National Research Programs

Chemical Safety Research

Developing tools to evaluate the potential of pesticides and industrial chemicals to hurt people and wildlife.

More about the Chemical Safety  Research Program >>

Clean Air Research

Assessing the health and environmental impacts of clean air regulations. Issues include: ozone, particulate matter, and multi-pollutant approaches.

More about the Clean Air Research Program >>

Climate Change Research

Studying how global change--particularly in our climate -- affects air and water quality, ecosystems, human health, and socioeconomic systems. Providing information to decision-makers to help adapt to a changing climate.

More about the Climate Change Research Program>>

Computational Toxicology Research

Integrating innovative computing and information technologies with molecular biology to develop decision support tools for assessing chemical exposure, hazard and risk. Coordinating research on chemical screening and prioritization, informatics and systems modeling.

More about the Computational Toxicology Research Program >>

Water Research

Developing sustainable solutions to 21st century water resource problems, ensuring water quality and availability in order to protect human and ecosystem health.

More about the Water Research Program >>

Ecosystem Services Research

Investigating how to protect and restore ecosystem "services:" life-sustaining benefits we receive from nature. Examples include clean air and water, fertile soil for crop production, pollination, and flood control.

More about the Ecosystem Services Research Program >>

Homeland Security Research

Securing and sustaining water systems; characterizing contamination and determining risk; and remediating indoor and outdoor environments in the event of biological, chemical, or radiological contamination.

More about the Homeland Security Research Program >>

Human Health Research

Assessing risks to people's health from environmental pollutants. Developing biological indicators to determine how regulatory decisions affect public health.

More about the Human Health Research Program >>

Human Health Risk Assessment

Providing citizens and regulators with information about pollutants or naturally occurring compounds that are linked to respiratory illnesses, cancers, cardiac disease, birth defects, neurological impairments and other health problems.

More about the Human Health Risk Assessment Program >>

Land and Waste Management Research

Developing ways to preserve land, restore contaminated properties, and protect the public from contaminants. Issues include: contaminated sediments, groundwater contaminant transport and remediation, and mine waste technology.

More about the Land and Waste Management Research Program >>

Nanotechnology Research

Studying the unique properties of nanomaterials, determining their potential impacts, and developing approaches to evaluate any risks. Exploring how nanomaterials can be used effectively to clean up contaminants released into the environment.

More about the Nanotechnology Research Program >>


Making sustainability the next level of environmental protection by drawing on advances in science and technology, applying government regulations and policies to protect public health and welfare, and promoting green business practices.
