Ottawa Beaches Water Quality

Every morning, the City of Ottawa Public Health Department takes a water quality sample to test for E. coli at each of the four beaches: Britannia Beach, Mooney’s Bay, Petrie Island, and Westboro Beach. If high concentrations of E. coli are detected, other disease-causing organisms are likely to be present and may pose a risk to your health. It’s important to monitor these results to ensure the safety of your children and yourselves.
