Snapshot

George Neal North Generating Station has 28 groundwater monitoring wells, 28 of which have been polluted above federal advisory levels based on samples collected between February 26, 2010 and December 09, 2017. Groundwater at this site contains unsafe levels of lithium, arsenic, manganese, sulfate, selenium, molybdenum, fluoride and cobalt.

Site description

MidAmerican Energy, a subsidiary of Berkshire Hathaway, owns and operates Neal North Generating Station near Sioux City, Iowa along the Missouri River. The 1,046 MW power station began operating in the 1960s. The station has three surface impoundments that contain coal ash and a coal ash landfill. As of 2011, coal ash disposal occurred in a lined portion of the landfill that was constructed in 2009, and additional disposal areas within the landfill were approved for construction or expansion. Between 2008 and 2010, MidAmerican capped and closed two original disposal areas within the landfill that had received waste since 1978. As a result of a settlement with environmental groups, MidAmerican plans to stop burning coal in two of the Station's three boilers by spring 2016.

George Neal North is listed among the U.S. Environmental Protection Agency's potential damage cases, indicating that it has potentially polluted groundwater or surface water at levels which threaten human health and the environment. Plant George Neal North’s Surface Impoundment 3B and Monofill are regulated under the CCR rule. You can find the industry-reported data here.
