(AP Photo/Kevin Frayer, File) Groups Renew Plea to U.S. Secretary of State to Oppose Threat to Drinking Water Supply for 40 Million People NEW YORK, NY – May 27, 2015 – Environmentalists in the Great Lakes Basin are opposed to a new report from a Canadian Joint Review Panel that has called for the support of the Canadian Minister of the Environment to approve a deep geological repository for nuclear waste in Kincardine, Ontario due to its proximity to drinking water supplies for 40 million people in the United States and Canada. The proposed plan from Ontario Power Generation (OPG) is to store underground radioactive nuclear waste less than one mile from the shores of Lake Huron. Canadian officials are getting closer to approving this hazardous project and could even fast track the authorization of a final license within the next few months. Under the Binational Great Lakes Water Quality Agreement (amended in 2012), both Canada and the US acknowledge the importance of anticipating, preventing, and responding to threats to the waters of the Great Lakes. Both countries share the responsibility and obligation to protect these shared waters from pollution. “Great Lakes Waterkeepers and Waterkeeper Alliance oppose this project, which could threaten the drinking water supply of 40 million Americans and Canadians,” said Bob Burns, Detroit Riverkeeper. “We ask the U.S. State Department to stand with the citizens, local and state governments, and other stakeholders in the Great Lakes Basin whose voices have not yet been heard but who are at risk if the deep geological repository fails.” Perfume chemists have devised a tool aimed at stopping foul smells from undermining the struggle to improve sanitation in developing countries. A team from Swiss firm Firmenich—better known for applying aroma expertise to perfumes and food—has developed a system to quantify six major faecal aroma chemicals at the same time in toilet air. The technique is described in a paper published in Environmental Science & Technology last month. “This is to help make a perfume to cover the malodour,” Christian Starkenmann, a chemist at Firmenich and one of the study’s authors, said. Such perfumes would improve conditions in public toilets that charge for use, supporting a business model for building and maintaining sanitation where it is lacking, he added. Clara Rudholm, a programme officer at the Global Sanitation Fund in Geneva, said the study was useful, while stressing the importance of supporting behaviour change in local communities, too. The Firmenich scientists analysed sludge from latrines in India, Kenya, Uganda and South Africa. They were unable to collect a fully representative toilet smell using the first method they tried: Holding a polymer-coated needle above the sludge to absorb odorant chemicals. Specifically, this technique could not capture sulphur-containing gases. “What you smell in the toilet is the air, not the sludge,” Starkenmann said. “To analyse the air is much more difficult.” Instead the team designed a system that pumps air from above the latrine through a water-based solution that traps sulphur-containing gases. Other odorant compounds also dissolve in the water. The scientists ran the water through two extraction steps that collected all the odorants. They then got 40 Firmenich 8 Africa Water, Sanitation & Hygiene • July - August 2015
