CEAE Professor Dr. Karl Linden and his students Christie Chatterley and David Sparkman continued their work in water sustainability development and sanitation projects in Peru during the summer of 2010. The projects partner ¶¶ÒõÂÃÐÐÉä-Boulder faculty and students with two Peruvian universities, local organizations, and disadvantaged communities in Peru. Research trips were conducted to assess the success and sustainability of the water and sanitation infrastructure in small rural communities. Teams of faculty and students spent time in the communities conducting water quality analysis and structural inspections, and interviewing local citizens to learn about the water and sanitation needs and desires of the communities. Research results and recommendations were shared with local organizations to help them to continue to improve water and sanitation programs. ¶¶ÒõÂÃÐÐÉä and local high school students also benefit from the sustainability project. Student design projects in Professor Linden’s Water, Sanitation, and Hygiene (WASH) course at ¶¶ÒõÂÃÐÐÉä-Boulder include designing a low-cost household water filter and an ecological sanitation latrine based on the Peru community feedback. The research also is shared with students at Centaurus High School in Lafayette through a weeklong water treatment design challenge and class presentations to give the high school students exposure to engineering challenges in the developing world.
