The SDWA includes several fundamental provisions: - Setting Standards: The EPA sets legally enforceable standards known as National Primary Drinking Water Regulations (NPDWRs) for contaminants that pose health risks. These standards are based on scientific research and risk assessments. - Monitoring and Reporting: Public water systems must regularly monitor their water supply and report findings to the state and the EPA. This ensures continuous surveillance of water quality. - Public Notification: In the event of contamination that exceeds the safety standards, water suppliers must notify the public and provide information on the health risks and steps to take to protect health. - Funding and Assistance: The SDWA provides financial assistance to local governments and water systems for improvements and upgrades to water infrastructure.
