Beach Water Quality Results

August 29, 2022 - Water testing at Ottawa beaches is now over for the season. The City of Ottawa no longer has supervised swimming at these public beaches.

Beach Water Quality Testing at the City of Ottawa Supervised Beaches

Water samples will be collected daily from City of Ottawa supervised beaches between June 18 and August 28, 2022 and tested for the presence of E. coli bacteria. When elevated levels of E. coli are detected in the water, it is more likely that other disease-causing organisms are also present. These organisms can result in skin, ear, throat or gastro-intestinal illnesses. 

Beaches and COVID-19 Transmission

Swimming at the City of Ottawa public beaches is not considered to be an important risk for transmission of COVID-19.  Water is not a favoured route of transmission for the virus that causes COVID-19. This virus preferentially transmits short distances (up to two metres) through the air by respiratory droplets from an infected person (from coughing, sneezing, shouting, singing, talking, breathing), by direct  contact with an infected person or by contact with a surface that an infected person has touched (and now, contaminated fingers bringing the virus to your eyes, nose or mouth).

To minimize transmission of COVID-19 when at a public beach or park:

• Practice physical distancing from others in changerooms, washrooms and wear a mask for added protection in areas you cannot maintain at least two metres from others not in your group. 
• When in the water, on the shorelines and enjoying the park and picnic areas, practice physical distancing. While the risk of transmission of COVID-19 is much less outdoors than indoors, when there is significant crowding, as there could be at a pool or beach, there is greater concern about spread.
• Physical distancing, wearing face masks, staying home when sick, and practicing good hand hygiene remain the best way to prevent the spread of the virus. 

Beach water test results 

Water test results are not available immediately as they take at least 18 hours to process in the laboratory. For this reason, swim advisories are issued based on water sample results from the previous day, as well as our knowledge of water quality at each beach in previous years and how they react to factors such as rainfall and bird activity. Ottawa Public Health will not recommend swimming at beaches if: 

• the geometric mean of 5 water samples taken on the previous day is greater than 200 E. coli per 100mL of water (Ontario water quality standard for beach water quality);
• there is a significant rainfall event; or
• we are aware of a situation that could impact the water quality at a beach.
