Revised Total Coliform Rule

Monitoring ViolationOther Violation

3 violations, Jul 2024 to open
EPA rule code 111 · 3 violations recorded, 1 still open

Other Violation: 1 violation, open since Oct 2024. A requirement other than monitoring, reporting, or a contaminant limit, such as public notice or the annual water quality report.

Monitoring Violation: 2 violations, Jul 2024 to Nov 2024. 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.

About this rule

Lead and Copper Rule

Monitoring and Reporting

1 violation, Jan 2025 to open
EPA rule code 350 · 1 violation recorded, 1 still open

Monitoring and Reporting: 1 violation, open since Jan 2025. 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 1991 LCR uses action levels rather than MCLs: if the 90th percentile of high-risk tap samples exceeds 15 ppb lead or 1.3 mg/L copper, the system must take escalating corrective actions. Violations typically indicate failure to maintain adequate corrosion control — the treatment that keeps lead from leaching out of pipes, solder, and fixtures.

Stage 1 Disinfectants and Disinfection Byproducts Rule

Treatment Technique Violation Health-based

1 violation, Sep 2024 to Nov 2024 · Stage 1 Disinfectants and DBP Rule
EPA rule code 210 · 1 violation recorded, 1 health-based

Treatment Technique Violation, health-based: 1 violation, Sep 2024 to Nov 2024. The system did not carry out a required treatment process or corrective action.

Contaminant on the record: Stage 1 Disinfectants and DBP Rule.

Stage 1 Disinfectants and DBP Rule, health effects: See TTHMs (2950) and HAA5 (2456) for their specific health effects. Bromate is a probable human carcinogen (Group B2). Chlorite at elevated levels can cause hemolytic anemia, particularly in infants, developing fetuses, and individuals with certain enzyme deficiencies. Violations indicate the system exceeded one or more of these byproduct or disinfectant limits. Limit: TTHM: 0.080 mg/L; HAA5: 0.060 mg/L; Bromate: 0.010 mg/L; Chlorite: 1.0 mg/L

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.

Source: the U.S. EPA's Enforcement and Compliance History Online system (ECHO), which publishes the federal Safe Drinking Water Information System. EPA's terms and values are shown as published. The Colorado 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.
