From the mid-1940s to the mid-1980s, the U.S. government constructed and operated facilities at the Hanford Site in southeastern Washington to produce nuclear material for defense purposes. During that 40-year period, large quantities of radioactive and chemical wastes were produced. Some waste entered and contaminated the environment; the remainder is stored in various containers across the Hanford Site. The U.S. Department of Energy (DOE) Order 5820.2A (DOE 1988) mandated that site-specific radiological performance assessments be conducted before placing waste in disposal facilities. These performance assessments must provide a reasonable assurance that the disposal activities will protect long-term human health and safety before DOE approves the facilities. This case study describes a 1980 vadose zone injection experiment and subsequent modeling study intended to demonstrate that model results can provide a reasonable assurance of protection.
