ST BARNABAS NURSING HOME is one of 3,064 community water systems in Pennsylvania in the 500 or fewer people size category, formerly serving 275 people from surface water.
EPA's federal records list this system as inactive in 2000; the record below is historical.
As of August 1, 2026, its federal record holds 26 entries between 1985 and 1995, all of which EPA lists as closed. Nothing has been added since 1995.
All 26 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 volatile organic chemicals.
