MASON CREEK UTILITY DISTRICT is one of 817 community water systems in Texas in the 3,301 to 10,000 people size category, serving 8,900 people from groundwater.

As of August 1, 2026, its federal record holds 12 entries between 1992 and 2016, all of which EPA lists as closed. Nothing has been added since 2016.

Of the 12, 8 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 1 Disinfectants and Disinfection Byproducts Rule, the Public Notice Rule and Revised PN Rule, and the Total Coliform Rules.
