Evolution of Federalism in Environmental Health: Federal, State, and Local Government Control.

Environmental health sits at the intersection of public health and environmental protection. Governments often confront environmental health concerns through environmental laws. Authority to take actions like passing these laws is determined by federalism, which divides the authority to make laws and policies on various issues between those levels of government. However, tensions often arise when these levels of government attempt to share regulatory authority over environmental issues. Issues of federalism are especially prevalent in environmental health issues, where incidents not only cross state and local borders and affect different levels of government but may also involve both environmental and health agencies. This article describes the history of environmental federalism in the United States through the lens of public health, including how the regulatory structure transitioned from primarily state control to a more centralized federal system of governance. It also describes modern federalism in environmental health, the levels of government involved in environmental health decisions, and the legal authorities that allow these governments to regulate environmental health in the United States. Finally, this article describes the implications of federalism in environmental health.
