Source report notes

Source: Meriden Water Department 2025 Annual Water Quality Report. Retrieved 2026-07-15.

  • Applies to: Nitrate

    Violation: No is preserved only for the source's 2025 Nitrate row and is not a current compliance, advisory, or safety conclusion.

  • Applies to: Chlorine

    The source prints 4 and 4 in its MCL/MCLG columns for this disinfectant row; the preview preserves disinfectant-limit semantics and limits Violation: No to the 2025 row period.

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 Chlorine from the 2025 report. Violation: No is limited to those annual rows and is not a complete violation inventory or current compliance conclusion.
  • Two of twenty-five material table rows are modeled. The remaining inorganic, radioactive, microbial, volatile-organic, unregulated, and orthophosphate context is not reproduced in this preview.
  • Connecticut DPH lists surface water as the primary source, while the annual report also describes reservoirs, six groundwater wells, and occasional purchased water. This profile does not imply a surface-only supply.
  • The source contains internal table tensions, including Total HAAS ranges, Chloride maximum/range values, and Iron maximum/range values. They are intentionally not normalized into stronger claims.
  • A May 27, 2025 monitoring/reporting notice concerning April 2024 remains posted. The notice says the incident was not an emergency and gives an expected resolution date, but this site does not infer whether it is currently active or resolved.
  • Connecticut DPH lists Berlin, Cheshire, Meriden, Southington, and Wallingford among the towns served. The Meriden relationship supports navigation only and does not prove the provider for every address.
  • 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.
