A significant layer of toxic foam was once again seen floating on the surface of the Yamuna River in Delhi, leading authorities to launch an immediate cleanup operation. The recurring formation of this thick, white foam has become a major environmental concern in the national capital, especially during periods of reduced water flow. Environmentalists and citizens have raised questions regarding the persistent pollution levels in the river, which remains highly contaminated despite several restoration initiatives.
According to officials, the foam is primarily the result of untreated industrial effluents, detergents, sewage discharge, and chemical waste entering the river from both authorised and unauthorised drains. When the flow of the river decreases, these pollutants accumulate and react, leading to the formation of foam. The situation worsens during winter months when the water temperature drops and the flow becomes sluggish, allowing chemical concentrations to rise.
Teams from the Delhi Jal Board, Irrigation and Flood Control Department, and other civic agencies began cleaning operations early Monday morning. Workers deployed boats, nets, and temporary floating barriers to control the spread of the foam. The foam was collected manually and pumped into containers for disposal. Officials stated that the process would continue throughout the week, depending on the weather and water conditions.
The Delhi government also highlighted that several drains carrying untreated sewage from residential and industrial areas contribute heavily to the pollution load in the Yamuna. Despite ongoing projects under various river rejuvenation schemes, full treatment of wastewater remains a challenge. The government reiterated its commitment to expanding sewage treatment capacity and strengthening monitoring of industrial waste discharge.
Residents living near the river expressed concerns about the strong odour and health risks posed by the toxic foam. Experts have warned that direct contact with the foam can cause skin irritation, breathing difficulties, and other health problems due to its chemical content. Fishermen and people who use river water for daily activities have been advised to avoid entering the water until the foam clears.
Environmental activists pointed out that the emergence of foam every year indicates deeper systemic issues in waste management and pollution control. They urged both the state and central governments to coordinate efforts more effectively to ensure long-term solutions rather than temporary cleanups.
Meanwhile, the Central Pollution Control Board has intensified monitoring at key points along the river to measure chemical and biological oxygen demand levels. Preliminary reports suggest a spike in pollutants, confirming that the recent foam is linked to high detergent and waste concentrations.
Authorities assured that cleanup work will continue until the river surface becomes clear. They also announced stricter action against industries found violating waste disposal rules. Long-term plans include upgrading sewage treatment plants, improving drainage systems, and increasing penalties for pollution.
As Delhi continues to battle its recurring pollution challenges, the latest incident underscores the urgent need for consistent environmental management and strengthened enforcement to restore the health of the Yamuna River.
