Recommended: Effects of groundwater pollution
Due to its extraordinarily high quality and availability, we take groundwater as an advantage and now we experience groundwater management problems all over the world. Ground water contributes worldwide about twenty percent of people’s fresh water (Kinzelbach, Bauer, Siegfried, and Brunner). Groundwater is considered the most suitable for drinking, but we didn’t realize that over pumping ground water could be vulnerable to degradation, which leads to drying wetlands, deterioration in water quality, and increasing salinization. As groundwater cannot be renewed artificially on a large scale, sustainable management of this resource is vital (Kinzelbach, et al.). For groundwater to recharge itself, it would depend on precipitation because it is the main source for creating ground water and it is something out of our control. We experience groundwater depletion due to excessive pumping of an aquifer and this results in degradation of water quality, impacting natural wetlands, and affecting drinking water from contamination, in order to recharge groundwater, we would need to understand what would be impacted, scientific tools to help assist in groundwater sustainability management, and different techniques that we could use to artificially recharge groundwater.
Groundwater depletion occurs when we over pump an aquifer causing degradation in water quality. This can impact our drinking water systems, economic stability, and groundwater level tables. Groundwater originates from precipitation from our water cycle and is divided into two different types of groundwater flow; there are shallow groundwater flow and deep groundwater flow. Shallow groundwater flow also known as groundwater runoff, diverts onto land surfaces and flows back int...

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

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 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.
