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.
Canada invests $3.1 million to protect the Great Lakes and launches new call for proposals
The Great Lakes are essential to the health and well-being of millions of Canadians for safe water supply and the sustainability of our ecosystems. Protecting one of the largest surface freshwater systems in the world is vital, which is why the Government of Canada is collaborating with local partners to find the best ways to keep water safe, clean, and well-managed.
World Water Day 2021 highlights dire predictions of growing scarcity
About four billion people experience severe water shortages for at least one month a year, and around 1.6 billion — almost a quarter of the world's population — have problems accessing a clean, safe water supply, according to the United Nations. While the UN's sustainable development goals call for water and sanitation for all by 2030, the international organization says scarcity is increasing and more than half the people on Earth will be living in water-stressed regions by 2050.
