PANTHER LAKE COMMUNITY WATER SYSTEM is one of 3,227 community water systems in Washington in the 500 or fewer people size category, serving 47 people from groundwater.

As of August 1, 2026, its federal record holds 6 entries between 1992 and 2015, all of which EPA lists as closed. Nothing has been added since 2015.

Of the 6, 4 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 the Total Coliform Rules, the Lead and Copper Rule, and the Consumer Confidence Rule.

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.
