Still in violation

EPA data updated Oct 7, 2026

Ground Water Rule

Monitoring and Reporting

1 violation, Jun 2026 to open · E. coli (Escherichia coli)
EPA rule code 140 · 1 violation recorded, 1 still open

Monitoring and Reporting: 1 violation, open since Jun 2026. The system did not complete required monitoring, or did not report the results on time. This does not show that a contaminant was found.

Contaminant on the record: E. coli (Escherichia coli).

Public Notice Rule and Revised PN Rule

Other Violation

2 violations, Apr 2006 to open · Public Notification Rule
EPA rule code 410 · 2 violations recorded, 2 still open

Other Violation: 2 violations, open since Apr 2006. A requirement other than monitoring, reporting, or a contaminant limit, such as public notice or the annual water quality report.

Contaminant on the record: Public Notification Rule.

Also violated in the past three years

Jul to Sep 2023 to Jul to Sep 2026

Revised Total Coliform Rule

Monitoring ViolationTreatment Technique Violation Health-based

5 violations, Sep 2025 to Jun 2026
EPA rule code 111 · 5 violations recorded, 1 health-based

Treatment Technique Violation, health-based: 1 violation, Sep 2025 to Oct 2025. The system did not carry out a required treatment process or corrective action.

Monitoring Violation: 4 violations, Sep 2025 to Jun 2026. The system did not complete required monitoring. This does not show that a contaminant was found.

What the rule requires: The 2013 RTCR (effective 2016) replaced the original TCR. It triggers automatic E. coli testing whenever total coliform is found. A single E. coli-positive sample is an acute MCL violation. It also requires systems exceeding 5% total coliform-positive samples to conduct a formal assessment and correct any deficiencies, helping prevent contamination before it escalates.

Health effects: Total coliform bacteria indicate that the disinfection barrier has been breached or fecal contamination is entering the system. E. coli specifically indicates fecal contamination and the possible presence of disease-causing pathogens (norovirus, Salmonella, Shigella, Campylobacter). Illness can be severe in elderly, young children, and immunocompromised individuals. Limit: Zero E. coli; ≤5% of monthly samples total coliform-positive

About this rule
About this data

Rules violated and the list above come from EPA's SDWIS violation records, one row per violation and contaminant, grouped by the rule each row belongs to. A violation counts when its non-compliance period ended on or after Jul 1, 2023, the start of the thirteen quarters ECHO's three-year figures cover, or is still open; it is unresolved when it was still open at EPA's data refresh on Oct 7, 2026. EPA's rule code 500, "Not Regulated", is left out, as in ECHO's counts. Each rule's violation count is EPA's, and one rule can carry several: a missed monitoring round for a group of contaminants is one violation per contaminant and period. Category names are EPA's violation categories.

ECHO's own summary count of rules violated agrees with this grouping for 98.8% of active systems nationally, and its count of rules being violated for 98.7%; where they differ, the figures here follow the rows listed.

Measured contaminant levels are not part of this record; each system publishes them in its annual Consumer Confidence Report.

Service area from EPA's Public Water System Service Area Boundaries dataset: location confidence HIGHER. The system's location is the centre of the service area EPA publishes for the system.

The Missouri records are from EPA's data refresh of Oct 7, 2026; EPA refreshes this data quarterly, and states report to EPA with a lag of three to six months, so the newest violations may not appear yet.
