ORIGINAL POST: PORTLAND — Portland officials issued a citywide boil notice after state health officials detected E. coli in the water supply.
The Portland Water Bureau said residents should boil for at least one minute all tap water used for drinking, food preparation, tooth brushing and ice.
Ice or any beverages prepared with unboiled tap water on or after Tuesday should be dumped.
The water samples that tested positive for bacteria were collected from two reservoirs at Mount Tabor.
Tri-County Health Officer Dr. Paul Lewis says the E. coli is unlikely to cause any health problems, except for maybe diarrhea.
The Water Bureau is investigating the cause of the contamination.
