Surface Pollution And Water Pollution

It is possible for any creature to live without water, and it is difficult even to perceive of life without water. The water is the main content of our body, especially the brain. In addition, it cover more than 70% of the earth.

The quality of the water that we want depends on the end use of this water. For example, drinking water need to be in the highest quality , un like agricultural and industrial needs.

That means polluted water is a level of very low water quality, which can not be used for drinking.

Unfortunately, some countries have no enough fresh water, so they have no other choices to drinking polluted water. Thus, people in those countries got illness from the water they drink.

Definition of water and water pollution

Water pollution is any physically or chemically change in water .in a direct or indirect way , affect negatively in living creature , human being and organisms , which let water un

2.2. types

Although interrelated, surface water and groundwater have often been studied and managed as a separate resources surface water leak through the soil and rocks in the mount and become ground water . Equally, ground water feed surface water when the ground water gets enough .Groundwater pollution is much less obvious than surface-water pollution, but is no less of a problem. There are two different ways in which surface pollution can occur based on their causes .

2.2.1 Point sources

Point sources refer to toxins –contaminants- that go to the waterway from a single location , identifiable source , such as a discharge pipe attached to a factory . so the examples in this category of sources contain discharges from :

1- Sewages treatment plant .

2- Factories, or a city storm drain.

3- A spill from an oil tanker creates an oil slick that can affect a vast area of the ocean.

This came from the CWA definition of the point source was amended in 1987 to include municipal storm sewer systems, as well as industrial storm water, such as from construction

Each year, the world generates perhaps 5–10 billion tons of industrial waste, much of which is pumped untreated into rivers, oceans, and other waterways. [8] In the United States alone, around 400,000 factories take clean water from rivers, and many pump polluted waters back in their place. However, there have been major improvements in wastewater treatment recently. Since 1970, in the United States, the Environmental Protection Agency (EPA) has invested about $70 billion in improving water treatment plants that, as of 2015, serve around 88 percent of the US population (compared to just 69 percent in
