We appear to be running into infrastructure problems in a city with almost 700,000 residents. Via CBC News: Winnipeg-wide boil water advisory in place. Excerpt:
The city of Winnipeg is under a boil water advisory Tuesday night after tests confirmed the presence of E. coli.
The Winnipeg Regional Health Authority originally said in a press release the advisory was for an area east of the Red River.
The release said the advisory was being issued "as a precautionary measure as a result of two clusters of positive results involving the presence of E. coli, received earlier today."
"There has been no source of contamination identified to date; however, public health is proceeding according to provincial and national guidelines. These guidelines specify to issue the advisory as a precautionary measure, while investigating the possible causes."
At a press conference around 6 p.m. the city revised those concerns and has now extended the advisory across the city.
