System facts

System ID (PWSID): PA5100132
System type: Community Water System
Population served: 45
Service connections: 1
Ownership: public/private mix
Water source: groundwater (wells)

COLONIAL GARDENS GUEST HOME is one of 3,064 community water systems in Pennsylvania in the 500 or fewer people size category, formerly serving 45 people from groundwater.

EPA's federal records list this system as inactive in 2025; the record below is historical.

As of August 1, 2026, its federal record holds 74 entries between 1994 and 2024, all of which EPA lists as closed.

Of the 74, 65 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 synthetic organic chemicals, volatile organic chemicals, and the Stage 1 Disinfectants and Disinfection Byproducts Rule.
