Citarum River

 

Around ninety percent (90%) of plastics in the ocean comes from just 12 rivers.

The top 12 most polluted rivers in the world have one thing in common – they are located alongside large human populations with poor waste management (PWM) systems.

Rivers drain the land carrying with the water-flow, man-made rubbish, to join the ocean currents where plastic waste and other litter is washed out to sea making it harder to track and collect. These plastic hot-spots would be prime targets for SeaVax machines operating in RiverVax mode.

Rivers are a logical target if we want to start cleaning up our oceans cost effectively. The following list is generally accepted to be the top twelve most polluted rivers in the world in 2015, but not necessarily the source of the most plastic:

1. Citarum River, Indonesia - The Citarum River is known as the most polluted river in the world and is located in West Java, Indonesia.

6. Jordan River, Israel - The Jordan River originates from the Anti-Lebanon and Mount Hermon mountain ranges covers a distance of 223 km. The river has severely deteriorated especially the lower reaches of Jordan are full of untreated sewage and contaminated water flowing from agricultural lands.

7. Yellow River, China - The Yellow River of China is drying up fast due to expansion of factories, cities, agricultural farms etc. and whatever water is left is contaminated badly. The water is so toxic that it is not fit for agriculture.

8. Marilao River, Philippines - The Marilao River flows through the Bulacan Province Philippines and empties in Manila Bay. The main sources for polluting this river are tanneries, textile factories, piggeries, gold refineries and municipal dumps.

9. Sarno River, Italy - The Sarno River is one of the most polluted rivers in Europe. It flows in southern Italy near Pompeii and Naples. In recent years many cases of liver cancer have been reported which shows the level of degradation of the river.

10. Mississippi River, USA - The Mississippi River in USA is also known as the ‘Big Muddy’ as the water of this river is usually brown because of pollution. Crude oil spills reported in the river which has made the water toxic and is poisonous to the marine life. The river is a sewer for farmers and industrialists making it one of the most polluted rivers in the world.

11. Cuyahoga River, USA - The Cuyahoga River flows through Cleveland, Ohio and is known for having caught fire many times. The river is completely choked with oil, sludge, sewage and debris.
