From regulating auto emissions to banning the use of DDT; from cleaning up toxic waste to protecting the ozone layer; from increasing recycling to revitalizing inner-city brownfields, EPA's achievements have resulted in cleaner air, purer water, and better protected land.
The goal of EPA's ecosystems research is to provide scientific leadership and knowledge for assessing, improving, and restoring the integrity of ecosystems. EPA's goal includes protecting, sustaining and restoring the health of critical natural habitats and ecosystems. To accomplish this goal, EPA must assess the condition of the environment, diagnose causes of impairment and forecast the impact of alternative activities and policy scenarios. Ecosystems research provides scientific leadership and knowledge for assessing, improving, and restoring the integrity of ecosystems.
The goal of EPA's human health research is to improve our scientific knowledge base and to develop tools and methods to enable the Agency to identify and characterize human health impacts associated with environmental exposures.
From protecting and maintaining drinking water sources and public water systems, to protecting the ecological and biological integrity of the nation's wetlands and water ways, sustaining the nation's water resources is vital to maintaining human health our environment and our economy. EPA researchers are working to provide the scientific information and innovative technologies in support of the Clean Water Act and Safe Drinking Water Act. Research and technical assistance is focused on several major areas that include drinking water and water quality, wastewater, water resources, and water security.
EPA researchers are working to better understand climate change and how the effects will vary by region and over time, and how societies and the earth's environment will adapt to or cope with climate change. EPA's climate change research is focusing on those areas where EPA has the most to offer assessments of the consequences of climate change on air quality, water quality, human health and ecosystem health.
