Why can’t you drink tap water in South Korea?

The Quality of Tap Water in South Korea

South Korea is a country that has made tremendous strides in economic and technological advancements. However, when it comes to the quality of tap water, the country still lags behind. The reasons for this are numerous, and in this article, we will explore them in detail.

Limited Natural Resources

South Korea is a country with limited natural resources, and it relies heavily on imported oil and gas. This means that the country has to work harder to produce clean drinking water. The government has set up several water treatment plants to purify water from rivers, lakes, and underground sources.

The Presence of Harmful Chemicals

Although the water treatment plants do a good job of removing harmful bacteria and viruses, they do not always remove harmful chemicals such as lead, mercury, and other heavy metals. These chemicals can be particularly harmful to pregnant women and young children.

Pollution in Urban Areas

South Korea is a densely populated country, and many of its urban areas suffer from pollution. This pollution can seep into the groundwater, which is the source of tap water. Even small amounts of pollution can be harmful to human health.

Aging Infrastructure

The infrastructure used to transport tap water from treatment plants to households is aging. This means that there are often leaks in pipes that allow contaminants to enter the water supply. In some cases, these leaks are so severe that the water supply has to be turned off for extended periods while repairs are made.

The Prevalence of Microplastics

Microplastics are tiny plastic particles that can be found in tap water. These particles come from a variety of sources, including plastic bottles, synthetic clothing, and even car tires. The long-term effects of ingesting microplastics are not yet known, but they are believed to be harmful.

Safety Concerns

Given the many issues with tap water in South Korea, many people are understandably concerned about its safety. This has led to a booming bottled water industry, with many Koreans opting for bottled water over tap water.

Environmental Impact

The reliance on bottled water has a significant environmental impact. The production and transportation of plastic bottles contribute to greenhouse gas emissions and plastic waste. Additionally, the disposal of plastic bottles can be problematic, with many ending up in landfills or oceans.

The Cost of Bottled Water

For many Koreans, the cost of bottled water is prohibitive. Bottled water is often more expensive than tap water, and this can be a significant financial burden for low-income families.

Alternative Sources of Drinking Water

Given the issues with tap water in South Korea, many people have turned to alternative sources of drinking water. Some people install filtration systems in their homes, while others opt for water delivery services or purchase spring water from natural sources.

Government Initiatives

The South Korean government has recognized the issues with tap water and has taken steps to address them. In recent years, the government has invested millions of dollars in upgrading infrastructure and improving water treatment plants.

Education and Awareness

Education and awareness campaigns are crucial in helping people understand the issues with tap water in South Korea. By educating people about the risks associated with contaminated water and promoting alternative sources of drinking water, the government can help to reduce reliance on bottled water.

The Future of Tap Water in South Korea

Although there are many challenges associated with tap water in South Korea, there is hope for the future. With continued investment in infrastructure and technology, it is possible to improve the quality of tap water and reduce reliance on bottled water. Additionally, education and awareness campaigns can help to change people’s attitudes towards tap water and promote safer drinking practices.

Why do Koreans not drink tap water?

According to experts, one of the main reasons why Koreans avoid drinking tap water is because of their sensitivity to the chlorine used in the water treatment process, which causes an unpleasant taste and smell. This taste and smell can lead to public distrust towards tap water. This was stated on May 26, 2015.

Is it bad to drink tap water in Korea?

In short, the water is safe to drink.

Why do Koreans only drink bottled water?

In Korea, bottled water or household water purification systems are highly preferred by locals. This is due to a widespread belief that such water is healthier than tap water. Despite various efforts to encourage the consumption of tap water through public campaigns, this belief remains prevalent.

Why is it bad to drink tap water in other countries?

Numerous diseases, such as travellers’ diarrhoea, cholera, typhoid, and hepatitis A, are caused by consuming contaminated food and water. Among them, travellers’ diarrhoea is the most frequently encountered illness among people who travel abroad, affecting anywhere between 20 to 60 percent of travellers.

Does Korea use toilet paper or water?

In many Asian countries such as China, Singapore, Thailand, Korea, and Taiwan, water is the preferred method of cleaning oneself. It can be difficult to find toilet paper in stores in these countries, although some hotels may provide it in guestrooms.

Where is the cleanest water in the world?

Icelandic water has a compliance rate of 99.44% with water safety standards, making it one of the best drinking waters worldwide. Although 6% of the country is covered by freshwater sources, most of the water is obtained from underground aquifers.

Collaboration with International Organizations

In addition to government initiatives, South Korea can also benefit from collaborating with international organizations that specialize in water treatment and management. By partnering with experts from around the world, South Korea can access cutting-edge technologies and best practices in water management.

Encouraging Sustainable Practices

The government can also encourage sustainable practices such as rainwater harvesting and graywater reuse. These practices can reduce the demand for tap water and alleviate pressure on the water supply. Additionally, promoting the use of reusable water bottles can help to reduce waste from single-use plastic bottles.

Involving Citizens in Water Management

Involving citizens in water management can also help to improve the quality of tap water. The government can encourage citizen-led initiatives such as community cleanups and monitoring programs. This can help to raise awareness about the impact of pollution on water quality and promote a sense of ownership among citizens.

Investing in Research and Development

South Korea has a robust research and development sector that can be leveraged to develop innovative solutions for improving water quality. The government can invest in research on new technologies for water treatment and pollution control, as well as research on the long-term effects of microplastics on human health.


The quality of tap water in South Korea is a complex issue that requires a multi-faceted approach. By investing in infrastructure, collaborating with international organizations, and promoting sustainable practices, South Korea can improve the quality of tap water and reduce reliance on bottled water. Additionally, education and awareness campaigns can help to change people’s attitudes towards tap water and promote safer drinking practices. With concerted effort, it is possible to ensure that all Koreans have access to safe, clean drinking water.
