Tank Farms

Steve Bolt repairs an electrical cord at the "tank farms" on the Hanford Nuclear Reservation near Richland, Wash., on Tuesday, March 23, 2004. Bolt and more than 800 others who work at the tank farms, where about 53 million gallons of radioactive waste is stored in 177 underground tanks, are given the option of wearing respirators depending on the location and nature of their work.
