Sungai dan Danau Terkotor di Dunia

#1.Lake Victoria

Lake Victoria borders three countries in East Africa – Kenya, Tanzania and Uganda – making it extra difficult to negotiate cleanup and pollution prevention. As there are few enforced regulations, residents wash cars in the same lake water that sewage water is regularly released in and that they also end up bathing in. Even worse, people who come in contact with the water are susceptible to coming away with several diseases including, schistosomiasis, bilharzia, cholera, pneumonia, diarrhea, and several skin diseases.

#2. Citarum River

The 200-mile long Citarum River in Indonesia hosts more than 500 factories along its banks and is quite possibly the most polluted river in the world. There is so much garbage coating the surface that in many places you can’t see the water, and it is more profitable to forage for garbage than making a living fishing the river, though you do risk catching a nasty disease by spending any time in it.

#3. The Great Lakes

The Great Lakes (US/Canada) have taken a beating over the years thanks to pollution from the auto industry, oil refineries, steel plants, agricultural runoff and pollution, chemical plants and transportation runoff. While not the worst on this list, the lakes have accumulated a toxic soup that we have yet to deal with.

#4.Yellow River

This 3,400 mile-long Yellow River in China is frequently contaminated by chemical spills, and frequent diversions and damming, which causes the Yellow to often run dry and sometimes even turn red. 1/3 of the river is unusable, but this doesn’t seem to be slowing things down as the river is used to provide water for millions of people in China, whose expanding cities are another reason the river is contaminated.

#5.the Riachuela River

While small compared to the others on this list (only 65 miles), the Riachuela River, running through the heart of Buenos Aires, is referred to as the largest open pit toilet in the world, absorbing over 325,000 tons of sewage each day. Lead, mercury, cadmium, nitrates and copper all pollute this river and affect drinking water supplies for the over 5 million people living in the area.

#6. Lake Onondaga

Lake Onondaga (US) is so polluted it was designated a hazardous waste site by the US Environmental Protection Agency. Phosphorous, ammonia, nitrite, mercury, bacterial contaminants, from a long history of industrial activity in the area, along with non-point source pollutants, combine to make this lake one toxic soup.

#7.Sarno River

The Sarno River is regarded as the most polluted river in Italy and possibly all of Europe. Agricultural and sewage runoff frequently contaminates the river and treatment methods are inadequate to handle the pollution. The Sarno River frequently overflows its banks and therefore puts the local population at repeated risk for exposure.

#8.Lake Karachay

Believe it or not, Lake Karachay (Russia) is completely contaminated with radioactive (and other types of) waste, that was dumped into the lake from the Mayak Nuclear Waste Storage Facility, starting in the 1950’s. The waste is currently seeping out into area soils and rockbeds, threatening other rivers and even the Arctic. Scientists predict that if it makes it to the Arctic, it could spread around the world.

#9. Yumana River

The Yumana River may be the site of historic and holy rituals, but it’s also got its share of crap – literally. Over 3.5 billion litres of sewage pass through the river daily (making it over 100,000 times higher than limits safe for bathing), and the city removes another 1.1 billion litres of river water each day. No fish or plants can live in the river and holy leaders have threatened to boycott annual pilgrimages to the area due to the high contamination levels.
