Early algae blooms are to blame for the musty water some people are noticing in Regina and Moose Jaw these days, according to experts at the Buffalo Pound water treatment plant, which services both cities. Blair Kardash, the plant's manager of laboratory and research, told CBC News his team first detected the "odour materials" from the growing algae in Buffalo Pound Lake — where the water comes from before it's filtered — at the end of April.
