PATTERSON MHP is one of 1,572 community water systems in Illinois in the 500 or fewer people size category, formerly serving 24 people from groundwater.

EPA's federal records list this system as inactive in 2009; the record below is historical.

As of August 1, 2026, its federal record holds 10 entries between 1993 and 2004, all of which EPA lists as closed. Nothing has been added since 2004.
