EPA issued the administrative order (Order) under section 1431 of the SDWA based on the determination of potential imminent and
substantial endangerment due to an E. coli maximum contaminant level (MCL) exceedance. The Order required the system to provide an alternate water supply, keep a boil water advisory posted, provide the EPA with a plan and schedule that outlines corrective actions to be taken to ensure there is no future E. coli contamination at the system, and perform necessary corrective actions.
