FOLEY, Minn. (KNSI) - Residents of Foley were warned to avoid drinking tap water over the weekend after E. Coli contamination was detected in the city's water supply Friday, the city announced.
The discovery was made by city water monitoring systems Friday afternoon, according to an alert issued by the city. The problem was attributed to a possible failure of chlorination pumps at the city's wells.
While chlorination had been restored by Friday afternoon, the results of further re-testing by the Minnesota Department of Health were not expected until early next week.
All drinking water coming from Foley's faucets should be boiled before use.
A statement posted to the city's website reported the anticipated resolving the problem within a week.
Any water being used should be brought to a boil for one minute before it's used for drinking, making ice, brushing teeth, washing dishes or any food preparation.
According to the Minnesota Department of Health, bacterial contamination of the water was possibly through several means, including increased run-off entering the drinking water source, a break in water transmission pipes or the intrusion of waste water through a break in a well casing pipe.
E. coli contamination can cause severe stomach cramping, diarrhea, nausea and vomiting.
