What following means

  1. Published-record changes

    Updates are tied to the public record you name, not a claim about conditions at your household tap.

  2. Relevant notifications

    Updates cover new evidence, a material finding change, or an important methodology update, not generic promotional email.

  3. Email-only access

    Following does not require an account or a login. Updates arrive by email, and every message includes an unsubscribe link.
