System facts

System ID (PWSID): IL1635185
System type: Community Water System
Population served: 40
Service connections: 21
Ownership: privately owned
Water source: groundwater (wells)

SPRING VALLEY MHP is one of 1,572 community water systems in Illinois in the 500 or fewer people size category, formerly serving 40 people from groundwater.

EPA's federal records list this system as inactive in 1994; the record below is historical.

As of August 1, 2026, its federal record holds 50 entries between 1992 and 1994, all of which EPA lists as closed. Nothing has been added since 1994.

Of the 50, 49 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, the Total Coliform Rules, and the Lead and Copper Rule.
