What Is Water Pollution? Additionally, water pollution may consist of chemicals introduced into the water bodies as a result of various human activities. Any amount of those chemicals pollutes the water, regardless of the harm they may pose to human health and the environment. Regardless of their provenance, the chemicals or biological agents causing water pollution are generically referred to as water pollutants.
Water they say is life, and indeed they were right. As young students, we learned about the various ways to conserve water ; coming to think of it, water is used in almost every important human chores and processes.
It is an Water pollution is the contamination of element in both domestic as well as industrial purposes. However a closer inspection of our water resources today, give us a rude shock.
Infested with waste ranging from floating plastic bags to chemical waste, our water bodies have turned into a pool of poison.
The contamination of water bodies in simplest words means water pollution. Thereby the abuse of lakes, ponds, oceans, rivers, reservoirs etc is water pollution. Pollution of water occurs when substances that will modify the water in negative fashion are discharged in it.
This discharge of pollutants can be direct as well as indirect.
Water pollution is an appalling problem, powerful enough to lead the world on a path of destruction. Water is an easy solvent, enabling most pollutants to dissolve in it easily and contaminate it. The most basic effect of water pollution is directly suffered by the organisms and vegetation that survive in water, including amphibians.
On a human level, several people die each day due to consumption of polluted and infected water. As per the Economist report dated each day over children die of diarrheal sickness in India and the numbers have only increased alarming in the last five years.
Water is polluted by both natural as well as man-made activities. Volcanic eruptions, earthquakes, Tsunamis etc are known to alter water and contaminate it, also affecting ecosystems that survive under water.
Sources of Water Pollution There are various classifications of water pollution. The two chief sources of water pollution can be seen as Point and Non Point. Point refer to the pollutants that belong to a single source.
An example of this would be emissions from factories into the water. Non Point on the other hand means pollutants emitted from multiple sources. Contaminated water after rains that has traveled through several regions may also be considered as a Non point source of pollution.
Causes of Water Pollution Let us now study the causes of water pollution. Industries produce huge amount of waste which contains toxic chemicals and pollutants which can cause air pollution and damage to us and our environment. They contain pollutants such as lead, mercury, sulphur, asbestos, nitrates and many other harmful chemicals.
Many industries do not have proper waste management system and drain the waste in the fresh water which goes into rivers, canals and later in to sea.
Sewage and waste water: The sewage and waste water that is produced by each household is chemically treated and released in to sea with fresh water.
The sewage water carries harmful bacteria and chemicals that can cause serious health problems. Pathogens are known as a common water pollutant; The sewers of cities house several pathogens and thereby diseases. Microorganisms in water are known to be causes of some very deadly diseases and become the breeding grounds for other creatures that act like carriers.
|Water Contamination| Other Uses of Water | Healthy Water | CDC||Dumping trash into water bodies Sewage water produced by households Burning of fossils fuels like coal and oil Chemical fertilizers Types of water pollution 1. Industries throw their wastes like fertilizers, waste water and sewage into river bodies.|
|Sources of Water Pollution||More than one third of all waterways are reported to be unsuitable for fishing or swimming because of pollution. Most contaminants are sewage and bacteria, fertilizer, toxic metals, oil and grease.|

These carriers inflict these diseases via various forms of contact onto an individual. A very common example of this process would be Malaria.
Mining is the process of crushing the rock and extracting coal and other minerals from underground. These elements when extracted in the raw form contains harmful chemicals and can increase the amount of toxic elements when mixed up with water which may result in health problems.
Mining activities emit several metal waste and sulphides from the rocks and is harmful for the water. The garbage produce by each household in the form of paper, aluminum, rubber, glass, plastic, food if collected and deposited into the sea in some countries.Pollution from dispersed sources is difficult to control, and, despite much progress in the building of modern sewage-treatment plants, dispersed sources continue to cause a large fraction of water pollution problems.
PREFACE Water Matters: research with a view to a practical application. In front of you is the seventh edition of Water Matters, the knowledge magazine of the journal H 2 O. You will find ten articles about a variety of subjects, written by Dutch water professionals on the basis of thorough research.
In , in the National Water Quality Inventory report to U.S. Congress, the states reported that agricultural nonpoint source (NPS) pollution is the leading cause of river and stream impairment and the second leading cause of impairment in lakes, ponds, and reservoirs.
Explains the different types of sources of water pollution. Water pollution is the contamination of water bodies (e.g.
lakes, rivers, oceans and groundwater). Water pollution affects plants and organisms living in these bodies of water; and, in almost all cases the effect is damaging not only to individual species and populations, but .
Nutrients, such as nitrogen and phosphorus, are essential for plant and animal growth and nourishment, but the overabundance of certain nutrients in water can cause a number of adverse health and ecological pfmlures.comen, in the forms of nitrate, nitrite, or ammonium, is a nutrient needed for plant growth.
About 78% of the air that we breathe is composed of nitrogen .
