EPA Region 7 has concluded after considering new soil sampling data and new toxicity information for dioxin that the cleanup conducted in the 1990s at the Route 66 State Park near Eureka, Mo., remains protective of human health and the park's current uses can continue.
Route 66 State Park was established by the State of Missouri in 1999 at the former town site of Times Beach, Mo., following a dioxin cleanup by EPA and MDNR.
For the June 2012 sampling at Route 66 State Park, EPA collected surface soils from a variety of representative locations, including trails, shelters, picnic areas, the playground, the proposed location for an off-leash dog park, underground utility line installation areas, former roadways and residential lots, and two outfalls near the Meramec River.
