About the Health and Environmental Risk Assessment Research Program

What We Do

EPA’s Health and Environmental Risk Assessment (HERA) Research Program is designed to develop and apply state-of-the-science research to characterize the impacts on human and ecological systems, whether they result from exposure to single, complex, or multiple physical, chemical, or biological stressors. In doing so, HERA provides key components of the scientific foundation for risk assessments to inform decisions aimed at protecting human health and the environment.
