An official says two state air quality employees have appeared in front of a federal grand jury about the West Virginia chemical spill.
State Department of Environmental Protection spokesman Tom Aluise confirmed Tuesday that they testified several weeks ago in Beckley.
Aluise did not provide further details.
U.S. Attorney Booth Goodwin’s office announced an investigation into the Jan. 9 spill the day after it occurred.
Goodwin says 15 to 20 agents from the FBI and Environmental Protection Agency were at Freedom Industries on Jan. 28. The officials spent the day investigating the inside of the tank that leaked and other components of the Freedom facility.
Several other state and federal agencies are looking into the spill from the company that contaminated 300,000 people’s running water for days.
