Beneath one of Washington, D.C.'s most prestigious neighborhoods lies a toxic legacy few Americans know about. In this chilling episode, we uncover the forgotten history of Camp Leach, a secret World War I-era chemical weapons testing site buried under what is now American University and the upscale homes of Spring Valley.

From mustard gas to arsenic, and from patriotic experiments to environmental catastrophe, the story of Camp Leach is as unsettling as it is unknown. We trace its origins during the Great War, the deliberate cover-up that followed, and the terrifying rediscovery in the 1990s that triggered one of the most expensive and dangerous cleanup efforts in U.S. history. This is not just a local story; it's a national warning.

Topics Covered:

• The rise of chemical warfare during World War I

• How American University became a chemical weapons hub

• The environmental disaster buried under Spring Valley

• The 1993 rediscovery and 25-year cleanup

• Public accountability, government silence, and historical amnesia

• How Camp Leach fits into a larger pattern of buried wartime secrets across the U.S.
