The U.S. Army Corps of Engineers, Kansas City District has completed a recurring review for the former Jefferson Barracks Post Dumping Grounds Military Munitions Response Program Site. The Jefferson Barracks was established in 1826 as a garrison for the U.S. Army infantry units. From 1826 to 1946, portion of the Jefferson Barracks riverfront property were used for various waste disposal activities, including World War I-era military munitions, such as mortar rounds.
