What is a Consumer Confidence Report?

A Consumer Confidence Report (CCR) is the annual drinking water quality report that community water systems must provide to the people they serve. It lists the contaminants detected in the system’s water during the year, where the water comes from, and how the results compare with federal limits. EPA’s revised CCR rule takes effect January 1, 2027, and the first reports in the new format are due July 1, 2027.

WINIFRED TOWN OF Water System

Consumer Confidence Report status

WINIFRED TOWN OF must publish a Consumer Confidence Report — the annual drinking water quality report covering calendar year 2026 — by July 1, 2027.

As of August 1, 2026, EPA's federal records show 1 item for WINIFRED TOWN OF that is open and awaiting resolution. None are health-based violations — open items of this kind are most often monitoring or reporting requirements, not water-safety findings.

Data sourced from the EPA ECHO database (SDWA bulk download), last refreshed August 1, 2026. This is a record-keeping and public-information tool — it does not replace Montana’s official records. Always confirm current status with Montana before making decisions based on this information.

System facts

System ID (PWSID): MT0000363
System type: Community Water System
Population served: 274
Service connections: 121
Ownership: local government
Water source: groundwater (wells)

Common questions

Is WINIFRED TOWN OF required to publish a Consumer Confidence Report?: Yes. WINIFRED TOWN OF is a community water system, and federal rules (40 CFR 141 Subpart O) require every community water system to publish a Consumer Confidence Report each year.
When is WINIFRED TOWN OF’s next Consumer Confidence Report due?: WINIFRED TOWN OF’s next Consumer Confidence Report is due by July 1, 2027. The report covers calendar year 2026.
Does WINIFRED TOWN OF have any open drinking water violations on record?: As of August 1, 2026, EPA's federal records show 1 item for WINIFRED TOWN OF that is open and awaiting resolution. None are health-based violations — open items of this kind are most often monitoring or reporting requirements, not water-safety findings.
What is a Consumer Confidence Report?: A Consumer Confidence Report (CCR) is the annual drinking water quality report that community water systems must provide to the people they serve. It lists the contaminants detected in the system’s water during the year, where the water comes from, and how the results compare with federal limits. EPA’s revised CCR rule takes effect January 1, 2027, and the first reports in the new format are due July 1, 2027.
