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): NV0000767
System type: Community Water System
Population served: 54
Service connections: 20
Ownership: privately owned
Water source: groundwater (wells)

ROSEMOUNT WATER CO is one of 293 community water systems in Nevada in the 500 or fewer people size category, serving 54 people from groundwater.

As of August 1, 2026, its federal record holds 126 entries between 2012 and 2026, all of which EPA lists as closed.

Of the 126, 88 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 the Radionuclides and Revised Rad Rule, the Public Notice Rule and Revised PN Rule, and the Stage 2 Disinfectants and Disinfection Byproducts Rule.

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