China's Water Pollution Crisis: Regions In Dire Straits

Water pollution in China is a pressing issue, with half of the population lacking access to clean water. The coastal manufacturing belt and the coastal waters are among the worst-hit areas, with pollution soaring by more than 50% in 2012. The water quality in major cities like Shanghai and Beijing is also alarming, with high levels of pollution rendering water sources non-potable. The problem stems from the discharge of industrial and agricultural waste, with chemicals and hazardous pesticides endangering wells and underground water reserves. The Chinese government has acknowledged the issue, releasing the Action Plan for Prevention and Control of Water Pollution in 2015, but the impact of pollution on water scarcity remains a concern.

Waterways in China's coastal manufacturing belt are heavily polluted

Water pollution is a severe issue in China, with half of the country's population lacking access to safe drinking water. This problem is particularly acute in the coastal manufacturing belt, where industrial activities have heavily polluted waterways. Despite efforts to shut down thousands of polluting sources, such as paper mills and chemical factories, a third of the waterways in this region remain well below the government's modest standards for water quality.

The coastal waters of China have been suffering from "acute" pollution, with the extent of affected areas soaring by over 50% in 2012 compared to the previous year, according to a Chinese government body. This deterioration in water quality is attributed to land-based pollution, with sewage and industrial waste being discharged into the sea. One study revealed that eight out of ten Chinese coastal cities release excessive amounts of pollutants into the sea, often near coastal resorts and sea farming areas.

The pollution problem in China's coastal manufacturing belt is exacerbated by the lack of wastewater treatment systems in most rural areas. As a result, toxic human and industrial waste has contaminated China's water supply, leading to the proliferation of harmful algae blooms and rendering the water unfit for human consumption. This has had dire consequences for the health of the population, with high rates of cancer and other diseases being reported in villages located near polluted waterways.

The Chinese government has not been idle in the face of this crisis. In 2015, the Ministry of Environmental Protection ordered provinces to meet their water quality targets. Additionally, the government has started to appoint local party members as river chiefs, holding them accountable for the water quality in their jurisdictions. However, despite these efforts, nearly half of the country missed its water quality targets for the period 2011-2015, indicating the enormity of the challenge.

The pollution in China's coastal manufacturing belt is not an isolated issue. The country's rapid economic development and demand for cheap goods have contributed to weak environmental regulations and poor enforcement, allowing factories to discharge wastewater into lakes and rivers freely. As a result, all of China's lakes and rivers are polluted to some degree, with 70% seriously polluted and unfit for human consumption.

China's rural areas lack a system to treat wastewater

Water pollution in China is a severe issue, with half of the country's population lacking access to water that is safe for consumption. This problem is particularly acute in rural areas, where two-thirds of the population relies on tainted water sources. Most of China's rural regions lack a system to treat wastewater, and this is due to a multitude of factors.

Firstly, there is a lack of financial resources and initiatives to attract private capital investment in wastewater treatment systems (WTS) in rural areas. Local governments often struggle to finance the construction and operation of these systems, and the central government has historically provided limited subsidies for rural water supply and sanitation. The reliance on land rental income to fund wastewater treatment, as seen in Dala village, is not a sustainable financial model.

Secondly, the governance of WTS in rural areas is often inefficient. Village committees, which traditionally manage WTS, may lack the necessary expertise and motivation to effectively oversee these complex systems. The local leadership rotation system and limited participation from farmers can further hinder the smooth governance of WTS.

Thirdly, building suitable WTS across diverse geographic regions in rural China presents technical challenges. Decentralised, tailor-made WTS designs are more appropriate for the varying conditions in different areas, but these are rarely implemented.

The lack of an effective wastewater treatment system in China's rural areas has severe consequences, including health problems and environmental degradation. It is essential to address these challenges to improve access to clean water and protect the well-being of rural residents.

While China has made progress in recent decades, with increased municipal wastewater treatment and the creation of separate water and wastewater utilities, there is still much work to be done to ensure safe and sustainable water access in rural communities.

Cancer rates are high in villages near polluted water sources

China's rapid industrialization and scant pollution controls have led to high cancer rates in villages near polluted water sources. The country has a term for these communities: "cancer villages" (Áizhèng cūn). According to a Chinese government report, 70% of China's rivers, lakes, and waterways are seriously polluted, with 43% unsuitable for human contact. This has contaminated drinking water for 180 million people, leading to a surge in cancer cases.

In 2011, China's Ministry of Environmental Protection reported that 280 million Chinese people drank unsafe water. The coastal manufacturing belt, including eight out of ten coastal cities, discharges excessive sewage and pollutants into the sea, often near coastal resorts and sea farming areas. This has resulted in acute pollution of coastal waters, with the size of the affected areas increasing by more than 50% in 2012.

The problem is particularly severe in rural areas, where two-thirds of the population relies on tainted water. Most of these areas lack wastewater treatment systems, and groundwater in 90% of China's cities is contaminated. For example, in the village of Xinglong in Yunnan province, residents attribute their health issues, including an increase in cancer cases, to the nearby industrial park. Similarly, in Yanglingang, a village surrounded by chemical and pharmaceutical plants, deaths have risen above the national average, with residents claiming they live in a "cancer village."

While the Chinese government has made efforts to address water pollution, compliance remains an issue. In 2015, the Ministry of Environment ordered provinces to meet their water quality targets, but nearly half of the country missed these targets for the period 2011-2015. The lack of independent oversight by NGOs and journalists, coupled with the government's focus on urban development, has exacerbated the problem in rural "cancer villages."

Water pollution is worsening in China's major cities like Beijing and Shanghai

Water pollution is a significant issue in China, with half of the country's population lacking access to water that is safe for human consumption. This problem is particularly acute in major cities like Beijing and Shanghai, where industrialization and urbanization have led to increased pollution and strained water resources.

Beijing, the capital of China, faces severe water scarcity and pollution issues. The city experiences intense water scarcity during the long dry season and heavy flooding during the brief wet season. Two-thirds of Beijing's water supply comes from groundwater, which has been declining for decades due to overexploitation and recurrent droughts. The Yongding River, one of the main sources of drinking water for the city, had to be abandoned due to pollution. The Guanting Dam on the Yongding River, which used to provide drinking water, is now only used for irrigation and industrial purposes due to pollution. Another river, the Wenyu River, is heavily polluted as well. While there have been efforts to improve water quality and reduce pollution, the impact has been limited.

Shanghai, China's largest city, has also faced water pollution issues due to rapid industrialization and urbanization. Most of Shanghai's waterways are heavily polluted, and only 3% of the water in the city is clean enough for drinking or aquaculture. To meet the growing demand for freshwater, the city opened the Qingcaosha Reservoir on Changxing Island in 2010. The reservoir supplies about 70% of Shanghai's tap water and has significantly cleaner water than the Yangtze and Huangpu rivers. However, the reservoir still faces challenges with regular outbreaks of algae due to high levels of phosphorus and nitrogen in the Yangtze.

The water pollution in these cities has severe consequences for public health and the environment. According to a Chinese government report, 70% of China's rivers, lakes, and waterways are seriously polluted, with many unfit for human consumption. The pollution is also impacting wildlife, as seen in the decline of fish populations in affected waters.

To address the worsening water pollution in Beijing and Shanghai, various initiatives and infrastructure projects have been undertaken. In Shanghai, the municipal government has worked with the World Bank to implement the Shanghai Adaptable Program Loan (APL), focusing on long-term investments in water supply, wastewater, and solid waste systems. The Shanghai Sewage Project, launched in 1987, aimed to build water and wastewater infrastructure, leading to the establishment of the Shanghai Sewerage Company. Beijing has also implemented water-saving measures, such as recycling water for non-drinking purposes in new buildings and investing in water-saving renewables like wind, solar, and nuclear power.

Pollution from factories and farms is contaminating underground water reserves

Water pollution in China is a severe issue, with half of the country's population lacking access to water that is safe for human consumption. This problem extends beyond surface water, as pollution from factories and farms is also contaminating underground water reserves.

A government report revealed that farmers' fields are a bigger source of water contamination than factory effluent due to the overuse of fertilisers and pesticides. The immense size of China's agricultural sector and its massive dependency on artificial farm inputs, such as fertilisers, contribute to this issue. According to a study by Renmin University in China and Greenpeace, Chinese farmers use 40% more fertiliser than necessary. This has led to agricultural pollution becoming one of China's most severe environmental crises, endangering both surface and groundwater sources.

The impact of factory waste on underground water reserves cannot be understated. In 2011, it was reported that Luliang Chemical Industry in Yunnan province had disposed of 5,000 tonnes of chemical waste near a river used as a drinking water source. Over the years, more than 140,000 tonnes of waste had accumulated, highlighting the significant threat posed by industrial pollution to underground water sources.

Additionally, China's coastal areas are facing acute pollution problems. A Chinese government body reported that the size of the worst-affected areas increased by 50% in 2012. Coastal cities discharge excessive amounts of sewage and pollutants into the sea, further degrading water quality.

The contamination of underground water reserves in China has raised alarms among Chinese citizens, who are increasingly concerned about the health threats posed by pollution. While the Chinese government has stepped up efforts to address water pollution, the problem persists, and local governments often fail to crack down on polluting industries.
