A massive dumpsite lies in the heart of the municipality of Kanifing. Kanifing sits on the Republic of The Gambia’s Atlantic Coast and is one of the West African country’s eight local government areas. Kanifing, which is near the capital city of Banjul, is home to nearly 500,000 people. The Bakoteh Dumpsite takes up roughly 18 hectares. What was once a quarry has, for decades, been used as an unregulated landfill. Now, as the Kanifing Municipal Council looks to remediate the site, it is seeking advice from James Tinjum, a University of Wisconsin-Madison associate professor of civil and environmental engineering and director of the department’s Geological Engineering Program, and his students.
