Interim and Long Term 1 Enhanced Surface Water Treatment Rule
Monitoring and ReportingTreatment Technique Violation Health-based18 violations, Feb 2024 to Jul 2026 · Interim Enhanced Surface Water Treatment Rule
Monitoring and Reporting: 17 violations, 1 still open, Feb 2024 to open. The system did not complete required monitoring, or did not report the results on time. This does not show that a contaminant was found.
Treatment Technique Violation, health-based: 1 violation, May 2025 to Jul 2025. The system did not carry out a required treatment process or corrective action.
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
Surface Water Treatment Rule
Monitoring and Reporting
2 violations, Jun 2025 to Jul 2026
Surface Water Treatment Rule
Monitoring and Reporting2 violations, Jun 2025 to Jul 2026
Monitoring and Reporting: 2 violations, 1 still open, Jun 2025 to open. 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.

Ground Water Rule
Treatment Technique Violation Health-based1 violation, Jul 2024 to Apr 2025
Treatment Technique Violation, health-based: 1 violation, Jul 2024 to Apr 2025. The system did not carry out a required treatment process or corrective action.
What the rule requires: The 2006 GWR requires regular sanitary surveys of groundwater systems and targeted corrective action when fecal indicators are found in source water. Systems with significant deficiencies must provide 4-log virus treatment (99.99% removal/inactivation) or fix the deficiency.
Health effects: Protects against enteric viruses, which can contaminate groundwater via cracked well casings, failing septic systems, or animal waste. Viruses persist longer in groundwater than in surface water. Hepatitis A and norovirus are the primary pathogens of concern. Limit: Treatment technique: 4-log virus treatment required when source water has fecal indicators or significant sanitary deficiencies
About this rule
Nitrate Rule

Nitrate Rule
Monitoring and Reporting1 violation, Jan 2024 to Jan 2025
Monitoring and Reporting: 1 violation, Jan 2024 to 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: Nitrate (NO₃) is the most common chemical contaminant in US groundwater, entering from fertilizers, septic systems, and animal waste. It is odorless and tasteless — the only way to know if it's present is to test.

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.
