The source said water from the broken pipe flowed under the tank farm, then froze during the recent cold temperatures and expanded, puncturing the tank from below.

He said that even though the tanks were surrounded by a concrete retaining wall, they were sitting on gravel, so the chemical leak seeped through the gravel, into the ground and under the wall.

West Virginia American Water replaced a leaking water line along Barlow Drive on Tuesday and Wednesday, according to a water company spokeswoman. Barlow Drive is where Freedom’s tank farm is located.
