A notice released Tuesday said the water entering the university's water treatment plant was clearer and showed lower levels of manganese. It could take several days for the new, clearer water to replace the discolored water already in the system, according to the notice.
Although the discoloration is unsightly, it shouldn't pose a health risk, said Tim Ward, assistant director of water quality for the Oklahoma Department of Environmental Quality. Manganese can affect the color and taste of water, he said, but it doesn't make the water unsafe to drink.
“Normally, it's not something that would cause a health problem,” he said.
