TURNERS FALLS, Mass. (AP) – Based on information from the Turners Falls Fire Department, The Associated Press erroneously reported on May 12 that four workers at a fish farm had been trapped in a tank dense with feces and sand. In fact, the tank contained a filter system of plastic sheets on which bacteria from fish waste grow, and it had been drained. The rescued workers became trapped among the dislodged panels of plastic in the filter system.
