The water at beaches around Windsor and Essex County may not be as polluted as was previously thought.
On Thursday, scientists at the Great Lakes Institute for Environmental Research (GLIER) released findings of a regional, citizen-led sampling of water conducted last August.
Hundreds of residents sent in samples from areas including Point Pelee, Holiday Beach, the Detroit River and Sandpoint Beach.
University of Windsor professor Dan Heath said that even though the beaches were closed several times during the summer, there wasn't a lot of harmful bacteria in the water.
"I think [the health unit] errs on the side of caution, so the beaches may be closed when they don't have to be ... overall we're not finding any really scary pathogens popping up," he said.
In some areas, bacteria from goose poop was found in higher concentrations. It is not as harmful as human waste.
Heath cautions that the results only represent the conditions on a single day. He hopes to do the testing again this summer if funding is available.
