SLEIGHTON SCHOOL is one of 3,064 community water systems in Pennsylvania in the 500 or fewer people size category, formerly serving 300 people from groundwater.
EPA's federal records list this system as inactive in 2002; the record below is historical.
As of August 1, 2026, its federal record holds 14 entries between 1982 and 1993, all of which EPA lists as closed. Nothing has been added since 1993.
All 14 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 synthetic organic chemicals.
