SOMERSET CNTY QUEMAHONING SYST is one of 3,064 community water systems in Pennsylvania in the 500 or fewer people size category, serving 25 people from surface water.

As of August 1, 2026, its federal record holds 33 entries between 2010 and 2025, all of which EPA lists as closed.

Of the 33, 29 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, the Stage 1 Disinfectants and Disinfection Byproducts Rule, and the Surface Water Treatment Rules.
