Is SILEX PWS required to publish a Consumer Confidence Report?

Yes. SILEX PWS is a community water system, and federal rules (40 CFR 141 Subpart O) require every community water system to publish a Consumer Confidence Report each year.

When is SILEX PWS’s next Consumer Confidence Report due?

SILEX PWS’s next Consumer Confidence Report is due by July 1, 2027. The report covers calendar year 2026.

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.

SILEX PWS Water System

Consumer Confidence Report status

SILEX 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 SILEX 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): MO6010902
System type: Community Water System
Population served: 206
Service connections: 98
Ownership: local government
Water source: surface water (rivers, lakes, or reservoirs)

SILEX PWS is one of 1,412 community water systems in Missouri in the 500 or fewer people size category, serving 206 people from surface water.

As of August 1, 2026, its federal record holds 92 entries between 1992 and 2025, of which 1 remains open; none are health-based.

Of the 92, 31 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.

Common questions

Is SILEX PWS required to publish a Consumer Confidence Report?: Yes. SILEX PWS is a community water system, and federal rules (40 CFR 141 Subpart O) require every community water system to publish a Consumer Confidence Report each year.
When is SILEX PWS’s next Consumer Confidence Report due?: SILEX PWS’s next Consumer Confidence Report is due by July 1, 2027. The report covers calendar year 2026.
Does SILEX PWS have any open drinking water violations on record?: As of August 1, 2026, EPA's federal records show 1 item for SILEX 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.
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.
