TOLEDO, Ohio — City leaders in Toledo say it's costing more to keep drinking water free from toxins in Lake Erie and other contaminants in the water.
And they're warning that could force a water rate increase.
Toledo's public utilities director, Ed Moore, says another $3 million is needed on top of the $6 million already spent on chemicals to treat the water.
It was just over a year ago that toxins in the lake contaminated the water supply for 400,000 people in the Toledo area and southeastern Michigan.
The Blade (http://bit.ly/1OldK1O ) newspapers reports that Moore told Toledo's council members that the city may need to raise water rates.
He says a big problem this year was that large ice flows last spring churned up sediments in the Maumee (MAW'-mee) River.
