The U.S. Environmental Protection Agency (EPA) Region 7 has completed the Fifth Five-Year Review for the Findett Corp./Hayford Bridge Road Groundwater Superfund Site in St. Charles, Missouri. Five-Year Reviews are required by the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA) when hazardous substances remain on-site above levels that permit unrestricted use and unlimited exposure. Five-Year Reviews provide an opportunity to evaluate the site remedy to determine whether it remains protective of human health and the environment.
EPA has determined that the protectiveness determinations for Operable Units 01 and 02 cannot be made until additional soil samples are collected in areas of a previous removal action to determine if soil levels are below ecological and human health risk levels. EPA will continue to work with the responsible parties to collect additional soil samples, monitor groundwater, and study and evaluate site conditions. The remedy for Operable Unit 03 continues to be protective of human health and the environment through Monitored Natural Attenuation, and long-term protectiveness of the remedial action will continue to be verified through biennial sampling of downgradient groundwater. This Fifth Five-Year Review was completed in July 2020.
EPA has assessed the ability of the public to access site information through an internet-based repository and has determined that the local community has this ability. As a result, the Five-Year Reviews (see Reports and Documents) and Administrative Records for this site are available through this website: www.epa.gov/superfund/findett-hayfordbridgeroadgroundwater.
EPA encourages community members to ask questions and report any concerns about this site. Questions or requests for site information and/or the Five-Year Review process can be submitted to:
