Snapshot

Indian River Power Plant has 27 groundwater monitoring wells, 16 of which have been polluted above federal advisory levels based on samples collected between April 19, 2010 and September 17, 2017. Groundwater at this site contains unsafe levels of manganese, sulfate, arsenic, cobalt, lithium, boron, molybdenum, beryllium, selenium and mercury.

Site description

The Indian River Power Plant is a 784 MW coal-fired plant located near Millsboro, along the Indian River. Upon commissioning, the plant disposed of its coal ash waste on Burton Island, east of the power plant. Berms were built using ash and dredge spoils on Burton Island, resulting in an elevation of the ground surface by about 15 feet, and the conversion of tidal marshes and flats to land made of coal ash contaminated with heavy metals. In 1980, Indian River Power Plant built a landfill on the mainland to dispose of waste, and ceased disposal on Burton Island.

This facility 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.
