Ecosystems
Methods, Models, Tools, and Databases


EPA's ecosystems research is working to protect ecosystems and the air and water resources that provide numerous benefits for humans and other living things.

Health
Methods, Models, Tools, and Databases


EPA research is helping communities and policymakers develop and implement policies and practices to improve public health, especially for vulnerable groups such as children, the elderly and the socioeconomically disadvantaged.

Homeland Security
Homeland Security
Methods, Models, Tools, and Databases


Following the terrorist events of September 11, 2001 and the mailing of anthrax contaminated letters later that year, EPA's mission broadened to include protecting human health and the environment from the effects of biological, chemical, and radiological contamination due to homeland security events.

Land and Waste Management
Methods, Models, Tools and Databases


EPA is working to develop methods and guidance to manage and clean up contaminated land, ground water and nutrient pollution as well as develop innovative approaches to managing materials and waste including energy recovery.

Human Health Risk Assessment
Methods, Models, Tools and Databases


EPA uses risk assessment to characterize the nature and magnitude of health risks to humans and animals from chemical contaminants and other stressors that may be present in the environment.

Sustainability
Methods, Models, Tools and Databases

EPA efforts in the area of sustainability practices and approaches include labeling green products and promoting green chemistry and engineering, managing materials rather than creating waste, using green infrastructure to manage storm water runoff, and supporting the sustainable design of communities.
