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.

Consumer Confidence Report status

FOSS 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 FOSS 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 Oklahoma’s official records. Always confirm current status with Oklahoma before making decisions based on this information.

System facts

System ID (PWSID): OK2007508
System type: Community Water System
Population served: 127
Service connections: 90
Ownership: local government
Water source: surface water (rivers, lakes, or reservoirs)

FOSS is one of 1,277 community water systems in Oklahoma in the 500 or fewer people size category, serving 127 people from surface water.

As of August 1, 2026, its federal record holds 66 entries between 2008 and 2025, of which 1 remains open; none are health-based.

Of the 66, 64 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, the Stage 1 Disinfectants and Disinfection Byproducts Rule, and the Lead and Copper Rule.
