MOUNT VERNON WATER WORKS is one of 128 community water systems in Indiana in the 3,301 to 10,000 people size category, serving 6,426 people from surface water.

As of August 1, 2026, its federal record holds 11 entries between 1979 and 2015, all of which EPA lists as closed. Nothing has been added since 2015.

All 11 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 and synthetic organic chemicals.
