FONTANA WATERWORKS SYSTEM 2 SOUTH is one of 333 community water systems in Wisconsin in the 501 to 3,300 people size category, formerly serving 2,000 people from groundwater.

EPA's federal records list this system as inactive in 1995; the record below is historical.

As of August 1, 2026, its federal record holds 2 entries in 1991, all of which EPA lists as closed. Nothing has been added since 1991.

All 2 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.
