Which method is used for Tier 3 public notification of a primary contaminant violation?

The use of mail or direct delivery, along with publication in a daily newspaper, is the standardized method for Tier 3 public notification regarding primary contaminant violations. This approach ensures that the information reaches a broad audience, including those who may not have access to digital platforms.

Publications in daily newspapers provide a tangible, official means of communication that is widely recognized and can reach diverse demographics, while direct mail guarantees that households receive the notification directly. This combined approach meets regulatory requirements for transparency and public awareness, allowing for an effective means of informing the community about serious water quality issues.

Other methods listed, such as social media or email notifications, do not provide the same level of guaranteed reach and may exclude individuals who rely on traditional media for important information. Television broadcasts, while possibly effective, may not have the same regulatory recognition or comprehensive reach as the combination of mail and newspaper publication.
