Huge sinkhole causes water contaminated with radioactive waste to enter Florida drinking water source

At least 980 million litres of contaminated water including radioactive substances has been leaked into one of Florida’s largest sources of drinking water.

Officials said a huge sinkhole opened up beneath a fertiliser plant near Tampa, causing waste water to pass into an aquifer that supplies much of the state.

It contained phosphogypsum, a by-product from the production of fertiliser that contains naturally occurring uranium and radium.

Mosaic, who operates the plant, said the leak posed no risk to the public and was being recovered with pumps before it could contaminate private supplies.
