Pollution not only affects human life but also the rest of the animal kingdom and the ecosystem in general. It can result in the shortage of water that can be used for human consumption as well as for agricultural purposes Agarwal A consequence of water pollution also includes the destruction of aquatic life which can also impact the economy of various countries because aquatic animals such as fish form an important part of the food, and import and export industries.
Therefore, water pollution is indeed a very serious concern because it not only has an impact on health and but also can have negative effects on various industries and agriculture. It is therefore highly important to devise methods to reduce the level of water pollution that we are currently facing. Causes, Effects and Control.

The surface water gets polluted by the run of water from agricultural Fields containing pesticides and fertilizers, soil particles, waste chemicals from industries and sewage from cities and rural areas. However, the surface water can be purified and reused. Water is the most important constituent of the life support system because on one hand it is vital for the maintenance of all forms of life and on the other it helps in the movement, circulation and cycling of nutrients in the biosphere.
It may be noted that only one per cent of the total quantity of water of the hydrosphere is available to human beings and other biotic communities from various sources such as ground water, rivers, lakes, atmosphere and biological systems. The results of water pollution are evident whether measured by harms to the living resources or hazards to human health or reduction of immunities.
Anyway, water pollution is a global problem affecting both developed and developing countries. Depending upon the specificity of waste discharge, the water pollution sources are categorised as: Point sources are those which discharge pollutants from some specific location such as pipeline, ditches and sewers into water bodies. The pollutants from point sources are of definite identity with almost a fixed volume and composition. The level of pollution can be controlled by suitable experimental modulation.
Non-point sources of water pollution are widely scattered and discharge pollutants over larger areas. Water pollutants are divided into the following classes on the basis of pollutant sources: The natural pollutants include volcanic dusts, sediments due to weathering and erosion, debris caused by landslide, decayed and decomposed organic matter etc.
Such pollutants are also known as organic pollutants, e. These pollutants cannot be degraded by biological means. These are also known as inorganic pollutants, e. On the basis of sources and storage of water, water pollution nay be divided into the following categories: The composition of ground water is given in Table 5. These extraneous materials wastes are constantly added into ground water reservoirs at an alarming rate causing the pollution of ground water.
Once the ground water is polluted, it is difficult to restore the original water quality of the aquifer. The hazardous effluents released from industries, contain toxic heavy metals, ions and a number of organic and inorganic species. These contaminate the ground water and severely pollute it. Besides agricultural processing wastes and animal wastes are also significantly polluting ground water.
The primary factors responsible for deteriorating the ground water quality are pathogenic organisms, oxygen demand, nutrients and solids from domestic wastes. Rapid urbanisation releases a lot of effluents which contains large concentration of oils, greases, nutrients, heavy metals and detergents. The detergents being soluble can pass through the soil and pollute ground water. Soluble effluents can easily pass through and pollute the ground water.
The extent of pollution is more prominent in sandy soils and humid regions having high water table condition. The level of pollutants in ground water can be minimised by the following manner: River water is one of the forms of surface water. The river water gets polluted and causes a number of potential hazards to living organisms.
Water pollution is one of the world's worst forms of pollution. For example, take a look at a glass of water. It may appear clear, but there are really millions of microscopic pollutants floating in it. Approximately 70% of the earth's surface are covered by water; water is a very dynamic system 3/5(10).
Water Pollution Essay 1 ( words) Water pollution has become a continuous increasing problem on the earth which is affecting the human and animal lives in all aspects. Water pollution is the contamination of drinking water by the poisonous pollutants generated by the human activities.

Essay on Water Pollution Water covers two-thirds of the Earth’s surface, with over 97% present in the oceans and less than 1% in freshwater streams and lakes. Water is also present in the atmosphere in solid form in the polar icecaps and as groundwater in aquifers (water-bearing rocks) deep underground.
Pollution itself is when a substance or energy is introduced into the soil, air, or water in a concentrate. Pollution comes in many forms; agricultural, urban runoff, industrial, sedimentary, animal wastes, and leeching from landfills/septic systems just to name a few. Water pollution, like other types of pollution result when an overwhelming amount of waste comes from different sources of pollutant which harmfully disrupts the balance of the ecosystem; consequently, the waste cannot be destroyed or cleaned up as quickly as produced which results in many disadvantageous to humans and animals, as well as .
