FLATHEAD CO WATER DISTRICT NO 8 Water System
Consumer Confidence Report status
FLATHEAD CO WATER DISTRICT NO 8 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 FLATHEAD CO WATER DISTRICT NO 8.
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.

FLATHEAD CO WATER DISTRICT NO 8 is one of 1,084 community water systems in Montana in the 500 or fewer people size category, serving 475 people from groundwater.
As of August 1, 2026, its federal record holds 170 entries between 1993 and 2013, all of which EPA lists as closed. Nothing has been added since 2013.
Of the 170, 165 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 synthetic organic chemicals, volatile organic chemicals, and the Radionuclides and Revised Rad Rule.

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.
