Region 9 Drinking Water Health Advisories and Advisories Table (PDF) (30 pp, 621K, About PDF) Updated Nov 2009
The quality of drinking water delivered to consumers in the United States is one of the best in the world. Ensuring the provision of safe drinking water to the public is one of the Agency’s highest priority public health goals. Each day, water utilities and governments at all levels work together toward that goal.
Congress passed the Safe Drinking Water Act (SDWA) in 1974 to protect public health by regulating the nation’s public drinking water supply and protecting sources of drinking water.
EPA establishes enforceable health standards for contaminants based on monitoring and reporting by public water systems and provides financial and technical assistance to states and tribes to carry out national requirements.
