GLEN MILLS SCHOOL is one of 757 community water systems in Pennsylvania in the 501 to 3,300 people size category, formerly serving 775 people from groundwater.
EPA's federal records list this system as inactive in 1997; the record below is historical.
As of August 1, 2026, its federal record holds 21 entries between 1976 and 1994, all of which EPA lists as closed. Nothing has been added since 1994.
All 21 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 and the Radionuclides and Revised Rad Rule.
