Florida declares state of emergency over toxic wastewater leak
More than 300 homes in the Tampa Bay area have been ordered to be evacuated.
A state of emergency has been declared in Florida after a leak from a large pond of toxic wastewater in Tampa Bay.
More than 300 homes in the area have been ordered to be evacuated, and a motorway near the Piney Point reservoir has been closed off.
Residents were sent a text alert telling them to leave home immediately.
Officials said the 77-acre (31-hectare) reservoir holds millions of gallons of water containing phosphorous and nitrogen from an old phosphate plant.
The pond where the leak was found is in a stack of phosphogypsum, a radioactive waste product from the manufacture of fertiliser.
The water contains small amounts of naturally occurring radium and uranium, and the stacks can also release radon gas.
Attempts to repair the leak late on Friday, by plugging the hole with rocks and other materials, were unsuccessful.
Florida Governor Ron DeSantis declared the state of emergency on Saturday.
Manatee County Administrator Scott Hopes told a press conference that there were concerns the water could flood the area, which is mostly agricultural.
