Case Study: Aconcagua River in Chile - the polluted drinking water supplier
The Aconcagua River is about 142 kilometers long and runs through five Chilean provinces, supporting a number of cities along its way. Agriculture, mining, and chemical production are the most important economic activities in the area. About 30% of Chilean grapes and peaches, as well as a good part of Chilean avocado are produced in the Aconcagua river basin. These activities inevitably result in pollution by heavy metals and pesticides, but also micropollutants from households and wastewater treatment plants are emitted into the river.
