What is the water pollution?

Water pollution occurs when harmful substances—often chemicals or microorganisms—contaminate a stream, river, lake, ocean, aquifer, or other body of water, degrading water quality and rendering it toxic to humans or the environment. This problem of water pollution is getting harmful for our health. Unsafe water kills more people each year than war and all other forms of violence. Meanwhile, our drinkable water sources are finite: Less than 1 percent of the earth’s freshwater is actually accessible to us. Without prevention action, the challenges will only increase by 2050, when global demand for freshwater is expected to be one-third greater than it is now.

what it caused by?

Toxic and Radioactive substance

The water is polluted by toxic substances such as: Radioactive substance is generated by nuclear power plants, uranium and also by hospitals that use radioactive materials

what it caused by?

Oil pollution and Waste of water

-agriculture is the main cause of contamination of rivers and Aquifers, because when it rains waste pour substance (such a viruses into waterways) used and waste water that come from our shower, sinks and also rain water, which occurs when rain carries oil and grease into waterways -Oil Pollution which is increasing more and more today also due to the petrol leaking from the machines, but in marine environments the pollution comes from the factomes.

What it causes?

How it is dengerous for the human...

The consequences of the water pollution are the alteration of the environmental balance, due to the circulation of viruses and bacteria, both the animal and vegetable word, the ingestion of dangerous substances which can lead to development of serious disorder and pathologies. Pollution water can affect human health and contain of toxic and harmful chemical substances, the proliferation bacteria responsible for diarrhea, hepatitis and cholera

what it causes?

...but not only the human.

Marine pollution is one of the most urgent emergencies to deal with. in the last century the sea has become an immense landfill where all sorts of waste ends up, from industrial waste to plastic bottles, up to harmful substances used in agriculture. The effects of plastic pollution are beaches cluttered with debris, marine fauna that is fearfully decreasing and the appearance of harmful substances in fish flesh.Every year the list of whales, turtles or seabirds that die from suffocation or from gastrointestinal blockage due to the ingestion of plastic objects, or that are trapped there, is growing.

Kind of water pollution

Point source pollution: When contamination originates from a single source. Examples include wastewater discharged legally or illegally by a manufacturer, oil refinery, as well as contamination from chemical and oil spills, and illegal dumping. Nonpoint pollutiom: Nonpoint source pollution is when contamination derived from diffuse sources. Nonpoint source pollution is the leading cause of water pollution in U.S.A waters, but it’s difficult to regulate, since there’s no single, identifiable reason. Transboundary Pollution:Transboundary pollution is the result of contaminated water from one country spilling into the waters of another. Contamination can result from a disaster—like an oil spill—or the slow, downriver creep of industrial, agricultural, or municipal discharge.

How stop the water pollution

We are all responsible to some extent for today's pollution problem.Fortunately there are some simple ways you can prevent water contamination. Reduce your plastic consumption or recycle plastic. Properly dispose of chemical detergents, oils, etc. down the drain. Keep the car so that it doesn't lose oil. If you have a yard, avoid applying pesticides and herbicides.
