Systems without a Water Profile stay in this list. Hiding them would make the record look more complete than it is.

Utility pages by state

Each page lists the utility's contact details beside its record.

  • No profile publishedThe system is in the register but its records haven’t been read. Not a pass, not a fail.
  • Stale recordThe newest sample is older than the freshness window, so the profile may be out of date.
  • Score withheldA profile exists but no score is published for it.
  • Service area unresolvedWe can’t yet tie the system to a PWSID or the places it serves.
