ROCKY LAKE WATER CO is one of 272 community water systems in Arizona in the 501 to 3,300 people size category, formerly serving 1,328 people from groundwater.

EPA's federal records list this system as inactive in 2004; the record below is historical.

As of August 1, 2026, its federal record holds 26 entries between 1979 and 1990, all of which EPA lists as closed. Nothing has been added since 1990.

Of the 26, 23 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.
