Whitby: The following represents beach-posting information for Durham Region beaches. Test results for the week of July 22 indicate that one beach has been posted as unsafe for swimming due to elevated bacteria levels.
Beaches are posted as unsafe for swimming when elevated levels of E. coli exceed the Provincial standard of 200 E. coli per 100 ml of water.
The Health Department reminds the public not to swim in beach water for at least 48 hours after heavy rainfall, as bacteria levels can increase due to run-off.
Throughout the summer, the Health Department conducts bacteriological water tests to determine if these beaches are safe for swimming. The Public Health Ontario Laboratory in Peterborough provides analysis of all water samples submitted for testing.
