USFS-ASNF-CHEVELON RANGE is one of 1,189 community water systems in Arizona in the 500 or fewer people size category, formerly serving 200 people from groundwater.
EPA's federal records list this system as inactive in 1998; the record below is historical.
As of August 1, 2026, its federal record holds 20 entries between 1987 and 1988, all of which EPA lists as closed. Nothing has been added since 1988.
All 20 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, inorganic chemicals, and the Radionuclides and Revised Rad Rule.
