The Bridgeton Sanitary Landfill is a solid waste landfill located within the boundaries of West Lake Landfill in the Greater St. Louis metropolitan area. From November 1985 to December 2004, municipal wastes were accepted under permit at Bridgeton Landfill, a 52- acre site that was originally a limestone quarry. Since 2010, a subsurface smoldering event (SSE) has been occurring at the landfill.

2022 Final Release of Health Consultation

Under a cooperative agreement with the Agency for Toxic Substances and Disease Registry (ATSDR), the Missouri Department of Health and Senior Services (DHSS) has written a public health consultation to evaluate the public health impacts of breathing gas and odor emissions from the landfill, which increased following the onset of the SSE.

In September 2018, the health consultation was released for public comment. In January 2019, during the public comment period, DHSS held a public meeting to discuss the findings of the health consultation. The final version of the document, released in August 2022, contains responses to public comments. As a result of comments received on the prior public comment version of the document, several revisions were made to the main body in this final document. The conclusions of this health consultation, however, did not change. Revisions were made to help clarify the public health assessment process and the findings of the report.

In this health consultation, DHSS does not address health concerns associated with radiological contaminants at West Lake Landfill. In 2015, ATSDR published a separate public health consultation on radiation in groundwater and air (see their website in Additional Resources below).
