EPA data updated Oct 7, 2026

Consumer Confidence Rule

Other Violation

2 violations, Jul 2024 to open
EPA rule code 420 · 2 violations recorded, 2 still open

Other Violation: 2 violations, open since 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.

Monitoring and Reporting

1 violation, Jan 2024 to Oct 2025 · Asbestos
EPA rule code 333 · 1 violation recorded

Monitoring and Reporting: 1 violation, Jan 2024 to Oct 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.

Contaminant on the record: Asbestos.

Lead and Copper Rule Revisions

Reporting ViolationTreatment Technique Violation Health-based

2 violations, Oct 2024 to Jul 2025
EPA rule code 351 · 2 violations recorded, 1 health-based

Treatment Technique Violation, health-based: 1 violation, Oct 2024 to Jul 2025. The system did not carry out a required treatment process or corrective action.

Reporting Violation: 1 violation, Oct 2024 to Jul 2025. The system did not report required information on time.

What the rule requires: The 2021 LCRR updated the 1991 LCR with mandatory lead service line inventories and replacement planning, a new 'trigger level' at 10 ppb requiring optimization, and strengthened public education. The 2024 Lead and Copper Rule Improvements (LCRI) further requires replacing all lead service lines within 10 years.

Health effects: Same as Lead and Copper Rule (5000). Violations typically reflect failure to complete the required lead service line inventory or submit a required replacement plan. Lead service lines are the primary source of lead at the tap in many older systems. Limit: Lead action level: 15 ppb (trigger level: 10 ppb); copper action level: 1.3 mg/L

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.

The Oklahoma 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.
