SANTA FE MNP is one of 1,572 community water systems in Illinois in the 500 or fewer people size category, formerly serving 88 people from groundwater.

EPA's federal records list this system as inactive in 1999; the record below is historical.

As of August 1, 2026, its federal record holds 18 entries between 1992 and 1993, all of which EPA lists as closed. Nothing has been added since 1993.

All 18 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 the Total Coliform Rules, volatile organic chemicals, and the Lead and Copper Rule.
