Notice of LEHR CERCLA Five-Year Review

The U.S. Department of Energy (DOE) Office of Legacy Management (LM) is conducting the third five-year review of the ongoing protectiveness of selected remedies for environmental impacts within DOE areas of the Laboratory of Energy-Related Health Research (LEHR) at the University of California – Davis. Under the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA), DOE successfully resolved several significant impacts to human health and the environment at LEHR. However, residual contaminants at the site prevent unrestricted use of some areas and have the potential to impact groundwater quality in the future.

The selected remedies for DOE area are:

•    Land-use restrictions, including a soil management plan (SMP) and the prohibition of residential use in selected areas.
•    Long-term groundwater monitoring.
•    Contingency remediation.

The review ensures that CERCLA remedies continue to protect human health and the environment. The review team will inspect site reports, monitoring and inspection data, and monitoring and surveillance practices. The review team will also conduct a physical inspection of the site and interviews with stakeholders, and will collect comments and concerns regarding remedy effectiveness and administration of the site. The review began in October 2024 and will conclude in early 2026. Previous five-year reviews, additional LEHR documents, and other site information is available on this webpage.
