BOSTON HARBOR is one of 428 community water systems in Washington in the 501 to 3,300 people size category, serving 1,153 people from groundwater.

As of August 1, 2026, its federal record holds 38 entries between 1979 and 2025, all of which EPA lists as closed.

Of the 38, 32 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 volatile organic chemicals, the Total Coliform Rules, and inorganic chemicals.

What is a Consumer Confidence Report?

EPA’s revised CCR rule takes effect January 1, 2027, and the first reports in the new format are due July 1, 2027.
