RIDGE ON THE COMMONS is one of 3,064 community water systems in Pennsylvania in the 500 or fewer people size category, serving 30 people from groundwater.
As of August 1, 2026, its federal record holds 35 entries between 2009 and 2025, all of which EPA lists as closed.
All 35 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 Radionuclides and Revised Rad Rule, volatile organic chemicals, and synthetic organic chemicals.
