Public Notification Rule
When a system violates a drinking water standard, it must notify customers promptly: within 24 hours for acute violations (e.g., E. coli), 30 days for…
What it means: When a system violates a drinking water standard, it must notify customers promptly: within 24 hours for acute violations (e.g., E. coli), 30 days for non-acute MCL violations, and 1 year for monitoring failures. A violation means the notification was late or missing — not that the underlying water issue is necessarily severe.
Health effects: No direct health risk from the notification violation itself, but delayed notification means customers may have consumed contaminated water without the chance to take protective action (boil water orders, bottled water use).
Limit: No MCL — compliance requires meeting specific notification deadlines

Nitrate
Nitrate (NO₃) is the most common chemical contaminant in US groundwater, entering from fertilizers, septic systems, and animal waste.

What it means: 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)

Nitrite
Nitrite (NO₂) enters water from fertilizer runoff, septic systems, and natural mineral deposits.
Nitrite
Nitrite (NO₂) enters water from fertilizer runoff, septic systems, and natural mineral deposits.
What it means: Nitrite (NO₂) enters water from fertilizer runoff, septic systems, and natural mineral deposits. Unlike nitrate, nitrite acts very quickly in the body — it converts hemoglobin to methemoglobin, which cannot carry oxygen. Nitrite can also form in distribution systems through microbial nitrification when chloramine disinfection breaks down.
Health effects: Methemoglobinemia ('blue baby syndrome') in infants under 6 months: reduced oxygen delivery to tissues can be life-threatening. Pregnant women and people with glucose-6-phosphate dehydrogenase (G6PD) deficiency are also at elevated risk. Adults are generally less susceptible due to more effective methemoglobin reduction.
Limit: 1 mg/L as nitrogen (NO₂-N)
About this contaminant
Revised Total Coliform Rule (RTCR)
The 2013 RTCR (effective 2016) replaced the original TCR.
Revised Total Coliform Rule (RTCR)
The 2013 RTCR (effective 2016) replaced the original TCR.
What it means: 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.
Health effects: Total coliform bacteria indicate that the disinfection barrier has been breached or fecal contamination is entering the system. E. coli specifically indicates fecal contamination and the possible presence of disease-causing pathogens (norovirus, Salmonella, Shigella, Campylobacter). Illness can be severe in elderly, young children, and immunocompromised individuals.
Limit: Zero E. coli; ≤5% of monthly samples total coliform-positive
About this contaminantAbout this data
EPA counts the rules a system was in violation of, not the individual violations; one rule can carry several in the same period. Unresolved means still in violation at EPA's latest data refresh. Measured contaminant levels are not part of this record; each system publishes them in its annual Consumer Confidence Report.

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.
