Consumer Confidence Report status
DEERFIELD HUTTERITE COLONY 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 DEERFIELD HUTTERITE COLONY 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.

DEERFIELD HUTTERITE COLONY is one of 1,084 community water systems in Montana in the 500 or fewer people size category, serving 51 people from groundwater.
As of August 1, 2026, its federal record holds 35 entries between 2006 and 2025, of which 1 remains open; none are health-based.
Of the 35, 30 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 Consumer Confidence Rule.
