Edmonton's Mill Creek ranks worst for water quality in CreekWatch project

CreekWatch, a project of the RiverWatch Institute of Alberta, used 68 volunteers to regularly test water quality in 10 creeks last summer. Mill Creek ranked last for water quality, with high levels of salt, phosphorus and other pollutants. It’s E. coli bacteria count, measured weekly, was double the level found in Calgary’s troubled Nose Creek and more than four times the acceptable level for swimming.
