Beneath Ghana’s rich soils lies a treasure the world desires––gold. The rush to unearth this precious metal has led to a host of health problems from illegal mining, or galamsey. This unregulated, small-scale mining has poisoned rivers, destroyed land, and broken communities. More than 150 students from across Grounds came forward to solve this real-world health problem in the annual Global Health Case Competition held by the Center for Global Health Equity (CGHE). The case – water pollution in Ghana, is a major environmental health problem, impacting communities across the world.
