Millions of gallons of contaminated water have flowed into a massive sinkhole in central Florida.

The sinkhole at a fertilizer plant opened last month.

According to the company, the Florida Department of Environmental Protection was notified immediately and has been on site every day since it was discovered on Aug. 27.

The large sinkhole opened beneath a gypsum stack, and the water has flowed into an aquifer.

That water is slightly radioactive and contains phosphoric acid.

The company says it has a large recovery well close by that is pulling contaminated water out of the aquifer and pushing it back into the plant where it will be used to process fertilizer.
