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.

System facts

System ID (PWSID): MT0000400
System type: Community Water System
Population served: 750
Service connections: 300
Ownership: local government
Water source: surface water (rivers, lakes, or reservoirs)

TIBER COUNTY WATER DISTRICT is one of 123 community water systems in Montana in the 501 to 3,300 people size category, serving 750 people from surface water.

As of August 1, 2026, its federal record holds 164 entries between 1993 and 2024, all of which EPA lists as closed.

Of the 164, 143 are monitoring and reporting requirements — the category that accounts for about four in five of all violations in EPA's national dataset — rather than findings about the water itself. The record involves volatile organic chemicals, synthetic organic chemicals, and inorganic chemicals.

Common questions

Is TIBER COUNTY WATER DISTRICT required to publish a Consumer Confidence Report?: Yes. TIBER COUNTY WATER DISTRICT 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 TIBER COUNTY WATER DISTRICT’s next Consumer Confidence Report due?: TIBER COUNTY WATER DISTRICT’s next Consumer Confidence Report is due by July 1, 2027. The report covers calendar year 2026.
Does TIBER COUNTY WATER DISTRICT have any open drinking water violations on record?: As of August 1, 2026, EPA's federal records show no open violations for TIBER COUNTY WATER DISTRICT.
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.
