What USEPA regulation requires consumer confidence reports to be provided to its customers?

• A. Public Notification Rule
• B. Contaminant Monitoring Rule
• C. SDWA, 1996 Amendment
• D. Surface water Treatment rule, 1975

Answer: (C)

The requirement to provide an annual report to customers about drinking water quality comes from the amendments to the Safe Drinking Water Act enacted in 1996. These amendments established the Consumer Confidence Report program, mandating public water systems to prepare and deliver to customers a yearly report that summarizes water quality data, detected contaminants, compliance with standards, and how customers can obtain more information. That direct link to informing customers about water quality is why this option is the best pick.

The other options relate to different parts of drinking water regulation. The Public Notification Rule focuses on timely alerts when a system fails to meet standards or poses a health risk, not the routine annual summary. The Contaminant Monitoring Rule deals with what contaminants must be monitored and how often. The Surface Water Treatment Rule from 1975 sets treatment requirements for surface water sources. None of these establish the annual Consumer Confidence Report requirement that the 1996 SDWA amendments do.
