Introduction Having clean water is a very crucial aspect of health. Many people don’t have access to clean water, this can be life threatening. There are lethal bacterial infections that are present in water. There are many different diseases that can acquire by drinking contaminated water like: cholera, typhoid fever, and dysentery. The biggest concern and issue is the ingestion of water that is contaminated with fecal matter (1). It has been discovered that the main source of bacteria is this fecal contamination. Fecal matter can enter water sources by runoff from farms or any area that contains many animals. This contamination can also come from insects, rats, or other small animals entering wells or water sources (2). Testing the quality of water, it is often common to test if the water contains coliforms. It is easier to test for coliforms, instead of testing for bacteria that can cause each waterborne disease. Coliforms are gram negative, facultative anaerobic bacteria that do not form endospores. They are also rod shaped and will ferment lactose (slides). When they ferment lactose, this will produce acid and gas. This acid and gas production will allow the total coliform count to be determined.
A major challenge and cause of serious medical issues in Sub-Saharan Africa is the lack of access to a clean water supply. There are 345 million people that lack access to water in Africa. Unfortunately, when water is available it is high in contamination. When wells are built and water sanitation facilities are developed, they cannot be maintained properly to due to limited financial resources. Water quality testing is not performed as often as necessary and the people are unaware that the water may not be safe to drink. Oftentimes, when a source of water has been provided, the quantity of water is often given more attention over the quality of. Lack of clean drinking is the leading cause of diarrheal diseases in Sub-Saharan Africa and causes 7.7% of deaths in Africa. Diarrhea is caused by numerous bacterial, viral and parasitic organisms most of which can be spread by contaminated water. The importance of diarrheal diseases has mostly been overlooked. Through UNICEF and the World Health Organization (WHO) there have been some accomplishments during the

Bacteriological quality standards are used to prevent diseases and sicknesses that can be contracted through the uses of the river’s water, such as swimming. Escherichia Coli (E. coli), a harmful group of bacteria commonly found in the intestine of animals and humans, is used as an indicator of pathogens. (Figure 3) Another indicator is the Total Coliform quality which is the total number of Coliform bacteria, such as E. coli, which exist in the river. Coliform bacteria is used as an indicator because they usually exist where other pathogens of fecal origins exists. Although disinfection periods try to clean the water, the

Thesis statement: Fresh and clean water is vital to the very existence of the human race.
How Does Access to Water Improve Health? Access to water is a human right, closely linked to the right to nutrition and wellbeing, so how is it that nearly 900 million people around the world have limited to no access to uncontaminated, fresh and safe water? It is a known fact that everyone needs water to stay hydrated, but the need for water stretches more than just hydration, along with food, it is the key to good health, so how does access to water improve health? First of all, the time spent to collect the water could be used by going to school and getting a good education. Without a good education, important life features cannot be reached, such as, a good job which leads to a good income. This means that food and other resources can be
How many of you, when you go to a restaurant and the waiter/waitress asks you what you want to drink ask for water?

Water is pure substance while its bond strength between hydrogen and oxygen is extremely strong. In addition, water is very important for both human beings and creatures and also it is essential for health, hygiene and the productivity of the world. However, almost all the supply of water in the world must contain organic material, chemicals, minerals and manmade pollutants, which might result in undrinkable or polluted solution. Moreover, the polluted solution contains deadly bacteria and viruses, which might cause some disease. According to American Geoscience Institute (2015), water is a scarce resource, which cannot be recovered after consuming. It states that most of the fresh water that is available for creatures is both contained in soil and rock below the surface. That is, the portable water account for a low percentage of total water in the world. Therefore, water plays an important role in the world, and also creatures cannot live without cleaning water; hence, water treatment becomes an important issue that should be seriously concerned gradually. This essay will explain some major design of water treatment filter in the world and it will firstly focus on a variety types of water treatment filters, demonstrating and suggestion of design parameter for water treatment filter; Next, demonstrating the appropriate design for sustainability; and finally, comparing the difference of water treatment filter between developed and developing countries
Furthermore, the access to fresh water provides minerals that also fight these deficiencies’. The quality of water is vital and an important health matter. When there is a shortage of clean water there is a chance that the occurrence of bacteria that cause diarrhea and cholera are present. Bacteria like, “diarrhea most often results from the ingestion of pathogens from excrement that has not been disposed of properly, or from the lack of hygiene” (Who.int. 2011). By implementing a plan to ensure that the water quality is safe is of utmost importance given the numerous risks
The global burden of infectious diarrhoea involves 3-5 billion cases and nearly 1.5 million deaths annually, mainly in young children, due to diarrhoeal disease caused by contaminated food and water.

A direct relationship exists between water, sanitation, health, nutrition and human well being. Consumption of contaminated drinking water, improper disposal of human excreta, lack of personal and food hygiene and improper disposal of solid and liquid waste have been the major causes of diseases in our country. There has been a key focus in various government programmes like the Total Sanitation Campaign to spread the message of maintaining personal hygiene for reducing water pollution. Better linkages between ministries of health and rural development for developing programmes to solve problems of drinking water and health will be useful.
Cool dew on the grass, bursting grey clouds, and the digestive system working our food through our body, are just a few examples of how water is used in our everyday lives. Water is the most vital liquid on Earth, making everything possible for survival. Although we have plenty of water on Earth, only 1% of it is human accessible and useable, so water preservation is crucial. Pollution from cars, factories, and mines are polluting our water and air as we speak, causing many species to suffer each day. Communities need to take action, and start helping to clean and preserve our water. Due to the importance of water in our bodies and environment, we need to start helping the environment today.
Having clean water cannot be exaggerated when it comes to prevent diseases and death. Clean water and sanitization are important elements to ensure human health. The same is right for appropriate wastewater management, which is a basic requirement for environmental health. Indeed, human and environment health impact not only on human but also effect the world economic outcomes.
Although the state of America’s water infrastructure is of great concern, the types of chemicals found in America’s tap water are equally as frightening. The passage of the Water Act in 1972 prevents the direct dumping of hazardous chemicals directly into waterways, and helps regulate quality standards of water. However, the Clean Water Act is has no jurisdiction on regulating indirect dumping of chemicals that integrates into water supplies. Pesticides and prescription drugs are the greatest cause for concern of indirect containments in America’s water supply (Olsen). An abundance of the harmful chemicals found in liquefied animals feces, used in large dairy states, have percolated into drinking wells that have caused serious infections (Duhigg). However, more harmful containments are infiltrating water supplies. Such containments include
