Dioxin Contamination Forced Relocation of Missouri Town

Times Beach, a small town in Missouri, faced a devastating environmental crisis stemming from a well-intentioned, yet ultimately hazardous, dust control measure. In the 1970s, the town opted to spread residual oil on its unpaved roads to mitigate dust kicked up by traffic. However, this oil was later found to be contaminated with dioxin, a highly toxic substance.

The source of the contamination was waste from a chemical plant in Verona, Missouri. Industrial oil haulier Russell Bliss was hired to dispose of this waste, which contained 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD). Bliss mixed this toxic material with waste oil and applied it across numerous locations in Missouri, including the streets of Times Beach.

Early signs of the dioxin's toxicity emerged in 1971, with reports of horses, birds, dogs, and cats dying at Shenandoah Stables, a site where Bliss had applied the mixture. A young girl also fell seriously ill, with subsequent investigations linking these incidents to dioxin exposure.

The situation dramatically worsened in December 1982 when the Meramec River flooded, inundating Times Beach. While the floodwaters did not cause the contamination, they raised fears that the dioxin-laced material could spread further throughout the municipality. Consequently, federal authorities advised residents against returning to their homes. This led to a definitive decision on February 22, 1983, when the EPA, FEMA, and the state of Missouri announced a permanent relocation plan for the town's approximately 2,000 residents, costing $33.1 million to protect their lives.
