After 6 days, last boil water advisory lifted on the south shore of Montreal – Montreal

A boil water advisory issued last week in several Montreal suburbs was completely lifted after authorities in Boucherville, Que., said the water was now safe to drink.

The advisory had been in effect in Longueuil, Que., and the neighboring municipalities of St-Bruno-de-Montarville and Boucherville since last Friday after E. coli bacteria were found in the water supply.

Longueuil, which runs the water treatment plant that serves other communities, issued the advisory after a single sample tested positive for E. coli on Friday.

After tests, Longueuil lifted its advisory on Sunday and St-Bruno did the same on Monday, but Boucherville was awaiting the results of its own tests for part of the municipality.

According to provincial standards, two samples over two days must be free of contaminants for the advisory to be removed.

Health officials in the Montérégie region, where the communities are located, say no cases of illness have been reported.
