AMARILLO MUTUAL WATER COMPANY is one of 728 community water systems in California in the 501 to 3,300 people size category, serving 3,134 people from groundwater.
As of August 1, 2026, its federal record holds 9 entries between 1999 and 2022, all of which EPA lists as closed. Nothing has been added since 2022.
All 9 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 and the Total Coliform Rules.
