Wyoming's PFAS contamination is concentrated around F.E. Warren Air Force Base near Cheyenne and potential sources from the state's energy industry. F.E. Warren AFB, a strategic nuclear missile facility, has documented soil and groundwater contamination from firefighting foam use, affecting the South Platte River watershed and threatening Cheyenne's water supply system. The base's critical national security mission and decades of operations have created contamination requiring specialized remediation approaches.

Wyoming's oil, gas, and coal industries have potential PFAS sources from drilling operations, power plants, and industrial facilities. The state's location at the headwaters of major river systems, including the Colorado, Missouri, and Columbia Rivers, creates responsibilities for protecting water quality for downstream communities across the western United States. Wyoming's arid climate and high altitude create unique technical challenges for contamination assessment and remediation.

Key Facts

  • F.E. Warren AFB contamination affects South Platte River and Cheyenne water supply
  • Energy industries create potential sources from oil, gas, and coal operations
  • Headwater location creates downstream protection responsibilities across western US
