BELMONT WATER TREATMENT PLANT is among the 10 largest community water systems in Pennsylvania, formerly serving 320,000 people from surface water.

EPA's federal records list this system as inactive in 1991; the record below is historical.

As of August 1, 2026, its federal record holds 2 entries in 1979, all of which EPA lists as closed. Nothing has been added since 1979.

All 2 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 Radionuclides and Revised Rad Rule.
