Why are federal Safe Drinking Water Act standards important to ADEQ?

• A. They determine the color of drinking water.
• B. They are optional guidelines.
• C. They apply only to bottled water.
• D. They set health-based contaminant limits and reporting requirements that state agencies implement to protect public health.

Answer: (D)

Federal Safe Drinking Water Act standards provide legally enforceable, health-based limits for contaminants and require regular monitoring and reporting. ADEQ uses these rules to regulate public water systems in the state, issuing permits, conducting inspections, and enforcing compliance. This framework helps ensure drinking water stays within safe levels and that the public receives timely information about water quality through required reports. It’s important to note that bottled water is regulated by the FDA, while the SDWA standards apply to public water systems that deliver tap water to consumers.
