The Citarum River, the longest and largest 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 river into a toxic swamp. The primary sources of pollution are the 1,900 to 2,800 industrial facilities, mostly from the textile industry, located along the riverbed, which dump around 20,000 to 280 tons of toxins and untreated wastewater into the river daily. In addition, household waste and agricultural runoff also contribute significantly to the pollution of the river. The pollution has had severe environmental and health impacts, including the elimination of a significant part of the river's fish population and various skin diseases and respiratory issues among the locals.

What You'll Learn
Industrial waste
The Citarum River in West Java, Indonesia, is considered the world's most polluted river. The river is crucial for local livelihoods, providing water for drinking, washing, and irrigating rice fields. However, it has been contaminated by various sources, including industrial waste from the approximately 2,000 factories located along its banks. These factories, predominantly from the textile industry, discharge enormous amounts of chemical waste directly into the river.
The textile factories in Bandung and Cimahi are significant contributors to toxic waste. They release over 20,000 tons of waste and 340,000 tons of wastewater into the river daily, containing toxins such as lead, mercury, arsenic, sulphites, nonylphenol, and phthalates. The Indonesian government, pressured by organisations like Greenpeace, has initiated a seven-year cleaning program, aiming to make the river water drinkable by 2025.
The high levels of toxins in the river have resulted in a 60% decline in the number of fish species since 2008. Additionally, people living along the river suffer from various health issues due to exposure to contaminated water. These health issues include tuberculosis, chronic bronchitis, dermatitis, and other skin problems. The water is also used to irrigate rice fields, leading to reduced rice yields and potentially contaminating the crop with chemicals.
The Indonesian military has taken charge of the river's clean-up, and they now have the authority to block outlets conveying polluted wastewater from factories into the river. They are also installing rubbish and water treatment facilities. However, challenges remain, including limited resources for water purification, lack of coordination, and upstream soil erosion.
The Citarum River's pollution by industrial waste has severe environmental and health consequences, and the ongoing efforts aim to restore the river's health and provide safe water for the communities dependent on it.

Household waste
The Citarum River, located in West Java, Indonesia, is considered the world's most polluted river. The river is heavily polluted by human activity, with about five million people living in its basin. The pollution in the Citarum river basin has two main causes: the conflict in water usage and the lack of enforcement and regulation.
One of the main sources of pollution in the Citarum River is household waste. Residents along the river basins often lack the funds to install proper sewage systems or water treatment facilities. The government also fails to provide recycling facilities, leading to garbage ending up in the river. Household waste, including degradable and non-biodegradable rubbish, is often stored along the banks of the river. These trash piles can grow too large and spill over into the river, further polluting the water with physical waste.
The poorest individuals living along the Citarum scavenge for plastics and other recyclable materials to sell in exchange for groceries, mobile phone credit, or discounts on their energy payments. When the rubbish is not disposed of near the river, it is burned in large fires, releasing toxic fumes that have been linked to increased cases of tuberculosis and bronchitis in the local community.
The lack of access to proper waste disposal and treatment systems highlights the need for government intervention and the development of sustainable waste management solutions in the area. It is crucial to address the issue of household waste to improve the water quality and reduce the environmental and health impacts of pollution in the Citarum River basin.
In addition to household waste, the Citarum River also faces pollution from industrial waste, agricultural runoff, and bacterial contamination. The river is used as a natural sewage system, with a significant amount of human and animal waste being dumped into it daily. The high levels of faecal coliform bacteria pose a serious health risk to the locals who rely on the river as their primary source of water.

Sewage
The Citarum River, located in West Java, Indonesia, is considered the world's most polluted river. The river is heavily polluted by human activity, with about five million people living in its basin. The primary sources of pollution are the approximately 2,000 industrial facilities, mostly from the textile industry, located along the riverbed. These factories discharge enormous amounts of chemical waste and untreated textile runoff directly into the river. The wastewater from these factories contains a cocktail of toxic and hazardous chemicals, including heavy metals such as lead, mercury, iron, cadmium, chromium, cobalt, and manganese.
In addition to industrial waste, sewage waste is also a significant contributor to the pollution of the Citarum River. The river is used as a natural sewage system, with an estimated 35.5 tonnes of human waste and 65 tonnes of livestock waste dumped into the river each day. The high levels of faecal coliform bacteria in the river pose a serious health risk to the locals who rely on the river as their primary source of water. The water from the river and surrounding villages, used for washing, drinking, and cooking, can range from yellow to black in colour and is often contaminated with heavy metals and microplastics.
The pollution in the Citarum River has had severe environmental and health impacts. The river's fish population has decreased by 60% since 2008, and the water quality is so poor that fishing is no longer a viable source of income for those living along the river. The pollution has also affected agriculture, with rice yields dropping and crops damaged by the poor water quality. Those who rely on the river for their livelihood, such as farmers and fishermen, have suffered economic consequences due to the pollution.
The Indonesian government, after pressure from international organisations and activists, has recognised the severity of the problem and implemented a seven-year cleaning programme for the Citarum River, with the goal of making its water drinkable by 2025. The programme includes reforestation efforts, extraction of toxic sediment, and the prohibition of factories from discharging wastewater until it has been properly treated. While there is hope for the rehabilitation of the river, the success of these efforts will depend on effective enforcement and the cooperation of the various culprits contributing to the pollution.

Toxins and heavy metals
The Citarum River in West Java, 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 toxins and heavy metals.
The river stretches for 300 kilometres and is the longest and largest river in West Java. It is the third-longest river in Java, after Bengawan Solo and Brantas. The Citarum plays an important role in the lives of the people of West Java, providing a crucial water supply for drinking, irrigation, and industrial processes.
The primary sources of pollution in the Citarum River are the approximately 2,000 industrial facilities located along its banks, mainly from the textile industry. These factories dump around 280 tonnes of toxins into the river daily, including lead, mercury, iron, cadmium, chromium, cobalt, manganese, and arsenic. High levels of these heavy metals have been detected in the river, with lead levels reported to be 1,000 times above the US Environmental Protection Agency standard for drinking water. Other toxins found in the river include sulphites, nonylphenol, phthalates, PCB 180, paranitrophenol, and tributylphosphate.
The impact of this pollution has been devastating for the environment and local communities. The number of fish species in the river has decreased by 60% since 2008, and those who rely on fishing as a source of income have lost their livelihood. The pollution has also affected agriculture, with rice yields dropping due to irrigation with contaminated water. Local residents who depend on the river for their water supply have experienced various health issues, including skin diseases, respiratory problems, and increased rates of tuberculosis and bronchitis.
Efforts to clean up the Citarum River have been initiated, including a seven-year cleaning programme launched by the Indonesian government in 2018, with the goal of making the river water safe for drinking by 2025. The programme includes reforestation, extraction of toxic sediment, prohibition of wastewater discharge without filtration, and environmental education projects. However, challenges remain, including enforcement of regulations and the involvement of multiple culprits in the pollution.

Lack of enforcement and regulation
The Citarum River in West Java, Indonesia, is considered the world's most polluted river. It is the third-longest river in Java and plays a crucial role in the lives of the people in the region. However, despite its importance, the Citarum has suffered from severe pollution due to a lack of enforcement and regulation.
The river has been heavily polluted by various sources, including industrial waste and household waste. There are about 2,000 industrial facilities, mostly from the textile industry, located along the riverbed. These factories discharge enormous amounts of chemical waste and untreated textile runoff into the river. The wastewater from these factories contains toxic heavy metals, such as lead, mercury, iron, cadmium, chromium, cobalt, and manganese, which have severe health impacts on the local population. Despite laws requiring factories to treat their wastewater before releasing it into the river, enforcement has been minimal. Activist groups have reported widespread false reporting and bribery, allowing these facilities to continue polluting the river.
In addition to industrial waste, household waste also contributes significantly to the pollution of the Citarum River. The residents along the river basins often lack the funds to install proper sewage systems or water treatment facilities. As a result, human and animal waste, as well as household sewage and plastic waste, end up in the river. The government's failure to provide recycling facilities further exacerbates the problem, as garbage is often burned or dumped into the river.
The lack of enforcement and regulation has led to severe consequences. The river's fish population has decreased by 60% since 2008, and those living along the river suffer from various health issues, including skin diseases, respiratory problems, and increased rates of tuberculosis and bronchitis. The pollution has also affected agriculture, with rice yields dropping and crops damaged due to contaminated water.
Efforts have been made to clean up the Citarum River, including a seven-year cleansing program initiated by President Joko "Jokowi" Widodo in 2018, with the goal of making the river's water drinkable by 2025. The program involves the Indonesian Army, the Coordinating Ministry for Maritime Affairs, and support from the International Monetary Fund and the Asian Development Bank. However, for these efforts to succeed, it is crucial that the government takes strong action against rogue businessmen who continue to dump industrial wastewater into the river and enforces regulations to prevent further pollution.
