Stained waters: Silent cost of textile dyeing

As rivers are vital sources of water for millions of people, textile dye pollutants threaten both the environment and public health

Textile dyeing in India has become one of the major contributors to environmental pollution, particularly affecting the country’s rivers.

The process involves a vast quantity of water and chemicals, and often these chemicals are not properly treated before being discharged into the rivers. India’s textile industry, one of the largest in the world, relies heavily on water-intensive processes to dye fabrics, creating an enormous environmental burden.

These pollutants seep into the water, affecting the quality of the rivers and posing significant risks to aquatic life. The toxic nature of these substances disrupts ecosystems, harms fish populations, and reduces biodiversity. Furthermore, these chemicals find their way into the food chain, causing potential harm to humans who consume contaminated water or fish.

Rivers such as the Yamuna, Godavari, and Ganga are severely impacted by the untreated effluent that is released from dyeing units, often located near these water bodies.

In many cases, the textile factories simply discharge wastewater directly into the rivers without any form of treatment. The result is water that is not only visually polluted — stained in unnatural colours — but also chemically hazardous. It often becomes unfit for agricultural use, drinking, or even bathing.

As these rivers are vital sources of water for millions of people, this pollution threatens both the environment and public health.

The situation is exacerbated by the fact that, in many areas, there is insufficient regulation and enforcement to tackle the problem.

The scale of the industry’s impact on the water bodies of India reflects a broader, ongoing challenge in balancing industrial growth with environmental responsibility.
