AADC (MAPLE HILLS WATER CORPORATION) is one of 1,221 community water systems in Iowa in the 500 or fewer people size category, formerly serving 260 people from groundwater.

EPA's federal records list this system as inactive in 2002; the record below is historical.

As of August 1, 2026, its federal record holds 5 entries between 1989 and 1992, all of which EPA lists as closed. Nothing has been added since 1992.
