Indonesia's Most Polluted River

101 East investigates the human cost of one of the world's most polluted rivers, the Citarum in Indonesia.

For generations, Indonesia's Citarum River has provided fish to eat, irrigation for rice fields, and fresh water for drinking, washing and cooking for the millions who live along its banks.

But today, it's known as the most polluted river in the world.

The river supplies water to textile factories that make clothes for some of the biggest fashion brands in the world - H&M, Gap, Uniqlo. It also provides an open sewer for the factories to dump toxic chemicals, thousands of litres at a time, creating an ecological disaster.
