Zimmer Power Station has 28 groundwater monitoring wells, 16 of which have been polluted above federal advisory levels based on samples collected between December 29, 2015 and December 07, 2017. Groundwater at this site contains unsafe levels of boron, lithium, sulfate, cobalt, arsenic, radium and lead.

Site description

Dynegy's Zimmer Power Station is a 1,425 MW coal-fired power plant located on the Ohio River near Moscow, in Clermont County, Ohio. Four coal ash disposal areas at the site are regulated by the federal coal ash rule: a lined 4-acre coal pile runoff pond, a lined gypsum storage pond, a landfill, and another 9-acre pond called D Basin. The coal pile runoff pond and D basin are considered significant hazard dams, meaning that failure or mis-operation could result in off-site environmental damage. The coal pile runoff pond was constructed in the 1980s and has a storage capaicity of 17 acre-feet. D basin was constructed after 2002 and has a capacity of 4 acre-feet.
