KNOXVILLE WATER DEPARTMENT is one of 757 community water systems in Pennsylvania in the 501 to 3,300 people size category, serving 590 people from groundwater.
As of August 1, 2026, its federal record holds 237 entries between 1995 and 2025, all of which EPA lists as closed.
Of the 237, 205 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 Groundwater Rule.
