Water, Its Amazing Facts

Water ' its amazing facts!

Abstract“We never know the worth of water until the well is dry.” Thomas Full affirmed. Have you ever think of the importance that water has in our lives? Water makes up more than two thirds of human body weight, and without water, we would die in a few days. The human brain is made up of 95% water, blood is 82% and lungs 90%. Therefore, we need to drink daily more than 2 liters of water approximately, but you need to be sure is completely ready for drinking. Water most be cleaned by different methods. If not, many people could get sick. Therefore, we can conclude that water is really important in our life. Besides the human body, there are many ways that we use water and that is partly why it is so important to conserve it. We extract a lot of water from rivers and lakes around the world for our own needs. For example, we use water for washing and drinking, to grow food, to generate energy , and for many other useful purposes. The content of this poster is really interesting. It contains information of the domestic uses of water, its disposal to drainage, actions that increment water pollution and how it affect use, rainwater in the storm drainage systems, major pollutants, the water in dams, pollutants in rivers and streams, water treatments for domestic use, sources that supplies drinkable water in the metropolitan area of Monterrey, among others. It is important to understand the function of water. If we polluted it, later we will suffer the consequences. Water is our most precious resource! We need to take care of it!

IntroductionThis substance known as water, is one of the most essential elements to health and is so important that your body actually has a specific drought management system in place to prevent dehydration and ensure your survival. Water might be everywhere, but one must never take it for granted.Water makes up more than two thirds of human body weight, and without water, we would die in a few days. Water is important to the mechanics of the human body. The body cannot work without it, just as a car cannot run without gas and oil. In fact, all the cell and organ functions that make up our entire anatomy and physiology depend on water for their functioning.Water serves as a lubricant in digestion and almost all other body processes. The water in our saliva helps facilitate chewing and swallowing, ensuring that food will slide easily down the esophagus. Water also regulates body temperature, our bodies can control over-heating through perspiration from sweat glands in the skin and from evaporation which produces a cooling effect. Blood is also routed into areas close to the surface of the skin where it can be cooled and then carried back to the interior of the body. Drinking eight glasses of water daily can decrease the risk of colon cancer by 45%, bladder cancer by 50% and it can potentially even reduce the risk of breast cancer.Since water is such an important component to our physiology, it would make sense that the quality of the water should be just as important as the quantity. Therefore, your drinking water should always be clean and free of contaminants to ensure proper health and wellness.

''Domestic uses of water ' its disposal to drainage''Domestic water use is water used for indoor and outdoor household purposes— all the things you do at home: drinking, preparing food, bathing, washing clothes and dishes, brushing your teeth, watering the yard and garden, and even washing the dog.Everyday household activities contribute to water pollution. When it rains, fertilizer from lawns, oil from driveways, paint and solvent residues from walls and decks and even pet waste are all washed into storm sewers or nearby lakes, rivers and streams -- the same lakes, rivers and streams we rely on for drinking water supply, boating, swimming and fishing. Also, improper handling of materials around the house can lead to pollution. Here are some ways you can help reduce your impact on waterways.

''Rainwater in the storm drainage systems ' Major pollutants.''Most of our rainwater travels through gutters, storm drains, channels, washes and eventually into the major source of our drinking water. The largest source of stormwater pollution in the world results from everyday activities. The most common pollutants are:•Trash (fast-food wrappers, cigarette butts, styrofoam cups, etc.)•Toxins (used motor oil, antifreeze, fertilizer, pesticides, sewage overflow, pet droppings, etc.)These pollutants are picked up as water (from rain, hoses, sprinklers, etc.) drains from streets, parking lots, and lawns and enters. From there the polluted urban runoff and rainwater flows through a massive system of pipes and open channels.Basically, anything dumped or dropped on the ground or in the gutter contributes to rainwater pollution.

Atmospheric PollutantsRain water is naturally acidic as a result of carbon dioxide dissolved in water and from volcanic emissions of sulphur. However, it is the chemical conversion of sulphur and nitrogen emissions from power stations, factories, vehicles and homes, where fossil fuels are burnt, that we call acid rain. These waste gases are carried by the wind and can in time be converted into sulphuric and nitric acids, having travelled many hundreds of miles. These produces acid rain contaminating the clea water of lakes and rivers.Urban PollutantsWater running through land surfaces tends to pick up gasoline, motor oil, heavy metals, trash and other pollutants from roadways and parking lots, as well as fertilizers and pesticides from lawns. Sedimentation often settles to the bottom of water bodies and can directly affect water quality. Excessive levels of sediment in water bodies can increase the risk of infection and disease through high levels of nutrients present in the soil.

''Water in dams''What would you do without water? Why are dams necessary and important in life? People build dams to control water. So, they make sure that the right amount of water is at the right place and at the right time. We know that without water we are vulnerable. A clean, sustainable water supply is vital for our health. Also, they are important because provide water for industry, water for irrigation, water for fishing and recreation, water for hydroelectric power production, water for navigation in rivers, reducing or preventing floods.

Pollutants in rivers ' streamsWater is essential to life. We cannot live without it. Nowadays, the world is suffering different types of pollution. Yet water pollution is one of the most serious ecological threats we are facing today. In this section we will talk about the situation that rivers and streams deal daily according to the pollution situation. First of all, what is a stream? A stream is a body of water flowing in a channel or watercourse, as a river, rivulet, or brook. Streams have an important job. They drain the landscape, and move water and minerals towards the Earth’s oceans. But, what is a river? A river is defined as a large natural stream of water emptying into an ocean, lake, or other body of water and usually fed along its course by converging tributaries. In these days the problem of the pollution is completely affecting the rivers, the streams and the organisms that live from them.•Many streams and rivers are polluted all around the world. The causes of pollution depend on many different factors. These factors vary depending on the place they are located. Rivers and streams drain water that falls in upland areas. Moving water dilutes and decomposes pollutants more rapidly than standing water, but many rivers and streams are significantly polluted. There are three major sources of pollution (industry, agriculture and domestic) that are concentrated along the rivers. Industries and cities discharge its wastes by throwing them to the rivers or streams. Examples of pollutants that the industries emit include cyanide, zinc, lead, copper, cadmium and mercury. These substances may enter the water in such high concentrations that fish and other animals are killed immediately. Also, agricultural activities have tended to be near the rivers, because river floodplains are exceptionally fertile because of the nutrients that are deposited in the soil when the river overflows. Therefore, pesticides are used in agricultural activities to control weeds, insects and fungi. Run-offs of these pesticides can cause water pollution and poison aquatic life. Subsequently, birds, humans and other animals may be poisoned if they eat infected fish. Under those circumstances, we need to be conscious with the activities we are performing. People around the world are polluting without thinking the consequences. That being the case, the life of many aquatic living things and our life will be on risk.Water Treatments for domestic useIn an emergency, boiling is the best way to disinfect water that is unsafe because of the presence of protozoan parasites, bacteria or viruses.If the water is cloudy, it should be filtered before boiling. Filters designed for use when camping, coffee filters, towels (paper or cotton), cheesecloth, or a cotton plug in a funnel are effective ways to filter cloudy water.To remove impurities from water by distillation, the water is usually boiled in a chamber causing water to vaporize, and the pure (or mostly pure) steam leaves the nonvolatile contaminants behind. The steam moves to a different part of the unit and is cooled until it condenses back into liquid water. The resulting distillate drips into a storage container. Anything that won't boil or evaporate (salts, sediments, metals, among others) will remain in the distiller and must be removed.

REFLECTIONSBrenda: The water is an indispensable thing in the world and in our organism. If we don’t take care of the pollutants we throw to the rivers, lakes or streets the process of cleaning the water will be more difficult and we won’t be able to drink water for longer time. If there is no water, we won’t be able to do a lot of things such as shower, eat clean food, wash our clothes, we won’t be hydrated and our world will have an end soon. To avoid this in the future, we can take responsibility by now and take care of what we have today. Spending less time showering, or cleaning the cars with a tray instead of a hose, will completely reduce our threat of finishing the clean water of the world. Valery: Water is the most important nutrient in our body, we should be more responsible about it, research and learn more about what really happens when we dispose the water we use in our house, because the products we use may damage rivers, lakes, and more. So we should use devices and special “green” products to save the water from being contaminated.Mariely: This activity makes me think of the essential role the water has in my life. I conclude many things from this activity, but I will mention the most relevant. “No water, no life. No blue, no green.” This is a quote of Sylvia Earle that defined in few words what I think of the importance of water. First of all, water is really important in our body because makes up more than two thirds of human body weight. We completely depend of water. We need to drink the sufficient water (2 liters per day approximately), so our organism can continue working properly. Also, water is necessary to do the dishes, to take a shower, to flush the toilet, to cook diner and for many other purposes. Also, it is used by industries and in agriculture. Some people think that the environment it is not important. Others only look for the best in their business. Consequently, home wastes, chemicals of the industries, pesticides, and other pollutants are damaging our world. The worst of all is that we are killing ourselves in an indirect way. Rivers and streams are getting polluted each time more. Therefore, the process of cleaning the water would be more difficult. Consequently, we can get sick. By the other hand, we need to care our health. By different domestic methods we can get completely sure that the water we are drinking is purified. We can make a change! Take care of the water and stop polluting. Mariana: Mankind is destroying water resources because we are contaminantion the last resources we've got. Every action we do in terms of wasting or not taking care of water are a big deal because in a long term we'll not have enough water for our population and worst! for the world. We need to take care of our vital element that is our precious water.Team Reflection: Water is indispensable for life; water makes up most of the organisms. If we don’t take care of it, in a few years we won’t be able to do the activities we make today, such as drinking, showering, or washing or clothes. Imagine life without being able of washing our teeth. The human activities are damaging the process of cleaning water, thanks to all the trash we are throwing to the streets that go directly to the rivers and lakes, making more difficult this process. In this project, we realize that the process of cleaning water is because the actual human activities are contaminating the world, and while the years pass, is more difficult to take out the toxics that industries produce and throw to the atmosphere. We could avoid these problems if we stop throwing trash to the streets, or spending less time taking a shower or if we close the faucet while we are washing our teeth. We should make conscience in the people, that we need to act now before it is too late and life can’t continue in the way that it is today.

5 tips for the care of water1.Use nontoxic household products whenever possible. Discarding harmful products correctly is important, but not buying them in the first place is even better2.Recycle and dispose of all trash properly. Never flush non-degradable products -- such as disposable diapers or plastic tampon applicators -- down the toilet.3.Correctly dispose of hazardous household products. Keep paints, used oil, cleaning solvents, polishes, pool chemicals, insecticides, and other hazardous household chemicals out of drains, sinks, and toilets. Many of these products contain harmful substances4.Use native plants and natural fertilizers. Native plants need less water, are more tolerant of drought conditions, cost less to maintain and provide habitat for birds and butterflies. Apply natural fertilizers and soil conditioners, such as compost, peat, rotted manure, and bone meal to stimulate plant growth and retain soil moisture.5.Decrease impervious surfaces around your home. Having fewer hard surfaces of concrete and asphalt will reduce runoff from your property.

Sources that supply drinking water in Monterrey.There is always a company that is the responsible to provide biologically and chemically safe water. Unfortunately, it is not always the case. It is important, though, to obtain and read the annual Water Quality Report that the water company is required to make available to you. The contaminants most people using public water would be liable to experience at harmful or unacceptable levels are:•Residual disinfectants (chlorine and/or chloramine, for example) added to keep water safe during distribution.•Disinfection by products, like the trihalomethanes.•Lead (many homes leach lead into the water from pipes and/or fixtures).•Brief, accidental contamination by microbes (coli, giardia, cryptosporidia, etc.) or other contaminants.The main source that supplies drinking water in the metropolitan area of Monterrey is the “Cuchillo reservoir”. Servicios de Agua y Drenaje de Monterrey (SADM) is the responsible of the water that goes to our homes. This company has its short and long term strategies for giving service to all the people of the metropolitan area of Monterrey. Also, this area has a “well-fields” that supply less than the half percent of the water the city and its metropolitan area need. The purpose of these walls is to use them as “storage reserves” in case of an emergency, like a drought.
