Policymakers have implemented a number of regulations over the past half-century to ensure a safe relationship between people and their environment. Under the Clean Air Act, the Environmental Protection Agency regulates air pollution. Similarly, the Clean Water Act and Safe Drinking Water Act ensure that states properly dispose of pollutants at treatment plants and that public drinking water meets federal standards.

These laws not only help preserve the nation's natural resources, but they protect the public from harmful toxins and resulting health concerns.
