Still in violation
EPA data updated Oct 7, 2026
Consumer Confidence Rule (CCR)
Community water systems must deliver an annual water quality report (Consumer Confidence Report) to all customers by July 1, covering the previous year.
Consumer Confidence Rule (CCR)
Community water systems must deliver an annual water quality report (Consumer Confidence Report) to all customers by July 1, covering the previous year.
What it means: 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.
Health effects: No direct health risk — this is an administrative transparency obligation. Failure means customers lack information to make informed decisions (e.g., whether to use bottled water for infants when lead is elevated).
Limit: No MCL — this is a reporting requirement
About this rule
E. coli (Escherichia coli)
E. coli is a fecal indicator bacterium.
E. coli (Escherichia coli)
E. coli is a fecal indicator bacterium.
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)

Lead and Copper Rule Revisions (LCRR)
The 2021 LCRR updated the 1991 LCR with mandatory lead service line inventories and replacement planning, a new 'trigger level' at 10 ppb requiring…
What it means: The 2021 LCRR updated the 1991 LCR with mandatory lead service line inventories and replacement planning, a new 'trigger level' at 10 ppb requiring optimization, and strengthened public education. The 2024 Lead and Copper Rule Improvements (LCRI) further requires replacing all lead service lines within 10 years.
Health effects: Same as Lead and Copper Rule (5000). Violations typically reflect failure to complete the required lead service line inventory or submit a required replacement plan. Lead service lines are the primary source of lead at the tap in many older systems.
Limit: Lead action level: 15 ppb (trigger level: 10 ppb); copper action level: 1.3 mg/L
About this ruleAlso violated in the past three years

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.
Service area from EPA's Public Water System Service Area Boundaries dataset: Random Forest method, Federal agency. The system's location is the centre of the service area EPA publishes for the system.

The Oklahoma 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.
