Effects of groundwater pollution
Don’t take our word for it - see why 10 million students trust us with their essay needs.
We realize that extracting from groundwater has advantages as well as disadvantage, in order to provide advantages and disadvantages we first need to know what the meaning of groundwater. Groundwater which is known as aquifer is water that satiates the crevices and openings of rocks and residues that is positioned below the surface of the ground. A mask amount of the groundwater is protected because it is underground, therefore leaving it purely clean and exempt from the pollution on the earth. Now that the significance of groundwater has been stated, the advantages and disadvantages of extracting from it can be summarized (Kreifels, 2011).
There are several advantages of extracting groundwater such as it is good drinking water and beneficial for irrigation; it is use all year; it can be found anywhere; it can be renewable as long as it is not contaminated or over used and it is cost effective compared to most surface waters and water is not lost because of evaporation. The disadvantages are the cost is greater and there is impurity from deeper well; water streams are condensed into surface water; the imposition of saltwater mixing into drinking water distributes close to coastal regions; for years aquifers polluted groundwater; land is descending because groundwater is being over pumped and depletion of aquifer because of over withdrawing (Miller & Johnson, 2010).
Groundwater depletion is a problem in the US and the world because water is being extracted from groundwater as fast as they can replenish them. One reason in particular why depletion occur in the US is that the population has increased and is steadily growing, which causes groundwater to be over pumped. Some levels in the groundwat...

...able amount of energy to keep the pump flowing. The third drawback of desalination is that a massive amount of salty wastewater is accumulated and must therefore for a place to reside. If the salty wastewater is dumped into coastal oceans, it could cause harm to the sea life as well as compromise food resources. Disposing it on the land is not an option either because the groundwater and surface water could become polluted (Miller & Johnson, 2010).

How is development creating longer term problems for groundwater storage ? Cities like Phoenix and Las Vegas are built in the desert. This whole process relies on water from two sources: 1. River water pumped from the Colorado system 2. Groundwater held in aquifers below ground.
Groundwater remained the main supply until 1971 which was when Las Vegas became more dependent on Colorado River water due to the “Southern Nevada Water System” (Brown, n.d.; Larsen et al., 2015). Since then up to 90,000 acre-feet of groundwater has been pumped on a yearly basis, this value surpasses the natural groundwater recharge (Laczniak et al., n.d.). Rain as well as snow serves as the primary sources of groundwater recharge for the aquifers while precipitation plays a minor role (Laczniak et al., n.d.). Due to there not being balanced discharge and recharge this has led to subsidence and as a result of this subsidence the storage capacity of aquifers has decreased due to compaction (Laczniak et al., n.d.). It is estimated that 187,000 acre feet of storage capacity in the aquifers has been lost due to compaction (Laczniak et
Many have always questioned if bottled water or tap water is better for themselves and the environment. Bottled water has many conveniences and is needed, or even wanted, by many people in the United States and all over the world. Water bottles is just not a want for some, it is a necessity. This essay will convince you of the reasons why bottled water is superior to tap water. Not only will you find out why it is superior but why it is important to always have bottled water available to everyone.
For Shiva, the roots of her argument come from a conflict over two different ideological beliefs. One sees water as a common resource that should be freely available and conscientiously conserved; the other sees water as a market good to be possessed, bought and sold. The market proponents argue that the water crisis can be alleviated by privatizing water: places with more water can sell to places with less water and the higher prices will lead to conservation even though those who control the water.
Desalination plants overall could be a huge benefit to society for its high quality of water and intuitive water treatment techniques, however the big environmental impacts and high costs to produce water at a desalination plant makes it unfavorable to most communities especially the poorer communities. Although costs for the production and upkeep for a desalination plant has been going down while the technology of it rises, the only true benefit for having a desalination plant would only come into affect when it is near a body of ocean, such as Tampa Bay Water. All in all desalination plants could soon be the face of future water treatment plants and water sources, but for the present time it is still only a niche water source.
Presently, in the USA the California state is starting suffer with water crises. Therefore, the state started planning many desalination plants. There are three current desalination station, and the government is planning more fifteen. Figure 9 shows the desalinations plants in the California state. There are many critics about the desalinization plants.20 Arguments use against the plants are which use huge amounts of energy, and is very danger for the marine life.20 Desalinated water construction costs approximately $2,000 an acre foot.20 In addition, to produce one gallon of drinking water need two gallons of seawater.20 This process consumes about 38 megawatts to remove 100 million gallons of seawater per day.20

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).
Mexico is the country where water is the serious problem and it is still deteriorating (UNESCO, 2006). In the last two decades, as the population of the country has been growing intensively, the demand for water has also dramatically increased. The number of people who suffer from water shortage is about 11 million; almost 11% of Mexico’s total population (Castro and Heller, 2009). There are lots of problems connected with water shortage. One of the main problems is that in the situation with water scarcity the government decided to pump water from aquifers. For example, Mexico City is provided with water by six aquifers (UNESCO, 2006). The consequences of pumping groundwater resources are quite negative: aquifers are overexploited and they are drying, and ground is sinking for 40 cm every year (UNESCO, 2006). It is obvious that water shortage is a serious problem and effective measures must be taken in order to prevent water crisis.
It is also one of the country’s biggest users of ground water for irrigation. The valley has fertile soil but receives relatively little rainfall. Farmers in the area have been pumping up groundwater for growing their crops for around a century, and the aquifers have been being depleted are a rate far beyond their capacity to be replenished. Scientists estimate that about 15% of the water has been extracted, but that water took many thousands of years to get there.
The few rivers and lakes that exist do not contain a sufficient supply of water to meet the demand of the populace. This requires the majority of the water that is supplied to come from groundwater. Ground water is a series of aquifers, springs, and wells that store water beneath the surface. These underground water resources take time to accumulate because they are filled by surface runoff that has to seep through pores and crevices in soil, sands, and rock. In arid climates it takes even longer to accumulate because of the lack of precipitation each year. At the current rate of ground water pumping the water that is being pumped out of aquifers and springs is greater than it is replenished naturally. With population expected to grow in Tucson and around Arizona the groundwater depletion will only continue to
Water Drought and the Depletion of our Aquifers have lots to due with the human population growth in the World. The population is growing around 80 million people per year. Hence, we now need 64 billion cubic meters of water, per year for everyone in the World. With all the demand for water increases, we need to dig deeper into our wells. However, by digging deeper under the earth’s surface it is more likely to be contaminated with naturally occurring minerals, like radium that have been in contact with rock formations for hundreds of thousands of years with minerals that have dissolved into the water. Aquifers recharge so slowly soon wells will run dry, this is why we need to learn how to conserve water everyday.
Water What is something liquid and is used to create power? Water! Unlike coal and natural gas, water is a renewable resource. A renewable resource is a natural resource that can be replaced at which the resource is consumed.
When it comes to drinking water, most people immediately desire a crystal clear, ice cold bottle of water. What they might not know is that bottled water is dangerous; not only is it stored in a carcinogen-releasing container, but it has over 38 other chemicals and pollutants in it. Tap water, on the other hand, is straight from a source that is thoroughly regulated. Consumers should ban the bottle when it comes to drinking water and instead drink tap water. For one, drinking tap water decreases the astronomical amount of waste caused by bottled water. Not only that, but by American consumers purchasing bottled water, they are paying companies to waste money and valuable natural resources, while tap water and it's increased use is creating
To address the various nature of water management, we need to focus on the main issues relevant to water recourse management. There are both the positive and negative aspects of water. On the one hand, water is important to life. Water helps in production, agriculture, generation of hydropower, industries, fishing, tourism, transport. But on the other hand, water can be very destructive, carrying diseases and flooding vast areas. Insufficient water can result in deaths and economic decline. Water can also cause conflicts between communities in a local or national
