China's Water Pollution: A Crisis Unveiled

China's water pollution is a pressing issue, with half the population lacking access to safe drinking water. The country's rapid economic growth, industrialization, and urbanization, coupled with inadequate investment in water treatment infrastructure, have resulted in widespread water contamination. China's water sources are tainted with toxic levels of arsenic, fluorine, and sulfates, leading to high rates of liver, stomach, and esophageal cancer. Water pollution in China is caused by industrial waste, chemical fertilizers, and raw sewage, with factories discharging wastewater into lakes and rivers due to poor environmental regulations, weak enforcement, and local corruption. The government has been working to address this issue, but the future remains uncertain.

Industrial and human waste

China's water pollution crisis is largely due to industrial and human waste. The country's rapid industrialization and urbanization have resulted in a significant increase in wastewater emissions, with factories discharging untreated hazardous waste and chemicals into lakes and rivers due to poor environmental regulations and weak enforcement.

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 is often dumped into rivers and lakes, rendering them unusable for agricultural, industrial, or decorative purposes. The agricultural sector, which requires around 30 cubic kilometers of water annually, also contributes to water pollution through the overuse of chemicals in farming. Pesticides and fertilizers can turn into toxic runoff that pollutes groundwater, and farm fertilizer has been a major contributor to water contamination in rural areas.

Human waste is another significant factor in China's water pollution crisis. According to estimates, over half of China's population consumes drinking water contaminated with levels of animal and human excreta that exceed maximum permissible levels. In rural areas, these levels can be as high as 86% above the limit, while in urban areas, they can still be 28% above the permissible limit. This has had serious consequences for public health, with water pollution linked to China's high rates of cancer, including liver, stomach, and esophageal cancer.

The Chinese government has made efforts to address the water pollution crisis, with the Ministry of Ecology and Environment (MEE) stepping up efforts and setting targets for provinces to improve water quality. However, local governments have often failed to crack down on polluting industries, and the nationwide standards for sewage treatment are insufficient. As a result, China's water pollution crisis persists, with access to clean drinking water becoming a matter of survival for many.

Poor environmental regulations

China's rapid industrialization and economic growth have had a detrimental impact on its water resources, and poor environmental regulations have exacerbated the problem.

China's industrialization has brought about a demand for cheap goods, which has led to a disregard for environmental practices among multinational companies and their suppliers. This has resulted in factories freely discharging wastewater into lakes and rivers due to lax environmental regulations, weak enforcement, and local corruption. The water pollution in China is so severe that it has led to the emergence of ""cancer villages,"" where rural communities located near industrial complexes rely on contaminated water for their daily needs.

The Chinese government has not turned a blind eye to the issue, and there is a growing appetite to address the environmental impacts of industrialization. The government has set objectives and targets for water quality improvement, such as the Thirteenth Five Year Plan in 2016, which aimed to reduce water consumption and increase wastewater treatment rates. However, the success of these initiatives depends on the capacity of the government to implement them effectively.

The complexity of administrative arrangements and the involvement of multiple ministries and jurisdictions further hinder the process of cleaning up China's water resources. The Law on Environmental Protection was modified in 2014 to enhance data transparency, and the Ministry of Ecology and Environment has been working to address water pollution through initiatives like the Water Pollution Prevention and Control Law. Despite these efforts, the impact of agricultural waste, particularly from chemical fertilizers, has been underestimated, contributing to the doubling of water pollution from the government's initial predictions.

While China has demonstrated its ability to reduce air pollution through swift government action and public pressure, similar vigilance is needed to tackle water pollution. Making water pollution data publicly available and holding local governments accountable are crucial steps in addressing this issue.

Lack of wastewater treatment

China is facing a severe water crisis, with water pollution being the country's worst environmental issue. The country's rapid urbanization, industrialization, and economic development have led to a significant increase in wastewater emissions, exacerbating water scarcity and inequality in access to clean water.

One of the main contributors to water pollution in China is the discharge of untreated industrial wastewater. Factories are often allowed to freely release their wastewater into water bodies due to weak enforcement of environmental regulations and local corruption. This has led to the presence of toxic chemicals, such as ammonia, cyanide, and arsenic, chromium, and mercury, in China's water sources. These pollutants have severe health impacts, with water pollution being linked to increased rates of cancer, particularly digestive, liver, stomach, and esophageal cancer.

Additionally, agricultural waste and runoff from farms have also played a significant role in water contamination. Farm fertilizers, such as pesticides and chemical waste, have contaminated water sources, further degrading water quality. The impact of agricultural waste on water pollution was previously underestimated, leading to the doubling of water pollution levels compared to the government's initial predictions.

The Chinese government has recognized the urgency of addressing water pollution and has taken several measures to combat the issue. In 2015, the State Council issued the Water Pollution Prevention and Control Action Plan, setting targets for improving water quality by 2030. The government has also invested billions of dollars in wastewater treatment and pollution control projects, and revisions have been made to the Water Pollution Prevention and Control Law to enhance regulation and enforcement.

While efforts are being made to address the lack of wastewater treatment and improve water quality, China continues to face significant challenges in ensuring access to clean and safe water for its vast population.

Government targets and standards

The Chinese government has launched several efforts to reduce water pollution. In 2015, China's State Council issued the Water Pollution Prevention and Control Action Plan, which set targets for improving water quality by 2030. The National People's Congress passed major revisions to the Water Pollution Prevention and Control Law in 2018, marking the first update to the law in a decade.

In 2017, China's environment ministry announced that the water quality rankings would only be released for the 10 best and 10 worst-performing cities, with Greenpeace research showing that nearly half of the country had missed its five-year water quality targets for the period 2011-2015. In 2018, the National Health Commission started a new round of revisions for drinking water standards, introducing environmental health risk assessments to set limit values.

In 2020, the Ministry of Ecology and Environment (MEE) announced a five-year plan to restrict farming near major rivers to limit water pollution from agricultural runoff. The MEE has also guided local governments to implement "Water" in Article 10, with goals including ensuring no large floating objects appeared on river surfaces, no garbage on river banks, and no illegal sewage discharge.

While the central government has set ambitious plans and targets, local governments have struggled to implement water quality standards. This is partly due to a lack of monitoring and incentives to achieve remediation targets. To address this, central authorities have encouraged nongovernmental organizations to monitor local governments' remediation efforts, which has been shown to improve water quality.

Impact on health and the environment

China's water pollution has had a significant impact on both public health and the environment.

Impact on Public Health

Over half of China's population consumes contaminated drinking water, which contains unsafe levels of animal and human excreta, as well as toxic levels of arsenic, fluorine, and sulfates. In rural areas, the levels of contamination can exceed maximum permissible levels by up to 86%. This has potentially serious consequences for human health, with water pollution linked to China's high rates of liver, stomach, and esophageal cancer. A health impact assessment of surface water pollution in 336 Chinese cities between 2015 and 2022 revealed a significant impact on digestive cancer, with annual average health impacts of oesophageal, stomach, colorectal, gallbladder, and pancreatic cancers amounting to 2621.20 thousand DALYs.

Impact on the Environment

China's water pollution has also had a detrimental effect on the environment, with severe surface water pollution and groundwater contamination in 90% of the country's cities. Pollution-induced algae blooms are visible on the surfaces of lakes, but the more significant issue of groundwater contamination lurks beneath. China's coastal manufacturing belt, in particular, faces significant pollution, with factories discharging wastewater into lakes and rivers due to poor environmental regulations, weak enforcement, and local corruption.

The country's water pollution is a result of its rapid economic growth, industrialization, and urbanization, coupled with inadequate investment in basic water supply and treatment infrastructure. Local governments have often failed to crack down on polluting industries, and rural areas lack systems to treat wastewater properly. As a result, China's water resources and ecosystem have been severely impacted, with lakes, rivers, and soil contaminated, and forests turned into plantations.

Addressing the Issue

Efforts to address water pollution in China have been made, with the Ministry of Environment stepping up initiatives and Greenpeace launching the Detox campaign in 2011 to publicize the relationship between multinational companies, their suppliers, and water pollution in the country. However, the same vigilance and public pressure that led to swift government action on air pollution are needed to tackle water pollution effectively.
