Source report notes

Source: Tacoma Water 2025 Water Quality Report. Retrieved 2026-07-31.

  • Applies to: Nitrate

    The source prints 4.0 ppm (2025), range 0-4.0 ppm, and Regulation met: Yes. The Yes is retained only as report-period wording. Annual-report values and printed status describe only the cited report and sample period. They are not a current compliance feed, advisory determination, address-level result, household-tap result, or safety conclusion.

  • Applies to: Total Trihalomethanes

    The separate Bonney Lake/Falling Water table on page 6 is excluded. The source prints N/A for MCLG and Regulation met: Yes; neither is converted into a present-day conclusion. Annual-report values and printed status describe only the cited report and sample period. They are not a current compliance feed, advisory determination, address-level result, household-tap result, or safety conclusion.

Review the linked source report for definitions, footnotes, and official wording.

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

  • The bounded preview shows only Nitrate and Total Trihalomethanes from Tacoma Water's main table on physical PDF page 5. Each printed Regulation met: Yes value applies only to the 2025 report context.
  • The separate Bonney Lake/Falling Water subdivision table on physical PDF page 6 is quarantined and is not Tacoma system row evidence.
  • Address-level service can vary. Confirm the serving provider with a bill, account portal, utility, city, or state source.
  • Tacoma Water serves a wider area and works with partner systems. The Tacoma relationship supports navigation but does not prove universal coverage, exact service boundaries, or the provider for an address.
  • The linked water-events map is dynamic. Planned flushing observed on July 31 is not presented as a water-quality notice, and this profile does not claim that no current notice exists.
  • Provider safety or compliance marketing in the annual report is not reproduced or treated as current status.
  • 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.
