Resolving Brahmaputra Pollution: Strategies For A Cleaner Future

The Brahmaputra River is suffering from severe water pollution, which is having a devastating impact on the environment and human health. Oil pollution and waste disposal are the two main causes of the river's degradation, which is being exacerbated by industrial and factory activity. This has led to an increase in waterborne diseases and is threatening the river's ecosystem. There is an urgent need to address this issue and find solutions to protect the river and the communities that depend on it.

Sewage pollution

One approach to tackling sewage pollution in the Brahmaputra River is to improve wastewater treatment infrastructure. This includes investing in advanced treatment technologies and ensuring that all wastewater is properly collected, treated, and discharged. Additionally, promoting sustainable sanitation practices, such as eco-friendly toilets and wastewater recycling, can help reduce the amount of sewage entering the river.

Another strategy is to enhance public awareness and community engagement. Educating local communities about the impacts of sewage pollution and promoting sustainable waste management practices can encourage behavioural changes. This includes proper waste disposal, reducing the use of harmful chemicals, and supporting river clean-up initiatives.

Furthermore, strict regulations and enforcement are crucial in combating sewage pollution. Governments and authorities should implement and enforce laws that prohibit the discharge of untreated sewage into the river. Regular monitoring and inspections of industrial and municipal wastewater treatment facilities can help ensure compliance with environmental standards.

To effectively manage sewage pollution, collaboration between different stakeholders is essential. Governments, industries, local communities, and non-governmental organizations should work together to develop and implement comprehensive sewage management plans. This includes investing in research and development to identify innovative solutions and best practices for sewage treatment and pollution prevention.

By addressing sewage pollution through a combination of improved infrastructure, public awareness, strict regulations, and collaborative efforts, it is possible to restore and protect the health of the Brahmaputra River. These measures will not only improve water quality but also safeguard the ecosystem and the well-being of the communities that depend on the river.

Microplastics

The Brahmaputra River is suffering from oil pollution and waste disposal issues. To resolve the problem of microplastics in the river, the following steps could be taken:

• Increase public awareness about the issue: Educate the public about the harmful effects of microplastics on the environment and human health. Encourage people to reduce their use of single-use plastics and dispose of waste properly.
• Implement stricter regulations: Governments should enforce stricter laws and regulations on industries and factories that are responsible for releasing microplastics into the river. This includes regular inspections and penalties for non-compliance.
• Improve waste management practices: Invest in improved waste management infrastructure and practices, such as recycling and proper disposal of plastic waste. This can help reduce the amount of microplastics that enter the river.
• Promote alternative materials: Encourage the use of alternative, biodegradable materials instead of plastics. This can help reduce the amount of microplastics that are produced and released into the environment.
• Monitor and research: Continue to monitor the levels of microplastics in the river and conduct research on the impact of microplastics on the environment and human health. This information can be used to inform policy decisions and develop effective strategies to reduce microplastic pollution.

Population growth

The growing population also means an increase in waste generation, including domestic and industrial effluents. Without proper waste management systems in place, these pollutants find their way into the river, degrading its water quality.

Additionally, population growth can lead to increased agricultural and industrial activities, which further contribute to the river's pollution. Pesticides, fertilisers, and other chemicals used in agriculture can wash into the river during rainfall or irrigation, adding to the toxic cocktail. Similarly, industrial discharges, if not properly treated, can release harmful substances into the river, affecting both the aquatic ecosystem and human health.

The impact of population growth on the Brahmaputra's pollution is evident in the river's deteriorating water quality over the years. Studies have shown a significant increase in water turbidity from 2006 to 2019, indicating heightened levels of suspended solids, often associated with human activities. This has caught the attention of the United Nations, which has raised concerns about the accelerated consequences of the river's pollution.

To address the pollution issue effectively, it is crucial to consider the impact of population growth and implement sustainable practices. This includes improving waste management systems, regulating industrial discharges, and promoting environmentally friendly agricultural practices. By addressing the root causes of pollution, we can work towards restoring the health of the Brahmaputra River and ensuring its long-term sustainability.

Water quality

The water quality of the Brahmaputra River has been assessed using Water Quality Indexes (WQIs). WQIs are used to assess water quality over a long period and inform decisions on water management policy in water scarcity conditions. A high WQI class means a low risk for the population that consumes the water. However, the official report on the water quality scenario of rivers emphasised the increase in water turbidity during 2006-2019, and the United Nations drew a signal of alarm on the accelerated consequences of the Brahmaputra River's pollution.

The water quality of the Brahmaputra River is affected by anthropogenic and environmental conditions. A study investigated the water parameters of the river recorded for 17 years at ten hydrological stations. When the hypothesis of a monotonic trend was rejected, a loess trend was fitted. The water quality was then assessed using three indicators: CCME WQI, British Colombia, and a weighted index.

To resolve the water pollution issue in the Brahmaputra River, it is essential to address the sources of pollution, such as oil spills and waste disposal. Regular checks and strict laws should be implemented to ensure that industries and factories have the necessary mechanisms in place to prevent oil spills from directly entering the river.

Disease prevention

The Brahmaputra River is suffering from severe water pollution, which is causing the spread of diseases. To prevent the spread of disease, it is essential to address the root causes of the pollution and implement effective solutions.

One of the primary sources of pollution in the Brahmaputra is oil spills. Oil pollution not only contaminates the river but also seeps into the groundwater, eventually finding its way into the river. To prevent oil spills from reaching the river, stricter laws and regulations must be enforced. The government should introduce and enforce strict laws to hold industries and factories accountable for oil spills, ensuring they have the necessary mechanisms in place to prevent and contain such incidents. Regular inspections of oil processing factories should be conducted to ensure compliance with environmental standards and to mitigate the risk of oil spills.

Another significant contributor to the pollution of the Brahmaputra is waste disposal. Improper waste disposal practices can lead to the contamination of the river and the spread of diseases. To address this issue, it is crucial to promote proper waste management practices and increase public awareness about the importance of responsible waste disposal. Educational campaigns can play a vital role in teaching individuals and communities about the proper methods for waste segregation, recycling, and disposal. Additionally, the government should invest in developing and improving waste management infrastructure, ensuring that waste is treated and disposed of safely and sustainably.

The quality of the water in the Brahmaputra River is also influenced by anthropogenic and environmental factors. To improve water quality and prevent the spread of diseases, it is essential to monitor and address these factors. Regular water quality assessments should be conducted using indicators such as the CCME WQI, British Colombia WQI, and weighted indexes. By analysing the data collected from these assessments, authorities can identify areas of concern and implement targeted interventions. This may include upgrading sewage treatment facilities, reducing industrial discharges, and restoring and protecting natural habitats that contribute to water filtration and purification.

Furthermore, the United Nations Environment Program has raised concerns about the accelerated consequences of the Brahmaputra River's pollution. WQIs (Water Quality Indexes) are valuable tools for assessing long-term water quality and guiding water management policies, especially in water scarcity conditions. While there is no mathematical formula to directly estimate the risk of water consumption based on WQIs, a high WQI class generally indicates a lower risk for the population consuming the water. By utilising WQIs and implementing evidence-based policies, decision-makers can help mitigate the health risks associated with polluted water and prevent the spread of waterborne diseases.
