  • Site Description
    Stage of Clean-up: Construction Underway

    Conditions at proposal (June 24, 1988): The Hanford 200-Area is in the middle of the 570-square-mile Hanford Site approximately 20 miles north of the City of Richland, Benton County, Washington. Since 1943, Hanford has been the scene of Federal nuclear activities, primarily production of nuclear materials for national defense. The U.S. Department of Energy (USDOE) uses the 200-Area for nuclear fuel reprocessing, finishing, and waste management. Over 230 waste disposal locations have been identified in the 200-Area. The disposal locations and plumes of contaminated ground water cover approximately 215 square miles. An estimated 1 billion cubic yards of solid and dilute liquid wastes comprised of radioactive, mixed, and hazardous constituents were disposed of in trenches, ditches, and landfills in the 200-Area. USDOE has detected TRITIUM, iodine-129, URANIUM+, CYANIDE, and CARBON TETRACHLORIDE at levels significantly above background in ground water beneath the area. Over 2,500 people obtain drinking water from wells within 3 miles of the 200-Area.  More...
