FOREST GROVE TRANSMISSION LINE is one of 1,168 community water systems in Oregon in the 500 or fewer people size category, formerly serving 300 people from surface water.

EPA's federal records list this system as inactive in 1995; the record below is historical.

As of August 1, 2026, its federal record holds 19 entries between 1992 and 1995, all of which EPA lists as closed. Nothing has been added since 1995.

Of the 19, 11 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 Total Coliform Rules, and the Lead and Copper Rule.
