In developing countries, about 80% of illnesses are linked to poor water and sanitation conditions. Clean and safe water is essential to healthy living. Tiny worms and bacteria live in water naturally. Most of the bacteria are pretty harmless.

Here are some of the most effective water purification methods that have stood the test of time:

1. Boiling. The simplest method to purify water is to boil it for a good amount of time.
2. Water Purifier.
3. Reverse Osmosis.
4. Water Chlorination.
5. Distillation.
6. Iodine Addition.
7. Solar Purification.
8. Clay Vessel Filtration.

Draw Water from the Air: Developing governments can supply water to their nations by harvesting water from humid air. Atmospheric Water Generators, created by Watergen, generate water from thin air. This method involves dehumidifying clean air through a heat exchange system.

6% of deaths in low-income countries are the result of unsafe water sources. 666 million (9% of the world) does not have access to an improved water source. 2.1 billion (29% of the world) do not have access to safe drinking water.

Clean water is essential not only to remain safe from disease but also to maintain good health. If the crops and grains are given contaminated water, the bacteria and disease will spread to those who consume the fresh produce. Therefore, water that is used for agriculture must also come from safe and clean resources.

Water delivers important nutrients to all of our cells, especially muscle cells, postponing muscle fatigue. 2. Water helps weight loss. Water helps you feel full longer, without adding any additional calories.

Each person on Earth requires at least 20 to 50 liters of clean, safe water a day for drinking, cooking, and simply keeping themselves clean. Polluted water isn’t just dirty—it’s deadly. Some 1.8 million people die every year of diarrheal diseases like cholera.

Water is one of the most important substances on earth. All plants and animals must have water to survive. If there was no water there would be no life on earth. Apart from drinking it to survive, people have many other uses for water.

People need water for drinking, trade, and transportation.

Water plays many important roles in the body including flushing waste from the body, regulating body temperature, transportation of nutrients and is necessary for digestion. No wonder it is considered “essential!” Plain water is the best choice for hydrating the body.

The most common water uses include:

• Drinking and Household Needs.
• Recreation.
• Industry and Commerce.
• Agriculture.
• Thermoelectricity/Energy.

Water is used for drinking, bathing, cooking food and washing dishes, clothes, fruits, vegetables and brushing teeth.

Below are important uses of water in daily life.

• Cooking. Water has dissolving power that makes it vital in cooking.
• Bathing. Bathing involves washing the body by water or immersing the body inside water.
• Hydroelectric power.
• Drinking.
• Tourism.
• Recreation.
• Transportation.
• Industries.

Domestic water use is water used for indoor and outdoor household purposes— all the things you do at home: drinking, preparing food, bathing, washing clothes and dishes, brushing your teeth, watering the garden, and even washing the dog.

Outdoor watering accounts for almost 30 percent of water use, according to an analysis published by Environment Magazine. But toilets (19 percent), washing machines (15 percent), showers (12 percent), and faucets (11 percent) also use substantial amounts.

Domestic water use is probably the most important daily use of water for most people. Domestic use includes water that is used in the home every day, including water for normal household purposes, such as drinking, food preparation, bathing, washing clothes and dishes, flushing toilets, and watering lawns and gardens.

In the United States, approximately 37% of our drinking water comes from aquifers. We use groundwater every day to brush our teeth, flush the toilet, and irrigate our crops. Aquifers are a crucial part of the hydrologic cycle, the perpetual life cycle of all water on Earth.

A good example is the water of the Nubian Sandstone Aquifer System, which extends through several countries in an area that is now the Sahara. The water is being used extensively for water supply and irrigation purposes. Radioisotope dating techniques have shown that this water is many thousands of years old.

Topography and geology are the dominant factors controlling groundwater flow. Storativity describes the property of an aquifer to store water. Hydraulic conductivity is measured by performing a pumping test, i.e. by pumping one well and observing the changes in hydraulic head in neighboring wells.

In addition to groundwater levels, the quality of water in an aquifer can be threatened by saltwater intrusion (a particular problem in coastal areas), biological contaminants such as manure or septic tank discharge, and industrial chemicals such as pesticides or petroleum products.

Contaminants Found in Groundwater Industrial discharges, urban activities, agriculture, groundwater pumpage, and disposal of waste all can affect groundwater quality. Contaminants can be human-induced, as from leaking fuel tanks or toxic chemical spills.

Increasing populations, including those migrating from rural, infrastructure-lacking areas to job-supplying cities, and the negative effects of climate change conspire to pressure groundwater supplies. At least 2 billion people of the 7.6 billion on Earth use groundwater as their primary source of water.

San Diego Formation, an aquifer used for public water supply in San Diego County, California and Los Angeles, California. Turlock Basin, underlies the San Joaquin River in the San Joaquin Valley of central California. One of the largest aquifers in the Western United States.

Since groundwater that is very deep or below the oceans is saline, overpumping can cause the saltwater to move inland or upwards, resulting in saltwater intrusion, which can contaminate fresh drinking water. And when aquifers are overpumped, they can collapse, forever reducing their capacity to store water.
