A possible second breach has been detected at the Florida wastewater reservoir facing imminent collapse, officials said Monday, as efforts to mitigate the damage by draining water ahead of a possible structural failure intensified.

Jake Saur, the public safety director for Manatee County, made the troubling revelation during what’s become a daily press briefing on the impending failure of a reservoir at the abandoned Piney Point phosphate plant outside Tampa.

“At approximately 2 a.m., an infrared drone identified a signature that could indicate a second breach,” said Saur.

However, he and other officials noted that there has been no increase in the rate of leakage from the reservoir, which an army of local, state and federal workers are in the process of draining via pump in an attempt to mitigate damage should the barrier give out.

From a starting capacity of 480 million gallons of water when the first major leak was detected Friday, pumps have now reduced the capacity to about 300 million gallons, officials said at the Monday afternoon briefing.

Workers have been pumping about 35 million gallons per day, but with the arrival of additional equipment, they expect to be able to up that rate to approximately 100 million gallons daily by late Monday, authorities said.

Over 300 area homes have been ordered evacuated by officials, who warned Saturday of an “imminent” collapse.

As of Sunday afternoon, officials warned of the worst-case-scenario potential for a 20-foot “wall of water” to come rushing forth should the reservoir fail.

Also of concern is the quality of the water, which was initially feared to contain traces of radioactivity.

While officials said Sunday that the water itself is not radioactive, the possibility remained that the force of a collapse could topple stocks of radioactive gypsum at the site.
