Still in violation
EPA data updated Oct 7, 2026
Groundwater Rule (GWR)
The 2006 GWR requires regular sanitary surveys of groundwater systems and targeted corrective action when fecal indicators are found in source water.
Groundwater Rule (GWR)
The 2006 GWR requires regular sanitary surveys of groundwater systems and targeted corrective action when fecal indicators are found in source water.
What it means: 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 (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 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.
