All five of the city’s urban beaches have been placed under a no-swim advisory.
Mooney’s Bay, Britannia Beach, Westboro Beach, Petrie Island East Bay and Petrie Island river beaches were all covered by the advisory Saturday, prompted by heavy rainfall. The advisory was initiated on Friday, when the city logged 18 mm of rain. The city issues advisories if if bacteria levels are over 200 E. coli per 100 mL of water tested for one day or if bacteria levels are over 100 E. coli per 100 mL of water tested on two or more consecutive days. Those who swim during an advisory are at risk of getting a skin, ear, throat or gastro-intestinal illness, the Ottawa Public Health warns.
