Superfund Removal Actions (Cleanups)
In 2007, Dow cleaned up four dioxin hot spots in the Tittabawassee and Saginaw Rivers downstream of Dow's plant in Midland. In July 2008 Dow began cleaning up dioxin contaminated yards, homes, and paving road surfaces in the Riverside Boulevard neighborhood of Saginaw. Both cleanups were done with EPA oversight. Residential yards were dug up and backfilled with clean soil, interiors of homes were cleaned, and surfaces on Riverside Boulevard were paved.
