TRI-CITY WATER DISTRICT #45 is one of 3,227 community water systems in Washington in the 500 or fewer people size category, serving 300 people from groundwater.

As of August 1, 2026, its federal record holds 75 entries between 1979 and 2008, all of which EPA lists as closed. Nothing has been added since 2008.

All 75 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 Total Coliform Rules.

When is TRI-CITY WATER DISTRICT #45’s next Consumer Confidence Report due?

TRI-CITY WATER DISTRICT #45’s next Consumer Confidence Report is due by July 1, 2027. The report covers calendar year 2026.

What is a Consumer Confidence Report?

A Consumer Confidence Report (CCR) is the annual drinking water quality report that community water systems must provide to the people they serve. It lists the contaminants detected in the system’s water during the year, where the water comes from, and how the results compare with federal limits. EPA’s revised CCR rule takes effect January 1, 2027, and the first reports in the new format are due July 1, 2027.
