Other Violation15 violations, Sep 2024 to open · Public Notification Rule
Other Violation: 15 violations, 1 still open, Sep 2024 to open. 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.

Consumer Confidence Rule
Other Violation1 violation, Jul 2025 to open
Other Violation: 1 violation, open since Jul 2025. 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.

Stage 2 Disinfectants and Disinfection Byproducts Rule
Monitoring and Reporting2 violations, Jan 2025 to Dec 2025 · 2 contaminants
Monitoring and Reporting: 2 violations, Jan 2025 to Dec 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.
Contaminants on the record: Total Haloacetic Acids (HAA5), TTHM (Total Trihalomethanes).
Nitrate Rule

10 violations, Jan 2024 to Feb 2026
Nitrate Rule
Monitoring and Reporting10 violations, Jan 2024 to Feb 2026
Monitoring and Reporting: 10 violations, Jan 2024 to Feb 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: 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.

Radionuclides and Revised Rad Rule
Maximum Contaminant Level ViolationMonitoring and Reporting Health-based14 violations, Jul 2024 to Jun 2026 · 2 contaminants
Maximum Contaminant Level Violation, health-based: 9 violations, Jul 2024 to Jun 2026. A sample exceeded the maximum contaminant level EPA allows in drinking water.
Monitoring and Reporting: 5 violations, Jan 2025 to Mar 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.
Contaminants on the record: Combined Uranium, Combined Radium (-226 and -228).
Combined Uranium, health effects: Uranium poses both radiological and chemical health risks. Chronic exposure is primarily associated with kidney damage due to its chemical toxicity as a heavy metal. The radiological risk — increased cancer probability — is also present but secondary to the nephrotoxic concern at drinking water concentrations. There is no safe threshold for radiation exposure. Limit: 0.030 mg/L (30 µg/L)
Combined Radium (-226 and -228), health effects: Radium is a bone-seeking radionuclide that accumulates in skeletal tissue after ingestion. Long-term exposure increases the risk of bone cancer and leukemia. There is no safe threshold for ionizing radiation — the MCL is set at a level balancing risk reduction with treatment feasibility. Children are particularly vulnerable due to higher rates of bone growth and calcium uptake. Limit: 5 pCi/L (combined Ra-226 and Ra-228)
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.
