Two advisories, one for blue-green algae and another for fecal bacteria levels, have now been issued for the waters of Lac La Biche lake in the days leading up to the Canada Day weekend. Alberta Health Services (AHS) officials issued a blue-green algae advisory on Thursday, warning that areas of the lake were affected by an outbreak of the naturally-occurring bacteria that can appear on the surface as a green, blue, pink or brown-tinged "scum" or "glob". Human contact with blue-green algae can cause irritation to skin and the eyes. It can also cause nausea and diarrhea. The symptoms are more prominent in children, and can appear within a few hours of water contact. Ingestion of water with the bacteria can be fatal to pets.
Grade 5 science project leads to water quality testing at school in northern Quebec
"They did find that we should be filtering our water in the schools," she said, adding that the band office has agreed to carry out further tests. Roy said the quality of the water source, Mistissini Lake, is very, very good, but down the line in the school the water quality drops noticeably. The students also studied four different types of filtering options, including some traditional methods, such as using moss or a heavy cotton, as well as modern charcoal filters. In their evaluation, the students also took into account cost and environmental impacts of the different filtration methods.
Algae flare-up blamed for Calgarians' lingering smelly tap water
Dawn Stewart said she’d never encountered the foul flavour of her home’s tap water until she filled up a glass a few weeks ago. “It was disgusting and I said ‘does it taste like there’s dirt in it?'” “I ran the water for a bit and it was worse — even when I’ve got soap in it, it still has that musty odour.” With no water filters in her Royal Oak home, Stewart said the water’s earthy flavour is a disincentive to drinking it. And initially, she wondered if consuming it posed a health risk.
