EPA v. Warm Springs WD EAO

Case summary

On June 26, 2026, EPA issued the emergency administrative order (Order) under section 1431 of the SDWA based on a determination of potential imminent and substantial endangerment due to an E. coli maximum contaminant level exceedance (MCL). A violation of the MCL for E. coli occurs if a system has any combination of a total coliform positive and E. coli positive routine and repeat samples. E. coli can cause symptoms such as diarrhea, nausea, cramps, headaches, and may pose a greater risk for infants, elderly, and immunocompromised individuals. The Order will require the system to provide an alternative water supply, maintain the existing boil water advisory, provide the EPA with a plan and schedule that outlines actions to be taken to ensure there is no future E. coli contamination at the system, and perform the necessary corrective actions. The system serves approximately 68 individuals at least 60 days a year.
