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.
Water operators are ‘heroes’ behind the scenes
Across Canada, 29 Indigenous communities remain under a boil water advisory. Before residents in those communities can brush their teeth, drink a glass of water, cook food, or have a shower, they have to put water in a pot, bring it to a rolling boil, and let it cool — just so they don’t get sick performing many of these everyday activities. Under a commitment by the federal government to permanently eliminate all boil water advisories, 132 have been lifted in the last seven years. But until every Canadian has access to clean, potable drinking water, there is still much work to do, said Steph Romaniuk, faculty in the School of Environmental Studies at Canadore College in North Bay.
