About the company
County of Williamson, a U.S. local government entity headquartered in Marion, Illinois, serves federal agencies primarily as a prime recipient of federal grants and as a provider of forensic autopsy and pathology services to the Bureau of Prisons. The county operates as a government entity without SBA set-aside designations, competing on specialized capability and past performance rather than socioeconomic status; 73% of its recent federal awards are prime (grants and contracts), while 27% are sub-awards.
The county's federal footprint is heavily concentrated in two distinct service lines. The first is forensic autopsy services to the United States Penitentiary Marion under the Department of Justice Bureau of Prisons, which accounts for 15 purchase-order awards totaling $30 thousand in combined potential value across the last four years. These are repeat, low-dollar engagements ($1,953 to $3,138 per autopsy) dating to at least June 2022, with the most recent award issued July 5, 2026 for $2,600. The second is federal grant work. The county received a $1.355 million Cooperative Agreement from the Department of the Interior Fish and Wildlife Service (CFDA 15.654, National Wildlife Refuge System Enhancements program) awarded July 15, 2025, to design and construct approximately 6 miles of paved multimodal trail within the Crab Orchard National Wildlife Refuge, with completion slated for July 14, 2029. The county also received a $140 thousand Project Grant from the Department of Transportation's Safe Streets and Roads for All program (CFDA 20.939) on February 27, 2024, for development of a Comprehensive Safety Action Plan addressing roadway safety and fatalities across Williamson County.
The county also acts as a sub-recipient on federal transportation and victim-assistance grants managed by the Illinois Department of Transportation and the Illinois Criminal Justice Information Authority. Sub-recipient work includes engineering and right-of-way acquisition for roundabout design projects (2023, 2023) and law enforcement / prosecutor-based victim assistance services (2022, 2024).
Activity trajectory is modest and variable: two awards in 2022, four in 2023, seven in 2024, and one each in 2025 and 2026. Only one award faces recompete in the next twenty-four months, carrying $3 thousand in combined potential value. The county's organizational structure includes a named subsidiary, Devils Kitchen Water District, also registered as a U.S. local government entity.
