plans to ensure the water we deliver to customers is not impacted in the event contamination does reach the river. Detailed information along with updates associated with the leak can be found on the MDH website at
