3. United States of America
The US has had its fair share of water pollution disasters. That’s why it’s on our list of most water polluted countries with the worst pollution in the world. To name a few major ones out of: The Deepwater Horizon oil spill in 2010 that released 5 million barrels of oil into the sea and killed 11 people, the Elk River chemical spill in 2014 that injured more than 150 people, the wastewater spill from Gold King Mine that turned the Animas River yellow, and the 1993 disease outbreak in Milwaukee caused by parasites that entered water treatment plants and caused many illnesses including more than a hundred deaths.
