The boil water advisory applies only to those consuming water within the City of Kalamazoo’s Low and High pressure districts.

Customers should use bottled water or bring tap water to a rolling boil and boil for at least two minutes before using it for drinking, making ice, preparing food, brushing teeth, washing dishes, or other consumptive purposes, city officials said in a post.

There are no special precautionary measures for water used for bathing or showering, according to city officials.

E. coli is a bacteria that indicates that the water may be contaminated with human or animal wastes, according to health officials. They may pose a greater health risk for infants, young children, some of the elderly, and people with compromised immune systems.

City crews anticipate resolving the problem by Tuesday, Sept. 22.
