Globally, boiling is still the most commonly used household water treatment (hereafter HWT) method. But boiling has its problems too. For one, after boiled water cools it can easily become contaminated again if, for example, a child places a dirty hand in the water, or if something falls into the water. Fuel is another issue. Because those without access to safe drinking water tend to be poorer households in rural areas, the fuels they use—such as wood, crop residues, or coal—produce air pollution that is almost as damaging to human health as cigarette smoke. Recent revealed that exposure to such household air pollution (HAP) is the largest single environmental health risk globally, and was responsible for an estimated 3.9 million deaths in 2010.
Water pollution is the process of contamination and littering of water resources. Water is the most valuable resource on the planet because it supports life of every organism. A human being is mostly composed of water, that is why the value of water is clearly obvious – without pure water we simply will not be able to survive. Unfortunately, people do not realize the necessity of protection of water resources, because they believe the amount of pure water is so great that it can not be exhausted. Evidently, only a small percent of the world’s water is considered to be good for drinking, because the water in the seas and oceans can be used only for industry. The water from rivers and lakes was generally believed to be good for drinking, but today it is too dirty even to swim there.
It is an undeniable fact that water is an important resource that determines life on earth.
Effects of Water Pollution
Fertilizers and pesticides that we use in our farms are dissolved in water, and some amount of these dissolved substances are washed into water bodies and pollute them.
- Ocean pollution is caused by a variety of sources, including oil and petroleum based products.
- Drinking Water Research Papers discuss the importance of drinking water in today's society.
Acid mine drainage also contaminates water.Water Pollutants and their Long Term Effects
2,4,5-T (trichlorophenoxy acetic acid, which contains the impurity dioxin), 2,4-D (dichlorophenoxyaceticacid) are the two common pesticide components that cause water pollution.
They are So, in order to avoid these harmful effects, follow the ways to prevent water pollution and more importantly, drink clean and purified water and never compromise on health.

Water pollution is a term that describes any adverse environmental effect on water bodies (lakes, rivers, the sea, groundwater) caused by the actions of humankind. Although natural phenomena such as volcanoes, storms, and earthquakes also cause major changes in water chemistry and the ecological status of water, these are not pollution. Water pollution has many causes and characteristics. Humans and livestock produce bodily wastes that enter rivers, lakes, oceans, and other surface waters. These wastes increase the solids suspended in the water and the concentration of bacteria and viruses, leading to potential health impacts.
Increases in nutrient loading may lead to eutrophication, or dead zones, in lakes and coastal water. Organic wastes deplete the water of oxygen, which potentially has severe impacts on the whole ecosystem. Industries and municipalities discharge pollutants, permitted and sometimes unpermitted, into their wastewater, including heavy metals, organic toxins, oils, pesticides, fertilizers, and solids. Discharges can also have direct and indirect thermal effects, especially those from nuclear power stations, and also reduce the available oxygen. Human activities that disturb the land can lead to silt running off the land into the waterways. This silt can have environmentally detrimental effects even if it does not contain pollution. Silt-bearing runoff comes from many activities, including construction, logging, mining, and farming. It can kill aquatic and other types of life. Salmon, for example, do not spawn if the temperature of the water is too high.
Water regulations control point sources of pollution. Some environmentalists consider the definition of point source to be too narrow because it allows smaller discharges into the water. It has been estimated that between 50 and 80 percent of water pollution comes from non-point sources. Non–point source (NPS) pollution comes from many sources, including human habitation and industrial emissions currently unaccounted for. NPS pollution begins with precipitation moving on and through the ground. As the force of gravity pulls the water down, it carries with it natural and human-made pollutants. Many of these pollutants end up in lakes, rivers, wetlands, coastal waters, and underground sources of drinking water. These pollutants include the following:
