SOUTHEAST TACOMA MUTUAL WATER CO is one of 111 community water systems in Washington in the 10,001 to 100,000 people size category, formerly serving 10,850 people from groundwater.
EPA's federal records list this system as inactive in 2001; the record below is historical.
As of August 1, 2026, its federal record holds 8 entries between 1979 and 1996, all of which EPA lists as closed. Nothing has been added since 1996.
Of the 8, 7 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 inorganic chemicals, the Total Coliform Rules, and the Radionuclides and Revised Rad Rule.
