The sinkhole at Mulberry, Florida, about 30 miles east of Tampa, damaged the liner system at the base of a stack of hazardous waste, called phosphogypsum, causing a retention pond on top to drain 215 million gallons of contaminated water into the ground.

Phosphogypsum is a radioactive byproduct from the production of phosphate.

"It's an unfortunate incident, but something that is going to be well contained ... in the months ahead," Mosaic Chief Financial Officer Rich Mack said at an investor conference in Toronto.

The company has said it noticed a decline in water levels on Aug. 27, and notified authorities. But it did not otherwise alert residents until posting a notice on its website last Thursday.

BCMI Research analyst Chris Damas said he sold his Mosaic shares after the incident became public.
