Rainy summer brings water quality warnings for city beaches

While Ottawa's beaches aren't known for their crystal clear waters, high levels of rainfall this summer have resulted in near-recordwater quality warnings from public health officials.

Beaches at Mooney's Bay, Petrie East Bay, Petrie River and Britannia have had warnings for 62 days this summer as of Sunday.

Over the last 10 years at this point in the season,42 water quality warnings is averagemeaning this summer has seen50 per cent more warnings than usual.

"It's all about rainfall," saidJohnathan Wyatt, a health inspector with the city. "When we have an especially wet summer like we've been having, lots of contaminantsflow into our waters.

"You get all of the dog and geese poop from parking lots, parks and paths around floodinginto the water."

• Deluge of damage claims pouring in after flash floods cause sewage 'mayhem'

• Flooding is a problem. The 'sponge city' could be the solution

Ottawa faced more than 77 millimetres of rainfall on Thursday, resulting in sewage backups across the city.

"Sewer overflowscombined with natural creek runoffs can affect any of the beaches that are downstream from the city," Wyatt said, adding the only solution is time.

"You basically just have to wait for the water to keep flowingand water levels to go down."

Dangers of contaminated beaches

The city tests the swimming waterdaily for the presence ofE. colibacteria. When elevated levels ofE. coliare detected in the water, it's more likely that other disease-causing organisms are present, according to the city.

These organisms can result in skin, ear, throat or gastrointestinal illnesses.
