Industrial pollution suspected as Cauvery river turns green in Tamil Nadu

Sections of the Cauvery river in Erode district have developed a distinctive green hue, triggering alarm among local communities who suspect industrial pollution as the likely cause. The unusual discoloration has been observed across multiple parts of the district, raising concerns about water quality and potential environmental hazards.

Local residents have appealed to the Tamil Nadu Pollution Control Board (TNPCB) to conduct urgent inspections of the affected stretches and collect comprehensive water samples for analysis. The action is aimed at determining the nature and source of contamination affecting one of South India's major river systems.

The Cauvery river, which supplies water for agricultural, industrial and domestic use across Tamil Nadu and Karnataka, has been subject to periodic pollution incidents. Erode district, a major textile and industrial hub, has witnessed recurring water quality concerns linked to discharge from manufacturing units.

Authorities have been called upon to expedite their investigation and identify polluting sources to prevent further deterioration of water quality and protect public health in the region.
