SHELTON CITY OF is one of 111 community water systems in Washington in the 10,001 to 100,000 people size category, serving 15,089 people from groundwater.

As of August 1, 2026, its federal record holds 27 entries between 1979 and 2017, all of which EPA lists as closed. Nothing has been added since 2017.

Of the 27, 23 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 the Consumer Confidence Rule.
