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 Total Trihalomethanes and source-labeled Total Haloacetic Acid (THAA) from page 15 of the 2025 report. The table has no violation or compliance column, so this profile does not infer one.
  • Two rows from the report's treated-water tables are modeled. The remaining regulated, operational, Lead/Copper, radiochemical, UCMR5, source-water, and educational sections are not reproduced in this preview.
  • The 2025 report supersedes the separately retained 2024 report as the latest source used by this profile. Annual values describe a reporting period and are not a live status page.
  • The report's Nitrate, Total Coliform, Lead/Copper, radiochemical, and UCMR5 layouts contain source tensions or require additional interpretation. They are intentionally excluded rather than normalized into stronger claims.
  • Connecticut DPH lists Middlebury, Prospect, Waterbury, Watertown, and Wolcott among the towns served. The Waterbury relationship supports navigation only and does not prove the provider for every address.
  • Use Alert Waterbury, the Water Department, and Connecticut DPH for time-sensitive instructions. This site does not assert that an advisory is or is not 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.
