Water pollution was really first noticed around 1980 when an oil spill called Exxon Valdez showed many horrible effects of water pollution. Oil spills are just one of the causes of water pollution. Every year, 14 billion pounds of sewage, sludge, and garbage are dumped into the world's oceans. The problem of ocean pollution is that it affects every nation around the world. This is especially true because water is able to transport pollution from one location to another. As the world has become more industrialized and as we are creating an increasing amount of pollution, the problem of water pollution has intensified and is on the rise. In addition, the fact that millions of people live along coastlines and near rivers means that these bodies of water are likely candidates for heavy and destructive pollution. It is difficult to determine what our oceans will look like in the future or just how damaged they will be by pollution.

Microbiological water pollution

There are many types of water pollution such as microbiological water pollution and chemical water pollution.

Microbiological water pollution is usually a natural form of water pollution caused by microorganisms.

Many types of microorganisms live in water and cause illnesses in fish, land animals and humans. These Microorganisms include:

• Bacteria
• Viruses
• Protozoa

Serious diseases such as cholera are caused by microorganisms that live in water. These diseases usually affect the health of people in poorer countries, as they do not have the facilities to treat polluted water.

Chemical water pollution

Industrial and agricultural work involves the use of many different chemicals that can run-off into water and pollute it.

• Metals and solvents from industrial work can pollute rivers and lakes. These are poisonous to many forms of aquatic life and may slow their development, make them infertile or even result in death.

• Pesticides are used in farming to control weeds, insects and fungi. Run-offs of these pesticides can cause water pollution and poison aquatic life. Subsequently, birds, humans and other animals may be poisoned if they eat infected fish.

• Petroleum is another form of chemical pollutant that usually contaminates water through oil spills when a ship ruptures. Oil spills usually have only a localised effect on wildlife but can spread for miles. The oil can cause the death of many fish and stick to the feathers of seabirds causing them to lose the ability to fly.

Water pollution

L'eau pullution a commencé environ 1980 lorsqu'un déversement de pétrole appelée Exxon Valdez a montré beaucoup horibles effet de l'eau pullution. pétrole est juste une des nombreuses façons de polluer l'eau. Chaque année 14 milliards de livres d'eaux usées,boues, et ordures sont déversés dans les océans du monde. Le problème de pollution c'est qu'il touche toutes les nations dans le monde entier. Cela est particulièrement vrai puisque l'eau est en mesure de transport pullution d'un endroit à l'autre. Comme le monde a pays industrialisés et sa pollution a augmenté, Le problème de pollution des eaux a intensifié. Des millions de personnes vivent le long littoraux et proche des rivières qui signifie que Ces organes de l'eau sont probablement candidats pour de lourds et destructrices pullution . Il est difficile de savoir maintenant ce que nos océans examinera à l'avenir, à quel point endommagé ils seront par la pollution.

Microbiological water pollution

Il existe de nombreux types de pollution des eaux, tels que la pollution des eaux microbiologiques et chimiques la pollution.

Microbiologiques la pollution des eaux est habituellement une forme naturelle de la pollution des eaux causée par micro-organismes.

De nombreux types de micro-organismes vivent dans l'eau et cause poissons, les animaux terrestres et l'homme à devenir malades.

Micro-organismes tels que:
• Bacteria
• Viruses
• Protozoa

Les maladies graves comme le choléra proviennent de microorganismes qui vivent dans l'eau. Ces maladies affectent la santé des gens dans les pays pauvres, comme ils n'avons pas les installations pour traiter l'eau polluée.

Chemical water pollution

Industriel et le travail agricole implique l'utilisation de différents produits chimiques qui peuvent exécuter-off dans l'eau et de polluer.

• Métaux et les solvants de travail industriel peut polluer les rivières et lacs. Ces sont toxiques pour de nombreuses formes de la vie aquatique et peuvent ralentir leur développement, les rendre stériles ou même entraîner la mort.

• Les pesticides sont utilisés dans l'agriculture à contrôler les mauvaises herbes, les insectes et des champignons. Lancez-pied de ces pesticides peuvent causer la pollution des eaux et d'empoisonner la vie aquatique. Par la suite, d'oiseaux, les humains et d'autres animaux peuvent être empoisonné s'ils mangent poisson infecté.

• Le pétrole est une autre forme d'armes chimiques polluant qu'habituellement contamine eau par les déversements de pétrole lorsqu'un navire ruptures. Les déversements de pétrole ont généralement qu'une localisée affecte sur la faune mais peut se propager des milles. L'huile peut causer la mort de nombreuses espèces de poissons et bâton à les plumes des oiseaux de mer qui les causent à perdre la capacité de voler.

Water pollution

Fresh water, salt water from rain or groundwater can be contaminated by materials that can make it harmful. Such pollution is the cause of various diseases and can seriously affect health.
First, bodies of water can be contaminated by organic matter. Thus, chlorides and nitrates in human and animal waste can contaminate the groundwater from shallow wells. Second, the pollution of ground water tables can be caused by overexploitation of the soil. Fertilizers, pesticides and insecticides are all products that can seep into the soil or runoff into lakes, rivers and the sea.

Water pollution is the contamination of water bodies (lakes, rivers, oceans and groundwater). The pollution of water can be in various forms: chemical, bacteriological, and also thermal pollution of water bodies that are fresh, brackish, salty groundwater or surface water. Polluted water may even be rain or dew, snow, or polar ice. The major types of water pollution are municipal, industrial, and agricultural water pollution. Municipal water pollution consists of waste water from homes and commercial establishments. Agriculture, commercial livestock and poultry farming are sources of pollution because they throw many organic and inorganic pollutants into surface water and groundwater. Waste materials such as acids, alkalis, toxic metals, oil, grease, dyes, pesticides and even radioactive materials are poured into the water bodies by many industrial units. In the United States, the industrial wastes cause more than half of the total water pollution.

What are the causes of water pollution? This question has no simple answer. Water pollution can be defined as any harmful effect on water bodies resulting from human activity. This can include pollution of rivers, lakes, oceans, and ground water pollution. The causes of pollution in the water are virtually endless. Manufacturing plants are major causes of water pollution as wastes from these plants are ejected into bodies of fresh water, which carry away waste that can contain phosphates, nitrates, lead, mercury and other harmful and toxic substances. Even the hot water that factories often discharge can raise the temperature and change the chemistry of bodies of water, causing what’s called “thermal pollution.” Construction byproducts are another major cause of water pollution: cement, metals, plastics and lubricants are the usual culprits. In addition to large industries, individual consumers round up the list of causes of water pollution. We pour our waste chemicals and detergents into our rivers. Small boats and large ships alike are responsible for spilling oil into our seas and oceans and dropping untreated sewage into the water. These pollutants are carried by waves to even the most remote parts of our oceans.

This is the way I see water pollution, Pauline

Water pollution is caused by several factors:
There are industrial wastes. Some industries eject their wastes into water bodies.
There are also wastes from farming. Pesticides, fertilizers and other chemical products used in farming often seep into streams and groundwater, which then flow into rivers.
People pollute water as well. There are some people who throw waste into rivers.
