DUNGENESS BAY PLAT is one of 3,227 community water systems in Washington in the 500 or fewer people size category, serving 461 people from groundwater.

As of August 1, 2026, its federal record holds 23 entries between 1979 and 2025, all of which EPA lists as closed.

The record involves volatile organic chemicals, the Consumer Confidence Rule, and the Total Coliform Rules.
