Summary

Sixth Five-Year Review Started

The U.S. Environmental Protection Agency (EPA) Region 7 has started the Sixth Five-Year Review for the Lehigh Portland Cement Co. Superfund Site. Five-Year Reviews are required by the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA), commonly known as Superfund, 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. This Five-Year Review Report should be completed by July 2027.

Site project information and previous Five-Year Reviews are available to the public at web repositories. To view cleanup documents, please visit EPA’s Site Profile page (see Site Documents & Data).
