GRONINGER FARMS ARCH ROCK is one of 3,064 community water systems in Pennsylvania in the 500 or fewer people size category, serving 175 people from groundwater.
As of August 1, 2026, its federal record holds 39 entries between 2010 and 2022, all of which EPA lists as closed. Nothing has been added since 2022.
Of the 39, 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 synthetic organic chemicals, the Stage 1 Disinfectants and Disinfection Byproducts Rule, and volatile organic chemicals.
