W.Va. Gov Declares Emergency After Chemical Spill – ABC News

About the Elk river in WV:

“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 earlier Thursday. The amount that spilled wasn’t immediately known, but West Virginia American Water has a treatment plant nearby and it is the company’s customers who are affected.

“The water has been contaminated,” said Tomblin, who didn’t know how long the emergency declaration would last.”
