CHARLESTON, W.Va. (AP) — West Virginia regulators say a company has increased by 25 percent its estimate of a chemical mixture that leaked from a storage tank.
The Department of Environmental Protection says Freedom Industries now says about 10,000 gallons leaked from the Charleston plant, up from an initial estimate of about 7,500 gallons.
The DEP says it's still unknown how much of the chemical mixture spilled into the Elk River and forced 300,000 residents in nine counties to stop using their tap water for up to a week except for flushing toilets.
After the initial leak, Freedom Industries later said a second chemical was mixed with the coal-cleaning agent that spilled on Jan. 9.
On Saturday, Gov. Earl Ray Tomblin ordered the company to remove all 17 of its above-ground storage tanks.
