Ground Water Rule
Other ViolationTreatment Technique Violation Health-based3 violations, Jan 2025 to open
Treatment Technique Violation, health-based: 2 violations, open since Apr 2025. The system did not carry out a required treatment process or corrective action.
Other Violation: 1 violation, Jan 2025 to Feb 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: The 2006 GWR requires regular sanitary surveys of groundwater systems and targeted corrective action when fecal indicators are found in source water. Systems with significant deficiencies must provide 4-log virus treatment (99.99% removal/inactivation) or fix the deficiency.
Health effects: Protects against enteric viruses, which can contaminate groundwater via cracked well casings, failing septic systems, or animal waste. Viruses persist longer in groundwater than in surface water. Hepatitis A and norovirus are the primary pathogens of concern. Limit: Treatment technique: 4-log virus treatment required when source water has fecal indicators or significant sanitary deficiencies

Revised Total Coliform Rule
Monitoring ViolationReporting Violation2 violations, Jul 2023 to Apr 2024
Monitoring Violation: 1 violation, Jul 2023 to Oct 2023. The system did not complete required monitoring. This does not show that a contaminant was found.
Reporting Violation: 1 violation, Mar 2024 to Apr 2024. The system did not report required information on time.
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.

Nitrate Rule
Maximum Contaminant Level Violation Health-based3 violations, Jan 2023 to Apr 2026 · 3 measured values
Maximum Contaminant Level Violation, health-based: 3 violations, Jan 2023 to Apr 2026. A sample exceeded the maximum contaminant level EPA allows in drinking water.
Limit 10 MG/L · Jan to Dec 2026
Limit 10 MG/L · Jan to Dec 2025
Limit 10 MG/L · Jan to Dec 2023
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.
Health effects: Methemoglobinemia in infants under 6 months: gut bacteria convert nitrate to nitrite, which blocks oxygen transport in blood. Pregnant women should also take precautions. Chronic adult exposure at elevated levels may increase cancer risk. Limit: 10 mg/L as nitrogen (NO₃-N)
About this ruleAbout 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 system's location is the centre of the first town EPA lists the system as serving, from Census Bureau place files.
Source: the U.S. EPA's Enforcement and Compliance History Online system (ECHO), which publishes the federal Safe Drinking Water Information System. EPA's terms and values are shown as published. The Indiana 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.
