The Luni River, which flows through the Thar Desert in Northwest India, has been facing severe pollution issues in recent years. Once a vital source of drinking water and irrigation for the Marwar region of Rajasthan, the river now battles contamination that threatens the health and livelihood of the local communities. The primary source of pollution in the Luni River is the discharge of hazardous pollutants by the textile and dyeing industries located along its banks, particularly in Balotra, Bithuja, Jasol, and Pali. These industries release untreated or partially treated chemical effluents into the river, leading to the degradation of water quality and the loss of its natural flow. The pollution has also impacted groundwater sources and agricultural lands, rendering them infertile and unsuitable for cultivation. Despite legal interventions and efforts by organizations like the 'Pradushan Niwaran and Paryavarn Sanrakshan Samiti', the challenge of addressing the pollution in the Luni River persists due to non-compliance by some industries with environmental standards and the continued discharge of pollutants.

Pollution from textile industries
The Luni River, also known as the Sagarmati, Maruganga, and Lavanavari or Lavanavati, is a significant water source in the Thar Desert in Northwest India. It originates in the Aravalli Range near Ajmer and flows southwest through Rajasthan, covering a catchment area of approximately 37,363 square kilometers. The river provides irrigation and drinking water to the inhabitants of the Marwar region, playing a vital role in agriculture and supporting the production of various crops.
However, in recent times, the Luni River has been facing a significant challenge due to pollution from various sources, with the primary culprit being the textile industry. The river has become highly polluted due to the discharge of hazardous chemicals and untreated effluents from textile dyeing and printing units located along its banks. This pollution has severely impacted the river's water quality, making it unfit for irrigation and dangerous for drinking.
The city of Balotra, situated on the bank of the Luni River, is a hub for cotton and synthetic dyeing, printing, and textile industries. These industries discharge hundreds of millions of liters of effluent per day into the river. The result is severely polluted water that contaminates not only the river itself but also the groundwater and surface water bodies in the surrounding areas. This contamination has rendered hundreds of hectares of agricultural land barren and unsuitable for cultivation.
The problem is exacerbated by the fact that the polluted river water seeps into the ground, further contaminating the groundwater and adversely affecting soil quality. This has led to concerns about the very existence of the Luni River. Despite court orders and the efforts of voluntary organizations, some textile industries continue to discharge pollutants and fail to comply with environmental quality standards. The Rajasthan High Court and the National Green Tribunal (NGT) have played pivotal roles in addressing this issue, with the NGT declaring the Luni's water unfit for irrigation and ordering the shutdown of around 800 textile units for violating green norms.
The pollution from the textile industries has resulted in a loss of the river's natural flow, with freshwater turning into saline water as it reaches Balotra. This transformation is attributed to the high salt content in the soil in that region. The contamination has also affected the atmosphere in the surrounding areas, creating an intolerable environment due to the unmannered discharge of industrial wastes. The situation has negatively impacted the farmers and villagers who depend on the river for their livelihood and well-being.

Printing and dyeing units
The Luni River, which runs through the Thar Desert in Northwest India, has been facing severe pollution issues in recent years. The primary source of this pollution has been attributed to the discharge of hazardous pollutants by the printing and dyeing industry located along its banks. The city of Balotra, situated on the bank of the Luni River, is a hub for cotton and synthetic dyeing and printing. These dyeing and printing units release hundreds of millions of liters of effluent into the river daily.
The impact of this industrial pollution has been devastating for the environment and local communities. The water in the Luni River and the groundwater in the surrounding areas have become highly polluted, rendering it unfit for drinking or irrigation. The once fertile lands are now barren, and the atmosphere in the surrounding areas has deteriorated due to the uncontrolled discharge of industrial wastes. Hundreds of hectares of agricultural land have been rendered useless due to hazardous chemicals, adversely affecting the livelihood of farmers and the health of the villagers.
The pollution from these printing and dyeing units has not only affected the Luni River but also the Bandi River, a tributary of the Luni. The chemical effluents released by these units into the Bandi River eventually merge with the Luni, further adding to the pollution. This has resulted in the loss of the Luni River's natural flow, with freshwater turning into saline water as it reaches Balotra. The high salt content in the soil impacts the river, and the river's existence is now under threat.
Despite efforts by the National Green Tribunal (NGT) and the Rajasthan High Court to address this issue, the pollution persists. The NGT declared the Luni water unfit for irrigation and ordered the shutdown of around 800 textile units for violating green norms. However, the industries ignored the court's orders, and even after assurances of compliance, they continue to discharge pollutants. The lack of full compliance with environmental quality standards and the failure to achieve zero liquid discharge (ZLD) remain significant concerns.
The 'Pradushan Niwaran and Paryavarn Sanrakshan Samiti', a voluntary organization, has been actively fighting against river pollution and advocating for the enforcement of green norms, raising awareness, and seeking compensation for farmers who have suffered crop damage due to contaminated water. Their efforts have been instrumental in combating the pollution of the Luni River and ensuring the rights and well-being of the affected communities.

Non-compliance with environmental standards
The Luni River, also known as the Sagarmati, Maruganga, and Lavanavari or Lavanavati, is a significant water source for the Thar Desert in Northwest India. Originating in the Aravalli Range, the river covers a catchment area of approximately 37,363 square kilometres and traverses a total distance of about 500 kilometres before dissipating into the Rann of Kutch.
Once a lifeline for the Marwar region of Rajasthan, providing drinking water and supporting agriculture, the Luni River now faces severe pollution issues. The main source of pollution has been identified as the discharge of hazardous pollutants by the printing and dyeing industries located along its banks, particularly in Balotra, Bithuja, Jasol, and Pali. These industries release hundreds of millions of litres of untreated or partially treated effluent into the river daily, contaminating both the river water and the groundwater in surrounding areas.
Despite interventions by the National Green Tribunal (NGT) and the Rajasthan High Court, non-compliance with environmental standards persists. In response to a public interest litigation, the NGT declared the Luni River's water unfit for irrigation due to pollution. Subsequently, the court ordered the shutdown of around 800 textile units for violating green norms. However, challenges remain, as some industries continue to discharge pollutants and fail to achieve zero liquid discharge (ZLD).
The lack of full adherence to environmental quality standards by certain industries is a significant concern. Despite court orders, some textile industries have been accused of disregarding green norms and continuing to release hazardous pollutants into the river. This non-compliance has resulted in the degradation of water quality, adversely impacting the river ecosystem, groundwater sources, and the health and livelihood of the local communities.
The contaminated water in the Luni River has spoiled drinking water sources and rendered fertile lands barren. The pollution has also affected fish diversity, with invasive species such as the African Catfish and Mozambique tilapia reported in the river. The failure to comply with environmental standards has had far-reaching consequences, and continued non-compliance will likely result in further ecological damage and increased health risks for the surrounding populations.

Impact on drinking water and agriculture
The Luni River, which flows through Rajasthan in India, has been a source of drinking water for the inhabitants of the Marwar region. However, the river's water quality has degraded due to the discharge of hazardous pollutants, primarily by the textile and dyeing industries located along its banks. This has had a significant impact on both drinking water sources and agricultural practices in the region.
The river water, once considered freshwater, becomes contaminated with saline and toxic chemicals as it reaches Balotra, a town in the Barmer district. The natural flow of the river is disrupted, and the water becomes unfit for drinking and irrigation. The polluted water has spoiled drinking water in a large number of wells, with high levels of total dissolved solids (TDS) reported in the groundwater. The water is not only unsafe for consumption but also unsuitable for irrigating crops.
The impact of this pollution extends beyond the immediate vicinity of the river. The contaminated river water seeps into the ground, polluting groundwater and rendering large areas of farmland infertile. Wells in villages along the river, such as Rampura, Godo ka Wada, Mahesh Nagar Ajeet, and Bhanawas, have been affected, and the water is no longer suitable for drinking or agricultural purposes. This has caused significant worry among farmers, as their crops are suffering due to a lack of clean irrigation water.
The pollution in the Luni River has also led to a decline in soil quality, further exacerbating the challenges faced by farmers in the region. The land is turning barren and infertile, making it difficult to cultivate crops. The chemical effluents discharged by the textile industries are a major contributor to this issue, and despite court orders and interventions, some industries continue to violate environmental norms and discharge untreated water into the river.
The impact on agriculture is not limited to crop damage but also includes the contamination of agricultural produce. The hazardous chemicals present in the river water can be absorbed by plants, potentially rendering them unsafe for consumption. This poses risks not only to the environment but also to human health, as consuming contaminated produce can have adverse effects.
To conclude, the pollution in the Luni River has had a significant impact on drinking water sources and agricultural practices in the region. It has spoiled drinking water, rendered land infertile, and contaminated crops. Efforts to combat this pollution and seek compensation for affected farmers have been led by organisations like the Pradushan Niwaran and Paryavarn Sanrakshan Samiti. However, ensuring the effective enforcement of environmental standards and achieving zero liquid discharge remain ongoing challenges.

Efforts to combat pollution
The National Green Tribunal (NGT) and the Rajasthan High Court have also played pivotal roles in addressing the Luni River's pollution problem. In response to a public interest litigation, the NGT declared the Luni's water unfit for irrigation due to pollution from textile dyeing units. The court ordered the shutdown of around 800 textile units for violating green norms, and subsequent assessments were conducted to monitor the situation.
Despite these legal interventions and the efforts of various stakeholders, challenges persist. Some textile industries continue to discharge pollutants into the river, and encroachments in the catchment area remain a concern. The lack of full compliance with environmental quality standards and the failure to achieve zero liquid discharge (ZLD) are issues that need to be addressed.
Local authorities have announced the removal of encroachments, but political pressure has hindered their effectiveness. Activists have called for the government to take serious note of these encroachments and stop the discharge of dangerous pollutants. The persistence of these issues underscores the need for continued and intensified efforts to combat pollution in the Luni River and protect the health and livelihoods of those who depend on it.
