LONDON WATER CO-OP is one of 1,168 community water systems in Oregon in the 500 or fewer people size category, serving 63 people from surface water.
As of August 1, 2026, its federal record holds 441 entries between 1976 and 2026, of which 1 health-based item remains open, alongside 7 other open entries.
Of the 441, 317 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, volatile organic chemicals, and the Public Notice Rule and Revised PN Rule.
