Source report notes

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

  • Applies to: Nitrate

    The source prints separate Miami Plant and Ottawa Plant Highest Level Detected values of 1.71 and 1.44, ranges <0.10-1.71 and 0.92-1.44, and Violation No for each plant. The plant columns remain separate and are not flattened into one systemwide value. Annual-report values and printed status describe only the cited 2025 report or sample period. They are not a current compliance feed, advisory determination, address-level result, household-tap result, exposure conclusion, or safety conclusion. The reviewed relationship does not identify the provider for an address or prove exclusive service.

  • Applies to: Chlorine

    The source prints Highest Level Detected 1.29 with marker 3, Range of Detection 1.21-1.37, Violation No, and Year Sampled 2025. Footnote 3 says Highest running annual average. Annual-report values and printed status describe only the cited 2025 report or sample period. They are not a current compliance feed, advisory determination, address-level result, household-tap result, exposure conclusion, or safety conclusion. The reviewed relationship does not identify the provider for an address or prove exclusive service.

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 Chlorine from physical PDF page 3. Other regulated rows, the report-wide compliance banner, unregulated/PFAS rows, license statements, health language, lead context, and service-line narrative are not reproduced.
  • Address-level service can vary. Confirm the serving provider with a bill, account portal, utility, city, or state source.
  • The Chlorine row preserves Highest Level Detected 1.29³, range 1.21-1.37, and physical-page-4 footnote 3, Highest running annual average.
  • Each selected row prints Violation No for 2025. That field remains row/report-period context and is not converted into present-day compliance, advisory, exposure, household-tap, or safety language.
  • EPA's mutable SW source code is not silently reconciled with the municipal report's groundwater description.
  • The current-news item concerns recreational access during construction and is not represented as a drinking-water advisory. Its presence does not prove absence of another notice.
  • Official City and EPA evidence supports bounded Dayton navigation, but it does not prove exclusive 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.
  • This page summarizes available public records. It may not include every update, notice, or urgent official advisory.
