    sinkholes form when the land surface above collapses into subsurface voids. According to Younger (2007), “Natural subsidence is a widespread consequence of the collapse of subsurface voids, which in turn owe their existence to the erosive action of groundwaters” (p.178). While all sinkholes share the same characteristic of a surface depression, the origin of this depression can be

    Establishment of Managed Aquifer recover (MAR) System 1. Introduction 2.1. Managed Aquifer Recovery Systems As reported by the South Australian local government of Charles Sturt (2012), Aquifer Storage and Recovery (ASR) or Managed Aquifer Recharge (MAR) is essentially the deliberate storage of surface water (i.e. in the form of stormwater, treated effluent etc) within aquifers. This process is used where water is pumped into aquifers for future usage. Furthermore, MAR systems avoid the need

    the treatment process to reduce the risk of re-contamination in the distribution system. Many environmental and cost considerations affect the location and design of water purification plants. Groundwater is cheaper to treat, but aquifers usually have limited output and can take thousands of years to recharge. Surface water sources should be carefully monitored for the presence of unusual types or levels of microbial/disease causing contaminants. The treatment plant itself must be kept secure from

    and yet, it’s depleting at a faster rate than what can be replenished. According to Kally Worm “Groundwater is the second largest reserve of freshwater on earth. It also makes up 40% of the freshwater used in the U.S. alone.” This ground water is usually found in what is called an aquifer. An aquifer is found towards the lower layers of the soil. The problem with these aquifers it that their recharge rate is slow making it non- renewable. These water supplies being non- re We are overusing these

    a flowing body of ground water at or below the local water table, below which the subsurface material is saturated with water. (Perlman, 2011) They can live inside any type of rock. The springs held within the Grand Canyon discharges groundwater, and this groundwater supplies drinking water to the Canyon’s visitors, Flagstaff, the Coconino Plateau, etc. The Grand Canyon will continue to change over time. However, it is uncertain as to what continued acts of weathering and mass wasting will do to

    feet in thickness. To meet farming demands, the site is artificially drained. Groundwater flows to the Oak Orchard Creek in the northwest, away from the esker, which is highland in southern part of the property. The site is adjacent to wooded areas and farms, and the soils are extremely highly organic in fact, which has been classified as prime agricultural land by the state. When it comes to resource use, groundwater is employed as an alternative water supply for life consumption as

    Case Summary According to research conducted by the United Nations, approximately two-thirds of the world’s population will face a severe shortage of water by 2025(Shaw & Barry, 2014, pg. 131). Some countries have begun to prepare early by importing tankers of water from other countries. The State of Michigan; however, is not as concerned about the shortage due to having over 11,000 lakes including the Great Lakes. Due to the vast amount of water sources, Nestle has built a bottled water plant in
