About the company
ST John Environmental Consulting LLC, a service-disabled veteran-owned small business (SDVOSB) sole proprietorship based in St. Louis, Missouri, delivers environmental remediation, hazardous material inspection, and demolition services to federal agencies as a prime contractor (75% of recent awards) and as a subcontractor on environmental remediation work. The vendor holds active SBA certifications as both a veteran-owned small business and a service-disabled veteran-owned small business through April 27, 2027, and competes exclusively under SDVOSB set-asides on its prime work.
ST John's recent award footprint is narrow and project-focused. The Army Corps of Engineers Kansas City District anchors the portfolio with two awards totaling $1.5 million in combined potential value: a $1.165 million definitive contract awarded December 18, 2023, for non-hazardous demolition and disposal at the John Cochran VA Medical Center renovation project in St. Louis (covering six residential structures and one commercial building, with ultimate completion November 27, 2024), and a $350 thousand blanket purchase agreement awarded June 5, 2026, for hazardous material inspection services at Fort Leonard Wood, Missouri, running through June 4, 2031. The Department of Veterans Affairs Veterans Integrated Service Network 15 placed a $18 thousand SDVOSB set-aside definitive contract on June 16, 2026, for demonstration sinks to address Legionella deficiencies at a facility in Poplar Bluff, Missouri, with completion scheduled for October 18, 2026. On the sub side, ST John performed air-monitoring work as a subcontractor to Tarlton Corp beginning February 2, 2023, under a modification directing completion of multiple request-for-proposal line items.
Activity across the period captured in the source remains sparse — two awards in 2023 and two in 2026 — with one award ($18 thousand) facing ultimate completion inside the next twenty-four months and therefore exposed to recompete. The vendor's capability concentration spans remediation services, hazardous material inspection, and demolition, with geographic focus on Missouri facilities and military installations.
