While the Durham Region Health Department has released its first weekly beach report of the season, samples collected at three locations in Brock Township have been listed as unsuitable for testing.
The samples from the north and south beaches at the harbour, along with one from Thorah Centennial Park, were not tested by the Public Health Laboratory in Peterborough.
“This is due to elevated levels of debris in the water samples provided, which could be caused by high wave activity and muddy water at these beaches,” reads a media release from the health department.
Samples were not collected from three other locations — Bowmanville Beach East, Lakeview Beach West in Oshawa and Newcastle Beach Central – due to high water and debris in the area.
“The health department will continue to monitor access to these beaches in the coming weeks and begin normal sampling when the area is considered safe,” the media release reads.
None of the beaches in Durham have been posted as unsafe for swimming.
“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,” the media release reads.
