The Citarum River is the third-largest river in Java, Indonesia, and is relied upon by millions
The Citarum River, also known as the Tarum River, is the third-largest river in Java, Indonesia. It is the longest river in West Java and is relied upon by millions of people. The river stretches for 300 kilometres and is crucial for local livelihoods. However, it has also been dubbed the "world's dirtiest river" by the World Bank due to decades of pollution and neglect.
The Citarum River basin covers an area of 6,929 square kilometres, and around 25 million people live within it. The river provides water for drinking, cooking, washing, and irrigation for agriculture. It is also used for fishing, although the fish population has decreased by an estimated 60% since 2008 due to pollution.
The primary source of pollution in the Citarum River is the approximately 2,000 industrial facilities located along its banks, mainly from the textile industry. These factories discharge enormous amounts of chemical and toxic waste directly into the river, including lead, mercury, arsenic, cadmium, cobalt, and other toxins. In addition, about 20,000 tons of waste and 340,000 tons of wastewater are disposed of into the river daily. As a result, the water has become severely polluted, with high levels of lead, aluminium, manganese, iron, and other heavy metals.
The pollution in the Citarum River has had significant negative impacts on the environment and the local communities. The water quality is so poor that it does not meet the government's water quality standards, and people who depend on the river for their water supply often suffer from various skin diseases and respiratory problems. Agriculture has also been affected, with rice yields dropping and crops damaged due to polluted water.
Efforts have been made to clean up the Citarum River and improve water quality. In 2018, the Indonesian government, with support from international organisations, launched a seven-year cleaning programme with the goal of making the river's water drinkable by 2025. The programme includes reforestation, extraction of toxic sediment, and setting up waste treatment facilities. It is estimated that reforestation will require the planting of 125 million trees in the vicinity of the river. While there is hope for the revival of the Citarum River, consistent and effective implementation of measures is essential to ensure the success of the cleaning efforts.

The river is polluted with human and animal waste, industrial toxins, and agricultural runoff
The Citarum River in West Java, Indonesia, is considered one of the most polluted rivers in the world. The river is heavily polluted by human and animal waste, industrial toxins, and agricultural runoff.
Human and Animal Waste
The Citarum River serves as a natural sewage system for the millions of people living along its banks. Limited access to proper sewage systems and water treatment facilities results in human waste being dumped directly into the river. According to estimates, 35.5 tonnes of human waste are released into the river each day.
Additionally, the river receives a significant amount of animal waste. Livestock waste, particularly from the many animals living and grazing along the river, contributes about 65 tonnes of waste to the river daily.
Industrial Toxins
The river is also heavily impacted by industrial pollution. Along the 300-kilometre stretch of the river are approximately 2,000 industrial facilities, with many belonging to the textile industry. These factories discharge chemical and toxic waste directly into the river, including lead, mercury, arsenic, cadmium, cobalt, and other toxins. It is estimated that these industries release 280 tonnes of toxins into the river daily, severely affecting water quality.
Agricultural Runoff
Agricultural practices also contribute to the pollution in the Citarum River. Excessive use of pesticides and fertilisers by farmers can leech into the river, adding toxic chemicals to the water. Additionally, agricultural runoff from fields and villages, including detergents and other pollutants, further contaminates the river.
The pollution in the Citarum River has had devastating consequences on the environment and the health of the people who rely on it. Fish populations have declined, and those who depend on the river for their livelihood, like fishermen, have been forced to find alternative sources of income. The water is no longer safe for human consumption, leading to various health issues, including skin diseases and respiratory problems.
Efforts are being made to clean up the river and restore it to a healthy state. The Indonesian government has launched a seven-year cleaning programme, and international organisations like the World Bank and the Asian Development Bank have committed funds to support the rehabilitation process.

This pollution has led to skin diseases, respiratory issues, and other health problems for those who rely on the river
The Citarum River in West Java, Indonesia, is considered one of the most polluted rivers in the world. Decades of neglect and mismanagement have turned the once-pristine waterway into a toxic swamp. The river is heavily polluted by human activity, with about 5 million people living in its basin and relying on it for their daily needs.
The pollution in the Citarum River has led to various health problems for those who rely on it. The water is contaminated with high levels of lead, mercury, iron, cadmium, chromium, cobalt, manganese, and other toxins. Lead levels in the river have been found to be 1,000 times above the US Environmental Protection Agency's standard for drinking water. As a result, people living along the river have developed skin diseases, ranging from scabies to infections. The water is also believed to be a contributing factor to the high rates of tuberculosis and bronchitis in the area, with toxins from burning waste and factory smoke causing respiratory distress.
In addition to respiratory issues, the ingestion of contaminants through food and water has led to other health problems. Rice, a staple food for many communities, is irrigated with polluted water, lacing the crop with chemicals. People living along the river have reported skin problems and other illnesses due to the consumption of contaminated water and food. The water from the river and wells can range from yellow to black in colour, with detergents causing foam, and is unsuitable for drinking, cooking, or washing.
The impact of the pollution on the river ecosystem has also affected the health of those living in the area. Fishing was once a source of livelihood for some, but the river's fish population has decreased by an estimated 60% since 2008 due to pollution. The remaining catch is contaminated with heavy metals and microplastics, further posing health risks to those who consume it.
The Indonesian government has recognised the severity of the issue and initiated a seven-year cleaning programme in 2018, aiming to make the river's water drinkable by 2025. The programme includes reforestation, extraction of toxic sediment, prohibiting factories from discharging wastewater, and environmental education projects. However, the success of these efforts remains to be seen, and the health of those relying on the river continues to be at risk until significant improvements are made.

There have been multiple attempts to clean up the river, including a seven-year plan initiated by the Indonesian government
The Citarum River in Indonesia is considered one of the most polluted rivers in the world. It is relied upon by millions of people, but decades of pollution have contaminated it with chemicals and rubbish. The river is heavily polluted by human activity, with about five million people living in its basin. The drainage area covers 6,929 square kilometres and is home to more than 2,000 industries, including textile factories that discharge chemical waste directly into the river.
In addition to the government's seven-year plan, other organizations have also contributed to the river's cleanup. Monash University has collaborated with local communities, academics, and the Indonesian government to create a transdisciplinary approach to river transformation. The United Nations Development Programme (UNDP) has also conducted training for companies operating along the river to adopt responsible business practices that protect human rights and the environment.
The cleanup efforts have shown some positive results. According to a village leader, Bapak Cece, people can now go fishing and swimming in the river, especially when it rains. Recycling and education projects have also sprung up across the region, with central and local authorities partnering with communities to promote the economic and health benefits of a clean Citarum River.
However, despite these efforts, challenges remain. There is a lack of coordination at the local level, bribes paid by factories to avoid change, and upstream soil erosion from deforestation. Additionally, without immediate action against rogue businessmen who create dumping holes for industrial wastewater, the river cleanup efforts may be in vain.

The success of these efforts depends on enforcing regulations, providing treatment facilities, and addressing the sources of pollution
The Citarum River in West Java, Indonesia, is considered the world's most polluted river. Decades of neglect and pollution have turned the once pristine river into a toxic swamp. The river provides a crucial water supply for local livelihoods, but it is now contaminated with various pollutants, including heavy metals, toxins, and household and industrial waste. The success of the efforts to clean up the river and restore it to a healthy state depends on several critical factors:
Enforcing Regulations
The Indonesian government has established laws requiring factories to treat their wastewater before discharging it into the river. However, enforcement of these regulations has been minimal, with widespread false reporting and bribery allowing factories to continue dumping toxic chemicals into the Citarum. To address this, the government should increase monitoring and inspections of industrial facilities, impose strict penalties for non-compliance, and ensure transparency in reporting and waste management practices.
Providing Treatment Facilities
It is estimated that 90% of the nearly 2,000 industries located along the river do not have adequate waste treatment facilities. The government should invest in and provide access to advanced wastewater treatment technologies to ensure that industrial effluents are properly treated before release. Additionally, the government should support the development of recycling facilities to reduce the amount of household waste that ends up in the river.
Addressing the Sources of Pollution
The primary sources of pollution in the Citarum River are industrial waste and household waste. To address industrial pollution, the government should work closely with the textile and other industries to implement sustainable practices, revise guidelines to include more stringent parameters for waste management, and promote the use of environmentally friendly processes and materials. Regarding household waste, the government should provide financial assistance and infrastructure to communities along the river to implement proper sewage systems and waste management solutions, reducing the amount of garbage that ends up in the river or is burned, creating toxic fumes.
Reforestation and Soil Conservation
Soil erosion from upstream deforestation contributes to the silting of the lower river. Reforestation efforts, as suggested by the coordinator of the Citarum Sector 1 cleansing program, can help mitigate this issue. By planting a mix of hardwood plants and shrubs in the vicinity of the river, erosion can be reduced, and the river's natural flood mitigation capabilities can be restored.
Education and Awareness
Environmental education projects can play a vital role in empowering local communities to understand the impact of their actions on the river. Educating farmers about the safe and responsible use of pesticides and fertilisers can help reduce agricultural runoff and prevent further pollution of the river. Additionally, raising awareness about the health risks associated with using contaminated water for drinking, cooking, and washing can motivate individuals to demand change and adopt alternative sources of clean water.
The challenges facing the Citarum River are complex and interconnected. A comprehensive approach that addresses each of these factors is necessary to ensure the success of the river's revitalisation and the long-term health and sustainability of this vital waterway.
