Water pollution in China is a pressing issue, with the country facing dangerous levels of water contamination that threaten the health and survival of its citizens. China's rapid economic growth, industrialization, and urbanization have led to widespread water pollution, exacerbated by inadequate investment in water treatment infrastructure. The situation is so severe that, in some cities, up to 85% of water in major rivers is undrinkable and unfit for any purpose, with high levels of animal and human excreta, toxic industrial waste, and agricultural runoff. With China being the world's biggest water user, accounting for 13% of global freshwater consumption, the impact of this pollution is far-reaching and has been linked to high rates of cancer and other illnesses.
What You'll Learn
Industrial and human waste
China's water pollution crisis is largely due to the dumping of toxic human and industrial waste. In 2015, 3.78 billion cubic meters of untreated wastewater was discharged across China, with 1.98 million cubic meters in Beijing alone. This wastewater, used in homes, businesses, and industries, contains hazardous materials and is dumped into rivers and lakes, rendering it unusable for any purpose.
China's rapid economic growth, industrialization, and urbanization have resulted in inadequate investment in basic water supply and treatment infrastructure, leading to widespread water pollution. The country's demand for cheap goods and rapid development have come at the cost of environmental health, with factories freely discharging wastewater due to poor environmental regulations, weak enforcement, and local corruption. This has had severe consequences for human health, with approximately 700 million people consuming drinking water contaminated with animal and human waste.
The impact of industrial waste on water pollution is significant. China's coastal manufacturing belt, home to many factories, faces severe pollution. These factories discharge wastewater containing hazardous chemicals into water sources, impacting both the environment and human health. In 2005, a chemical explosion at a petrochemical plant spilled 100 tons of pollutants into the Songhua River, leaving 3.8 million residents without water for four days.
The issue of human waste cannot be understated. In China, 80% of groundwater from major river basins is deemed "unsuitable for human contact." This is due to the overuse of chemicals in farming, as well as the lack of proper sewage and wastewater treatment infrastructure. The impact of agricultural waste has been doubled due to its initial ignorance in government predictions, with farm fertilizers significantly contributing to water contamination.
Water pollution in China is a severe environmental and public health issue. It is caused by the dumping of toxic industrial and human waste, exacerbated by rapid economic growth and industrialization. The contamination of water sources with hazardous chemicals and waste has led to a water crisis, threatening the health and well-being of millions of people across the country.

Poor environmental regulations
China's development has been remarkable, lifting many people out of poverty. However, this progress has come at a cost. Factories and industrial sites have been allowed to freely discharge their wastewater into nearby lakes and rivers due to lax environmental regulations, weak enforcement, and local corruption. This has resulted in the contamination of water sources with toxic levels of chemicals, heavy metals, and industrial waste.
The impact of agricultural waste on water pollution has also been significant. Farm fertilizer has contaminated water sources with high levels of arsenic, fluorine, and sulfates, posing serious health risks to those who consume it. China's growing demand for food and agricultural products has led to the overuse of chemicals in farming, further exacerbating the problem.
The Chinese government has recognized the severity of the issue and has taken some steps to address water pollution. In 2015, the Action Plan for Prevention and Control of Water Pollution was introduced to strengthen pollution control and ensure drinking water safety. Additionally, the "Healthy China 2030" initiative emphasizes the importance of health risk assessment systems in environmental health issues. However, the implementation and enforcement of these measures remain challenging.
The water pollution crisis in China is not just a quality of life issue, but a matter of survival for many. Access to clean drinking water is becoming increasingly scarce, and the contamination of water sources has severe consequences for human health. It is imperative that China continues to prioritize environmental efforts and work towards improving the quality and accessibility of drinking water for its population.

Climate change
China's water crisis is influenced by both natural and human factors. The country's northern regions are arid due to their natural geography and climate patterns, but human activities have exacerbated these effects. Overgrazing by livestock has turned grasslands into sandy deserts, causing ecosystems to lose their natural water-trapping capabilities and further contributing to water scarcity.
China's rapid urbanization, economic development, and industrialization have placed increasing pressure on water resources. Rivers, lakes, and aquifers, which have been vital sources of freshwater for thousands of years, are now facing the challenges of pollution and depletion. The demand for water-intensive industrial manufacturing, household plumbing, agriculture, and energy production further strains water availability.
The Chinese government has recognized the urgency of the situation and has taken steps to address water pollution and ensure drinking water safety. Initiatives such as the Action Plan for Prevention and Control of Water Pollution (2015) and the "Healthy China 2030" Initiative reflect a growing awareness of the health risks associated with water pollution and the need to enhance environmental health risk assessment systems.

Overuse of chemicals in farming
China's water crisis is both natural and man-made. The country is experiencing rapid urbanization, economic development, and industrialization, which are all contributing to the scarcity of clean water. China is the world's biggest water user, accounting for 13% of the world's freshwater consumption. The overuse of chemicals in farming is a significant contributor to water pollution in China.
China is the world's largest consumer of agricultural chemicals, using more than 30% of global fertilizers and pesticides on only 9% of the world's cropland. This is due to the small size of farms in China, which are typically around 0.1 hectares for each parcel of cropland. At such a small scale, many technological innovations and modern management practices are less effective due to the high costs of adoption. As a result, agricultural chemicals are often used inefficiently, leading to financial losses and serious local, regional, and global pollution. Eutrophication, caused by an excess of nutrients in bodies of water, is a common issue, as well as particle pollution in the air and global warming.
The Chinese government has made efforts to reduce the excessive use of agricultural chemicals, but the effects have been limited. Removing policy distortions that sustain small farm sizes could substantially decrease the use of agricultural chemicals and their environmental impact while increasing rural income. However, this would require both policy changes and institutional reforms, which may not occur in the short term due to the profound implications of such reforms.
The overuse of chemicals in farming has resulted in enormous damage to environmental quality and human health in China. Water pollution has been linked to the country's high rates of liver, stomach, and esophageal cancer. About 300 million people in China drink contaminated water every day, and almost two-thirds of these people fall ill.
To combat water pollution, Greenpeace launched the Detox campaign in 2011 to publicize the relationship between multinational companies, their suppliers, and water pollution in China. The campaign challenges multinational companies to work with their suppliers to eliminate all instances of hazardous chemicals being released into water sources. While continued efforts from organizations like the Detox campaign provide hope for the future, addressing the overuse of chemicals in farming is critical to the sustainable development of Chinese agriculture and the health and well-being of its people.

Lack of sewage treatment
China's water crisis is both natural and man-made. The country is experiencing rapid urbanization and economic development, which has led to an increase in water usage and a decrease in clean water sources. China is the world's biggest water user, accounting for 13% of the world's freshwater consumption. This water is used for drinking, washing clothes, bathing, cooking, cleaning, industrial manufacturing, household plumbing, raising agriculture and livestock, and producing energy.
One of the major causes of water pollution in China is the lack of sewage treatment. Most of China's rural areas lack a system to treat wastewater, and only 6% of rural areas had wastewater treatment systems by the end of 2010, increasing to 19% by the end of 2018. In 2011, Greenpeace launched the Detox campaign to publicize the relationship between multinational companies, their suppliers, and water pollution in China. The campaign challenged multinational companies to work with their suppliers to eliminate the release of hazardous chemicals into water sources.
The water pollution in China is caused by the demand for cheap goods, with multinational companies ignoring their suppliers' environmental practices. This has led to dangerous levels of water pollution, sending many people into disease. Factories are able to freely discharge their wastewater into lakes and rivers due to poor environmental regulations, weak enforcement, and local corruption. Rural villages located near factory complexes rely on this contaminated water for drinking, washing, and cooking.
The Chinese government has made efforts to improve the situation, with the wastewater treatment sector in Shenzhen developing rapidly since the 2001 reform. The sewage treatment rate in the Shenzhen Special Economic Zone has increased from 56% during the pre-integration period to over 88% in 2008, ranking first among large and medium-sized cities in China. By June 2010, there were 1,519 municipal wastewater treatment plants in China, with 18 new plants added each week. Many existing plants are being expanded and upgraded to include a tertiary treatment stage for nutrient removal to comply with more stringent discharge standards introduced in 2002.
Despite these efforts, much remains to be achieved. According to a study on sewage characteristics in rural China, the biodegradability of rural wastewater is adequate, and the BOD5/COD ratio in sewage was 0.4, which is suitable for biological treatment. However, the study also found that the rural sewage in Shaanxi had a low carbon source content, which negatively impacts the efficient operation of the BNR system for nitrogen removal. Overall, China's rural areas still discharge a large amount of untreated sewage every year, hindering the process of improving the living environment in these areas.
