The Himalayan region, covering India, Nepal, Bhutan, China, Pakistan, and Afghanistan, is facing a growing problem with e-waste messing up its clean water bodies, thanks to more waste and not enough ways to handle it. In 2022, the world made 62 million tonnes of e-waste, but only 25% was recycled properly, letting dangerous stuff like lead and mercury leak into the environment. This chapter looks at where e-waste comes from in Himalayan rivers, like from tourists and small recycling shops, and how it harms water quality—levels of heavy metals often go past safe limits, hurting fish, plants, and even causing brain problems for people. It also points out big challenges, like weak rules, few recycling centers, and not enough good data, while suggesting easy fixes like better trash collection, proper recycling spots, teaching people about the issue, tougher laws, and using nature-friendly cleanup methods. The chapter calls for everyone to team up fast and track data better to keep the Himalayas’ important water safe for the future.
