Causes of water pollution

Why is pollution issue so important? What is the most polluted water? Industries produce a huge amount of waste which contains toxic chemicals. The sewage and wastewater that is produced by each household is chemically. Mining is the process of crushing the.

It occurs when foreign harmful materials like chemicals, waste matter, or contaminated substances are directly or indirectly discharged into water bodies.

Pollution caused by landfills, sewage, animal waste and industrial waste like that from slaughterhouses and food processing factories is called microbial pollution. This pollution in caused by microorganisms that occur naturally. These include bacteria, viruses (like E.coli and Giardia) and protozoa diseases like cholera. Dumping solid wastes and littering by humans in rivers, lakes and oceans.

Causes of Water Pollution Sewage from domestic households, factories and commercial buildings Sewage. Industrial waste from factories, which use freshwater to carry waste from the plant into rivers,. The causes of water pollution vary and may be both natural and anthropogenic. Atmospheric Atmospheric deposition is the pollution of water bodies caused by air pollution.

Each time the air is polluted with sulphur dioxide and nitrogen oxide , they mix with water particles in the air and form a toxic substance.

This falls as acid rain to the ground and gets washed into water bodies. Chemicals released by smokestacks (chimneys) can enter the atmosphere and then fall back to earth as rain, entering seas, rivers, and lakes and causing water pollution. This dearth of oxygen, known as eutrophication, suffocates plants and animals and can create “ dead zones ,”. Accidental water pollution can arise from many sources (such as burst pipes and tanks , major leaks , fires and oil spills ) and can cause varying degrees of damage, depending on the quantity, toxicity and persistence of the pollutant, and the size and adaptability of the water body.

Contaminants may include organic and inorganic substances. Elevated temperatures can also lead to polluted water. A common cause of thermal pollution is the use of water as a coolant by power plants and industrial manufacturers. The human being is the main responsible for water pollution.

The main cause of this type of pollution is from the gradual drips and leaks from cars, machinery, boats, and fueling stations that get carried by rain water into the nearest water source and rivers. People began to build houses, roads, and big industries. Thereafter, there is a physical disturbance of the land and factories began to dump their chemical wastes in the bodies of water. Big factories flush down waste products in the water, and this is one of the major causes of ocean pollution.

This article throws light upon the twelve main causes of water pollution. Domestic or Sanitary Sewage 3. Other Forms of Pollution. The main causes of water pollution are most often man made and caused by increasing industrialization and human activities.

Mostly the water bodies get polluted with municipal, industrial and agricultural waste and their unplanned leaking, run off, dumping and disposal. Polluted water can lead to sickness, disease, infections, deformities. Once water becomes polluted it can affect people and animals either.

Urbanization : Rapid urbanization in the world during the recent decades has given rise. Agricultural runoff and improper agricultural practices: Traces of. Here are the few major causes of water pollution : Sewage And Waste Water : Sewage, garbage and liquid waste of households, agricultural lands and factories are discharged into lakes and rivers.

These wastes contain harmful chemicals and toxins which make the water poisonous for aquatic animals and plants.
