EPA Celebrates 50 Years of Protecting Drinking Water under Safe Drinking Water Act

The EPA celebrates the 50th anniversary of the Safe Drinking Water Act, which has improved water safety and public health for millions of Americans.

The U.S. Environmental Protection Agency (EPA) is commemorating the 50th anniversary of the Safe Drinking Water Act (SDWA), a law passed in 1974 to establish federal standards for drinking water quality. The landmark legislation has been instrumental in improving public health and addressing water contamination issues across the United States.

“For 50 years, EPA has worked with states, Tribes, and local partners to ensure that communities across the country can count on safe drinking water. As a result, Americans are leading longer, healthier lives while the foundation of safe drinking water attracts businesses to communities and fosters opportunity,” Bruno Pigott, deputy assistant administrator for EPA’s Office of Water, said in a statement. “The Safe Drinking Water Act provides a framework for developing collaborative solutions to address drinking water challenges of today and tomorrow.”

Before the SDWA, there were no comprehensive federal regulations for drinking water, leaving millions vulnerable to waterborne illnesses. Between 1961 and 1970, officials recorded over 46,000 cases of hepatitis, salmonellosis and gastroenteritis caused by contaminated water. Since its inception, the SDWA has limited harmful contaminants and provided funding for infrastructure to ensure compliance with water quality standards.

The EPA continues to expand protections under the SDWA. In October, the agency finalized the Lead and Copper Rule Improvements, a measure aimed at replacing toxic lead pipes nationwide. In 2024, the EPA also established the first-ever drinking water standards for PFAS, or “forever chemicals,” which are estimated to protect nearly 100 million people from exposure.
