PCS Swift Creek Chemical Complex Sinkhole Quick Links


PCS Swift Creek Chemical Complex Sinkhole Opening

On December 10, 2009 the Florida Department of Environmental Protection (DEP) was notified by PCS Phosphate Company of a sinkhole which was discovered inside its phophogypsum stack system at PCS’ Swift Creek Chemical Complex in Hamilton County. The Swift Creek Chemical Complex is located just east of US 41, approximately 10 miles northwest of White Springs, Florida. The stack system stores process wastewater and gypsum resulting from PCS’ phosphate fertilizer manufacturing operations at this site.

It is estimated that 84 million gallons of process water was released into groundwater through the sinkhole. However, based on site inspections and ongoing collection of monitoring data, it appears that PCS’ production wells are containing the process water on site – thereby not contaminating the aquifer offsite or nearby potable drinking water wells. In an abundance of caution the Department has continued its monitoring of the process wells, local private wells and the waters of the Suwannee River.

Information below is updated on a routine basis. For more information contact DEP at (850) 413-8192. Citizens who may be concerned about their drinking water supply can contact the Hamilton County Health Department at (386) 792-1414.
