Weldon Spring Raffinate Pits

State: Missouri
Location: Weldon Spring
Time Period: DOE 1955–1966; 1967–2002 (remediation)
Facility Type: Department of Energy

Facility Description: In 1955 the U.S. Department of the Army (Army) transferred 217 acres of what had been the Weldon Springs Ordnance Works to the U.S. Atomic Energy Commission (AEC) to construct a uranium feed materials plant. In addition to the plant, the AEC also constructed four raffinate pits adjacent to the plant between 1958 and 1964. The pits were used as collection points and settling basins for chemical and radioactive waste streams coming from the plant.

After closing the plant (including the associated raffinate pits) in December 1966, the AEC transferred the land back to the Army, but retained ownership and control of the wastes in the raffinate pits. On October 1, 1985, the land was retransferred from the Army back to the DOE, which was given responsibility for remediation of the pits.

Surface decontamination of the pits was completed in October 2002.

Contractors: Mallinckrodt Chemical Company (1957–1966); National Lead of Ohio (1966–1981); Bechtel National, Inc. (1981–1985); M-K Ferguson Company and Jacobs Engineering Group (1986–2002.)
