Introduction: It is expected that as populations and economies of coastal regions grow and as the climate changes, there will be a greater demand for public supply of water. Exploitation of available water sources will therefore increase in order to meet these increasing demands, thus all responsible people to supply, oversee, and regulate public utilities must ensure the correct use and exploitation of hydraulic resources. Since surface water has been severely contaminated and diminished in certain regions, and treatment of these waters is costly, some utility providers find exploitation of groundwater to be an efficient source. Aquifers are the primary structures for storage and transportation of groundwater in all regions, including inland and coastal. What differentiates an inland aquifer from a coastal aquifer is that the later interacts with the ocean on the surface as well as underground. Freshwater coastal aquifers ultimately recharge at the ocean and therefore the interactions can cause the freshwater aquifer to be affected by the ocean as well as its saltwater aquifer. Given that inappropriate uses of the coastal aquifers could result in irreversible damage to a point of complete deterioration and inability to use an aquifer due to public safety concerns, there is a necessity for methodologies and strategies for more appropriate uses of water resources in a way that is in harmony with the physical and the socioeconomic environment. The tools for modeling to quantitatively measure the supply of available groundwater will facilitate the creation of management plans that will permit a more correct management in order to stabilize economic growth, population growth and make sure it will be in par with sustainability and avai...

5. Dissolution of groundwater from evaporate materials incorporated in the stratigraphic column. Intense pumping may induce leachate of salts contained in zones of low permeability.
6. Displacement of groundwater contained in deeper aquifers. The upward movement of groundwater containing a high salt content from deep confined aquifers to more shallow aquifers can cause the increase in salinity.
7. Infiltration of sewage water or irrigation water for domestic or industrial use infused with dissolved salts.
8. Infiltration of brackish water from estuaries or artificial canals may be a source of salinity. In this case, there may be 3 types of water interacting in the same aquifer.
9. Brackish water, brine, or chlorinated water may be trapped in a geological medium may be mixed with water closer to the surface, given the right conditions.
In the state of Florida majority of its drinking waters comes from these deep layers of limestone that actually stores water. Florida has the most springs and are quite unique to the earth’s ecosystem and is the greatest groundwater system on earth. Furthermore, the water from the Florida aquifer
Climate Change and Global Warming cause sea levels to rise. This increase in sea levels not only causes inundation of low lying and coastal areas but also irrevocable damage to coastal environments. Globally the ocean is predicted to rise nearly 140 cm on a global scale by the year 2100 (Cooper et al. 2013); therefore this has massive implications for countries all around the world with cities (settlements etc.) based near bodies of water. When compared to the last 80 years this is an acceleration of nearly twice the rate that ...
Water is the most relied upon resource on earth and if it disappeared life could not and would not exist on this planet. So if one of our main sources of water in South Australia, The Murray Darling-Basin, becomes unusable then we would need to find the problem and do everything possible to stop it or counteract it. This report investigates on salinity in the Murray Darling-Basin, using the issue question “Is there enough being done to counteract the effects of salinity in the Murray?” as the focus. Salinity is a key significant environmental challenge which the Murray faces and if left unmanaged it could cause serious implications for water quality, plant growth, biodiversity, land productivity, infrastructure and could lead to a loss of a water source that’s critical to human needs. In this investigation five different aspects of this salinity issue are presented and these aspects include what Salinity is and how it has become an issue, what the effects are, how salinity affects the rest of Australia, what can be done and is anyone doing anything and finally what the visions are for the future of the Murray and its salinity levels.

One of the largest geographic physical structures in the United States is the Colorado River. Human activity and its interaction with this great river have an interesting history. The resources provided by the river have been used by humans, and caused conflict for human populations as well. One of these conflicts is water distribution, and the effects drought conditions have played in this distribution throughout the southwestern region. Major cities such as Las Vegas, Los Angeles, San Diego, and other communities in the southwest depend on the river. It provides water for over 20 million people, irrigation for 2 million acres of land, four thousand megawatts of hydroelectric energy, and over twenty million annual visitors for recreation purposes. Also, once in Mexico, the river provides water to irrigate half a million acres of farmland, and municipal and industrial water for 2 million people living in this delta region. The river distributes its flow from lakes and canals along its journey as well. Due to climate change, human demand, natural forces like evaporation and human-induced climate change this water supply is in conflict. Also, a recent change that began in March of 2014 will bring a temporary water surge to the delta of the Colorado River for the first time in many years to help restore this region, and it’s possible it could reach the Sea of Cortez once again.
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).
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.
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.
People from many developing countries are suffering from the scarcity of clean water, while the rest of the country simply take for granted. Habitants of rural poor communities such as Sub-Saharan Africa, are living in a water stressed environment. Residents of these communities have to walk miles at time just to gather water from streams and ponds, even though the water source may contain water-borne disease that can make them very sick. In the rural places that don’t have access to safe clean water, it is very difficult to prevent the spread of viruses. The consumption of contaminated water can be dangerous for health reasons and several people have passed away from these water-borne diseases. Some of these diseases include Cholera, Typhoid, Dysentery, Giardiasis, and Malaria. These unfortunate diseases are currently the cause of numerous deaths, especially in small children. The availability of clean water can prevent many problems in low income communities. The available resources for clean water are very rare, so these water sources need to pass through a process of water sanitation in order to just be sustainable to drink, “The world’s surface is made up of approximately 80% water, which is an indestructible substance. 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

Aquifers feed our rivers and supply much of our drinking water. Groundwater pollution is much less obvious than surface-water pollution, but is no less of a problem. As the long Mediterranean summer drags on and the promise of rain evaporates as quickly as the few fat drops that have fallen here and there, residents of the capital and its surrounding areas find themselves resorting to ad hoc private water networks as the public pipes run dry. "We had originally dug at 30 meters, but we are now digging at 70 meters," one private water supplier and well owner told The Daily Star(Unknown, 2013,page
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.
This paper is about water purification. Water that is safe to drink is called potable water. Our freshwater is definitely not evenly put out throughout the world (www.science.howstuffworks.com). More than half of the world’s water supply is contained in just nine different countries: United States, Colombia, Canada, Brazil, the Democratic Republic of Congo, China, India, Russia, and Indonesia (science.howstuffworks.com). The Middle Eastern countries use the least amount of water per person because there are very few natural and reliable sources of fresh and clean water. Right now more than a billion people (about 17% of the world’s population) don’t have access to clean water (www.science.howstuffworks.com).
Urbanization: Soil is considered as water reservoir. Urbanization acts in creating amount of impermeable surface due to construction of buildings, roads, drainage, sewage, flood relief channel etc. It reduces the amount of infiltration and percolation. Water tends to experiment the runoff process rather than infiltration. This contributes to increase in
