NORTHWEST HILLS WATER SUPPLY is one of 4,188 community water systems in Texas in the 500 or fewer people size category, serving 219 people from groundwater.

As of August 1, 2026, its federal record holds 8 entries between 1999 and 2015, all of which EPA lists as closed. Nothing has been added since 2015.

Of the 8, 5 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 Radionuclides and Revised Rad Rule, the Lead and Copper Rule, and the Public Notice Rule and Revised PN Rule.
