Causes And Effects Of Water Pollution

Water is probably the most important resource we as people have. Humans can survive without food for several weeks, but without water we would die in less than a week. On a slightly less dramatic note, millions of liters of water are needed every day worldwide for washing, irrigating crops, and cooling industrial processes, not to mention leisure industries such as swimming pools and water-sports centers. Despite our dependence on water, we use it as a dumping ground for all sorts of waste, and do very little to protect the water supplies we have.

Pollution is also a problem with the impact of the ecosystem. People also can cause pollution which impacts the ecosystem. When people put DDT on their grass it gets into the Great Lakes ecosystem. The runoff carries the DDT into the Great Lakes water then it gets into the Phytoplankton,

Water pollution has a negative long term effect on aquatic life, humans, and our environment. The effects of water pollution on one of these things is like a domino reaction, where they will all be eventually affected if one is affected. It is estimated that there are 2 tons of industrial waste that is disposed into the ocean every day. Humans are the only contributors to water pollution, therefore what we do will directly impact the environment. Manure, fertilizer, and industrial waste, which reach the ocean via runoffs, or when they get into sewages.

Water Pollution isn’t going to be stopped by regulations, scientists are going to have to come up with ways to within the environment to stop it. In order to get rid of surface water pollution, scientists have come up with ways to reduce it. Recent research from the University of Sinaloa has found a plant that is used to get rid of some of the water pollution. Typha domingensis is reducing pollution from bacteria from mammals by “ninety-eight percent” (“Common Weed”). This weed is quite tall and can be found in either shallow or deep water. In a study, the plant found nearly several types of bacteria that was causing pollution in the water (“Common Weed”). This plant is just a start to stop water pollution or at least contain it. Scientists have come up with new systems that can remove water pollutants from fields. Laura Christianson is an expert in what kind of woodchips would react with the field pollutants (“New System”). The woodchips help get rid of the nitrate in fields. They woodchips can consume the nitrate which is then removed from the water. To get rid of the phosphorus, they created a system called a p-filter (“New System”). There are two different types of filters, acid mine drainage treatment residual and steel slag (“New System). The acid mine drainage also called MDR for short, removed roughly “eighty to ninety percent of phosphorus” (“New System”). The MDR filter is by far more productive in removing phosphorus compared to the steel slag. The steel slag is

Water contamination kills all different types of animals every year. Oil spills in Alaska near the Waterfront caused over thousands of otters to die and many other animals were affected. Sooner or later water pollution will affect the animals living in the water by causing no life in the Ocean, lakes, and rivers where most organisms survive. All that throwing away of waste into the water will cause the water creatures to perish and there will not be any place endurable where people can swim and enjoy themselves.

Throughout the years in the U.S and other countries, pollution has been a major conflict for people, plants, and animals. However, water pollution is considered to be one of the largest killers in the world. Every year, tons of waste and garbage are dumped into the oceans, destroying the ecosystem and disrupting the food chain. Due to the effects of water pollution, and any kind of pollution, the ecosystem will be affected and damage the world we live in.

The volume of Water on Earth is around 1.4 billion km and 70% of the Earth is shrouded in water. In the meantime 70% of modern waste is dumped into water bodies which drives us to water contamination. So what is water contamination or water pollution? (Conserve Energy Future, 2017) (1). Water contamination or water pollution is described as the closeness in groundwater of harmful chemicals and natural and organic specialists that outperform what is ordinarily found in the water and may speak to a hazard to human prosperity and also the earth. In addition, it might contain chemicals brought into the water as a result of the human exercises. (Woodford, 2017) (2). Primary drivers of water pollution are solid & domestic wastes, sewage pollution, petroleum pollution, toxic chemicals and other human activities that lead to contamination.

Pollutants are impacting aquatic organisms distributed by daily human activities and natural occurrences. An extensive amount of pollutants such as pesticides, heavy metals, and hydrocarbons can result in direct significant damage, e.g. death. However lower levels of these harmful substances can be stored in an organism and increase as it continues and follows up the food chain, a process called biomagnification or bioaccumulation, having the greatest effect on the top predator of that food chain. A common result of the pollutants can lead to stress, changing of the immune system, inhibit lysozyme activity, damage gills, metabolism, and growth. Other factors include an excessive amount of nutrients in the environment. Nitrogen can make its way into aquatic ecosystems when there is an increase in nitrous oxide in the air, allowing eutrophication. Algae and bacteria feed off the nitrogen, so a high number of these organisms appear and use oxygen around them as the feed, causing hypoxic zones, or dead zones. Acidification, an increase in the ecosystem’s pH acidity from acid rain, which occurs from an increase in CO2 from air pollution. Aquatic organisms have a range of tolerance, and water with high acidic pH will lead the organism out of the range of tolerance, resulting in stress of the organism, and eventually death. Further studies are being pursuited to see larger impacts of globalized pollution on aquatic species and their ecosystems.

Water pollution is a major global problem which is the pollution of water (seas, lakes, rivers, swamps)... The pollution is produced by storm/rainwater, sewage water and industrial waste. In developing countries, 70% of the waste dumped into waters come from industries. More than 80% of sewage water from sewage treatment plants pollutes water without being treated first! 43% of America's rivers and lakes are too polluted for fishing, swimming, or aquatic life. 1.2 trillion gallons of sewage water and industrial waste are released into US waters every year. Water pollution can also be in the form of solid waste.

Water quality is a necessity to human life and all other species. According to Turk, J., & Bensel, T. (2014) the Clean Water Act The primary federal law in the United States governing water pollution, whose purpose is to "restore and maintain the chemical, physical, and biological integrity of the nation 's waters (Turk, J., & Bensel, T. 2014) According to Water Quality and Water-Related Disease “The global public health impact of water contamination is significant for many reasons: (1) safe drinking water is vital for human survival to prevent dehydration; (2) water is essential for basic hygiene and modern sanitation methods, including wastewater treatment; (3) water use is key to every sector of an industrialized, transitional, and

Water is possibly among the most integral resources in the world. Water is one of the main resource for human development, it is even one of the major resources for agriculture, transportation and industrialisation. According to USGC (2015) about 70 percent of the earth is covered with water and from that only 2.5% is fresh water.Though water is an integral part of human life many people do not have access to it. The water (2015) claims that 663 million people or about 1 in 10 people in the world do not have access to fresh water. Industrialisation has aggravated water pollution and that has decreased the amount of freshwater available, one such example of a polluted fresh water river is the Chao Phraya River in Thailand (Greenpeace,2015). As freshwater bodies are becoming more scarce and expensive, fresh water should be provided in the most feasible way possible. This report will illustrate Desalination and Cloud seeding as the two techniques for providing fresh water in the arid regions of the world. Firstly, this report will look at the present situation of arid regions. Next, this report will examine the requirements needed for the techniques such as monetary and environmental requirements. Finally, comparisons would be made between the options and recommendations would be given.

Throughout history humans have been polluting this earth without even knowing it; so far managing to dump over five trillion pieces of trash into the oceans, which is almost three hundred thousand tons of garbage. This harmful act is creating hazardous effects on the environment, killing over fourteen million birds, and one hundred thousand sea mammals. The environment is coming back for revenge on humans by contaminating drinking water. The quality of drinking water is getting significantly worse for humans compared to what it was one hundred years ago Where the industrial revolution created new sources of water pollution, resulting in the clean water act of nineteen forty eight. This was the first law to regulate pollution, and set the

Water pollution affects plants and organisms living in these bodies of water; and, in almost all cases the effect is damaging not only to individual species and populations, but also to the natural biological communities.

70 % of our Earth surface is covered by water and almost 60% of the human body contain water for nutrient transportation. The unique characteristic of water is water molecule is the only substance in this Earth that exist in all three physical states of matter which are solid, liquid and gas. All human beings need water to survive. The national development over the years cause the rate of water pollution increased. According to Gebre & Rooijen (2009) water pollution can be considered as a sign that derives from economic growth and is a common phenomenon in urbanized cities in developing countries. In general, there are three main issues that related to water pollution which are the causes, effects and the way to decrease this problem.
