Safe Drinking Water Act

Definition

The Safe Drinking Water Act (SDWA) is a federal law in the United States that aims to protect public health by regulating the nation's public drinking water supply. This law establishes standards for water quality and safety, ensuring that the water people consume is free from harmful contaminants. It emphasizes the importance of clean and safe drinking water and mandates regular testing and treatment of public water systems to minimize health risks associated with waterborne pollutants.
