TUCSON, Ariz. (KGUN) — E. coli has been detected in one groundwater well in the Tucson area. That's according to a news release from the City of Tucson.

"One of our routine samples collected on Aug. 16, 2023, was total coliform positive," the news release stated. "This positive result is from a raw (untreated) water sample from one of the city's groundwater wells. Only treated water is served by the city's drinking water distribution system."

In the release, the city says that short-term health effects include diarrhea, cramps, nausea, headaches and other symptoms. They say to seek medical advice if experiencing any of these ailments.

"Users do not need to boil your water and there is no further action needed at this time," the release continued.

The city tells KGUN9 they are working to protect the water supply. Purging, disinfection, and more sampling of the well will take place next week to determine the extent and source of the issue.
