CBS News [feedly] TOLEDO, Ohio - Toxins possibly from algae on Lake Erie fouled the water supply of the state's fourth-largest city Saturday, forcing officials to issue warnings not to drink the water and the governor to declare a state of emergency as worried residents descended on stores, quickly clearing shelves of bottled water.
"It looked like Black Friday," said Aundrea Simmons, who stood in a line of about 50 people at a pharmacy before buying four cases of water. "I have children and elderly parents. They take their medication with water."
The city advised about 400,000 residents in Toledo, most of its suburbs and a few areas in southeastern Michigan not to brush their teeth with or boil the water because that would only increase the toxin's concentration.
Toledo's health department also said healthy adults could safely bathe, wash their hands and shower. But while bathing, children should be supervised by adults to prevent drinking the water accidentally, according to CBS News affiliate WTOL. Also, residents should avoid giving tap water to pets.
Toledo issued the warning just after midnight after tests at one treatment plant showed two sample readings for microsystin above the standard for consumption.
Algae blooms during the summer have become more frequent and troublesome around the western end of Lake Erie, the shallowest of the five Great Lakes.
The algae growth is fed by phosphorous mainly from farm fertilizer runoff and sewage treatment plants, leaving behind toxins that have contributed to oxygen-deprived dead zones where fish can't survive. The toxins can kill animals and sicken humans.
Scientists had predicted a significant bloom of the blue-green algae this year, but they didn't expect it to peak until early September.
