The SLDA site, encompassing 44 acres of privately-owned land, is approximately 23 miles east-northeast of Pittsburgh in Armstrong County, Pennsylvania. It is on the right bank of the Kiskiminetas River, a tributary of the Allegheny River, near the communities of Apollo and Vandergrift. Radioactive waste disposal operations were conducted between 1960 and 1970 at the site.

Low-level radioactive materials, used primarily for nuclear-powered submarine and power-plant fuel, were produced under the Atomic Energy Commission contracts, and eventually disposed of at the SLDA site. Disposal operations were conducted by the Nuclear Materials and Equipment Corporation (NUMEC) firm in the early 1960s. The Atlantic Richfield Company (ARCO) purchased stock in NUMEC in 1967 and sold the stock to Babcock & Wilcox (BWX) Technologies in 1971. BWX Technologies is the current owner of the SLDA site.

In 1981, the Environmental Protection Agency amended disposal regulations and a 2002 law directed the site be added to the Formerly Utilized Sites Remedial Action Program (FUSRAP). The program was initiated to identify, investigate, clean up, or control sites throughout the United States contaminated by the Nation’s atomic weapons and energy programs.
