Toxic foam plagues Tamil Nadu dam as farmers seek urgent intervention

Kelavarapalli Dam continues to grapple with persistent toxic foam pollution, raising alarm among farming communities dependent on its waters for irrigation and daily needs. The dam, which receives water from Karnataka during the monsoon season, has become a source of tension between local stakeholders and authorities over the quality of water resources shared across state boundaries.

Farmers in the region allege that sewage discharge from upstream areas in Karnataka is the primary cause of the recurring foam and contamination. The polluted water has direct implications for agricultural activities, livestock rearing, and the health of surrounding communities reliant on the dam for domestic and irrigation purposes.

Despite mounting pressure from residents and repeated appeals to authorities, the issue remains largely unresolved. Local farming groups have called for decisive intervention from the Water Resources Department and the Tamil Nadu Government, seeking both immediate remedial measures and long-term solutions to prevent further ecological and economic damage.

The situation underscores ongoing challenges in inter-state water management and environmental protection along shared water bodies in South India. Authorities have yet to announce concrete steps to address farmers' grievances or enforce stricter pollution controls upstream.
