Summary
Fourth Five-Year Review Completed
The U.S. Environmental Protection Agency (EPA) Region 7 has completed the Fourth Five-Year Review for the 29th & Mead Groundwater Contamination Superfund Site (site) in Sedgwick County, Kansas. Trichloroethylene is one of the main contaminants of concern. Five-year reviews (FYRs) 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. FYRs provide an opportunity to evaluate the site remedy to determine whether it remains protective of human health and the environment.
The remedy at the Coleman Operable Unit of the site is protective of human health and the environment in the short-term through removal of contaminants by soil vapor extraction (SVE) systems. Contaminated groundwater is treated via two groundwater extraction wells. Long-term protectiveness will be achieved through the establishment of an Institutional Control for contaminated soil; verification of hydraulic containment by the groundwater remedial system; evaluation of the effectiveness of the SVE systems; and evaluation of the characterization of soil sources. This FYR was completed in September 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 FYRs and Administrative Records for this site are available on EPA’s website. (Click on Site Documents & Data; see Reports and Documents for FYRs.)
EPA encourages community members to ask questions and report any concerns about this site. Questions or requests for site information and/or the FYR process can be submitted to:
