Stage 2 Disinfectants and Disinfection Byproducts Rule

Monitoring and Reporting

20 violations, Jul 2024 to Dec 2026 · 2 contaminants
EPA rule code 220 · 20 violations recorded, 2 still open

Monitoring and Reporting: 20 violations, 2 still open, Jul 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.

Contaminants on the record: Total Haloacetic Acids (HAA5), TTHM (Total Trihalomethanes).

Public Notice Rule and Revised PN Rule

Other Violation

23 violations, Aug 2025 to open · Public Notification Rule
EPA rule code 410 · 23 violations recorded, 23 still open

Other Violation: 23 violations, open since Aug 2025. A requirement other than monitoring, reporting, or a contaminant limit, such as public notice or the annual water quality report.

Contaminant on the record: Public Notification Rule.

Also violated in the past three years

Jul to Sep 2023 to Jul to Sep 2026

Revised Total Coliform Rule

Monitoring Violation

24 violations, Jul 2024 to Jun 2026
EPA rule code 111 · 24 violations recorded

Monitoring Violation: 24 violations, Jul 2024 to Jun 2026. 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.

The 90th percentile of the tap samples the system collected in its latest monitoring period, against EPA's action level. Levels vary between homes.

Lead 0.01 mg/L

Action level 0.015 mg/L · Jan to Dec 1998

Copper 1.39 mg/L

Action level 1.3 mg/L · Oct 1993 to Mar 1994

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.

Lead and copper are the newest 90th-percentile results in EPA's SDWA data download (LCR_SAMPLES, codes PB90 and CU90): for each monitoring period a system reports the 90th-percentile value of its tap samples, which EPA compares with its action level of 0.015 mg/L for lead and 1.3 mg/L for copper (40 CFR 141.80). A result is not a measurement of any one tap.

The Illinois 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.
