(Cincinnati) -- Last week, thousands of gallons of methylcyclohexane methanol leaked into the Elk River, near Charleston, West Virginia. The spill led to a ban on using water from the river, and kept an estimated 300,000 people from having easy access to drinking water.
Now, the bans have been lifted for many in West Virginia, because the chemical has moved downstream, and has reached the Ohio River. In fact, it's expected in the Cincinnati area by Tuesday evening. So, Greater Cincinnati Water Works is closing the intake valves from the Ohio River, where they usually pump about 100 million gallons a day.
The chemical is expected to take about 20 hours to pass through the region. Intake valves will be closed for 48 hours, to be on the safe side.
Cincinnati Mayor John Cranley says they don't anticipate having to call for conservation methods, as there's enough water in reserve and from other sources to supply the customers of GCWW for up to 60 hours.
