Public Notice Rule and Revised PN Rule
Other Violation10 violations, May 2023 to open · Public Notification Rule
Other Violation: 10 violations, 3 still open, May 2023 to open. 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.

Revised Total Coliform Rule
Monitoring Violation1 violation, Oct 2023 to Nov 2023
Monitoring Violation: 1 violation, Oct 2023 to Nov 2023. 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.

Treatment Technique Violation, health-based: 11 violations, Jan 2024 to May 2025. The system did not carry out a required treatment process or corrective action.
Monitoring and Reporting: 6 violations, Jan 2024 to 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.
Other Violation: 1 violation, Dec 2024 to Mar 2025. A requirement other than monitoring, reporting, or a contaminant limit, such as public notice or the annual water quality report.
Contaminant on the record: Interim Enhanced Surface Water Treatment Rule.
Interim Enhanced Surface Water Treatment Rule, health effects: Violations indicate failure to meet treatment technique requirements that reduce exposure to Cryptosporidium, Giardia, and other microbial pathogens. Cryptosporidium poses the greatest risk to immunocompromised individuals, infants, and the elderly, and can cause severe or fatal illness in vulnerable populations. Limit: Treatment technique — no numeric MCL; compliance means meeting turbidity limits (0.3 NTU in 95% of monthly samples) and Cryptosporidium removal benchmarks

5 violations, Nov 2022 to Oct 2024
Long Term 2 Enhanced Surface Water Treatment Rule
Monitoring and ReportingTreatment Technique Violation Health-based5 violations, Nov 2022 to Oct 2024
Treatment Technique Violation, health-based: 4 violations, Nov 2022 to Oct 2024. The system did not carry out a required treatment process or corrective action.
Monitoring and Reporting: 1 violation, Dec 2023 to Feb 2024. The system did not complete required monitoring, or did not report the results on time. This does not show that a contaminant was found.
What the rule requires: The LT2 ESWTR (2006) required all surface water and GWUDI systems to monitor source water for Cryptosporidium, then apply additional treatment based on measured concentrations. Higher-bin systems (more oocysts detected) must install advanced treatment — UV disinfection, ozone, or membrane filtration — beyond the original SWTR requirements.
Health effects: Cryptosporidium is a chlorine-resistant protozoan parasite that causes cryptosporidiosis — severe watery diarrhea, cramping, nausea, and fever. In immunocompromised individuals (HIV/AIDS, transplant recipients), it can be life-threatening and prolonged. Infants and the elderly are also at elevated risk. LT2 violations indicate failure to complete monitoring or apply the required additional treatment tier. Limit: Treatment technique — additional Cryptosporidium treatment based on bin classification

24 violations, Sep 2023 to Jun 2026
Surface Water Treatment Rule
Monitoring and ReportingTreatment Technique Violation Health-based24 violations, Sep 2023 to Jun 2026
Treatment Technique Violation, health-based: 1 violation, Jul 2024 to Jul 2024. The system did not carry out a required treatment process or corrective action.
Monitoring and Reporting: 23 violations, Sep 2023 to 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.
What the rule requires: All systems using surface water (rivers, lakes, reservoirs) or groundwater under surface influence (GWUDI) must filter and disinfect. Treatment technique violations mean the system failed to maintain adequate disinfectant residual, exceeded turbidity limits, or lacked required permits. Snowmelt and storm events can raise turbidity and pathogen loads in surface water.
Health effects: Without proper filtration/disinfection: Giardia lamblia (severe diarrhea, cramping), Cryptosporidium (life-threatening for immunocompromised individuals), viruses (hepatitis A, norovirus). Turbidity itself is not a health risk but can shield pathogens from disinfection. Limit: Treatment technique: turbidity ≤0.3 NTU in 95% of monthly samples; detectable disinfectant residual in 95% of distribution samples

Other Violation: 2 violations, Jul 2023 to Jul 2024. A requirement other than monitoring, reporting, or a contaminant limit, such as public notice or the annual water quality report.
What the rule requires: Community water systems must deliver an annual water quality report (Consumer Confidence Report) to all customers by July 1, covering the previous year. It must list all detected contaminants, compare them to MCLs, identify source water, and include educational language about lead. A violation means the report was not delivered on time or was incomplete.

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.
A measured value shown with a rule is the sample result EPA recorded with that violation (SDWIS viol_measure), against the limit EPA recorded on the same row (state_mcl), both in EPA's unit as written; violations without a recorded value, such as missed monitoring, show none. Other measured contaminant levels are not part of this record; each system publishes them in its annual Consumer Confidence Report.
Lead and copper are the newest 90th-percentile results in EPA's SDWA data download (LCR_SAMPLES, codes PB90 and CU90), retrieved on Oct 12, 2026: for each monitoring period a system reports the 90th-percentile value of its tap samples, which EPA compares with its action level of 0.015 mg/L for lead and 1.3 mg/L for copper (40 CFR 141.80). A result is not a measurement of any one tap.

The Kansas 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.
