Rules violated in the past three years

Jul to Sep 2023 to Jul to Sep 2026

Revised Total Coliform Rule

Monitoring Violation

2 violations, Sep 2023 to May 2025
EPA rule code 111 · 2 violations recorded

Monitoring Violation: 2 violations, Sep 2023 to May 2025. 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

Surface Water Treatment Rule

Monitoring and Reporting

2 violations, Apr 2025 to Jul 2026
EPA rule code 121 · 2 violations recorded

Monitoring and Reporting: 2 violations, Apr 2025 to Jul 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.

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 Washington 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.
