MC PHERSON HILLS WATER SYSTEM is one of 3,227 community water systems in Washington in the 500 or fewer people size category, serving 30 people from groundwater.

As of August 1, 2026, its federal record holds 51 entries between 1979 and 2005, all of which EPA lists as closed. Nothing has been added since 2005.

Of the 51, 46 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.

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.
