The CSB investigation into the chemical storage tank leak that contaminated the drinking water of up to 300,000 residents of nine West Virginia Counties continues. In this video of the tank dismantling activity at Freedom Industries in Charleston, WV, high pressure water tools cut through the metal at various places, and pieces are extracted for analysis. The CSB investigation found that two small holes ranging in size from about 0.4-inch to 0.75-inch in the bottom of the 48,000-gallon tank 396 were caused by corrosion, likely resulting from water leaking through holes in the roof and settling on the tank floor.
