Source report notes

Source: Missouri DNR 2025 Annual Water Quality Report - CITY OF COLUMBIA UTILITIES. Retrieved 2026-07-30.

  • Applies to: NITRATE-NITRITE

    No row-specific violation or compliance status is printed, so none is inferred. This report-period value is not a current advisory, safety, or tap-level conclusion.

  • Applies to: LEAD

    The value is the source's 90th-percentile result, not a tap sample. The report separately prints a July 2, 2025 lead-service-line notification reporting violation; that notice is disclosed on the system profile and is not assigned as this row's status.

  • Applies to: LEAD

    Footnote: 90th percentile: For Lead and Copper testing. 10% of test results are above this level and 90% are below this level.

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-NITRITE and LEAD from physical PDF page 2. Lead is a 90th-percentile action-level row, not an individual tap sample.
  • The City report page's lead-service-line notification reporting violation is disclosed separately and is not assigned as the status of either selected row.
  • The enriched report section preserves the extracted result groups, definitions, footnotes, and source limitations; the report remains historical evidence and does not establish household tap conditions.
  • Official provider and state links are supplied without claiming that the dated reporting matter is active, resolved, harmless, or representative of a household tap.
  • The Columbia relationship supports navigation only and does not prove exclusive coverage or the provider for every address.
  • 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.
  • This page summarizes available public records. It may not include every update, notice, or urgent official advisory.
