The White House has issued a federal disaster declaration in West Virginia, where a chemical spill that may have contaminated tap water has prompted officials to tell at least 100,000 people not to bathe, brush their teeth or wash their clothes.
The chemical, a foaming agent used in the coal preparation process, leaked from a tank at Freedom Industries, overran a containment area and went into the river.
West Virginia American Water expanded its advisory to nine counties last night, up from an original five.
Customers have been told to only use the water for flushing toilets.
There have been no immediate reports of illnesses from the spill.
Schools in at least five of the counties will be closed today.
