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.

HILDRETH SUBDIVISION NO 3 Water System

Consumer Confidence Report status

HILDRETH SUBDIVISION NO 3 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 no open violations for HILDRETH SUBDIVISION NO 3.

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): MT0003968
System type: Community Water System
Population served: 128
Service connections: 42
Ownership: privately owned
Water source: groundwater (wells)

HILDRETH SUBDIVISION NO 3 is one of 1,084 community water systems in Montana in the 500 or fewer people size category, serving 128 people from groundwater.

As of August 1, 2026, its federal record holds 62 entries between 1996 and 2024, all of which EPA lists as closed.

Of the 62, 54 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 the Total Coliform Rules.
