About EPA

About the National Risk Management Research Laboratory (NRMRL)

What We Do

As EPA’s premiere laboratory for risk management research, NRMRL focuses on environmental problem-solving. Recognized as a national leader in scientific and engineering expertise and capability, NRMRL’s research portfolio spans the five goals outlined in EPA’s Strategic Plan, and directly supports efforts to reduce greenhouse gas emissions, improve air quality, manage chemical risks, clean up hazardous waste sites, and protect America's water.

Environmental risk management seeks to determine what environmental risks exist and how to manage those risk in a way best suited to protect human health and the environment. Our mission is to advance scientific and engineering solutions to manage current and future environmental risk.
