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

  • Stale recordThe newest sample is older than the freshness window, so the profile may be out of date.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.
