ARGYLE ESTATES WATER SUPPLY is one of 1,412 community water systems in Missouri in the 500 or fewer people size category, serving 380 people from groundwater.
As of August 1, 2026, its federal record holds 29 entries between 1992 and 2025, of which 3 remain open; none are health-based.
Of the 29, 12 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 Total Coliform Rules, the Consumer Confidence Rule, and the Public Notice Rule and Revised PN Rule.
