Cleaning up contaminated sites: Department of Energy nuclear sites, Superfund sites, former defense sites, munitions response and military base cleanups. The Department of Energy's environmental management program and the Army Corps of Engineers are among the largest buyers.
Set-asides: at least 9% of FY2026's remediation contract dollars ($509.44M) went through contracts set aside for small businesses, most through small business and 8(a) set-asides. Many orders under larger contracts carry no set-aside code, so this counts only what is reported. How set-asides work →
