LODGE GRASS TOWN OF Water System
Consumer Confidence Report status
LODGE GRASS 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 LODGE GRASS 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.

LODGE GRASS TOWN OF is one of 1,084 community water systems in Montana in the 500 or fewer people size category, serving 480 people from groundwater.
As of August 1, 2026, its federal record holds 154 entries between 1992 and 2025, of which 1 remains open; none are health-based.
Of the 154, 150 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 LODGE GRASS TOWN OF required to publish a Consumer Confidence Report?
- Yes. LODGE GRASS 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 LODGE GRASS TOWN OF’s next Consumer Confidence Report due?
- LODGE GRASS TOWN OF’s next Consumer Confidence Report is due by July 1, 2027. The report covers calendar year 2026.
Does LODGE GRASS TOWN OF have any open drinking water violations on record?
- As of August 1, 2026, EPA's federal records show 1 item for LODGE GRASS 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.
