Water pollution consists of any physical or chemical change in water that adversely affects the health of and other organisms Sewage is the release of wastewater from drains or sewers for example : from toilets ,washing machines and showers. It also includes human wastes such as soap and detergents. Disease causing agent for example : bacteria, viruses, protozoa and parasitic worms are transmitted in sewage. Sediment pollution, primarily from soil erosion, increase water turbidity, thereby reducing photosynthetic productivity in the water. Inorganic plant and algal nutrients for example: nitrogen and phosphorus , contribute to enrichment . The fertilization of a body of water. Many organic compounds for example : pesticides ,pharmaceuticals, solvents and industrial chemical. These organic are quite toxic. Inorganic chemical also includes toxic such as lead and mercury. Radioactive Substance include the wastes from mining, refining, and using radioactive metals. Thermal pollution occurs when heated water, produced during many industrial, is released into waterways. Sewages supplies nutrients that contribute to eutrophication and a high biochemical oxygen demand .Eutrophication , the nutrient enrichment of lakes ,estuaries or slow moving streams results in high photosynthetic productivity and supporting an overpopulation of algae. Eutrophication also kills fishes and causes a decline in water quality as these algae dies and decomposed. Biochemical oxygen demand is the amount of oxygen needed by microorganisms to decompose biological wastes inti carbon dioxide such water and minerals. A large amount of sewage generates a high biochemical oxygen demand , which also lowers the lever of dissolved oxygen in the water. Most municipal water supplies are treated before used so that the water is safe to drink. Water is usually treated with aluminum sulfate to cause suspended particles to clump and settle out. Its also filtered through sand and disinfected by adding chlorine. There is concern that chlorine in drinking water creates health problem. So in the case UV includes radiation and zonation and their being developed. There are two types of tertiary treatment for wastewater such as primary and secondary. Primary treatment is treating wastewater by removing suspended and floating particales by mechanical processes. Secondary treatment is treating wastewater biological to decompose suspended organic material. Secondary treatment reduces the water’s biological oxygen demand. Primary treatment and secondary treatment generate primary and secondary sludge which also consist of the solids remaining after sewage treatment has been completed.…
Global Warming effects our everyday
lives and it occur cause of Air Pollution, Deforestation, and Human Activities. Global Warming occurs
everywhere and it doesn’t affect just the U.S but everywhere which is why we need to react fast and
make it stop.
Air Pollution is a major cause of Global Warming. Air pollution is bad as it can cause lung
irritation, burning eyes, coughing and chest tightness. Air pollution also affects the environment by
destroying the ozone layer resulting…
drinking the food that you ate last night. You could be drinking water or bathing in water that is not the purist water possible, because of pollution humans are producing. The world’s ecosystems are becoming unbalanced and unhealthy because of the pollution that humans are producing.
Much of our drinking water comes from underground aquifers and many chemicals are in that water because chemicals sink underground into that water. The chemicals can cause a large amount of problems, like dead zones…

This website gives you very useful data on water pollution, collected by the organization called the GLIN. The Great Lakes Information Network (GLIN) is a partnership that provides a place online for people to find information relating to the International Great Lakes-St. Lawrence…
quality water talked about in flow is due to pesticides, pharmaceuticals and previous wars that pollute our water. In one of the developing countries, Palo Alto, citizens have no choice to drink the polluted water as they can’t afford it. The result is that one in ten children are expected to die before the age of 5. This was a common problem in all of the countries shown in the documentary. Companies would demand too high of a price for water, forcing people to give up their houses as water was more…
sources of protein, energy, minerals and other products of use the world over and the rolling of the sea across the planet creates over half our oxygen, drives weather systems and natural flows of energy and nutrients around the world, transports water masses many times greater than all the rivers on land combined and keeps the Earth habitable.
Without the global ocean there would be no life on Earth.
It is gravely worrying, then, that we are damaging the oceans on a scale that is unimaginable…
Issue Research Paper
Water pollution has been viewed by many as a leading worldwide cause of deaths and diseases, accounting for more than 14,000 deaths daily. About 580 people in India die of water pollution every day, while 90% of China's cities suffer from some degree of water pollution. Almost 500 million people lack access to safe drinking water in China.
Developing countries are not the only ones with water pollution problems. Developed…
What are the main types of pollution, and what can be done to prevent pollution or to reduce its effects?
Media coverage of pollution of our air and water and land often shocks us. Environmental research has given us valuable information about the different aspects of pollution, and it behoves us to be aware of our often inadvertent interference with the environment so that we will be able to take intelligent and appropriate steps to avert a possible catastrophe -- our own destruction through…

Air and Water Pollution
Pollution is the introduction of harmful contaminants released into the environment (Green student, 2013). Air and water pollution can cause numerous health issues in society ranging from respiratory problems to cancer. It not only effects humans it also impacts every organism on the planet. Pollution can reduce the overall productivity of crops, which when combines with…

pollution is the contamination of water bodies such as lakes, rivers, oceans
and groundwater. This form of environmental littering occurs when pollutants are directly
or indirectly discharged into water bodies without adequate treatment to remove harmful
compounds. Water pollution is a major global problem which requires ongoing evaluation
and consideration. Each day more and more bodies of water are polluted by factors such as
old sewer systems…
Causes of Water Pollution and Cures to Stop it Now
Nature plays a role when it comes to toxins like mercury and other heavy metals, but humans are among the major causes of water pollution. We have always treated the planet with a certain level of disregard, as if we simply thought that nothing we could do would be of any consequence. Now though, the way we have treated our environment is coming back to haunt us.
Since the beginning of the industrial revolution we have unleashed 80,000 chemical…
