On May 16, EPA issued the 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, keep the boil water advisory posted, 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.
