Source report notes

Source: City of Danbury Spring 2026 Water Quality Report. Retrieved 2026-07-15.

  • Applies to: Nitrate as nitrogen

    The Spring 2026 publication labels this as a 2025 data-table row. Limit Exceeded?: No is limited to that row and period; it is not a current compliance, advisory, or safety conclusion.

  • Applies to: Chlorine - distribution system average

    The report prints 4 and 4 under its MCL/MCLG columns for this disinfectant row and separately defines MRDL/MRDLG; both the printed columns and disinfectant semantics are disclosed. Limit Exceeded?: No is limited to the 2025 row period.

  • Applies to: Chlorine - distribution system average

    Table note: Value shown is an average of multiple results calculated to determine regulatory compliance.

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 linked Spring 2026 report primarily summarizes 2025 results and retains 2023 monitoring dates where printed. It is historical report-period evidence, not a live status page.
  • The bounded system preview intentionally shows only Nitrate as nitrogen and the Chlorine distribution-system average from the complete 22-row extraction. Limit Exceeded?: No is limited to those row periods and is not a current compliance conclusion.
  • The complete report route includes the other regulated, secondary, non-regulated, and PFAS rows; expanding the report does not expand this two-row system preview.
  • The report prints Manganese as exceeding a recommended limit, PFOA at 5.0 ppt against the report's printed 4.0 ppt EPA MCL, and a TTHM range reaching 86.0 ppb while the annual row says No. This profile preserves those omitted-source tensions without deriving a current violation or safety conclusion.
  • Spring 2026 is the annual-publication context; the previewed table primarily describes 2025 results and is not a live status page.
  • Connecticut DPH lists Bethel, Brookfield, Danbury, and Ridgefield among the towns served. The Danbury relationship supports navigation only and does not prove the provider for every address.
  • Danbury ALERT is a general city alert path rather than a dedicated drinking-water ledger. This site does not assert whether an alert is active.
  • This profile does not replace official utility, Connecticut DPH, or public-health notices and does not determine whether water at a specific tap is safe.
  • 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.
  • Address-level service can vary. Confirm the serving provider with a bill, account portal, utility, city, or state source.
