Fact Sheet:
Final Drinking Water Public Notification Regulations

EPA 816-F-00-020, May 2000

Questions and Answers

What is public notification?
Public notification is intended to ensure that consumers will always know if there is a problem with their drinking water. Public water systems must notify the people who drink their water if the level of a contaminant in the water exceeds Environmental Protection Agency (EPA) and State drinking water regulations, if there is a waterborne disease outbreak or any other situation that may pose a risk to public health, if the water system fails to test its water as required, or if the system has a variance or exemption from the regulations. Depending on the severity of the situation, water suppliers have from 24 hours to one year to notify their customers. EPA sets strict requirements on the form, manner, content, and frequency of public notices. Public notification is provided in addition to the annual water quality report (consumer confidence report, or CCR), which provides customers with a more complete picture of drinking water quality and system operations. The annual CCR tells consumers what's in their water, where it comes from, and where they can obtain additional information.

In fiscal year 1998, there were more than 124,000 violations of drinking water regulations requiring a public notice, involving over 25 percent of the 170,000 public water systems. Over 90 percent of the violations were for failure to fully meet the monitoring or testing procedure requirements. Fewer than 1.5 percent of the violations posed an immediate risk of adverse health effects from short-term exposure.

What action is EPA taking?
EPA published final regulations in the Federal Register on May 4, 2000 (65 FR 25981) to revise the general public notification regulations. The revised regulations require faster notice in emergencies and fewer notices overall, and will result in notices that better communicate the potential health risks from drinking water violations and how to avoid such risks. The new rule will enable water systems to better target notices to the seriousness of the risk and make the existing notification process less burdensome for water suppliers and make notices easier to read for consumers.

The revised regulations (under 40 CFR Part 141, subpart Q) are effective on June 5, 2000. However, they do not apply to public water systems in States with approved primacy programs until May 6, 2002, unless a primacy State chooses to adopt the new requirements earlier. Public water systems where EPA directly implements the drinking water program (i.e., Wyoming, Washington, D.C., and Tribal lands) must start complying with the new regulations on October 31, 2000. EPA proposed the public notification rule revisions on May 13, 1999 (64 FR 25963).

How does the final requlation work?
The final regulation divides public notice into three tiers:

Top of page

What types of violations and situations are covered under each tier?
The final regulation contains an Appendix listing out every violation and situation requiring a public notice and its tier. The requirements for the timing of the public notice and the form and manner of its delivery are determined by the tier to which the violation or situation is assigned. For example, a total coliform violation where fecal coliform is present falls under Tier 1, which requires notification delivery within 24 hours by (at a minimum) appropriate broadcast media, posting, or hand delivery.

What are EPA requirements for the form, manner, and content of the public notices?
The final rule sets minimum methods of delivery under each tier, but also requires that water systems take steps reasonably calculated to reach others not reached by the minimum method. Each notice must contain information addressing ten elements, including use of standard health effects language for maximum contaminant level (MCL) and treatment technique violations and standard language for monitoring violations. Public water systems serving a large proportion of non-English speaking consumers are also required to include information in the notice in languages other than English.

New Implementation Requirements

Which public water systems are affected by the regulation?
Once the rule goes into effect in each State, it will require all the public water systems to make changes to their current public notification programs to incorporate the revised regulations. The final rule will requir States with primary enforcement authority to revise their approved primacy programs to adopt regulations no less stringent than the revised EPA regulations. The final regulation gives States considerable discretion, at their option, to work with EPA to tailor public notification programs to fit unique needs, policies, and programs.

How is EPA helping public water systems with new requirements?
EPA and the Association of State Drinking Water Administrators (ASDWA) are issuing a Public Notification Handbook to assist water systems in implementing the revised regulation. This Handbook provide templates for notices and other aids to help water systems develop notices for violation situations.
