Missouri & Illinois Industrial, Chemical & Refinery Sites
St. Louis's chemical and industrial corridor was one of the most concentrated in the nation. Monsanto, Mallinckrodt, Wagner Electric, Anheuser-Busch, and the Illinois side's steel mills and refineries at Alton, Granite City, and Roxana all used asbestos-containing materials extensively from the 1930s through the 1980s. Missouri workers crossed the river regularly — their exposure histories cross state lines, and so do their claims. Click any site to read its full exposure history.

Illinois Industrial & Refinery Sites
Illinois law applies to these facilities.

Missouri residents who worked at Illinois industrial sites frequently have claims under both states' laws simultaneously depending on which compensation avenue is pursued.
