The Medellín River flows through the city of Medellín and its metropolitan area in Colombia. It begins high in the mountains and runs 98 km through 10 municipalities before joining the Porce River. The Medellín River was once clean but became contaminated over time due to wastewater and industrial pollution from the growing city. The document discusses the pollution problems of the Medellín River and proposes that citizens work together to implement new ideas to clean the river in the future.
