Daily Beach Water Quality Results

Daily testing of water quality at Ottawa beaches is over for 2016. Beaches are no longer supervised by lifeguards. Please exercise caution when visiting beaches.

For more information call Ottawa Public Health Information at 613-580-6744.

Recreational water samples are tested for the presence of E.coli bacteria. When elevated levels of E.coli are detected in the water, it is probable that other organisms - which can pose a risk to your health - are likely present. A no-swimming advisory will be issued if bacteria levels are over 200 E. coli per 100mL of water tested for one day; or if bacteria levels are over 100 E. coli per 100mL of water tested on two or more consecutive days. When a no-swim advisory is in effect, people should not swim due to the risk of getting a skin, ear, throat or even gastro-intestinal illness.

A 24-hour no-swim advisory may be in place at the beaches after significant rainfall.

*Please note Ottawa Public Health collects beach water samples every day. The results take 18 to 24 hours to process in the laboratory, and as such, swim and no-swim advisories are based on sample results taken from the previous day.
