Drinking water or potable water is water that is safe for ingestion , either when drunk directly in liquid form or consumed indirectly through food preparation . It is often (but not always) supplied through taps, in which case it is also called tap water .
84-1055: Practical Action (previously known as the Intermediate Technology Development Group , ITDG ) is a development charity registered in the United Kingdom which works directly in four regions of the developing world – Latin America , East Africa , Southern Africa and South Asia , with particular concentration on Peru , Bolivia , Kenya , Sudan , Zimbabwe , Bangladesh and Nepal . In these countries, Practical Action works with poor communities to develop appropriate technologies in renewable energy , food production , agro-processing , water , sanitation , small enterprise development, building and shelter, climate change adaptation and disaster risk reduction . In 1965, economist and philosopher E. F. Schumacher had an article published in The Observer , pointing out
168-399: A 'typology of nationalizing, developmental, and neoliberal migration management regimes' across developing countries. Following independence and decolonization in the 20th century, most developing countries had dire need of new infrastructure , industry and economic stimulation. Many relied on foreign investment. This funding focused on improving infrastructure and industry, but led to
252-456: A breakdown or design fault in the sanitation system, or by chemical contaminants. Further examples of contamination include: Examples of chemical contamination include: Most water requires some treatment before use; even water from deep wells or springs. The extent of treatment depends on the source of the water. Appropriate technology options in water treatment include both community-scale and household-scale point-of-use (POU) designs. Only
336-452: A chronic health risk through buildup of heavy metals although some components like nitrates/nitrites and arsenic can have a more immediate impact. Physical parameters affect the aesthetics and taste of the drinking water and may complicate the removal of microbial pathogens. Pesticides are also potential drinking water contaminants of the category chemical contaminants . Pesticides may be present in drinking water in low concentrations, but
420-498: A clear definition, sustainability expert Mathis Wackernagel and founder of Global Footprint Network , emphasizes that the binary labeling of countries is "neither descriptive nor explanatory". Wackernagel identifies these binary terms of "developing" vs. "developed" countries, or "North" vs. "South", as "a thoughtless and destructive endorsement of GDP fetish." Wackernagel and Rosling both argue that in reality, there are not two types of countries, but over 200 countries, all faced with
504-559: A component of effective policy for health protection." In 1990, only 76 percent of the global population had access to drinking water. By 2015 that number had increased to 91 percent. In 1990, most countries in Latin America, East and South Asia, and Sub-Saharan Africa were well below 90%. In Sub-Saharan Africa, where the rates are lowest, household access ranges from 40 to 80 percent. Countries that experience violent conflict can have reductions in drinking water access: One study found that
588-523: A conflict with about 2,500 battle deaths deprives 1.8% of the population of potable water. Typically in developed countries , tap water meets drinking water quality standards , even though only a small proportion is actually consumed or used in food preparation. Other typical uses for tap water include washing, toilets, and irrigation . Greywater may also be used for toilets or irrigation. Its use for irrigation however may be associated with risks. Globally, by 2015, 89% of people had access to water from
672-575: A farmer might plan for 35 U.S. gallons (130 L) per day for a dairy cow , a third of that for a horse , and a tenth of that for a hog . However, relatively few studies have been focused on the drinking behavior of wild animals. According to the World Health Organization's 2017 report, safe drinking water is water that "does not represent any significant risk to health over a lifetime of consumption, including different sensitivities that may occur between life stages". According to

In emergency situations when conventional treatment systems have been compromised, waterborne pathogens may be killed or inactivated by boiling but this requires abundant sources of fuel, and can be very onerous on consumers, especially where it
840-462: A high climate vulnerability or low climate resilience . Developing countries often have lower median ages than developed countries. Population aging is a global phenomenon, but population age has risen more slowly in developing countries. Development aid or development cooperation is financial aid given by foreign governments and other agencies to support developing countries' economic, environmental, social, and political development .

Unlike developed countries, developing countries lack rule of law . Access to healthcare
1092-476: A medium to low standard of living . There is an association between low income and high population growth. The development of a country is measured with statistical indices such as income per capita (per person), gross domestic product per capita, life expectancy , the rate of literacy, freedom index and others. The UN has developed the Human Development Index (HDI), a compound indicator of some of
1176-877: A method of grouping countries based on their defining characteristics with regard to socioeconomics and politics . According to UN Trade and Development (UNCTAD), the Global South broadly comprises Africa, Latin America and the Caribbean , Asia (excluding Israel , Japan , and South Korea ), and Oceania (excluding Australia and New Zealand ). Most of the Global South's countries are commonly identified as lacking in their standard of living , which includes having lower incomes , high levels of poverty , high population growth rates , inadequate housing, limited educational opportunities, and deficient health systems , among other issues. Additionally, these countries' cities are characterized by their poor infrastructure . Opposite to

Sixty million people are estimated to have been poisoned by well water contaminated by excessive fluoride , which dissolved from granite rocks. The effects are particularly evident in the bone deformations of children. Similar or larger problems are anticipated in other countries including China, Uzbekistan, and Ethiopia. Although helpful for dental health in low dosage, fluoride in large amounts interferes with bone formation. Long-term consumption of water with high fluoride concentration (> 1.5 ppm F) can have serious undesirable consequences such as dental fluorosis , enamel mottle and skeletal fluorosis , bone deformities in children. Fluorosis severity depends on how much fluoride
1344-685: A non-partner (not including sexual harassment ) at some point in their lives. Evidence shows women who have had experienced physical or sexual intimate partner violence report higher rates of depression, having an abortion and acquiring HIV , compared to women who have not had experienced any physical or sexual violence. Data from the Middle East and North Africa shows that men who witnessed their fathers against their mothers, and men who experienced some form of violence as children, more likely have reported perpetrating intimate partner violence in their adult relationships. The status of healthcare that

Development can be measured by economic or human factors. Developing countries are, in general, countries that have not achieved a significant degree of industrialization relative to their populations, and have, in most cases,
1512-451: A report by UNICEF and UNESCO , Finland has the best drinking water quality in the world. Parameters for drinking water quality typically fall within three categories: microbiological, chemical, physical. Microbiological parameters include coliform bacteria , E. coli , and specific pathogenic species of bacteria (such as cholera -causing Vibrio cholerae ), viruses , and protozoan parasites . Originally, fecal contamination
1596-578: A source that is suitable for drinking – called improved water source – and 71% of the world could access safely managed drinking water that is clean and available on-demand. Estimates suggest that at least 25% of improved sources contain fecal contamination. 1.8 billion people still use an unsafe drinking water source which may be contaminated by feces . This can result in infectious diseases , such as gastroenteritis , cholera , and typhoid , among others. Reduction of waterborne diseases and development of safe water resources
1680-481: A source that is suitable for drinking – called improved water sources . In sub-Saharan Africa , access to potable water ranged from 40% to 80% of the population. Nearly 4.2 billion people worldwide had access to tap water, while another 2.4 billion had access to wells or public taps. By 2015, 5.2 billion people representing 71% of the global population used safely managed drinking water services. As of 2017, 90% of people having access to water from
1764-813: A system of systemic exploitation. They exported raw materials, such as rubber , for a bargain. Companies based in the Western world have often used the cheaper labor in developing countries for production. The West benefited significantly from this system, but left developing countries undeveloped. This arrangement is sometimes called neocolonialism , meaning a system in which less-developed countries are taken advantage of by developed countries. It does not necessarily mean that former colonies are still controlled by their former colonizer; it refers to colonial-like exploitation. Developing countries are often helping further develop rich countries, rather than being developed themselves. Several institutions have been established with

Plumbing can require significant capital investment. Some systems suffer high operating costs. The cost to replace the deteriorating water and sanitation infrastructure of industrialized countries may be as high as $ 200 billion
2100-436: Is a major public health goal in developing countries. In 2017, almost 22 million Americans drank from water systems that were in violation of public health standards, which could contribute to citizens developing water-borne illnesses . Safe drinking water is an environmental health concern. Bottled water is sold for public consumption in most parts of the world. Improved sources are also monitored based on whether water
2184-615: Is another form of violence against women which is still occurring in many developing countries. It is found mostly in Africa, and to a lesser extent in the Middle East and some other parts of Asia. Developing countries with the highest rate of women who have been cut are Somalia (with 98% of women affected), Guinea (96%), Djibouti (93%), Egypt (91%), Eritrea (89%), Mali (89%), Sierra Leone (88%), Sudan (88%), Gambia (76%), Burkina Faso (76%), and Ethiopia (74%). Due to globalization and immigration, FGM

While improved water sources such as protected piped water are more likely to provide safe and adequate water as they may prevent contact with human excreta, for example, this is not always the case. According to a 2014 study, approximately 25% of improved sources contained fecal contamination. The population in Australia, New Zealand, North America and Europe have achieved nearly universal basic drinking water services. Because of

Publicly available treated water has historically been associated with major increases in life expectancy and improved public health . Water disinfection can greatly reduce the risks of waterborne diseases such as typhoid and cholera . Chlorination is currently the most widely used water disinfection method, although chlorine compounds can react with substances in water and produce disinfection by-products (DBP) that pose problems to human health. Local geological conditions affecting groundwater are determining factors for

It could assume a desire to develop along the traditional Western model of economic development which a few countries, such as Cuba and Bhutan , choose not to follow. Alternative measurements such as gross national happiness have been suggested as important indicators. One of

Beyond citizenship, the study of the politics of cross-border mobility in developing countries has also shed valuable light in migration debates, seen as a corrective to the traditional focus on developed countries. Some political scientists identify

Other techniques, such as filtration, chemical disinfection, and exposure to ultraviolet radiation (including solar UV) have been demonstrated in an array of randomized control trials to significantly reduce levels of water-borne disease among users in low-income countries, but these suffer from the same problems as boiling methods. Another type of water treatment

The terms low and middle-income country ( LMIC ) and newly emerging economy ( NEE ) are often used interchangeably but refers only to the economy of the countries. The World Bank classifies the world's economies into four groups, based on gross national income per capita: high, upper-middle, lower-middle, and low income countries. Least developed countries , landlocked developing countries and small island developing states are all sub-groupings of developing countries. Countries on

It can also include poorer "southern" regions of wealthy "northern" countries. The Global South refers to these countries' "interconnected histories of colonialism , neo-imperialism , and differential economic and social change through which large inequalities in living standards, life expectancy, and access to resources are maintained".

Perfluorinated alkylated substances (PFAS) are a group of synthetic compounds used in a large variety of consumer products, such as food packaging , waterproof fabrics, carpeting and cookware. PFAS are known to persist in the environment and are commonly described as persistent organic pollutants . PFAS chemicals have been detected in blood, both humans and animals, worldwide, as well as in food products, water, air and soil. Animal testing studies with PFAS have shown effects on growth and development, and possibly effects on reproduction, thyroid,

In 2011, infectious diarrhea resulted in about 0.7 million deaths in children under five years old and 250 million lost school days. This equates to about 2000 child deaths per day. Children suffering from diarrhea are more vulnerable to become underweight (due to stunted growth ). This makes them more vulnerable to other diseases such as acute respiratory infections and malaria . Chronic diarrhea can have

4116-507: The WHO, the most common diseases linked with poor water quality are cholera , diarrhea , dysentery , hepatitis A , typhoid , and polio . One of the main causes for contaminated drinking water in developing countries is lack of sanitation and poor hygiene. For this reason, the quantification of the burden of disease from consuming contaminated drinking water usually looks at water, sanitation and hygiene aspects together. The acronym for this

The UN had set Millennium Development Goals from a blueprint developed by all of the world's countries and leading development institutions, in order to evaluate growth. These goals ended in 2015, to be superseded by the Sustainable Development Goals . The concept of the developing nation is found, under one term or another, in numerous theoretical systems having diverse orientations – for example, theories of decolonization , liberation theology , Marxism , anti-imperialism , modernization , social change and political economy . Another important indicator

4788-676: The further significant environmentally-related causes or conditions, as well as certain diseases with a strong environmental component: Access to water, sanitation and hygiene ( WASH ) services is at very low levels in many developing countries. In 2015 the World Health Organization (WHO) estimated that "1 in 3 people, or 2.4 billion, are still without sanitation facilities" while 663 million people still lack access to safe and clean drinking water. The estimate in 2017 by JMP states that 4.5 billion people currently do not have safely managed sanitation. The majority of these people live in developing countries. About 892 million people or 12 percent of

Many were governed by an imperial European power until decolonization . Political systems in developing countries are diverse, but most states had established some form of democratic governments by the early 21st century, with varying degrees of success and political liberty .

The ability of point of use (POU) options to reduce disease is a function of both their ability to remove microbial pathogens if properly applied and such social factors as ease of use and cultural appropriateness. Technologies may generate more (or less) health benefit than their lab-based microbial removal performance would suggest. The current priority of the proponents of POU treatment
5712-563: The other end of the spectrum are usually referred to as high-income countries or developed countries . There are controversies over the term's use, as some feel that it perpetuates an outdated concept of "us" and "them" . In 2015, the World Bank declared that the "developing/developed world categorization" had become less relevant and that they will phase out the use of that descriptor. Instead, their reports will present data aggregations for regions and income groups. The term " Global South "
