HELMET PEAK WATER RES ASN is one of 1,189 community water systems in Arizona in the 500 or fewer people size category, formerly serving 250 people from groundwater.

EPA's federal records list this system as inactive in 1995; the record below is historical.

As of August 1, 2026, its federal record holds 29 entries between 1986 and 1991, all of which EPA lists as closed. Nothing has been added since 1991.

All 29 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.
