Source report notes

Source: Oklahoma City Water Quality Report 2025. Retrieved 2026-08-02.

  • Applies to: Lead

    00 ppb, MCLG 0, AL 15, qualitative All Sites < AL, and source-printed Compliance YES. The less-than qualifier is preserved. No range or numeric sites-over-action-level value is synthesized. This is systemwide sampling-distribution context, not a result for a particular tap. Annual-report values and printed status describe only the cited 2025 report period. They are not a current compliance feed, advisory determination, address-level result, household-tap result, exposure conclusion, or safety conclusion.

  • Applies to: Copper

    603 ppm, MCLG 0, AL 1.3, qualitative All Sites < AL, and source-printed Compliance YES. Copper remains in ppm. No range or numeric sites-over-action-level value is synthesized. This is systemwide sampling-distribution context, not a result for a particular tap. Annual-report values and printed status describe only the cited 2025 report period. They are not a current compliance feed, advisory determination, address-level result, household-tap result, exposure conclusion, or safety conclusion.

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 Lead and Copper from physical PDF page 5. Other report rows and health language are not reproduced in the preview table.
  • The Lead row preserves <1.00 ppb, and Copper remains 0.603 ppm. Each row prints qualitative All Sites < AL and Compliance YES. No numeric sites-over-action-level value or range is invented, and neither result describes a specific household tap.
  • The May 2025 coliform counts and percentages, annual occurrence, and printed Compliance YES remain report-period context. They do not establish present conditions or a current notice.
  • The report says its most recent source-water Cryptosporidium testing was in 2016-2017 and lists averages below 0.075 cysts/L. The old period remains visible and is not converted into a current risk or safety claim.
  • The report's zero-violation summary is scoped only to its 2025 report period and is not converted into a present-day compliance or no-notice conclusion.
  • Address-level service can vary. Confirm the serving provider with a bill, account portal, utility, city, or state source.
  • The municipal table prints plant identifiers 1020902 and 1020902B. The profile remains bound to exact EPA/repository PWSID OK1020902 and does not create or silently merge a second system identity.
  • Oklahoma City Water Utilities Trust describes service across 17 communities and says The Falls neighborhood receives Edmond water. The reviewed relationship does not prove exclusive citywide service or identify the provider for an 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.
