Living in a world that is roughly 70% water, and all living creatures found on this planet depend on this resource whether directly or indirectly, making water quality an important topic and vital to sustain our world of cycles. “Determination of status of water quality of a river or any other water sources is highly indeterminate. It is necessary to have a competent model to predict the status of water quality and to advice for type of water treatment for meeting different demands.” (Bai V, 2009) With most of our water on this planet made of salt water and our constant damage towards the remaining water that can be consumed by humans is diminishing with improper distribution on a global scale. If our greed comes before companionship, and our quality of life is more important than pollution, then our future generations to come will be born into a world of chaos, and a scarce of a basic human necessity.

For my first experiment, my hypothesis was “If oil is applied to ground water, then the groundwater will become contaminated and oil will be present. If vinegar is applied to groundwater it would have the least effect on the water, showing clear visibility. If laundry detergent is applied to groundwater, the groundwater would be more clouded then oil and vinegar especially if stirred.” For my second experiment my hypothesis was “If my filtration technique to remove contaminants is to separate the contaminated water and over time after treatment the water would become clean. For my third and final experiment my hypothesis was “As a consumer, who drinks mainly Dasani bottled water, I believe this would be the least contaminated water. Seeing as tap water is coming from a city water supply and has not been thoroughly filtered unlike bottled water it would be the most
Water is the dominating force of life; it has etched, carved and determined the fate of humanity itself since the beginning of time. All living organisms are reliant on water; forced to migrate or adapt at a turn of events as simple as a drought. Despite pipes, wells and most other man made engineering, even humans still spend their days chasing clouds. So for once on this planet there are no arguments, no debates, as to the fact that we need water to survive. We even depend on the undrinkable oceans coating the earth; that act as a shelter for tens of thousands of ecosystems, food chains, and organisms. Some of which have achieved such a precarious balance, that the loss of any creature in a food web may lead to the downfall of the planet itself. “We are already well into a new geological era… where human interference is the dominant factor in nearly every planetary ecosystem, to the detriment of perhaps all of them” (Lynas, 49). So why exactly are humans shifting such an important balance for the sake of excess? We’re tipping the scale; and might not be able to tell when the water starts to burn. Ocean acidification is a process that disrupts some of the most important biological functions and processes that all living organisms are dependent on.
Our planet, Earth , the surface is covered by 70% of water, so, water is one of the crucial natural resources to living thing, not only human beings, but also animals and plants. Water is used in almost every crucial human daily activities and processes. Hence, water plays an important role in either domestic work or industrial activities. However, the world today is, the pollution of this important resource is happening, and become worse and more serious, day by day, year by year. This problem really gives us a rude shock.
The experiment started by labeling a piece of filter paper with my initials with the following A, B, C, oil, and H2O. I placed two drops of each unknown milk sample, vegetable oil, and H2O next to the labels on my filter paper and allow to air-dry. After these samples were dried, I placed the filter paper in a petri dish containing Sudan IV solution and stained the filter paper for one minute. I then used the forceps to remove the filter paper to the rinsing dish. Then, I rinsed the filter paper with water and collect the runoff in the dish. The last step, I placed the filter paper on the table and allowed it to
Pollution comes in many forms. In the ocean we dump a variety of substances, including human wastes, chemicals from fertilizers, oil, and trash such as plastic which all contribute to the growing issue of our ocean pollution. In addition to, our usable waters are finite. More than 97.5 percent of the water on this planet is undrinkable salt water; the remaining 2.5 percent has two-thirds of the usable fresh water locked up in glaciers, snow, and permafrost. Of the one-third of freshwater that is available for human use, 20 percent is used for industrial use. (“Water Pollution”) “In effect, water pollution reduces the volume of water available for use by human and other populations.” (Robin Clarke, Jannet King) Knowing that there are approximately 7.2 billion people and growing on this planet with only 0.83 percent of available for our use wouldn’t you want to do everything possible to help put an end to water pollution? (worldometers)
Introduction on Water It covers 70% of our planet, makes up 75% of our body, it is necessary for survival and it is declining at a rapid rate (http://www.sscwd.org). It is water. Unfortunately, clean water is rare, almost 1 billion people in developing countries do not have access to water everyday. “Yet, we take it for granted, we waste it, and we even pay too much to drink it from little plastic bottles” (The Water Project). Use of earth’s natural resources should be seen as prosperity, although it is taken for granted, every aspect of daily life revolves around the environment, forcing water conservation to be necessary for future on this planet.
Water is considered the most abundant compound material on the planet, and is also essential for all living habitants. Two thirds of our world’s surface is made up of water and close to 70 percent of the earth is made up of human beings, thus there is a clear sight that water is the prime element which is responsible for life on earth. No matter the essence, water is a resource we cannot do without especially to maintain a certain quality of life. As a society we need to do everything that we can to sustain its quality and quantity in order to also sustain the life on earth for not only today, but tomorrow as well. Human beings have lost respect for water, which is evident in how we dump sewage, garbage and chemicals in our rivers and other water bodies, exploit the living bodies in the water even to the point of extinction.
Today's waters are constantly being treated like sewage dumps or trash cans. We use them as garbage cans every day polluting the water more and more. "Pollution is often by way of rivers, drains and outflow pipes." Causing an outflow of sewage into our ocean waters. This is not only affecting the community but also the marine life and other sea creatures living in the ocean." This pollution includes human sewage and domestic waste water, factory outflows of acids and poisonous metals, engine oil from roadside drains and garages, farm chemicals washed off the land by rain, building-site rubble, nuclear waste from power plants, and oil from wells, refineries, and tankers." Stating that most of today's waste is from factory or factory ran products that shouldn't be polluting the water
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.
The government must do something to improve the situation, and in the past decade, it did make an effort. There were rules and policies dealing with the environmental problems. For example, in 1984 and 1985, two policies “Provisions on Effluent Charges and Fines of Shanghai” and “Rule of Shanghai Huangpu River on Protection of Upriver Water Resources” were issued (Wang, Da, Song and Li). But producing general regulations is merely the very first step, and there are a lot more to consider. On a spanned period, the authority in New York City implemented different programs to protect the watershed in order to improve drinking water. In this case, Shanghai government and environmental organizations can definitely learn from them.
Of this water approximately 97% is salt water, 2% frozen in glaciers, and only 1% is available for drinking water supply using traditional treatment methods” (Thornton). Therefore, properly treated or disinfected water can help to reduce the spread of water-borne diseases. Everybody around the world depends on water, so people need to be perceptive of the water challenges. A lot of clean, useful water is wasted by humans all the time, so people don’t care about saving water because they have easy access to it.
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.
Freshwater in the world makes up only a small portion of water on the planet. While the percentage of water in the world is nearly 70%, only 2.5% is consumable. Even further, only <1% is easily accessible to basic human needs. According to National Geographic, “by 2025, an estimated 1.8 billion people will live in areas plagued by water scarcity, with two-thirds of the world's population living in water-stressed regions as a result of use, growth, and climate change.” With this current trend, water will become more immersed in environmental, economic, political, and social changes. Many of these in later years shall need to be addressed as tension rises:
The world has more than doubled its human population since 1950. In general, people are wealthier, consume more calories, and eat more meat and thus require more water to produce food. More pressure is placed on the environment and as a result, the quality of the water that is available for drinking, food production, and marine life is depleting.(839).
An interesting test was given out in December 2013 by Dr. Richard Besser from ABC News at Centre Park in New York to see if people can distinguish tap water from bottled water. Two big jars are filled up with bottled water in jar A and tap water in jar B. People walked by were invited to taste water in different jars and vote for the one they thought was bottled water.(ABC News) The result reveals that the difference in taste between tap water and bottled water is negligible: eleven people choose jar A while nine people choose jar B. However, this result should not be astonishin...
Water quality can be described as the measurement of the condition of water relative to the requirements of humans, animals and plant’s need. When we talk about water quality testing, we are highlighting a critical piece of natural observing for civil engineers in order to create a specific structure or decision. At the point when water quality is poor, it influences almost every single form of life in our planet; going from plants to animals and thereon. Hydrology, in the other hand, is the study of water. It is important to state that hydrology is a critical part for civil engineers to determine and predicting decisions that will affect our biological environment.
