As of August 1, 2026, EPA's federal records show 1 item for MOKANE 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.

MOKANE PWS is one of 1,412 community water systems in Missouri in the 500 or fewer people size category, serving 208 people from groundwater.
As of August 1, 2026, its federal record holds 35 entries between 2002 and 2025, of which 1 remains open; none are health-based.
Of the 35, 18 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 Total Coliform Rules, the Consumer Confidence Rule, and the Lead and Copper Rule.

Common questions
Is MOKANE PWS required to publish a Consumer Confidence Report?
- Yes. MOKANE 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 MOKANE PWS’s next Consumer Confidence Report due?
- MOKANE PWS’s next Consumer Confidence Report is due by July 1, 2027. The report covers calendar year 2026.
Does MOKANE PWS have any open drinking water violations on record?
- As of August 1, 2026, EPA's federal records show 1 item for MOKANE 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.
