**We have ended our regular beach water testing for the year. Sampling will resume again in May 2020.**


Southwestern Public Health conducts weekly water quality testing at public beaches from June - Labour Day.

Beach water quality results are updated each week in the tables below and will be posted on Southwestern Public Health’s Twitter and Facebook pages.


How to read the beach water sampling results:

RED = High levels of bacteria may pose a health risk. It is not safe to swim.

GREEN = The last water sample taken did not show harmful levels of bacteria, but remember that weather or other factors may have changed water quality since then. 

Blank = No current sample to report

About beach water testing

Water is tested for E. coli  bacteria, which is an indicator that there is fecal contamination present from either animal or human or both.

E. coli, as well as the presence of other disease-causing organisms, can cause intestinal illness or infections of the eyes, ears, nose or throat.

Weather conditions can also adversely affect water quality. If the water is cloudy from rough water or heavy rains, it may have high levels of bacteria for up to two days. The public is advised to consider recent weather conditions when deciding on whether or not to go swimming.

If water results show a public beach is unsafe for swimming, a warning sign is posted at the beach to indicate the water may pose a risk to your health and swimming is not recommended.

The recreational water quality guideline of 200 E. coli  per 100 ml of water is set jointly by the Ministry of Environment and the Ministry of Health & Long-Term Care.

Learn more about how water samples are collected (MOHLTC).
