How come recently Westboro Beach has been closed for the high levels of E.coli but Petrie Beach remains open with low levels.
July 9th Beach Water Sampling Results:
Westboro: 378
Mooney's Bay: 16
Petrie Island East Bay: 24
Petrie Island River Beaches: 34
A beach is closed for swimming when the e.coli is higher than 200per 100ml of water as per Ontario water quality standard for beach water quality.

To be honest, that's always been my perspective as well.
Now I don't know if there's a pattern showing that the water quality at Petrie is overall better than Westboro, but I suspect the placement of water treatment plants and combined sewer outlets in both Ottawa and Gatineau might have an effect.
Here's a 12 page report I found on combined sewer overflow in the region. I have not read it yet, but it might provide some insight (?)
