Rock Island County — Rock Island, Moline, and East Moline — is the Illinois half of the Quad Cities, anchored by the Rock Island Arsenal, the John Deere Harvester Works, and the Rock Island Railroad shops, where military manufacturing, farm-equipment foundries, and locomotive work reportedly relied on asbestos-containing insulation and materials for generations of workers.

Illinois allows two years from a mesothelioma or asbestos-cancer diagnosis to file a personal-injury claim (735 ILCS 5/13-202), paired with a two-year wrongful-death deadline from the date of death (740 ILCS 180/2). Cases are filed in the county Circuit Court of proper venue.
