RALSTON is one of 1,277 community water systems in Oklahoma in the 500 or fewer people size category, serving 335 people from groundwater.
As of August 1, 2026, its federal record holds 68 entries between 1995 and 2025, all of which EPA lists as closed.
Of the 68, 57 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, the Total Coliform Rules, and the Stage 1 Disinfectants and Disinfection Byproducts Rule.
