Securing a safe water supply for Earth’s growing population is a global goal that is reflected in the long-term sustainability plans of almost every nation. Creatively solving this problem is another matter altogether. University of Saskatchewan graduate student Bernd Steiger is using chemistry expertise and Saskatchewan-based waste to soak up contaminants in fresh water reserves. “This province can be considered the breadbasket of Canada with its large agricultural sector,” Steiger noted. “Agro-waste (such as the inedible part of a plant, for example) is a low-value byproduct of agriculture, and turning this waste material into specialty adsorbents can aide in generating additional wealth for the Sask. agro-economy, while also serving to address water security and sustainability goals.” Steiger’s work uses several principles of what is referred to as ‘green chemistry’ — a type of chemistry that avoids a need for conventional chemical or energy inputs.
Wastewater study shows COVID levels are down in Saskatoon, but up in North Battleford
COVID-19 viral loads in wastewater are up in North Battleford, Sask., but down in Saskatoon, the most recent data from the University of Saskatchewan shows. Since the summer of 2020, a group of researchers from the U of S have analyzed wastewater samples from Saskatoon, North Battleford and Prince Albert in search of traces of the COVID-19 virus. However, data is not available from Prince Albert this week because researchers only received one sample from the city's wastewater, which was delivered late, according to an email from wastewater project manager Femi Oloye.
Q+A: U of S water expert delivers talks to COP27 climate conference
John Pomeroy, director of the Global Water Futures program at the University of Saskatchewan is delivering virtual talks on glacier preservation and water issues in the circumpolar North to delegates at the COP27 climate summit. He spoke with Postmedia ahead of his second lecture, set to be delivered Wednesday. Q: What are some key points from your talks? A: Warming is proceeding faster in the mountains than other parts of the world. Glaciers are retreating, snowpacks are melting earlier in the year. We’re also getting extremely high temperatures, such as in 2021, and massive forest fires in areas as well as flash-flooding coming form heavy rainfall at times. All these are occurring at once, which is making it very challenging.
New spike in wastewater COVID-19 viral loads concerns researchers at U of S
After almost a month of declining numbers, researchers at the University of Saskatchewan say they have seen a jump in COVID-19 viral load in samples taken from wastewater treatment plants in Saskatoon, Prince Albert and North Battleford. On Monday, researchers at Global Water Futures at the U of S said that evidence of COVID-19 had increased in Saskatoon by 51 per cent compared to the week before. Meanwhile, Prince Albert saw an increase of 86 per cent and North Battleford saw an increase of 58.7 per cent.
Saskatchewan waste water teams consider testing for polio, monkeypox
Saskatchewan researchers scanning sewers for COVID-19 may soon be on the lookout for other viruses. Wastewater epidemiology teams in Saskatoon and Regina are considering searching for monkeypox and polio, two viruses that are on the rise in North America. “Basically, we’re trying to translate what we’ve done for the SARS-CoV-2 methodology and see how well it works for these other viruses,” said University of Regina biology professor Tzu-Chiao Chao. Wastewater testing looks for traces of viruses or other contaminants in sewage.
Latest U of S wastewater study shows continued spike in Saskatoon COVID-19 samples
The most recent study from the Global Institute for Water Security at the University of Saskatchewan shows a growing trend of COVID-19 RNA in its wastewater samples. On Monday, the Institute released its weekly report, showing the city's wastewater saw a 118 per cent increase in viral RNA from July 29 to August 4, compared to a week before. Previously, the wastewater studies were able to predict rising numbers of COVID-19 in the city through traces of the virus found in the city's sewage.
‘Rapid and dramatic change’: U of S project aims to improve climate change predictions in western, northern Canada
The University of Saskatchewan (U of S) is hoping to improve western and northern Canada climate change predictions. Findings from the Changing Cold Regions Network (CCRN) – a collaboration between several universities, led by the U of S – suggest that climate change is making future extreme weather events difficult to predict. These disasters, such as wildfires or floods, will likely become more common and more severe, according to U of S research associate Chris DeBeer, the science manager for CCRN.
Young Innovators: New U of S app tracks causes of algae bloom
A new University of Saskatchewan smartphone app will help farmers and communities identify hotspots of nutrient contamination in freshwaters and possibly predict where algae blooms — slimy, plant-like green organisms that hinder water quality — are likely to grow. “Tracking how and where agricultural nutrients, which help crops grow, may be washed away with rainfalls and snowmelt is a major concern for both researchers and the public, and that’s where our app comes in,” said Environment and Climate Change Canada scientist Diogo Costa.
