This page summarizes public records reviewed by this site. It does not replace official notices, utility updates, or state drinking water information.

System profile limitations

  • This profile identifies PETERSBURG, PWSID AK2130148, as an active community water system using surface water. It does not confirm the provider for an address or prove that city boundaries match the service area.
  • The reviewed official sources list three different population values: 3,045 in the 2025 report, 3,218 in Alaska DEC's February 2026 summary, and 3,350 in the EPA record retrieved July 22, 2026. This profile does not select or publish one of those values.
  • No service-connection count is published because the reviewed sources do not provide a sufficiently current, reconciled value for this profile.
  • The two result cards preserve source-period values from the official 2025 annual report. They are not a present-day safety finding, current compliance determination, or measurement at a particular household tap.
  • The system preview intentionally shows two source-period rows. The linked 2025 annual-report page accounts for all 15 reviewed table rows, including action-level, below-reporting-limit, non-regulatory, and treatment-technique results.
  • Alaska DEC's February 10, 2026 monitoring summary lists a sanitary-survey corrective action due June 1, 2026. The reviewed snapshot does not say whether the action was completed by that date, and this profile does not infer current status.
  • The Petersburg Borough news archive is not a live advisory feed and cannot prove that no current notice exists. Check current Petersburg Borough and Alaska DEC sources for time-sensitive instructions.
  • Annual water quality reports summarize a reporting period. They are not live status pages and do not determine conditions at a specific tap.
  • Address-level service can vary. Confirm the serving provider with a bill, account portal, utility, city, or state source.
  • This page shows summarized entries from the available report. It does not include a complete contaminant or violation table.
  • Missing fields are not findings. They mean the field is not shown on this page from the records currently available.
