What is a Consumer Confidence Report?

A Consumer Confidence Report (CCR) is the annual drinking water quality report that community water systems must provide to the people they serve. It lists the contaminants detected in the system’s water during the year, where the water comes from, and how the results compare with federal limits. EPA’s revised CCR rule takes effect January 1, 2027, and the first reports in the new format are due July 1, 2027.

TWIN PINES MOBILE HOME PARK Water System

Consumer Confidence Report status

TWIN PINES MOBILE HOME PARK 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 1 item for TWIN PINES MOBILE HOME PARK that is 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.

System facts

System ID (PWSID): WA5331790
System type: Community Water System
Population served: 25
Service connections: 14
Ownership: privately owned
Water source: groundwater (wells)

TWIN PINES MOBILE HOME PARK is one of 3,227 community water systems in Washington in the 500 or fewer people size category, serving 25 people from groundwater.

As of August 1, 2026, its federal record holds 274 entries between 2019 and 2026, of which 1 remains open; none are health-based.

All 274 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.

What is a Consumer Confidence Report?: A Consumer Confidence Report (CCR) is the annual drinking water quality report that community water systems must provide to the people they serve. It lists the contaminants detected in the system’s water during the year, where the water comes from, and how the results compare with federal limits. EPA’s revised CCR rule takes effect January 1, 2027, and the first reports in the new format are due July 1, 2027.
