Cleveland Water customers in some eastside communities may experience discolored water due to higher than normal levels of manganese.
Affected areas include portions of the following communities: Beachwood, Cleveland Heights, Euclid, Gates Mills, Highland Heights, Hunting Valley, Lyndhurst, Mayfield Heights, Mayfield Village, Pepper Pike, Richmond Heights, South Euclid.
There is no boil alert in effect. The water is safe to drink. The water meets all primary drinking water regulations. The discoloration is due to hypoxic Lake Erie water coming into our Nottingham Water Treatment Plant.
Hypoxic water can have elevated levels of manganese, which is a mineral that naturally occurs in rocks, soil, and many types of food. The U.S. EPA has a secondary drinking water standard for manganese which means its presence in water is an aesthetic concern and at levels above 50 parts per billion (ppb) discoloration can occur but it is not considered a health risk.
Elevated manganese levels in surface water sources are temporary in nature. Clear water is now leaving the plant. Crews are flushing hydrants throughout the affected area to remove any remaining discolored water.
If you experience discolored water, remember the water is safe to use; however, you should avoid doing laundry as staining may occur depending on how your laundry detergent reacts with the manganese in the water. Water may also have a slight metallic bitter taste which may increase if the water is used to make coffee.
Customers who experience discolored water are encouraged to call our Water Quality Line at 216-664-2639 or our 24-hour Emergency Line 216-664-3060 to report discolored water. Please provide your name, address, telephone number, and when the discoloration began. We are tracking discolored water complaints to strategically flush hydrants and have shifted much of the system load away from the Nottingham plant.
