Third day of tap water drinking ban in US city

Hundreds of thousands of Toledo, Ohio residents were on Monday (Aug 4) unable to drink their tap water for the third day as officials said the water supply was polluted due to an algae bloom.

WASHINGTON: Hundreds of thousands of Toledo, Ohio residents entered a third day Monday (Aug 4) unable to drink their tap water after officials warned that the supply was polluted. In a rare 3 am (0700 GMT) Monday press conference, Mayor Michael Collins said the ban, in place since Saturday, remains in effect, even though tests show the quality of the water is improving.

"It's my decision to keep the status quo in effect for at least the next five or six hours," he told local media. "I'm not going to make a decision to expose the city until I feel that I can put my head on a pillow and be comfortable with my decision.”

The ban affects up to 500,000 residents, local media reported. Residents in the midwestern US city and its suburbs were also warned not to boil the water because that would increase the concentration of the microcystin toxin.

"The toxins are the result of a large bloom of algae in the western side of Lake Erie," where the city gets most of its water, the Ohio Management Agency said in a statement Sunday.

The local Red Cross said that the toxin can cause nausea, diarrhea, vomiting, and affect liver functions but is rarely fatal to humans.

Governor John Kasich issued a state of emergency for three counties Saturday due to the contaminated water, allowing state officials to divert resources to the affected area. National Guard soldiers were mobilised and over the weekend help distribute bottled water and pour water into containers from military tank vehicles.

"We are not going to get off of this until this whole thing gets solved, no matter how long that it takes," Kasich said at a joint press conference on Sunday with Collins.

Algae had likely bloomed in the lake due to phosphorous and nitrogen from farm fertiliser runoff, officials said.
