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.

BONNE TERRE PWS Water System

Consumer Confidence Report status

BONNE TERRE PWS 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 BONNE TERRE PWS 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 Missouri’s official records. Always confirm current status with Missouri before making decisions based on this information.

System facts

System ID (PWSID): MO4010087
System type: Community Water System
Population served: 3,537
Service connections: 1,597
Ownership: local government
Water source: groundwater (wells)

BONNE TERRE PWS is one of 140 community water systems in Missouri in the 3,301 to 10,000 people size category, serving 3,537 people from groundwater.

As of August 1, 2026, its federal record holds 108 entries between 1981 and 2025, of which 1 remains open; none are health-based.

Of the 108, 10 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 the Radionuclides and Revised Rad Rule, the Total Coliform Rules, and the Public Notice Rule and Revised PN Rule.

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.
