CHARLESTON - The U.S. Chemical Safety Board said it will investigate a chemical spill in the Elk River that contaminated the public water supply in nine counties.
Board chairman Rafael Moure-Eraso said that the board wanted to find out how a leak of such magnitude happened, and how to prevent similar incidents in the future.
Thursday's spill from a Freedom Industries facility in Charleston is also being investigated by the U.S. Attorney's Office and the U.S. Occupational and Safety Administration.
West Virginia American Water had told 300,000 people in the affected areas to not drink or use their tap water.
