What is EPA’s role in ensuring drinking water remains safe?

EPA has established regulations with treatment requirements for public water systems that prevent waterborne pathogens such as viruses from contaminating drinking water. These treatment requirements include filtration and disinfectants such as chlorine that remove or kill pathogens before they reach the tap. Additionally, the World Health Organization (WHO) Exit notes that, “conventional, centralized water treatment methods which utilize filtration and disinfection should inactivate COVID-19 virus.”

EPA will also continue to coordinate with our federal partners, including the Centers for Disease Control and Prevention (CDC), and will continue to provide technical assistance and support to states, as appropriate.
