Further testing of south St. Vital water has shown it is safe to drink.
City officials late this afternoon released the results of a third-round of water sample testing done this week from the area where a boil-water advisory was imposed Tuesday night.
The results came back negative, again, for E.coli and total coliform bacteria.
"I assure residents that their tap water is safe and we have full confidence in our water treatment program," Diane Sacher, director of the City’s water and waste department, said. "The test results re-affirm that the water meets all health and safety water quality regulations and guidelines."
A boil-water advisory was imposed Tuesday night, the first time in the city’s history, for 12,500 Winnipeg homes in south St. Vital.
The advisory was imposed even though city and health officials believed the test results were a "false positive" – somehow caused by contamination of the samples either when they were collected or in the lab.
The first tests found traces of E.coli in two of three samples from the south St. Vital area, and traces of total coliform in the third sample from the same neighbourhood.
The advisory was lifted late Wednesday afternoon when a second test came back negative.
The city said it did more sampling in the same area Wednesday afternoon and the results came back today, again with no signs of E.coli or coliform bacteria.
Some people questioned the reliability of the second test results and the wisdom of lifting the advisory so quickly.
Sacher said the latest results support the decision to lift the advisory.
The city takes water samples on a weekly basis, every Monday, from 39 locations across Winnipeg.
