The U.S. Army Corps of Engineers last week awarded a $95 million contract for environmental remediation in the St. Louis, Mo., area under the Formerly Utilized Sites Remedial Action Program (FUSRAP).
HydroGeoLogic, headquartered in Reston, Va., overcame one other bidder for the cost-plus-fixed fee deal, according to an Aug. 8 procurement notice from the Pentagon. “Work locations and funding will be determined with each order, with an estimated completion date of Feb. 7, 2025,” the notice says.
FUSRAP, created in 1974, identifies, evaluates, and remediates sites that were radioactively contaminated from the 1940s to 1960s by nuclear-weapon and energy operations of the Manhattan Engineer District and Atomic Energy Commission.
HydroGeoLogic is the incumbent contractor for the St. Louis sites, under an award issued in 2016 and worth an estimated $50 million through March 2021.
In the procurement notice issued in April, the Army Corps said the award would involve cleanup at two radioactively contaminated locations: The St. Louis Downtown Site, used by Mallinckrodt Chemical Works under federal contract from 1942 to 1957 for uranium-compound processing, machining, and uranium metal recovery; and the St. Louis North County Sites, encompassing the St. Louis Airport Site (SLAPS) and SLAPS Vicinity Properties, which were used for decades to store various residues generated by Mallinckrodt uranium processing.
The contracted operations encompass “any and all remediation work,” including field engineering, radiological and safety support, cleanup of contaminated soil, and management services, according to the solicitation. It would primarily involve extraction of of low-level radioactive material. The contamination largely consists of thorium, radium, and uranium, along with cadmium, arsenic, and other nonradioactive substances.
