Boil Water Order Issued for Humboldt After E. coli Detected

The City of Humboldt has issued a boil water order after E. coli bacteria were found in the municipal water system during November 2025. The detection requires the city to investigate and correct potential problems within the treatment or distribution system.

According to the notice, E. coli contamination indicates the possible presence of human or animal waste in the water supply. Exposure may lead to diarrhea, cramps, nausea, headaches or other symptoms. The advisory states that infants, young children, some elderly residents and people with compromised immune systems may face higher health risks. Residents with medical concerns are encouraged to contact a physician.

The city is instructing all residents to boil water before drinking. Water should be brought to a boil for one minute and cooled before use. Bottled water is also acceptable. The advisory states that boiled or bottled water should be used for drinking, making ice, brushing teeth, washing dishes and food preparation until further notice.

The notice explains that contamination can occur following heavy runoff, a break in water lines or a failure in the treatment system. Testing is ongoing and officials are working to identify the source. The city will notify residents when the boil order is lifted. The expected resolution date is December 5, 2025.

Corrective action includes disinfection of the water system.

Free bottled water distribution will take place at the City Maintenance Shop at 115 Longbranch St. beginning November 26 from 4 p.m. to 6 p.m. daily, while supplies last. There is a limit of one case per family.

Questions can be directed to operator Mike Adair at 402-677-3781.

Residents are asked to share this information with anyone who may not have received the notice, including those living in apartments, nursing homes, schools and businesses.
