BERNEIL WATER COMPANY is one of 272 community water systems in Arizona in the 501 to 3,300 people size category, serving 1,388 people from groundwater.
As of August 1, 2026, its federal record holds 16 entries between 1988 and 2023, all of which EPA lists as closed. Nothing has been added since 2023.

The record involves inorganic chemicals, the Stage 1 Disinfectants and Disinfection Byproducts Rule, and the Total Coliform Rules.
