Impacted Areas

The July 2025 expansion of the Radiation Exposure Compensation Act (RECA) brings long-overdue recognition to numerous Missouri communities impacted by radioactive contamination.

Many of these areas share ZIP codes newly deemed eligible under RECA due to their proximity to radioactive waste sites, such as Coldwater Creek, West Lake Landfill, and historical transport routes from the Downtown St. Louis Mallinckrodt and Weldon Spring uranium processing sites.

While some locations are confirmed in legislative documents, others remain under review—highlighting the urgency for continued advocacy, documentation, and community mobilization to ensure full inclusion and support.

St. Louis City

Contamination in St. Louis City is primarily linked to the Mallinckrodt Chemical Works. The RECA expansion includes ZIP codes covering the North Riverfront and Near North Riverfront neighborhoods.

St. Louis County

Many communities in St. Louis County were impacted by waste from sites like Coldwater Creek and the West Lake Landfill. The expansion covers numerous municipalities throughout the county.

St. Charles County

The Weldon Spring site is the primary source of contamination affecting St. Charles County. Several ZIP codes in and around the area are now included under RECA.
