90 Percent of Affected Residents Still Can't Drink the Water in Charleston, West Virginia

After a chemical spill

A few thousand more West Virginians learned they could use their tap water Tuesday morning, nearly a week after a chemical leak tainted the supply for them and hundreds of thousands of others.

A "do not use" order was lifted for yet another zone Tuesday -- the Southridge/Southside area near Charleston -- bringing to about 35,000 the number of customers now free to use the water after first flushing their plumbing, the West Virginia American Water Co. said.
