CITY OF LEON VALLEY is one of 817 community water systems in Texas in the 3,301 to 10,000 people size category, serving 7,794 people from groundwater.
As of August 1, 2026, its federal record holds 41 entries between 2004 and 2025, all of which EPA lists as closed.
Of the 41, 39 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 volatile organic chemicals, the Stage 1 Disinfectants and Disinfection Byproducts Rule, and the Lead and Copper Rule.
