MOUND VALLEY WATER SYSTEM is one of 969 community water systems in Idaho in the 500 or fewer people size category, formerly serving 30 people from surface water.
EPA's federal records list this system as inactive in 1992; the record below is historical.
As of August 1, 2026, its federal record holds 6 entries in 1979, all of which EPA lists as closed. Nothing has been added since 1979.
All 6 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 synthetic organic chemicals.
