Flint Creek Power Plant

Download Data

Flint Creek Power Plant has 31 groundwater monitoring wells, 26 of which have been polluted above federal advisory levels based on samples collected between January 26, 2010 and June 28, 2017. Groundwater at this site contains unsafe levels of selenium, sulfate, manganese, arsenic, radium, lead, molybdenum, antimony, boron, chromium, fluoride and lithium.

Site description

The Flint Creek facility houses a coal ash landfill and two ash ponds, the larger of which is approximately 42.8 acres and has a storage capacity of 484 acre-feet. According to permit files, seepage from the landfill was first documented in 2006. A leachate collection system was installed in 2010, and recent tests show that the leachate is high in selenium, boron and specific conductivity. It is unclear where the leachate is disposed. There is no groundwater monitoring of the ash pond area. According to Arkansas' Well Drilling Commission, 45 private wells are located within a 2-mile radius of the site.

This site is among the U.S. Environmental Protection Agency's list of potential damage cases, indicating that it has potentially polluted groundwater or surface water at levels which threaten human health and the environment.
