MAMMOTH WATER USERS is one of 338 community water systems in Utah in the 500 or fewer people size category, formerly serving 60 people from surface water.
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 15 entries in 1983, all of which EPA lists as closed. Nothing has been added since 1983.
All 15 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, synthetic organic chemicals, and the Radionuclides and Revised Rad Rule.
