China's Water Pollution: Who Is To Blame?

Water pollution in China is a pressing issue, with half of the country's population lacking access to safe drinking water. The problem has been exacerbated by the discharge of industrial and agricultural waste, as well as poor environmental regulations and weak enforcement. This has led to severe pollution of China's water sources, with high levels of arsenic, fluorine, and sulfates present. The impact of this pollution is felt most strongly in rural areas, where two-thirds of the population relies on tainted water, leading to a high prevalence of cancer and other diseases. While the Chinese government has implemented policies such as the River Chief System to address water pollution, the problem persists and is predicted to worsen in the future.

Water pollution in China is the worst environmental issue

Water pollution in China is a pressing issue with far-reaching consequences. The country's water resources are already limited, with China's water resources estimated to be only 2,000 cubic meters per capita, a quarter of the global average. This scarcity is further exacerbated by pollution, which renders much of the available water unusable. According to some estimates, about 50% of China's shallow groundwater is polluted due to agricultural runoff and chemical waste from factories.

The pollution of water sources in China has severe health implications for its citizens. Half of the country's population lacks access to water that is safe for human consumption, and two-thirds of rural dwellers rely on tainted water. The water sources contain toxic levels of arsenic, fluorine, and sulfates, and pollution has been linked to high rates of liver, stomach, and esophageal cancer in certain areas. These areas have become known as "cancer villages".

The primary sources of water pollution in China are industrial wastewater, domestic sewage, agricultural hazardous pesticides, and manure. The discharge of these pollutants has contaminated both surface water and groundwater. Despite the closure of thousands of pollutant sources, a significant portion of China's waterways remain below the government's modest standards for water quality. This is particularly prevalent in rural areas, which often lack systems to treat wastewater.

While the Chinese government has taken steps to address water pollution, such as the introduction of the River Chief System (RCS) to streamline water governance, the effectiveness of these measures has been varied. Wealthier cities with stronger environmental restrictions have generally seen more significant improvements, while less developed regions continue to struggle with severe water quality issues due to limited budgets.

The issue of water pollution in China is made more complex by the demand for cheap goods from multinational companies, who may turn a blind eye to their suppliers' environmental practices. Additionally, underground water pollution is often invisible, receiving less public attention and pressure compared to visible air pollution. However, organizations like the Detox campaign are working to challenge multinational companies and raise awareness of the issue.

Poor water quality and scarcity

China's water scarcity is a growing problem, with the country's water resources estimated at only 2,000 cubic meters per capita, a quarter of the world's average level. China's large area, varied topography, and uneven distribution of water resources have led to it being listed as one of 13 countries with a water shortage by the United Nations.

The impact of poor water quality on water scarcity is complex and multifaceted. While the exact relationship is unclear, inadequate water quality exacerbates water scarcity, particularly in a regional context. China's dramatic economic development has come at an environmental cost, with widespread land use changes, increasing volumes of untreated wastewater, and agricultural runoff severely polluting the aquatic environment. This pollution affects both surface water and groundwater, with only 81.6% of rivers, 25% of lakes, 87.3% of reservoirs, and 23.9% of shallow groundwater meeting drinking water supply source criteria in 2018.

The discharge of industrial wastewater, domestic sewage, agricultural hazardous pesticides, and manure has significantly contributed to water pollution in China. Additionally, the effects of perfluorinated compounds (PFCs) and pharmaceutical and personal care products (PPCPs) on drinking water quality are becoming increasingly concerning. The demand for safe drinking water is rising due to the increasing population and accelerated urbanization, further straining water resources.

Climate change is also expected to worsen China's water scarcity and supply volatility. Increased glacial melting may provide a temporary boost to water supplies, but the long-term impact of climate change will lead to more frequent and severe extreme weather events, making water scarcer, more unpredictable, and more polluted. Southern China, for example, has experienced its longest drought on record, causing widespread industrial disruption and highlighting the region's water supply and demand imbalance.

The Chinese government has recognized the urgency of addressing water pollution and scarcity issues. In 2015, they issued the Action Plan for Prevention and Control of Water Pollution to strengthen pollution control and ensure drinking water safety. Additionally, the National Health Commission launched a revision of drinking water quality standards in 2018, aiming to improve water quality in both urban and rural areas.

Industrial and agricultural waste

China's water pollution crisis is a complex issue that has severe implications for public health and the environment. Industrial and agricultural waste are significant contributors to this problem, and addressing these sources of pollution is crucial for improving water quality in China.

Agricultural Waste

Agriculture is a major source of water pollution in China, accounting for more than half of the country's water pollution. Fertilizers, pesticides, and livestock waste are washed into lakes, rivers, wetlands, coastal waters, and underground aquifers by rainfall and snowmelt. This type of pollution, known as agricultural non-point source pollution, is challenging to control because it cannot be traced back to a single source. High nutrient levels from fertilizer runoff, for example, can cause mats of thick algae to form, as seen in Liaoning Province.

The overuse of fertilizers and the discharge of agrochemicals, organic matter, drug residues, sediments, and saline drainage by farms contribute to water contamination. In addition, a new class of agricultural pollutants has emerged in the form of veterinary medicines (antibiotics, vaccines, and growth promoters), which can enter drinking water sources and ecosystems. The livestock and poultry industry, driven by the rising demand for meat products, has also become an increasingly significant source of water pollution.

Industrial Waste

Industrial wastewater has historically been the major culprit of water pollution in China. The rapid industrial transformation over the past few decades has led to an increase in large-scale energy and metallurgy production, resulting in more pollutant discharges. Small-scale manufacturing plants and family-based workshops often use outdated and inefficient technologies, generating large amounts of industrial waste and wastewater without proper treatment. Heavy metal companies and plants are among the top industrial polluters, with their wastewaters containing high levels of heavy metals, organic pollutants, and nitrogen.

Addressing the Issue

China recognizes the severity of its water pollution problem and has taken steps to address it. The Chinese government has invested in the water-treatment sector and implemented plans such as the Action Plan for Prevention and Control of Water Pollution to strengthen pollution control and ensure drinking water safety. The Detox campaign by Greenpeace also aims to publicize the relationship between multinational companies, their suppliers, and water pollution in China, challenging companies to eliminate hazardous chemicals in water sources.

Ineffective government policies

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 has various causes, including industrial wastewater, agricultural runoff, and chemical waste from factories. While the Chinese government has implemented policies to address water pollution, some of these policies have been ineffective in mitigating the issue.

One example of ineffective government policies is the lack of comprehensive and effective regulations to limit and reduce pollutants, such as EDCs (endocrine-disrupting chemicals), which are generated during human activities and discharged into water environments. Insufficient monitoring and management of these chemicals have contributed to the deterioration of surface water and groundwater quality.

Additionally, China's water pollution control efforts have faced challenges due to poor environmental regulations, weak enforcement, and local corruption. Factories have been able to freely discharge wastewater into lakes and rivers, leading to severe contamination. Rural communities located near these industrial complexes are forced to rely on polluted water sources, resulting in high rates of cancer and other health issues.

Furthermore, the impact of agricultural waste and farm fertilizer on water contamination has been overlooked. China's water sources are tainted with toxic levels of arsenic, fluorine, and sulfates, which have been linked to the country's high rates of liver, stomach, and esophageal cancer. The government's failure to adequately address these issues highlights the ineffectiveness of their policies.

While the Chinese government has shown a strong political will to improve environmental quality and has prioritized environmental protection over economic growth, the implementation of their policies has fallen short. The "Water Pollution and Control Action Plan" (Water Ten Plan), issued in 2015, aimed to guide national water pollution prevention. However, despite this plan and the closure of thousands of pollutant sources, a significant portion of China's waterways remain below the government's modest standards for water quality.

Health impact and public awareness

Water pollution in China has been linked to serious health consequences, with approximately 700 million people—over half the population—consuming drinking water contaminated with levels of animal and human excreta that exceed maximum permissible levels by up to 86% in rural areas and 28% in urban areas. The discharge of industrial wastewater, domestic sewage, agricultural hazardous pesticides, and manure has polluted both surface water and groundwater, with only a small percentage of water sources meeting the criteria for drinking water supply. This has led to a high prevalence of infectious and parasitic diseases, as well as exposure to industrial chemicals, heavy metals, and algal toxins.

The health impact of water pollution in China is a significant public health issue. According to the World Bank, China's water pollution crisis could have "catastrophic consequences for future generations." The country's water supply has been contaminated by the dumping of toxic human and industrial waste, with two-thirds of its rural population relying on tainted water. This has resulted in "cancer villages," where communities located near factory complexes depend on contaminated water and experience high rates of cancer and death.

China's rapid socioeconomic development and urbanization have exacerbated the water pollution problem. Inadequate investment in basic water supply and treatment infrastructure has resulted in widespread water pollution, with the volume of wastewater produced doubling between 1990 and 2000. The government has implemented plans such as the Action Plan for Prevention and Control of Water Pollution to strengthen pollution control and ensure drinking water safety. However, the complexity of the water environment and the lack of coordination between environmental and public health objectives pose significant challenges.

Public awareness about drinking water safety and contamination accidents in China is varied. Studies have shown that respondents with some information about their water quality are more confident in their drinking water and supportive of water safety and pollution prevention measures. Educational level and drinking water quality health monitoring can influence public awareness. The Chinese government has also recognized the importance of enhancing health risk assessment systems and improving environmental health surveillance. Additionally, organizations like Greenpeace have launched campaigns to raise awareness and address water pollution, providing hope for the future.

Climate change further complicates the issue, impacting precipitation, evaporation, and the global hydrological cycle, leading to water scarcity and quality issues. China's water resources are estimated to be only 2,000 cubic meters per capita, a quarter of the world's average level, and the country is listed as one of 13 countries with a water shortage by the United Nations. As a result, China will likely experience severe water stress in the near future, emphasizing the urgency of addressing water pollution and scarcity.
