The city of Langley has detected E. coli bacteria in the water supply and is advising its citizens to boil their water for at least one minute before using or consuming it.

According to a notice from the city, boiled or purchased bottled water should be used for drinking, making ice, brushing teeth, washing dishes and food preparation until further notice.

E. coli can cause people to feel sick and experience short-term effects such as diarrhea, cramps, nausea, headaches or other symptoms.

Routine monthly testing revealed the presence of the bacteria at a sample location on the western section of the water system, the notice stated.

Langley will be increasing the chlorination of water in the system to eliminate the bacteria. The city’s wells and other locations have been tested and came back negative.

Testing will be completed at 10 other locations within the next two days. The city estimates the problem may be resolved by Friday.
