Humans are made of water and bones with a thin covering of skin to hold it all in place. Up to 60 percent of the human adult body is water. Individual body parts may contain more. For example, the human brain and heart are composed of 73% water, and the lungs are about 83% water. Every day we need to consume a certain amount of water to survive. For adult males that’s about 3 liters a day while an adult female needs about 2.2 liters per day. That’s a lot of water when you think about how many people are on the earth!
We don’t just need water, we need drinking or potable water with low levels of harmful materials and sediment. To get that water we need water purification systems. Water purification is the process of removing undesirable chemicals, biological contaminants, suspended solids and gases from water. This is to get it ready for human consumption.
Some of the methods used in water purification include:
All of these processes are carried out to meet the standards set by government or international standards. You also can’t measure the purity of water by looking at it, it has to be tested to make sure it meets the health and hygiene standards adopted by the authorities.
1. Diseases and ailments
The benefits of access to pure and clean water that has been properly purified are many and varied. It may be easier to describe the dangers that are posed by unsafe drinking water. They include a range of diseases and ailments, some of which are a clear and present danger to human life.
The World Health Organization estimates that over one billion people across the world lack access to a safe drinking water supply. They trace this lack of clean water directly to almost 90 percent of the 4 billion cases of diarrheal disease that happen every year. Of which, nearly two million people die from on annual basis.
2. Inadequate sanitation
Almost all of these cases and deaths could be prevented and avoided by making changes to their water supply and ensuring that is free from the bacteria that causes their diseases. According to WHO, they note that even simple improvements to their sanitary living conditions through water purification methods like chlorination, filters, and solar disinfection, and storing water in safe containers could save a huge number of lives each year
3. Poor health outcomes for children
Drinking impure or contaminated water is the leading cause of epidemic disease in developing countries and children will drink what water is available. That leads to a high susceptibility to a range of childhood diseases that could come from more than 2100 known contaminants that may be present in untreated water, including a number of known poisons and carcinogens.
Even in North America and the developed world, there are still dangers if the drinking water supply is not fully purified and dangerous bacterial contaminants are not removed. It has been proven that clean, healthy drinking water is essential to a child’s proper mental and physical development. Dangerous minerals in water, like lead, if not removed can also lead to learning disorders and stunted development of young children.
4. Dangers for pregnant women
Pregnant women are at particular risk from impure or unsafe drinking water. A Princeton University study found that they are more likely to have babies that are premature or have low birth weights than women who have a safe and purified water supply.
They examined birth records for over ten years and compared areas with full water purification systems to those with low or poor systems. They found large and statistically significant effects on birth weight and gestation of infants born to women who did not have access to good, clean water on a regular basis.
