Five-Year Review

2026

The U.S. Department of Energy has completed the fifth Five-Year Review for the Brookhaven National Laboratory (BNL) site, as required by the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA). This review serves to ensure that the implementation and performance of the selected cleanup remedies continue to be effective in protecting human health and the environment. This report reviewed the remediation work performed at the BNL site, including remediation of groundwater contamination on and off of BNL property, excavation and disposal of contaminated soils and river sediments, removal of above- and below-ground storage tanks, capping of landfills, decommissioning activities and long-term surveillance and maintenance at the former Brookhaven Graphite Research Reactor and High Flux Beam Reactor. Land-use restrictions and institutional controls are in place to ensure that any residual contamination is not dispersed and does not adversely affect human health or the environment. Information on the selected remedies at BNL as well as the status of remediation activities at the site is available on the BNL Groundwater Protection website.

2021

The U.S. Department of Energy is conducting a Five-Year Review for the Brookhaven National Laboratory (BNL) site, as required by the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA). This review serves to ensure that the implementation and performance of the selected cleanup remedies continue to be effective in protecting human health and the environment. This is the fourth site wide Five-Year Review of all the remediation work performed at the BNL site. This includes remediation of groundwater contamination on and off of BNL property, excavation and disposal of contaminated soils and river sediments, removal of above- and below-ground storage tanks, capping of landfills, decommissioning activities and long-term surveillance and maintenance at the former Brookhaven Graphite Research Reactor and High Flux Beam Reactor. Land-use restrictions and institutional controls are in place to ensure that any residual contamination is not dispersed and does not adversely affect human health or the environment. Information on the selected remedies at BNL as well as the status of remediation activities at the site is available on the BNL Groundwater Protection website.

2016

The U.S. Department of Energy has completed the third Five-Year Review for the Brookhaven National Laboratory (BNL) site, as required by the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA). This review serves to ensure that the implementation and performance of the selected cleanup remedies continue to be effective in protecting human health and the environment. This includes remediation of groundwater contamination on and off of BNL property, excavation and disposal of contaminated soils and river sediments, removal of above- and below-ground storage tanks, capping of landfills, decommissioning activities and long-term surveillance and maintenance at the former Brookhaven Graphite Research Reactor (BGRR) and High Flux Beam Reactor (HFBR). Land-use restrictions and institutional controls are in place to ensure that any residual contamination left in place is not dispersed and does not adversely affect human health or the environment. The U.S. Environmental Protection Agency concurs with the protectiveness determinations as reported within this Five-Year Review.
