Download Data

Boswell Energy Center has 17 groundwater monitoring wells, 10 of which have been polluted above federal advisory levels based on samples collected between May 24, 2016 and October 25, 2017. Groundwater at this site contains unsafe levels of arsenic, sulfate, boron, lithium, molybdenum and cobalt.

Site description

Minnesota Power’s Boswell Energy Center is located in Itasca County, MN along the banks of the Mississippi River. Plant Boswell began operations in 1958 and operated four, coal-fired units that had a maximum generating capacity of 1,073 MW. Plant Boswell currently operates two coal-fired units that combine for a maximum generation capacity of nearly 1,000 MW. The oldest and smallest of the four coal-fired units has been retired since 2016. Boswell Energy Center operates three CCR rule-regulated surface impoundments onsite: the Bottom Ash Surface Impoundment and Units 3 and 4. An inactive surface impoundment, the Old Bottom Ash Pond, is south of those active surface impoundments. You can find the industry-reported data here. For more information on the Boswell Energy Center, see EIP’s 2019 National Coal Ash Report.
