MULBERRY — The massive sinkhole that opened up last month at a Mosaic phosphate processing plant near the Hillsborough-Polk county line may be even deeper than previously thought.
The sinkhole — initially reported as being 300 feet deep — may extend much farther down into the ground.
“We believe it’s deeper than that,” Mosaic executive David Jellerson told reporters on Tuesday. “So the Floridan aquifer — I don’t have the exact dimensions, but just for an example, our recovery well goes down approximately 750 feet.”
