PSW-IVY HILL is one of 3,064 community water systems in Pennsylvania in the 500 or fewer people size category, formerly serving 50 people from groundwater.
EPA's federal records list this system as inactive in 1995; the record below is historical.
As of August 1, 2026, its federal record holds 10 entries between 1985 and 1993, all of which EPA lists as closed. Nothing has been added since 1993.
All 10 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 inorganic chemicals and the Total Coliform Rules.
