Beach Testing for E. coli

The health unit samples 9 beaches during June, July, and August. At least five water samples are collected at each beach and are sent to an Ontario Public Health Laboratory for bacterial analysis. The water samples are tested for E.coli. E.coli is used as an indicator for disease causing organisms such as bacteria and viruses that may be present in the beach water.

Before swimming always be aware of recent weather and read the signs posted on the beach.

Beach Water Sampling is done in June, July, and August and will be posted on Fridays.
