The National Aluminium Company Limited (NALCO), one of Asia’s largest integrated aluminum complexes, is located in the industrial town of Damanjodi, which is tucked away in the picturesque surroundings of the Koraput district in Odisha. The Poisonous Red Pond is a silent but dangerous environmental hazard that has surfaced amid industrial growth and commercial activity. The Poisonous Red Pond of Odisha poses a significant environmental threat due to its highly alkaline pH levels.
The Heart of the Issue
The Red Pond in Damanjodi is a striking and unsettling sight. Its vivid red hue stands out starkly against the green landscape, drawing attention to a deeper, more concerning problem: industrial pollution. The industrial processes carried out at the NALCO complex directly cause the pond’s color and toxicity, fueling economic growth while also leading to significant environmental degradation.
Origins of the Red Pond
The “Red Pond” in Odisha, also known as the Poisonous Red Pond, is located in Damanjodi, Koraput district. This pond is a byproduct of the alumina refinery operations of the National Aluminium Company (NALCO), one of Asia’s largest integrated aluminum complexes. The striking red color of the pond is due to the red mud, a highly alkaline waste product from the bauxite refining process.
The origins of this pond trace back to the establishment of NALCO’s refinery in the 1980s. The red mud contains various toxic elements, making the pond hazardous to the surrounding environment and local communities. Despite its dangerous nature, the pond is a significant part of the industrial landscape in Odisha, highlighting the environmental challenges associated with large-scale aluminum production.
Pond with pH Levels Over 13
The pH value of the Poisonous Red Pond in Damanjodi, Odisha, is typically very high, reflecting its strong alkalinity. This is due to the presence of red mud, a by-product of the alumina refining process, which contains a significant amount of caustic soda (sodium hydroxide) used during the extraction of alumina from bauxite ore. The pH of red mud slurry can range from 10 to 13 or even higher, indicating highly alkaline conditions.
Such a high pH level makes the water in the pond extremely toxic and corrosive, posing serious risks to the environment and any living organisms that come into contact with it. It can lead to severe ecological damage, including the destruction of aquatic life and the degradation of soil quality in surrounding areas.
Health and Environmental Impacts
The Poisonous Red Pond is not just an eyesore; it poses significant health and environmental risks:
- Human Health: The water in the pond is highly toxic and unsuitable for consumption or any domestic use. Residents in the vicinity have reported various health issues, including skin irritations and respiratory problems, due to direct or indirect contact with the contaminated water. Long-term exposure could potentially lead to more severe health conditions.
- Ecological Damage: The seepage of these contaminants into nearby rivers and groundwater can spread pollution, affecting broader ecosystems and making water sources unsafe for drinking and agriculture. The pond’s toxic waters have decimated local aquatic life. The high levels of heavy metals and caustic substances create a hostile environment for fish and other aquatic organisms, leading to a sharp decline in biodiversity. Additionally, the contaminants can leach into the soil, affecting the health of nearby vegetation and potentially entering the food chain.
Response and Remediation Efforts
Acknowledging the severity of the issue, both government authorities and NALCO have initiated efforts to address and mitigate the pollution:
- Regulatory Measures: Stricter regulations on industrial waste management have been implemented. NALCO is required to ensure proper disposal and treatment of industrial effluents to prevent further contamination of water bodies.
- Cleanup Initiatives: There are ongoing efforts to clean up the existing pollution. This includes treating the contaminated water to neutralize its toxicity and rehabilitating the affected ecosystems. Technologies such as constructed wetlands and bioremediation are being explored to cleanse the polluted water naturally.
- Community Awareness: Environmental activists and local community groups are working to raise awareness about the dangers of the Red Pond. Educational campaigns are being conducted to inform residents about safe practices and the importance of environmental conservation.
Looking Forward
The Poisonous Red Pond of Damanjodi serves as a critical reminder of the environmental costs of industrialization. While economic growth and industrial development are vital, they must be balanced with sustainable practices that protect and preserve the environment. The situation in Damanjodi underscores the need for stringent environmental regulations, responsible industrial practices, and proactive measures to address pollution.
The Struggle for Accountability
Efforts to hold NALCO accountable for the environmental devastation have been met with resistance and bureaucratic hurdles. Despite the efforts of local activists and environmental organizations, the company has not yet faced full responsibility for the damage it has inflicted on the region.
The fight for environmental justice in Damanjodi continues, as the community rallies to demand immediate action and long-term solutions to address the crisis. The fate of the poisonous red pond and the well-being of the surrounding ecosystem hang in the balance, a testament to the delicate balance between industrial progress and sustainable development.
As the world grapples with the mounting challenges of environmental degradation, the story of Damanjodi serves as a stark reminder of the urgent need to prioritize environmental protection and hold corporate entities accountable for their actions.

Frequently Asked Questions (FAQs)
The poisonous red pond is located in Damanjodi, a town in the Koraput district of Odisha, India.
The red color of the pond is due to the high concentration of iron oxides and other heavy metals in red mud, which is a waste product from the aluminum refining process. These substances give the water its distinctive red hue.
NALCO stands for National Aluminium Company Limited. It operates one of Asia’s largest integrated aluminum complexes in Damanjodi.
The primary pollutants in the Red Pond are iron oxides, heavy metals like aluminum and silica, and highly alkaline substances, particularly sodium hydroxide, which contribute to the pond’s toxicity.
The pH level of the Red Pond’s water is typically very high, often ranging from 10 to 13, indicating strong alkalinity. This makes the water highly toxic and corrosive.
The toxic water of the Red Pond can cause skin irritations and other health issues upon contact. Long-term exposure, especially if the contaminants enter groundwater, could lead to more serious health problems such as respiratory issues and heavy metal poisoning.
The pond’s toxic content severely damages the local ecosystem. It has led to the destruction of aquatic life and negatively impacts soil quality, reducing fertility and potentially contaminating nearby crops. The pollution can also spread to nearby water sources, affecting broader ecosystems.
