STEVENS CO PUD - CHATTAROY SPRING W is one of 3,227 community water systems in Washington in the 500 or fewer people size category, formerly serving 138 people from groundwater.

EPA's federal records list this system as inactive in 2013; the record below is historical.

As of August 1, 2026, its federal record holds 59 entries between 1979 and 2007, all of which EPA lists as closed. Nothing has been added since 2007.

All 59 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 synthetic organic chemicals, volatile organic chemicals, and inorganic chemicals.
