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.

LEADWOOD PWS Water System

Consumer Confidence Report status

LEADWOOD 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 LEADWOOD 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): MO4010456
System type: Community Water System
Population served: 1,200
Service connections: 437
Ownership: local government
Water source: groundwater (wells)

LEADWOOD PWS is one of 489 community water systems in Missouri in the 501 to 3,300 people size category, serving 1,200 people from groundwater.

As of August 1, 2026, its federal record holds 72 entries between 1993 and 2026, of which 1 remains open; none are health-based.

Of the 72, 22 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 Groundwater Rule, and the Lead and Copper Rule.
