SPO CO WATER DIST 3 SYS 4 Water System

Consumer Confidence Report status

SPO CO WATER DIST 3 SYS 4 must publish a Consumer Confidence Report — the annual drinking water quality report covering calendar year 2026 — by July 1, 2027.

As of August 1, 2026, EPA's federal records show no open violations for SPO CO WATER DIST 3 SYS 4.

Data sourced from the EPA ECHO database (SDWA bulk download), last refreshed August 1, 2026. This is a record-keeping and public-information tool — it does not replace Washington’s official records. Always confirm current status with Washington before making decisions based on this information.

SPO CO WATER DIST 3 SYS 4 is one of 112 community water systems in Washington in the 3,301 to 10,000 people size category, serving 6,233 people from groundwater.

As of August 1, 2026, its federal record holds 197 entries between 1979 and 2016, all of which EPA lists as closed. Nothing has been added since 2016.

All 197 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, synthetic organic chemicals, and the Radionuclides and Revised Rad Rule.
