ISLAND LAKE WTR CMPNY is one of 1,572 community water systems in Illinois in the 500 or fewer people size category, formerly serving 25 people from groundwater.
EPA's federal records list this system as inactive in 1996; the record below is historical.
As of August 1, 2026, its federal record holds 7 entries between 1977 and 1993, all of which EPA lists as closed. Nothing has been added since 1993.
