STEPTOE WATER/SEWER DISTRICT Water System

Consumer Confidence Report status

STEPTOE WATER/SEWER DISTRICT 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 STEPTOE WATER/SEWER DISTRICT.

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.

STEPTOE WATER/SEWER DISTRICT is one of 3,227 community water systems in Washington in the 500 or fewer people size category, serving 210 people from groundwater.

As of August 1, 2026, its federal record holds 103 entries between 1993 and 2023, all of which EPA lists as closed. Nothing has been added since 2023.

Of the 103, 100 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 Total Coliform Rules.

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