Public water officials say samples show a West Virginia chemical spill is no longer detectable in the Ohio River in the Cincinnati area.
The Greater Cincinnati Water Works shut down river intakes late Tuesday night in anticipation of tainted water arriving from the Elk River spill. Monitoring initially showed levels well below would have been considered hazardous. Officials said Thursday the latest tests showed the tainted water had passed through the area. They said intakes would reopen Thursday afternoon.
The Water Works used water from a suburban Fairfield groundwater plant to avoid service disruptions for Cincinnati users.
Some 300,000 people in West Virginia were told not to drink, shower or wash clothes with tap water after the Jan. 9 Elk River spill of a chemical used in coal processing.
