The Effects Of Water Pollution On Environment And The Environment

Unsafe water supplies are often contaminated with infectious agents, toxic chemicals, and radiological hazards. In 2000, the World Health Organization and UNICEF identified some 2.4 billion people who did not have basic sanitation facilities, and 1.1 billion people without a safe drinking water supply. (Wagner, 2009) Some communities experienced diarrhea, caused by a variety of parasites, viruses, and bacteria that infect people as a result of contaminated drinking water or poor hygiene. In India, more than 500,000 children die from diarrhea every year. Like other tropical diseases, when diarrhea does not kill, it weakens, leaving people more susceptible to other infections, such as tuberculosis and HIV. (Whitman, 2008).

Excess pesticides can end up in the water supply due to runoff water or seepage through the soil.

When you think of problems in the world today, water pollution isn’t one that would normally come up. In fact it is one of the worst problems in the world today. Water pollution, by definition, is the contamination of streams, lakes, underground water, bays, or oceans by any substances harmful to living things. All living things contain water and most need water to survive, so water pollution is a big problem. If severe, the pollution can kill off birds, fish, and any animals that use the water source. In some cases even killing an entire species.

Leaching of pesticides, herbicides and other Argo-chemicals, these chemicals are the overriding causes of agricultural pollution owing to the numbers of invasive pests, weeds, and diseases. They're highly toxic and have the potential of remaining in the environment for ages. When it rains, these chemicals will leak

Chemicals harm the growth of plants and animals, chemicals can lead animals to death. Many of the water animals

Water pollution is when, “one or more substances have built up in the water to such an extent that they cause problems for animals and people” (Woodford). Water pollution is also bad for humans and animal’s health. Sewage, chemicals, radioactive waste, oil pollution, and plastic, are some causes for water pollution (Explain That Stuff). When water from rain runs off roofs and roads into rivers it carries away trash, toxic chemicals, dirt, and harmful organisms (NRDC Water). Some solutions to these are to throw things into the correct bin, use water wisely, and not throw chemicals, oil, paints, and medicine down the sink, drain, or toilet. Also plant lots of trees and have cities develop a sewage treatment plant to minimize pollution (eSchool Today). It’s important to protect our

By using these chemical pesticides on the plants, it causes dissolved oxygen depletion in the water, phytotoxicity to the plants, and poisons the animals (Environmental Effects of Pesticides). From the greediness of crop cultivation, millions of species of fish will disappear. These pesticides do not only get into the ocean by spraying it, they get into the ocean when small particles fly over from the drift of the wind. This is especially common at beaches where people spray chemicals on the grasses nearby to prevent other people from being bitten by insects. Not only do pesticides affect the oceans, but the plants as well. These pesticides cause phytotoxicity refers to plant injury. By using these chemical pesticides, it damages the plants, especially those genetically similar to weeds. They can progressively result in mutations little by little until eventually there will be a period of time where the plants now will be very different. Even though this is what is happening now, Hawthorne, an author from 200 years ago, also thought that scientists were being evil. In “Rappaccini’s Daughter,” when it states “Dost thou deem it misery to be endowed with marvellous gifts, which no power nor strength could avail an enemy?...Wouldst thou, then, have preferred the

The pesticides are not only poisonous to the insects and larger animals, but also to the people who live on the land. Another item that plays a big role in the pollution is the fertilizer used by the farmers, and that also enters the water systems. Not to mention it also destroys all of the other sensitive vegetation in the area. Once the fertilizer enters the water it makes the algae grow at increased rates while killing the organisms that feed on it. The final result is the algae overwhelming the other aquatic plants and life, while restricting water flow.

drug residues and sediments in the field, it will then eventually runoff into our streams, lakes, rivers. Which cause our water to be contaminated and affecting our food quality and living organisms in the water. I think it is good that we have a system to take control of our agriculture but we don’t realize how much it is hurting us and the environment around us. We are not the only ones who are affected by water pollution but also plants and animals who feeds out of these waters.

A major challenge and cause of serious medical issues in Sub-Saharan Africa is the lack of access to a clean water supply. There are 345 million people that lack access to water in Africa. Unfortunately, when water is available it is high in contamination. When wells are built and water sanitation facilities are developed, they cannot be maintained properly to due to limited financial resources. Water quality testing is not performed as often as necessary and the people are unaware that the water may not be safe to drink. Oftentimes, when a source of water has been provided, the quantity of water is often given more attention over the quality of. Lack of clean drinking is the leading cause of diarrheal diseases in Sub-Saharan Africa and causes 7.7% of deaths in Africa. Diarrhea is caused by numerous bacterial, viral and parasitic organisms most of which can be spread by contaminated water. The importance of diarrheal diseases has mostly been overlooked. Through UNICEF and the World Health Organization (WHO) there have been some accomplishments during the

The chemical pesticides used in farming affect the quality of water because of run off which then go into lakes or rivers. In chapter four, Carson concentrates on the water pollution caused by pesticides. The pollution can be unsafe for use and causes fish to die. An example used is a study done by the United States Fish and Wildlife Service in 1960 that showed that “our waters have become almost universally contaminated with insecticides.” (pg.41) The pesticides are especially threatening to groundwater which is an important source of drinking water for humans. Consequently, the chemicals in pesticides can cause cancer and other harm effects on our health. Another issue is that the pesticides in water and can mix with other chemicals and become a new chemical. Therefore, it can lead to the creation of an unknown chemical with harmful

Everyday pesticides are dumped into our environment. Over time most of the pesticides make thier way to a source of water, whether it's groundwater or a body of water. According to Lewis Regenstein author of "America the Poisoned" two thirds of the nation's lakes have serious pollution problems. 80% of 3,700 urban lakes in the United States are destroyed. More than 94 million residents could use these lakes for recreational use or for a source of water (169). Cincinnati's drinking water contains about 700 chemicals. 90% of them did not exist 20 years ago. The main sources of most of these chemical pollutants are municipal sewage, industrial discharges, and runoffs from farming areas. There are also several other chemicals in America's drinking water. Although hazardous, there are approximately 60 chemicals that are mixed into water in the process of treating it. Unlike rivers or lakes, underground supplies are not processed at treatment plants before being used by humans. "More than one hundred million of our citizens depend in a whole or in part on underground as sources of drinking water (Beck qtd. in Regenstein 172). Once groundwater becomes contaminated, there is usually no way to clean it.

Agricultural runoff is when rainwater washes pesticides, insecticides, fertilizer, animal manure and other farm products into the water and ground. Agricultural runoff can affect marine life because of excess nutrients running into the water, and it can also leak into the ground and affect water quality for drinking.

Water is a critical source that is utilized by most living things on Earth to support it ways of live. The usage of water ranges from basic household needs to agricultural purposes. Water is one of the resources on the Earth that is becoming more and more scarce and the water available for usage is being further contaminated by pollution causing sickness and death.(World Health Organization).Countries are experiencing droughts affecting the water supply needed to maintain irrigation, thermoelectric power, and public supply. The definition of water pollution is the result of when too many toxic materials are present, in which negatively impact the water to be unsafe for its intended purpose, which may be drinking to industrial processes

Drinking water quality was not a concern until the last century when the use of chemicals was greatly expanded. Chemicals are used to kill weeds, insects, and other pests. Chemicals are typically sprayed on an area and are designed not to harm the crop, grass, or other plants that you want to remain. This mass application procedure allows much-unutilized chemical to soak into the soil and eventually leach into the
