Still in violation

EPA data updated Oct 7, 2026

E. coli (Escherichia coli)

E. coli is a fecal indicator bacterium.
EPA rule code 3014 · Microbial

What it means: E. coli is a fecal indicator bacterium. Its presence in treated water is an acute health violation, meaning the system must notify customers within 24 hours. Detection requires immediate corrective action — typically a boil water advisory, investigation of contamination source, and system flushing.

Health effects: Most E. coli strains cause diarrheal illness. Some strains (e.g., O157:H7) produce toxins causing severe bloody diarrhea, hemolytic uremic syndrome (HUS — a form of kidney failure), and death — especially in children under 5 and the elderly. Even non-pathogenic strains in drinking water indicate that disease-causing organisms may also be present.

Limit: Zero (one confirmed positive sample = acute MCL violation)

Nitrate

Nitrate (NO₃) is the most common chemical contaminant in US groundwater, entering from fertilizers, septic systems, and animal waste.
EPA rule code 1040 · Inorganic Chemical

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)

About this contaminant
About 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.

Service area from EPA's Public Water System Service Area Boundaries dataset: location confidence LOWER. The system's location is the centre of the service area EPA publishes for the system.

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 Idaho 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.
