WILLISTOWN HOMEOWNERS ASSOC is one of 3,064 community water systems in Pennsylvania in the 500 or fewer people size category, formerly serving 300 people from surface water.
EPA's federal records list this system as inactive in 1994; the record below is historical.
As of August 1, 2026, its federal record holds 4 entries between 1989 and 1994, all of which EPA lists as closed. Nothing has been added since 1994.
All 4 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 Lead and Copper Rule and inorganic chemicals.
