HARTSHORNE is one of 511 community water systems in Oklahoma in the 501 to 3,300 people size category, serving 2,300 people from surface water.

As of August 1, 2026, its federal record holds 49 entries between 1995 and 2024, all of which EPA lists as closed.

Of the 49, 20 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 Stage 2 Disinfectants and Disinfection Byproducts Rule, the Total Coliform Rules, and the Lead and Copper Rule.
