Report context

Three New York systems and their 2025 reports

These source descriptions and dated disclosures come from existing profiles reviewed July 30, 2026. The report year, individual monitoring periods, and later plans remain separate.

New York City · NY7003493

Catskill, Delaware, and Croton supplies

New York City’s 2025 report describes the Catskill, Delaware, and Croton surface-water supplies. The reservoir and watershed locations differ from the city’s customer locations. This report-period description does not identify the source reaching a particular building today.

Buffalo · NY1400422

Lake Erie and dated monitoring disclosures

Buffalo’s 2025 annual report identifies Lake Erie as its source. It also describes missed lead-and-copper reporting or certification deadlines and incomplete sampling during the January–June 2025 monitoring period.

Those disclosures concern the report’s stated periods. They do not establish a household lead result or the system’s current compliance or advisory status.

Rochester · NY2704518

City sources and purchased county-authority water

Rochester’s 2025 report identifies Hemlock Lake and Canadice Lake and describes purchases from Monroe County Water Authority, whose source is Lake Ontario. Rochester City and the county authority remain separate systems.

The report also describes an April 2025 corrosion-control administrative decision and a study anticipated for summer 2026. An expected date in that report is not verification that the study or subsequent work has been completed.

Statewide context

Separate service identity from source location

Public-system identity

A city name can point to several different records

The selected public water system IDs are NY7003493 for New York City, NY1400422 for Buffalo, and NY2704518 for Rochester City. Use the PWSID alongside the supplier’s name when matching an official report.

An office address, reservoir location, county, or city entry point does not establish service to your building. Confirm the supplier from a bill, landlord, or provider before applying a report to your household.

The state portal distinguishes Department of Health and local health department oversight of public drinking water from Department of Environmental Conservation information about rivers, lakes, and other water resources. Choose the view relevant to your question.

Purchased water

Keep the receiving system and supplying utility separate

Rochester’s report describes both city water sources and purchased Monroe County Water Authority water. That relationship provides system-level source context; it does not merge the providers or assign a source mix to a particular address.

Source assessments

A source-water assessment is different from a tap test

Buffalo’s report explains that a source-water assessment considers potential threats to an untreated source. It distinguishes that assessment from the quality of treated, finished water. Use the assessment for source context and the correct sample record for a result; neither alone determines conditions at a particular tap.

Official lookup

Match the system before selecting its records

Official system identity

Compare the name and full PWSID

Know Your NY Water separates Drinking Water Reports from the NY Waters Map. Its homepage accepts an address, city, county, or ZIP code. Use geographic search to orient your browsing; an entered place or address does not establish the provider serving a property.

EPA’s exact identity record for NY7003493 names NEW YORK CITY SYSTEM. Compare that identity with the PWSID printed in New York City’s official annual report. Use the matching public system, rather than a similarly named place or source facility.

  1. Find the supplier and PWSID on your bill or annual report.
  2. Compare the name and full identifier with the official record; retain the NY prefix.
  3. Read the record’s reporting period and scope, and contact the supplier or health department if the identity is unclear.

Report selection

Use the correct system and reporting period

New York City, Buffalo, and Rochester publish separate annual reports covering 2025. Individual samples, administrative events, and notices inside them can carry different dates. A later publication or plan does not make all underlying information current.

If the report is missing or difficult to use, request the correct system’s report from the provider. Ask for an accessible copy or language assistance when needed.

Official guidance

Use the appropriate path for a notice or household question

Provider instructions

Distinguish water-quality notices from service messages

A boil-water instruction, a lead-service-line material letter, and a billing or service-shutoff message have different purposes. Buffalo’s July 30, 2026 source review recorded an undated service-shutoff banner; that was billing and service context, not a drinking-water advisory.

For current instructions, confirm your provider and affected area and read the latest notice directly. Ask the provider or health department when its date, scope, or status is unclear; a historical report or missing entry does not establish today’s conditions.

Service-line materials

Use the inventory and the right notification letter

Get Water Wise Buffalo links the provider’s service-line inventory map and a material-reporting survey. It also lists separate 2024 notification letters for known lead, galvanized requiring replacement, and unknown service-line materials.

An unknown material is a reason to ask the provider for clarification. A material inventory, a notification letter, a monitoring-completeness disclosure, and a household water test are different kinds of information.

Monitoring and reporting

Read a missing-data disclosure for what it establishes

Buffalo’s 2025 report distinguishes required sample submission and certification obligations from the contaminant results themselves. Rochester’s report separately explains its dated corrosion-control administrative history.

Missing monitoring data are not a zero result. A report-period administrative disclosure does not establish current resolution or conditions at your tap; read the full provider explanation and check for later official updates.

Private wells

Follow New York’s private-well testing guidance

NYSDOH recommends testing private-well water for bacteria at least annually and for other contaminants every three to five years. Its guidance also describes retesting after maintenance, disinfection, and floods. The selected city-system reports do not test your individual well.

Ask your local health department about the tests for your circumstances, and use the state’s certified-laboratory directory to find testing services. A risk map, nearby lake, or public-system result does not replace laboratory testing of your well.

Common questions

Reading New York water information

Does a reservoir’s location identify the utility serving me?

No. Source reservoirs can be outside the customer’s municipality. Match your bill or provider-confirmed supplier with the public water system ID; a source location does not prove service to your building.

Are Rochester City and Monroe County Water Authority the same system?

No. Rochester’s report describes purchased county-authority water alongside its city sources, but the regulatory systems remain distinct. Use the report for your confirmed supplier and keep the source relationship separate from address-level service.

Does a 2025 report contain only events from 2025?

Not necessarily. The selected reports preserve earlier sample or administrative dates and later plans. Rochester’s report, for example, anticipated a study for summer 2026; that statement is not evidence that it has since been completed.

Does an unknown service line mean a lead test found lead?

No. Unknown describes missing or unconfirmed material information in an inventory. Ask the provider how to clarify the material and obtain the appropriate testing guidance; the classification is not a household sample result.
