PIONEER WATER COMPANY is one of 3,227 community water systems in Washington in the 500 or fewer people size category, serving 443 people from groundwater.

As of August 1, 2026, its federal record holds 43 entries between 2005 and 2026, all of which EPA lists as closed.

Of the 43, 38 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 Consumer Confidence Rule.

EPA’s revised CCR rule takes effect January 1, 2027, and the first reports in the new format are due July 1, 2027.
