Rules violated in the past three years

Jul to Sep 2023 to Jul to Sep 2026

Interim and Long Term 1 Enhanced Surface Water Treatment Rule

Treatment Technique Violation Health-based

2 violations, Sep 2023 to Apr 2024 · Interim Enhanced Surface Water Treatment Rule
EPA rule code 122 · 2 violations recorded, 2 health-based

Treatment Technique Violation, health-based: 2 violations, Sep 2023 to Apr 2024. 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

3 violations, Oct 2023 to Apr 2024
EPA rule code 121 · 3 violations recorded

Monitoring and Reporting: 3 violations, Oct 2023 to Apr 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: 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.

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.

The Texas 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.
