ENVE 410L: Environmental Technology in the Developing World is a course at Yale University based on the practical application of environmental engineering fundamentals to solve real-world environmental and human health problems in underdeveloped regions of the world and providing students with international, hands-on learning experience. The class will exercise various problem-based practices to define and solve problems related to water and wastewater treatment, water and air quality monitoring and control, subsurface remediation, and hygienic infrastructure such as latrine. We are among the first few students to travel to Nicaragua with Professor Jaehong Kim and to explore solutions to environmental problems that people in Nicaragua are facing!
