TRI TWP WATER AUTH is one of 757 community water systems in Pennsylvania in the 501 to 3,300 people size category, formerly serving 1,227 people from surface water.

EPA's federal records list this system as inactive in 2023; the record below is historical.

As of August 1, 2026, its federal record holds 39 entries between 1989 and 2020, all of which EPA lists as closed. Nothing has been added since 2020.

Of the 39, 36 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 Surface Water Treatment Rules, the Stage 1 Disinfectants and Disinfection Byproducts Rule, and the Stage 2 Disinfectants and Disinfection Byproducts Rule.
