The most polluted rivers in the world include the Ganges River, Yellow River, Citarium River, Buriganga River, Sarno River, and many more.

Rivers are a vital part of our environment. They house millions of precious species in addition to providing billions of people with clean drinking water. On the other hand, worldwide river pollution is on a rise. In fact, it is one of the top environmental challenges. The discharge of agricultural, municipal, and industrial pollutants, is seriously damaging river ecosystems and threatening the supply of clean drinking water. And that’s not all! Even more serious consequences arise from dirty rivers entering the ocean.

Here are the top 25 most polluted rivers in the world.

1. Ganges River, India
