LAKE WHATCOM RESIDENTIAL TREAT.CTR is one of 3,227 community water systems in Washington in the 500 or fewer people size category, formerly serving 94 people from groundwater.
EPA's federal records list this system as inactive in 2008; the record below is historical.
As of August 1, 2026, its federal record holds 6 entries between 1992 and 2000, all of which EPA lists as closed. Nothing has been added since 2000.
All 6 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 Total Coliform Rules.
