TRENTWOOD IRRIGATION DISTRICT 3 is one of 112 community water systems in Washington in the 3,301 to 10,000 people size category, serving 4,228 people from groundwater.

As of August 1, 2026, its federal record holds 36 entries between 1979 and 2025, all of which EPA lists as closed.

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