Formerly Used Defense Sites (FUDS)

Formerly Used Defense Sites (FUDS) are locations once owned or used by the U.S. military for training, testing, or other activities that may have left behind hazardous substances. These sites are not currently active military property but may pose environmental or health risks due to contamination. The U.S. Army Corps of Engineers often oversees the assessment and cleanup of FUDS to ensure they are safe for future use, whether for recreation, development, or conservation. The FUDS program helps manage historical military sites responsibly, restoring areas impacted by past military operations.
