About the Health and Environmental Risk Assessment Program

What We Do

The Health and Environmental Risk Assessment (HERA) Program at EPA is focused on advancing the understanding of the effects that exposure to pollutants have on key biological, chemical, and physical processes that affect human health. What EPA scientists and their partners learn provides the foundation for the Agency’s actions to protect public health and the environment.
