7. Philippines
The Philippines is home to two of the most polluted rivers in the world, namely the Pasig River and the Marilao River, but that’s not it. 50 rivers in the country are considered dead, mostly because of the disaster that is the sewage system of this country. Most waste material from septic tanks drains into rivers without any treatment, leaving the population exposed and making Philippines one of the most water polluted countries with the worst pollution in the world.
