AHEARN WATER SYSTEM is one of 3,227 community water systems in Washington in the 500 or fewer people size category, serving 91 people from groundwater.

As of August 1, 2026, its federal record holds 38 entries between 1995 and 2013, all of which EPA lists as closed. Nothing has been added since 2013.

Of the 38, 36 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, inorganic chemicals, and the Lead and Copper Rule.

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