Mosaic plant sinkhole dumps 215 million gallons of reprocessed water into Floridan Aquifer

A massive sinkhole that opened underneath a gypsum stack at a Mosaic phosphate fertilizer plant in Mulberry may have dumped at least 215Β million gallons of contaminated water into the Floridan Aquifer over the past three weeks, company officials say.

And it could be months before the hole is plugged, the officials acknowledge.

The 45-foot-wide sinkhole opened at the New Wales plant, where phosphate rock mined elsewhere is converted into fertilizer.

It drained millions of gallons of acidic water laced with sulfate and sodium from a pool atop a 120-foot gypsum stack. An unknown amount of gypsum, a fertilizer byproduct with low levels of radiation, also fell into the sinkhole, which is believed be at least 300 feet deep.
