The printed Yes is scoped only to this 2025 row. This is reported annual-report evidence. It is not a present-day compliance, advisory, safety, address-level, or household-tap 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 Barium and Nitrate entry-point rows whose values and companion source/status columns span physical PDF pages 12 and 13. Other report content is not reproduced.
  • Hemlock Lake, Canadice Lake, and purchased Lake Ontario water are 2025 annual system-level source context. They do not determine current source allocation, provider identity for an address, finished-water condition, household-tap result, or safety.
  • Address-level service can vary. Confirm the serving provider with a bill, account portal, utility, city, or state source.
  • Physical PDF pages 10 and 11 say NYSDOH revoked the City's 1998 optimal-corrosion-control approval in April 2025 and issued a New York State Sanitary Code violation for failure to have optimal corrosion-control treatment in place. The report says this was not an emergency, attributes lead tap-sample results below the 15 ppb action level, and describes a study anticipated for completion in summer 2026. Those statements remain attributed to the 2025 report and do not prove current resolution, compliance, absence of an advisory, or household-tap safety.
  • The official City advisories URL redirected to a placeholder described as coming soon on July 30, 2026, so it is excluded as live-status evidence. The profile links the Water Bureau, contact, and 311 paths instead.
  • The linked official Water Bureau, report, contact, 311, provider, and state pages can change after July 30, 2026. Check those paths for current instructions; this profile does not claim that no active notice exists.
  • The table's printed Yes fields are limited to the aligned 2025 rows and do not establish report-wide or current compliance.
  • 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.
