In the fall of 1982, Times Beach residents learned that oil used to spray the town’s many dirt lanes had been laced with dioxin, a toxin deadly to animals, and the U.S. Environmental Protection Agency began taking samples. On Dec. 6, 1982, the Meramec River crested 24 feet above flood stage, and the one-two punch of dioxin and floodwater sealed Times Beach's fate. It was never occupied again.
