The increasing demands of clean water in the developing countries, threaten the biodiversity and human needs to survive, towns and cities in such countries are under a severe environmental stress. Cities have grown over past decades due to migration, increase in trade, tourism, and other activities. This created over population in urban areas more than they could handle. Drinking water and sanitation facilities are being hard to provide for the high number of citizens. The water supply and sanitation systems in these urban areas are usually have the following issues:
• Existing sources are exhausted or polluted, so Raw water is transported from distant source, this consumes energy due to transportation. • More treatment steps which include

In near future, the climate change and the rise of the sea level will make more complications for this problem. In other words, coastal cities are faced with resource depletion, increased energy consumption, water pollution, eutrophication and waste generation. The intention of this paper is to explore the interaction of environmental issues relating to drinking water supply in developing countries. The use of Vechtplassen or Vecht Lakes of North Holland region in the Netherlands as a case study will be made to show a successful attempt to preserve fresh water and it’s the most famous man made water bodies that supply fresh water. The paper evaluate existing systems, presents their environmental indicators and brings out the environmental impact, with new scientific and technical methods that can be used to solve these issues, for example by decreasing soil erosion, introducing caltrope technique, and applying …show more content…
Secondly, an analysis of current situation and issues of water supply. Thirdly, environmental effects of these issues are discussed followed by an assessment of fresh water quality and availability. Finally, analyzing several case studies and comparing them to come up with the most efficient methods and strategies, to sustain fresh water and the
Bringing clean water to a different location in developing countries has many challenges; this is why the organization has to build a good relationship with the local community. In this case, with bringing new technology to the community, it will bring positive and negative impact. It is important to the organization to know how the community and their culture adapt to this new technology. In their website, they proclaim that they work with the community to find the best solution for everyone. These types of solutions will be different in every
Mexico is high-urbanized country. Almost 78% of its citizens live in cities (Castro and Heller 2009). That is why citizens of urban areas suffer the most from the appreciable water shortage. The situation with water supply in urban areas is critical. As an example, Mexico City, with population about 20 million people, faces quite serious scarcity of water. It obtains water from 3 main basins, all of them are overexploited (UNESCO 2006). The solution of the government to this problem was to pump water from the aquifers. However, these palliative actions of the government have not solved the problem, three aquifers from which city gets water are overused (UNESCO 2006).
This is because only a small part of the population, particularly in developing countries, have access to water of acceptable quality. It is estimated that in some countries only 20% of the rural population has water of satisfactory quality. Based on these statistics, it is clear the urgent need for awareness about caring for water use. Almost without realizing it, we are seriously jeopardizing this essential resource, not for us but for our children's children and their generations, aware that in other parts o...
This experiment was used to see the effect of salt water on the algae in the freshwater tables. The effect of salt water on algae will make the algae decrease in number. The algae were used as an indicator organism to give an idea of pollution concentrations. (Colgan, 33) Salt water can cause many problems if the salt water should enter the freshwater ways. This salt water can contaminate the aquifers and drinking waters of the world. This idea is backed up in Spatafora’s saltwater intrusion paper “When this occurs, it will move the saltwater freshwater interface inland, resulting in a higher saline concentration in the aquifers' water, rendering it useless for human consumption, unless it is treated.”(Spatafora, 2008) Not only can the saltwater effect the drinking water this water can also not be used for irrigation as seen in F. Lugoli’s article about the contamination of southeastern Salento’s groundwater “The results indicated widespread pollution from salt and microbial contamination. Contamination from faecal microorganisms posed a significant risk of human infection in 100% of samples. Furthermore, the water was unsuitable even for irrigation in a high percentage of cases (31.8%), which is of considerable significance given that agriculture is one of the most important economic activities in the area under study.”(Lugoli, 2010) The salt water can also kill the plants, algae, and ultimately the animals that use that water for water and food. The rising amounts of saltwater can cause plants to die as seen in Winn’s Saltwater Intrusion and Morphological Change at the Mouth of the East Alligator River, Northern Territory article “Significant morphological change has occurred since 1950, with the tidal creek extending 4 km inlan...
Clean and safe drinking water resources are becoming scarce as the population grows. The world is facing many problems, but the most important thing needed to survive, is water. Water is getting low in many countries, therefore residents are suffering the misfortune of not having the reliable source of clean water. Today many countries are having water shortages meaning rivers, lakes, streams and groundwater are not enough to rely on for supplying water demands. For example, California is facing a drastic water shortage, the natural water resources are not enough to fulfill their water demands.
There will growth of water born diseases increasing health hazards and degradation of environment and ecosystems. This affects the natural environment system leading to exaction of some species. And the due contamination of water can also lower the production of agriculture products and other economy activities will decrease. If there will more water bodies pollution it also has negative effects on its environment there decline of economy of the country. Since more of the country budget have invest on the health sectors. The country major users of water are agriculture, intensification hydropower and industrialization. Urbanization is another significant challenge. Rural-urban migration increases pressure on urban infrastructure and services and cause environmental problems which will lead to water pollution.
Water is one of the most essential non-renewable natural resources on the Earth. Technically, an un-hydrated human being can live no more than three days. In the United States, people consume water mainly from tap water and bottle water. However, the consumption between these two sources is not even but lean to one side heavily. According to the Natural Resources Defense Council, people consume from 240 to over 10000 times more per gallon for bottled water than they usually do for tap water. (NRDC) In addition, according to a survey from US National Library of Medicines, only 17% of the participants prefer to drink tap water exclusively.(US National Library) Compared to the bottled water which is shining like a superstar, tap water is like a diligent worker in the shade, unpopular but useful. The extremely unbalance of bottled water consumption implies that a commonly hold conception exists: bottle water is superior to tap water. In fact, scientific evidence proves that tap water is nothing different than bottle water. More importantly, the excessive consumption of bottled water is an irrational use of resources and creates severe environmental issues.
It might be easier to live a healthy life for many people, but for others it can be very challenging. I have tried to be healthy so many times, but I always fell off the wagon. For many days I would “feel” healthy, but in reality I was not the healthiest person mentally or physically. I knew that I had to change my behavior, and become healthier (or at least almost healthy) if I wanted to live a longer life. I began my journey by drinking more water, balancing my eating with exerting, all while trying to stay mentally well.
There are many types of pollution. The main types of pollution are water, air, soil, thermal, radioactive, noise, and light. The topic for this experiment is Water Pollution. Water Pollution became a problem in the 1900’s when water started being treated like sewage. Earth Day was founded by United States Senator Gaylord Nelson on April 22, 1970 because of 1900’s pollution. Water Pollution also affects humans and animals. There was a Cholera outbreak in 1854, before water pollution became a problem, and a Typhoid outbreak in New York from 1900 to 1915. There are multiple possible causes to Water Pollution. Humans let out chemicals into the environment, and when some of those chemicals
Freshwater is quite scarce, but it is even scarcer than one might think: about seventy percent of all freshwater is frozen in the icecaps of Antarctica and Greenland and is unavailable to humans. Most of the remainder is present as soil moisture or lies in deep underground aquifers as groundwater. It is not economically feasible to extract this waster for use as drinking water. This leaves less than one percent of the world’s fresh water that is available to humans. It includes the water found in lakes, reservoirs, groundwater that is shallow enough to be tapped at an affordable cost. These freshwater sources are the only sources that are frequently replenished by rain and snowfall, and therefore are renewable. At the current rates of consumption, however, this supply of fresh water will not last. Pollution and contamination of freshwater sources exacerbate the problem, further reducing the amount of freshwater available for human consumption. Something must be done if humans want to even survive in the near future: the lack of clean drinking water is already the number one cause of disease in the world today. The first step is worldwide awareness of the water crisis: governments and the citizens they govern worldwide need to know about this problem and be actively involved in solving this problem.
Wastewater is the combination of water-carried or liquid wastes starting in the sanitary conveniences of dwellings, industrial or commercial facilities. In addition to this, surface water, groundwater and storm water may also be present. It is any water that has been badly affected in quality by anthropogenic influence. It contains waste from residential, industrial and commercial processes. Municipal water contains industrial wastewater, sewage and gray water. Gray water is the water from sinks and showers. Large industries also produce wastewater.
Being able to provide clean water will have the greatest potential impact on our society in the next 30 years and onward. Although Earth’s surface is 71% water, many third world countries still lack access to clean water. It may seem that our main use of water is for drinking and sanitary use, but 69% of the world's fresh water is used for agriculture. Only 12% of water withdrawals are for households and municipal use. This grand challenge will have the greatest potential on our society on decreasing death rates due to unsanitary water and sanitation facilities.
The problem of water scarcity has increasingly spread throughout the world as of yet, The UN reports that within the next half- century up to 7 billion people in 60 countries which is more than the whole present population will face water scarcity (Sawin “Water Scarcity could Overwhelm the Next Generation”). As well the demand for freshwater has tripled over the past 50 years, and is continuing to rise as a result of population growth and economic development. 70% of this demand derives from agriculture which shows the influence of water on food supply globally as well not just drinking water (Sawin “Water Scarcity could overwhelm the Next Generation”). But increasing water use is not just a matter of the greater number of people needing it to drink and eat; it also comes from pollution and misuse of water supplies, by either dumping or runoff of bacteria or chemicals into water. This also “causes other pollutions as well such as soil and air pollution, accelerating wetland damage and human caused global warming” (Smith and Thomassey 25). According to UN report, recent estimates suggest that climate change will account for about 20 percent of the increase in global water scarcity in coming decades.
Fresh water is a limited resource in many parts of the world. And this will become more dearth due to increasing in population, urbanization and climate change. The major fact for this paucity of fresh water is not only due to demand for water but also due to pollution in freshwater ecosystem. Due to the pollution created by human beings in this ecosystem, the usable water has decreased drastically and the cost of purifying the water has increased dramatically. The main sources of water pollution are point source and non point source. Point sources include pipeline discharge of pollutants such as domestic sewage discharge industrial waste effluents from factories or plants, to receiving waters. In contrast, non-point pollution results from storm runoff, which transports polluting materials diffusely over land.
Less than 1% of the water supply on earth can be used as drinking water.
