RIVERSIDE TOWN OF Water System

Consumer Confidence Report status

RIVERSIDE TOWN OF 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 2 items for RIVERSIDE TOWN OF that are open and awaiting resolution. None are health-based violations — open items of this kind are most often monitoring or reporting requirements, not water-safety findings.

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.

RIVERSIDE TOWN OF is one of 3,227 community water systems in Washington in the 500 or fewer people size category, serving 429 people from groundwater.

As of August 1, 2026, its federal record holds 112 entries between 1979 and 2025, of which 2 remain open; none are health-based.

Of the 112, 108 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 inorganic chemicals.
