Desalinization water - Groundwater - Transportation
Various ways can be used to supply water to these areas. For example, transporting water from relatively wet areas to arid areas was among the earliest solutions to the problem. However, as the problem gained in magnitude, the distance increased and thus increased the cost of transportation (Brown 2004, pg 38-74). For example, pipelines are used to supply water to many arid areas across the world. Other methods include tapping rainwater and using it in the dry seasons. For example, dams are constructed on seasonal rivers to trap rainwater and store it for future use (Starrett, 2009). The main setback with this technique is that due to the arid nature of these areas, rain is not reliable and sometimes takes years before a single drop. The high temperatures also increase the rate of loss to evaporation (Brown 2004, pg 38-74).
In contemporary times, pumping of ground water and desalinization has emerged as the best methods of providing arid areas with clean drinking water. This is because though the water table may be low, it is possible to get to it using modern technology (Brown 2004, pg 38-74). In addition, seawater is the most common resource in the world. However, sometimes ground water and lake water require to be desalinated before they can be considered safe for human consumption (Brown 2004, pg 38-74)
[...] Desalination The water quality is independent of any factor. For example, distillation ensures that desalinized water is free of any impurities. However, when used by human, distilled water has an unpleasant taste and lack some vital minerals (Becker 2013, pg 193-242) Conclusion and Recommendation In conclusion, all sources suggest that there is an increasing reliance on desalinization, not because of the cost, but because of the sheer abundance of salt water. Therefore, the cost should not be the biggest determinant of the preferred source of water because some factors are more influential. [...]
[...] Note that the biggest determinant of cost for ground water is distance. Generally, long distance transportation increases the costs and therefore the feasibility of pumping. Sometimes gravity may be used to pump water, but this argument is not feasible for several reasons. The first is that ground water is responsive to gravity and therefore tends to be available at the lowest elevation, implying that it is pumped from the lowest possible areas (Sehlke et al 107-165). Secondly, arid areas typically lie in low altitude areas. [...]
[...] In addition, seawater is the most common resource in the world. However, sometimes ground water and lake water require to be desalinated before they can be considered safe for human consumption (Brown 2004, pg 38-74) . The most affected deserts are ones where the population is growing at an unprecedented pace (Starrett, 2009). For example, due to the discovery of oil, there has been population explosion in Northern parts of the Sahara desert and in the Arabian Desert (Brown 2004, pg 38-74). [...]
[...] Desalinization water vs. groundwater 1. Introduction (generalization) Rising population has led to settlements in previously unsettled areas. In addition, the limited resources in these areas are unable to support the rising population. The result is that there is an increased need for water, especially in the arid areas (Starrett 2009, pg 45). This increase has resulted in an increased focus on a sustainable way to provide clean drinking water to the arid areas. This paper will examine possible ways to provide sustainable drinking water to arid areas Background Various ways can be used to supply water to these areas. [...]
[...] In addition, there are models that attempt to use solar energy. The process of reverse osmosis also seeks to reduce the costs of desalinization (Sehlke et al 107-165) Water Quality Groundwater pumping The quality of ground water is reliant on geological functions. For example, presence of salty rock material reduces the quality of ground water. However, these minerals are touted as good for bone development. However, they are sometimes harmful to plants and thus this water is sometimes unsuitable for agriculture (Becker 2013, pg 193-242). [...]
