MULBERRY – Mosaic Co. officials say they can contain and recapture about 215 million gallons of contaminated water that drained into the Floridan Aquifer last week after a sinkhole opened beneath a gypsum stack at its New Wales fertilizer plant, according to the Ledger.
“I would tell (the public) they can be confident we will not allow any contaminants to migrate off-site,” said David Jellerson, senior director for environmental and phosphate projects, who is supervising the clean up. “I'm quite confident of that.”
Jellerson said the main concern is concentrations of sodium and sulfates in the water, not the acidity. The underground limestone will neutralize the acidity naturally.
A 2-foot drop in the pond on top of the stack was found by a Mosaic technician on Aug. 27, Jellerson said.
Investigators determined a sinkhole had developed underneath the stack, a diagnosis that was confirmed when a 45-foot-wide sinkhole opened up a week later, draining the pond, he said.
