Seminole Generating Station has 37 groundwater monitoring wells, 24 of which have been polluted above federal advisory levels based on samples collected between December 17, 2009 and October 25, 2019. Groundwater at this site contains unsafe levels of sulfate, boron, molybdenum, radium and arsenic.

Site description

Seminole Electric Cooperative, Inc.'s Seminole Generating Station is a 1,276-MW coal-fired power plant with two units that began operating in 1984. The plant is located near the St. John's River just outside of Palatka, Florida in Putnam County. Waste from the plant is disposed of in an unlined flue gas desulfurization landfill, two unlined storm water runoff ponds, and three lined process wastewater ponds. In 2004, Seminole Electric Cooperative constructed a groundwater collection system to capture contaminated groundwater from deep and shallow aquifers underlying the landfill.
