GRAYHAWK WATER is one of 489 community water systems in Missouri in the 501 to 3,300 people size category, serving 750 people from groundwater.
As of August 1, 2026, its federal record holds 3 entries between 1995 and 2024, all of which EPA lists as closed.
All 3 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 and the Lead and Copper Rule.
