The 1996 Amendments to the Safe Drinking Water Act included requirements for community water systems to distribute Consumer Confidence Reports (CCRs) to customers each year. These water quality reports must identify the drinking water source, and list detected regulated contaminants and certain unregulated contaminants. If a contaminant exceeds drinking water standards, the report will include the likely source and health effects of that contaminant and steps the water system is taking to correct the violation. If the water system has violated other regulations, the report must include that information. Some systems may be required to include an educational statement on nitrate, arsenic, or lead where the contaminants are detected at 50% above the EPA standard. The regulation also requires including telephone numbers for EPA's Safe Drinking Water Hotline, and the name and phone number of the water provider. Water providers are required to deliver CCRs to customers by July 1 of each year.

Public Notification Rule (2002)
Effective October 2002, this rule updates public notification requirements when water providers violate drinking water regulations. Notification requirements are generally faster in emergencies, fewer and simpler overall.
