Stop Water pollution

Water pollution
Water is one of the most abundant compounds on earth. About 75% of the Earth’s surface is covered with water. The three main types of water sources are:-
Surface water
Ground water
Salty water
Unfortunately, we have been constantly polluting our rivers, seas, and other water bodies. Every year, more than 8,00,000 people around the world, die from water-borne illnesses.An estimated 700 million Indians have no access to a proper toilet, and 1,000 Indian children die of diarrhea sickness every day. Some 90% of China's cities suffer from some degree of water pollution, and nearly 500 million people lack access to safe drinking water.

The pollution of rivers and streams with chemical contaminants has become one of the most curtail environmental problems within the 20th century. Waterborne chemical pollution entering rivers and streams cause tremendous amounts of destruction.

The causes of water pollution

Sewage and wastewater

Domestic households, industrial and agricultural practices produce wastewater that can cause pollution of many lakes and rivers. Sewage is the used for waste water that often contains feces, urine and laundry waste. Sewage is mainly biodegradable and most of it is broken down in the environment. Water pollution is the addition of any substance that has a negative effect on water or the living things that depend on water. The substances that cause water pollution are called pollutants.

Purification of water
Purification of water involves physical, biological and chemical processes such as:-
1.Filtration
2.Sedimentation
3.Chlorination
4.Slow sand filters
5.Activated Sludge
6.Flocculation

The presence of a substance in the environment that because of its chemical composition or quantity, prevents the functioning of natural processes and produces undesirable environmental and (human) health effects.

How to prevent
Conserve water by turning off you running water at your home
Do not throw litter into sinks and toilets
Help clean up litter in water filled areas
Contain and compost yard waste

A natural and beautiful method of doing this is being used in many places. They are called rain gardens. They are specifically designed with plants that will absorb water that otherwise would have runoff into waterways. This measure also stops contaminants that may have been washed into those waterways.
