A boil water notice is in effect for homes and businesses in parts of Des Moines and Normandy Park after E. coli was detected in the water supply for King County Water District No. 54. Residents who reside within the notice area should bring their water to a rolling boil and allow it to cool before using it. Boiled or bottled water should be used for drinking, making ice, brushing teeth, washing dishes and preparing food until the notice is lifted, according to a release from the district. The water district takes weekly samples for testing, and a recent sample showed E. coli was present in the water. Follow-up samples showed coliform in the water, of which E. coli is a subspecies of, but the samples did not show E. coli. Coliform bacteria is commonly found in the environment but is not expected to be in public water systems, according to the water district.
