The Environmental Protection Agency oversees environmental health in the United States, as of 2015. The mission of the organization is to protect the environment itself and to protect people from environmental health hazards.
The U.S. Environmental Protection Agency writes regulations after Congress passes environmental laws. The agency also sets national standards that are enforced on state and tribal levels, assists state and local governments with implementation, and enforces environmental laws and standards. The agency also grants funds to state environmental programs, nonprofit organizations and educational institutions to engage in activities such as environmental cleanups and research. The U.S. Fish and Wildlife Service and the Department of Energy Office of Environmental Management address specific areas of environmental health, such as the Endangered Species Act and nuclear waste, respectively.
