Only about 1% of all of the water that is on Earth is considered to be surface water such as lakes and rivers, however, the usable freshwater to us humans is only about .003% which we generally use for drinking, bathing, agriculture, or industry purposes. Unfortunately, pollution is reducing our few water resources even further on a global scale albeit mostly in developed countries. The United Nations have assessed the situation well in that, “Declining water quality has become a global issue of concern as human populations grow, industrial and agricultural activities expand, and climate change threatens to cause major alterations to the hydrological cycle”(Decade). This threat to our planet is mainly anthropological and has been growing …show more content…
Water pollution can be distributed from either a point or a non-point source. A point source is typically pollution that comes from one single location and is easier to identify, such as from a pipe, municipal WWTP discharge, a factory, or a ditch. A non-point source is categorized as pollution that has come from multiple sites over very large areas and are quite difficult to trace back and identify accurately. Some examples would be oil from the many streets of a city, different pesticides and fertilizer runoff from certain farms, some forest runoff, etc. There are three varied types of surface water pollution. One type is biological pollution which comes from disease causing organisms like bacteria. Another is chemical pollution which is either natural like nutrient pollution or artificial such as from fertilizers, pesticides, and pharmaceuticals. There is also physical pollution that can be from sources like solid waste, thermal, sediments, etc.
Biological pollution consists of infections stemming from two sources. The first is a direct source such as from the microbes in the water like typhoid, cholera, etc. that when drunken directly are known to cause symptoms like hepatitis and dysentery. The other is from an indirect source like water breeding carriers, like the infamous mosquito, that spread diseases such as yellow fever, the West Nile virus, malaria, etc.

Water pollution what is water pollution? Water pollution is where things are either purposely or accidentally putt into water it can also happen naturally. Dirty water can give humans ecoli and other bacterial diseases which may cause diarrhoea. Also contaminated water can not be used
Pollution is the presence of dangerous and unwanted substances in the ecosystem that causes imbalance and health hazards to the living. Water pollution is the presence of unwanted substances or particles in water, which causes imbalance in water systems. Lake Huron is among the largest fresh water sources in the States located in North America.
It will not have any affects on the surrounding communities that reside amongst the rivers and lakes and will not be any kind of annoyance or inconvenience to their neighbors. It will only be there to help and nothing but benefits will come from it.
Pollution in the Great Lakes is a big problem and it is very serious. Water pollution affects health of the living organisms in the lake, and soon it can affect the health of us human too. Water Pollution occurs when, people dump their stuff into the water, and factories dump their stuff into the water etc. This is an example of non-point pollutionm. Firstly, it affects the organisms life because all or trash gets into the fish environment and trappes the fish,
There are many different kinds of water pollution, which is why these poor third world countries have a large lack of fresh water. These different water pollutants come from everywhere not just bacteria and microorganisms. Pollution also comes from runoff: a draining away of water from areas where no more water can be absorbed. Another type of pollution is marine: harmful or potentially harmful items affecting marine and human life. These pollutants are contaminating water all across the globe that are killing thousands of people a day.
First a background on the problem with water pollution must be given. Both oceans and freshwater
due to pesticides, fertilizers human waste, mining, and manufacturing, the water is getting polluted. Pesticides cause water pollution by flowing into the runoff water that travels to the lake and gets polluted. Fertilizers cause water pollution because now farmers are using chemcal based fertilizers that cause the ground water to become contaminated or polluted over a long period of time. Human waste causes water pollution because it has many chemical that would be very harmful if it was ingested. Mining causes pollution because the machines that excavate the coal or ore use water to cool down. This run-off water, if released to a body of water, will cause algea growth and kill fish. Manufacturing Causes pollution as well because the machinary used to manufacture goods uses water cool down and when released to water, it increases bacteia to grow and kill fish.
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.
Water covers 70% of our planet, and it is easy to think that it will always be plentiful. However, freshwater, what we drink, bathe in, irrigate our farm fields with makes up only 3% of the world’s water, and two-thirds of that is stored in frozen glaciers or unavailable for our use. Many of the water systems that keep ecosystems thriving and feed a growing human population have become stressed. Rivers, lakes and aquifers are drying up or becoming too polluted to use. Already, 80 countries suffer from water shortages that threaten health and economies while 40 percent of the world—more than 2 billion people—does not have access to clean water or sanitation
Today pollution is very high in both inland and marine waters. All different types of water pollution are contributing factors in this problem. Here are some things that are associated with pollution: Pathogens: Pathogens are disease causing bacteria, viruses, and protozoa. They usually come
All around the world, countries are fighting to keep their drinking water clean. Whether it’s streams, rivers, or lakes, countries have taken great measures to maintain high quality drinking water for both human consumption and animal consumption. Countries must first understand the sources of the polltion, then determine the best methods to eliminate the pollution. Clean drinking water is a valuable resource and a the key to human survival. Plants and animals also depend on water for their growth, so all water must be kept clean. The major contributors to water pollution can be classified in three categories, industrial, agricultural and municipal.
Human has always been in great need of fresh water for many purposes, and there are three main categories of extractive uses of water from its natural system: agricultural irrigation, industrial and commercial activities, and residential activities. In addition to extractive uses, in-stream uses of water are also essential for human in pollution dilution, maintenance of navigation paths, and protection of biodiversity. These water usages can have adverse effects on the quality and quantity of freshwater, and furthermore these impacts may not only threaten ecosystem, but also make transitions in economic and social aspects. From this, it can be seen that society and ecosystems are interdependent. However, traditional environmental scientists tended not to give great weight to the human factor in their studies. However, the growth in global population leads to a rise in demand of freshwater, and now it is unreasonable to deny the truth that humans make huge impacts on water resources. Human-induced environmental contamination creates severe
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.
Szewzyk et al (2000) reported that the available fresh water for human utilization is hardly 0.3 to 0.5 % of the total water (2.4%) available on earth and thus it is important to use it wisely. The most important and potable source of water is river water. Rivers are important fresh water resources and most developmental activities are dependent upon them. The environment and economic stability, are highly impacted by quality of surface waters. According to Halder and Islam (2015), unfortunately the water quality of rivers all around the world is deteriorating due to increase in population, urbanization, Industrialization, evolving consumption patterns, global climate change and various other factors. The continued anthropogenic activities have stressed the ecological functioning of the rivers to an
