A public health advisory was posted at Cadboro Bay beach after Tuesday’s heavy rain caused two short outfalls to overflow and discharge about 5,000 cubic metres of diluted sewage in the area.
Two discharges at the outfalls just south of Cadboro Bay beach lasted about 20 minutes and 60 minutes each, said Cam Preece, manager of core area operations with the Capital Regional District’s integrated water services.
Results of shoreline water testing showed higher than normal fecal coliform levels, which can make the water unsafe for swimming.
After consulting Island Health and municipalities, CRD posted public health advisory signs warning people to avoid the water.
The CRD plans to collect more samples today.
The advisory will remain until followup sample results are below the acceptable recreational limit of 200 fecal coliform per 100 millilitres of water.
Two major downpours on Tuesday saw 27 millimetres of rain fall at the University of Victoria, breaking the precipitation record for Sept. 2.
