Important limitation

Profile summary note

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

  • Official Alaska DEC and utility sources identify this record as Ketchikan Public Utilities, PWSID AK2120232; the 2025 report prints numeric system number 2120232.
  • The 2025 report describes Ketchikan Lakes and Granite Creek drainage as the raw surface-water source and outlines chlorine, ultraviolet-light, and chloramine treatment before distribution.
  • This page summarizes exactly two selected 2025 report entries. Open the linked report for the complete tables, definitions, footnotes, and other report-period context.
  • The 2025 report marks No in its MCL-violation column for the six listed rows. That is report-period information, not a current advisory or complete compliance-history check.
  • The 2025 report says KPU inspected 307 of its oldest services and found those inspected services to be non-lead. This does not establish plumbing or service-line material at a specific property.
  • KPU describes a bounded municipal service area and identifies nearby areas served by other public or private systems. Confirm service for an address with an official utility account or KPU.
  • EPA's dated 2026Q2 SDWA row and Alaska DEC's February 10, 2026 monitoring summary agree on 8,937 people served; an older undated Envirofacts view returns 8,652. This page uses the newer dated value and keeps the discrepancy visible.
  • EPA's dated 2026Q2 row lists this as a community water system with 2,783 service connections. Population and connection counts are system inventory context, not city population or proof of service for an address.
  • EPA's 2026Q2 extract contains older resolved or archived enforcement records. Annual-report and historical federal records do not establish current advisory or violation status.
  • The reviewed 2025 annual report summarizes a reporting period. It is not a live status page.
  • This system profile does not replace official utility, Alaska DEC, or local public-health notices and does not determine whether water at a specific tap is safe.
  • The linked Ketchikan relationship is reviewed city context only and does not confirm the provider for any address.
  • 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.
  • This page summarizes available public records. It may not include every update, notice, or urgent official advisory.
