PARK CREST WTR CMPNY is one of 773 community water systems in Illinois in the 501 to 3,300 people size category, formerly serving 1,100 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 43 entries between 1977 and 1995, all of which EPA lists as closed. Nothing has been added since 1995.

Of the 43, 41 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, synthetic organic chemicals, and the Total Coliform Rules.
