Snapshot

Walter Scott Jr. Energy Center has 40 groundwater monitoring wells, 36 of which have been polluted above federal advisory levels based on samples collected between March 01, 2016 and December 13, 2019. Groundwater at this site contains unsafe levels of lithium, arsenic, sulfate, molybdenum, boron, cobalt, fluoride, selenium and lead.

Site description

MidAmerican Energy’s Walter Scott Jr Energy Station is in Bluffs, Iowa on the banks of the Missouri River in Pottawattamie County. Opened in 1954, at its peak this plant could produce a combined 1,779-MW of electricity. In 2015, MidAmerican Energy retired Units 1 and 2 in the wake of a 2013 lawsuit settlement between MidAmerican Energy and the Sierra Club. Closure and post-closure plans have been put in place for Plant Walter Scott Jr’s CCR surface impoundment. Plant Walter Scott Jr’s South Surface Impoundment and Monofill are regulated under the CCR rule.
