In what state officials are calling the worst environmental disaster of the decade, a tank at the Brenneman Corporation’s shampoo works in Acmetonia exploded and released more than 600,000 gallons of “Unscented” scent into the Allegheny River. Reports of piles of dead fish along the shore have come in from as far downstream as Wheeling, West Virginia, and residents of riverside communities note that, even after rotting for several days, the dead fish still smell like nothing.
