TANKERSLEY WATER CO/CLAX is one of 272 community water systems in Arizona in the 501 to 3,300 people size category, formerly serving 525 people from groundwater.

EPA's federal records list this system as inactive in 1997; the record below is historical.

As of August 1, 2026, its federal record holds 17 entries between 1982 and 1990, all of which EPA lists as closed. Nothing has been added since 1990.

All 17 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 inorganic chemicals, volatile organic chemicals, and the Radionuclides and Revised Rad Rule.
