get mixed in water and if the toxic elements are in large quantity then optimal concentration then it will pollute water. 1.3.6. Thermal sources of water pollution: Thermal pollution is generated by power plants. Industrial sources such as pulp and paper mills, petroleum refineries, chemical plants. Warm water from these industries domestic areas directly discharged into the rivers, lakes and other water bodies.
1. Introduction The pollution of surface water has brought so much frustration over the past years nationally and globally. Surface water pollution occurs when the quality of water degrade to an extent that it becomes uneasy to use due to the entering of harmful substances into the water systems. When surface water is polluted the environment is affected as a whole. Aquatic species such as plants and fish are threatened by poor water conditions (Botkin, D.B., 2014).
Direct sources of water pollution include runoff, industrial waste, sewage, and human waste. Indirect sources include air pollution and sediment from construction sites. Industrial waste can lead to air pollution, which can ultimately lead to the pollution of water. This is also called atmospheric pollution. Atmospheric pollution is caused by pollutants such as smoke from factories entering the atmosphere and being carried to waterways.
The cause of water contamination, those chemicals, have several sources. The first source is the domestic sewage. It contains only 0.1 percent of pollutants, and 99.9 percent of water. Although it seems that the domestic sewage is somewhat harmless, the 0.1 percent of pollutants can pose a large risk on water body. The pollutants mainly comes from detergent, sanitary sewage, and waste.
Content. Definition of water pollution. Water pollution is defined as the water contamination due to the direct or indirect pollutant that were discharge into river and contamination of the chemical that was not properly treated to remove harmful compound. Factors that cause water pollutions. There are several factors that causes the water pollution such as the non-point source, point source, rubbish dumping, industrial waste, and ballast water tank.
Over 780 million people are without access to clean drinking water, and around 2.5 billion people do not have access to an adequate sanitation facility (Bradford). There are two primary ways in which water pollution is caused. The first way consists of objects such as trash from a landfill or parts of a boat which have fallen into the water. The other cause is due to fertilizers and other chemicals being spilled into the water ("Pollution"). Once enough pollutants fill the water, it becomes likely for it to become contaminated with dangerous pathogens, which survive on the pollutants and can be dangerous to the wildlife.

Water pollution is a huge problem these days and human activity is the main effect. People need to start taking action in what they do and start protecting our bodies of water. Some people don’t realize when pollution is being caused because they don’t realize what they do every day, causes it. Driving cars, using fertilizers, not cleaning septic tanks, and coal-fired power plants are some examples on what causes water pollution.
Water pollution is a major global problem which requires ongoing evaluation and revision of water resource policy at all levels (international down to individual aquifers and wells). It has been suggested that water pollution is the leading worldwide cause of deaths and diseases, and that it accounts for the deaths of more than 14,000 people daily.  An estimated 580 people in India die of water pollution related illness every day.  About 90 percent of the water in the cities of China is polluted.  As of 2007, half a billion Chinese had no access to safe drinking water.
As industries dump industrial waste into our rivers, creeks, lakes, oceans and other bodies of water it causes an imbalance in the water leading to the severe death and contamination of aquatic species. In fact, the main problem caused by water pollution is that it kills organisms that depend on these water bodies. Irreparable damage to the water bodies are caused by oil spills in the ocean and spraying of insecticides and pesticides like DDT on our plants, as well as industrial waste and illegal
It causes many problems with the living plants and animals in the water. Sewage can cause water pollution along with the toxic chemicals from Industrial business. According to studies, it is only a matter of time before spread of contaminated fish more, increase the number of deaths and spread of illnesses such as hepatitis, typhoid, and cholera become the main concern for humanity and thus fast and serious reactions are required. Unless an immediate action to address water pollution and to find a solution for it is taken, these consequences will continue to intensify, grow ever more costly, and increasingly affect the entire planet including families, children, animals and
