Beach Water Quality Results

Petrie Island Beaches remain closed until further notice. 

Water samples will be collected daily and tested for the presence of E.coli bacteria. When elevated levels of E.coli is detected in the water, it is probable that other disease causing organisms are also present.  These organisms can result in skin, ear, throat or gastro-intestinal illnesses.

Petrie Island Beaches remain closed until further notice.

Water test results are not available immediately as they take at least 18 hours to process in the laboratory.  For this reason, no-swim advisories are issued based on water sample results from the previous day and knowledge of water quality at each beach in previous years, and the impact of rainfall and bird activity on water quality.   Ottawa Public Health will issue a no-swimming advisory if:

  • the geometric mean of 5 water samples taken on the previous day is greater than 200 E. coli per 100mL of water; or
  • a single water sample test result from the previous day is greater than 400 E. coli per 100mL ; or
  • there is a significant rainfall event. 

Ottawa Public Health reminds residents and visitors to stay safe around lakes and rivers with outdoor recreational water safety tips
