LAGUNA MADRE WATER DISTRICT is one of 385 community water systems in Texas in the 10,001 to 100,000 people size category, serving 46,674 people from surface water.

As of August 1, 2026, its federal record holds 31 entries between 1998 and 2025, all of which EPA lists as closed.

The record involves the Stage 1 Disinfectants and Disinfection Byproducts Rule, the Stage 2 Disinfectants and Disinfection Byproducts Rule, and the Public Notice Rule and Revised PN Rule.
