However, after nearly sixty years of intense use of the Ogallala Aquifer, it is now a source of great apprehension as the aquifer shrinks, and the main source of water in the Great Plains area disappears. All these species and life forms are dependent on groundwater. However, regions within Arizona can be designated as Irrigation Non-Expansion Areas (INAs) or Active Management Areas (AMAs). complete answer on waterencyclopedia.com, View So while there are many sources of recharge, discussed above, all contributing a small amount of water, there are two main natural barriers to recharge: lack of ground permeability and high evaporation rates. Web. It explores how long the Ogallala Aquifer is expected to survive with and without conservation practices. McElroy, Anduin K. The Future of the Ogallala Aquifer. Ethanol Producer Magazine The Latest News and Data About Ethanol Production. These programs offer economic incentives and aid for both private and public properties. This vicious cycle will accelerate the rate of depletion. Manmade sources may be characterized as point sources, where the contaminants can be traced to a particular location, and non-point sources, where contaminants accumulate over a large, more vaguely defined area. Many of the states contain water meter policies and strict regulations on the amount of water each household can use. Since these species have such a narrow range of tolerance for water table changes, any decrease in water table can result in a decrease in biodiversity of the ecosystem. Multistate Project Focused on Protecting One of Nation's Largest Examples of point sources include leaky tanks or pipelines containing petroleum products, septic systems and industrial waste (Environment Canada, 2008). It occupies an area of 174,000 square miles, spreading across 8 American Great Plains States, according to the US Geological Survey. Water pumped for irrigation from the Ogallala Aquifer is the principal driver of the region's mostly agricultural-based economy (market value $35 billion) Unfortunately, intensive irrigated agriculture is draining the aquifer much faster than rainfall can replenish it. It tries to improve water quality, ecosystem condition and levee stability in the Delta-Bay region ("CALFED"). In Kansas, irrigation accounts for 84% of water usage, while municipal usage is at 11% and industrial usage is only at 3% (Durban, 2011). This will lead to ultimate depletion of the Ogallala Aquifer. The main barrier to recharging the Ogallala Aquifer is lack of permeability. Pumping underground water, he told his audience, would build little homes of pleasing architecture. Riparian ecosystems are generally found in the semi-arid or arid environments. Although the aqueduct would not have provided a permanent solution to halting the depletion of the aquifer, it would have slowed depletion by relieving some of its current pressures. N.p., n.d. As the heat rises, anxious irrigators gather to discuss whether and how they should adopt more stringent conservation measures. As a result, the responsibility of making key decisions on preserving this important resource fall to both the county and the state governments of these areas. Texas aquifer is running dry, jeopardizing agriculture industry | The On average, 350 mm (13.8 in) of rain falls in the southwest part of the Ogallala aquifer annually. Only the Colorado Ground Water Commission can issue or change permits. Since the 19th century, with the advent of electric pumping, there has been an increased exploitation of groundwater resources. These advances turned the Central Plains into the worlds breadbasket and meat market, annually generating $20 billion worth of foodstuffs. As much as 15% of irrigation water can permeate into the Ogallala Aquifer (Kansas Department of Agriculture, 2006). Farmers Deplete Fossil Water in World's Breadbaskets Annual recharge of the Ogallala Aquifer varies widely from region to region; however, the average annual recharge rate is .85 in/year, or 21.59 mm/year (U.S. Geological Survey, 1966). It sheds light on possible methods that can be used through modified crops to reduce the stresses on the Ogallala Aquifer. complete answer on nationalgeographic.com, View The Ogallala Aquifer Depletion - Iowa State University 1:04. The High Plains aquifer, also known as the Ogallala aquifer, is the largest aquifer in the United States. Some set specific depletion caps, others only say that water must go to "beneficial uses". It also contains information regarding its goals, and benefits that proposed conservation programs will help landowners. However, the fact that the aquifer spans across eight different states is problematic as it leads to disconnected management of the aquifer. Some rural homeowners may also use USTs for residential or farming purposes. Second, there will be a loss of biodiversity. One of the weaknesses is that the article doesnt explain its methods of research. Thus, overpumping groundwater and contamination from agricultural run-off has threatened the existence of these delicate systems. Many but not all states require permits for drilling and producing from wells; generally, wells for domestic purposes do not require a permit and go primarily unregulated. Basso, B., Hyndman, D., & Kendall, A. Can mold exposure cause autoimmune disease? The article and source are reliable as they use reliable sources such as Science journal. Business. Most of the groundwater is found below the Rosebud Indian Reservation land. In order to have a unified, cohesive strategy, we suggest the below methods of management. The current drought is only adding to these woes. But as drought worsens, this may be easier said than done. It turned once perennial rivers into ephemeral. Nebraska, Texas, and Kansas use the highest percentage of groundwater for their irrigation (46%, 30%, and 14% respectively) (Kromm, 2007). Ogallala Aquifer dropped 12+ inches in 2021. Land value could lose The state Engineer is in charge of overseeing the well drilling process (Water Rights Fact Sheet, 2001). The 2.5% taken for domestic drinking water as well as the amounts taken for mining, livestock, and industry (1.3%, 1.3%, and .9% respectively) are small in comparison (U.S. Geological Survey, 2008). Coexisting with this conflict, is the lack of scientific solutions to reduce pressures on the aquifer and achieve sustainability or long term conservation. This land accounts for 27% of the nation's irrigated land and is responsible for 19% of the nation's wheat, 19% of its cotton, 15% of its corn, and 3% of its sorghum. 2 Nov. 2015. Although this report doesnt directly critically examine the relationship between the economy and Ogallala Aquifer, it brings forward some key points regarding the economy and the impacts depleting and conserving the Ogallala could make. Eric Simpson, a farm manager in Lubbock, to the northwest of Texas, told The Texas Tribune that the Ogallala is "propping" up all the farmers. Currently, its thickness varies from less than 1 ft to about 400 ft (Miller, J. Once it has gone, it would take over 6,000 years to replenish naturally through rainfall. This publicly funded organization provides information on different geological hazards and their consequences. 1 a). 03 Nov. 2015. It is a source of quality water, due to the natural filtration process through the porous or semi-porous rock/soil layer above the aquifer and provides invaluable nutrients for the ecosystem. The Ogallala Aquifer is a massive store of groundwater that quenches the thirst of people, crops and livestock throughout the Great Plains. The Ogallala Aquifer serves farming communities in multiple states. The Ogallala aquifer is one of the world's largest fresh water resources. Do you have a tip on a science story that Newsweek should be covering? Kansas Ogallala Aquifer depletion among water quantity, quality issues 'Drought is on the verge of becoming the next pandemic' Which is more poisonous copperhead or cottonmouth? The withdrawal rate of water from the Ogallala Aquifer is much too high to be sustainable for the next one hundred years. The Wildlife Habitat Incentive Program develops and restores wildlife habitats, in addition to prioritizing the habitats for endangered wildlife. The Invasive Species Program specializes in controlling and preventing the invasion of foreign, exotic species into an ecosystem ("Invasive Species Program"). Landfills allow waste from households and domestic uses to permeate into the aquifers. Some observers blame this. Starting in the late 19th century, settler-colonists plowed up native grasses that protected the soil. Such differences of values are seen not just between groups but within them. This is a permanent commitment ("Wetlands Reserve Program"). However, water can be withdrawn once a permit has been approved. However, with such a great production from the Ogallala Aquifer region comes just as great a cost in water (U.S. Geological Survey, 2008). Hence, usually many of the contaminants end up in these ecosystems, harming the wildlife and the habitat. Whether these initiatives will become widespread, or can sustain agriculture on the Central Plains, is an open question. The State Engineer has the authority to grant permits. Texas farmers worry one of the state's most precious water resources is running dry. Little, Jane Braxton. Ogallala's groundwater feeds into springs that support wetlands, habitats for many species. What Happens When The Massive Ogallala Aquifer Becomes Depleted? This article is useful for our research because it shows that there is a direct correlation between the agricultural industry and economy and the Ogallala Aquifer. In many of the states, there are also policies in which landowners are required to obtain a permit before being allowed to withdraw water from the aquifer. A. it has become contaminated with radioactive waste from the Chernobyl accident B. precipitation is heavier to the east, causing tilting of the entire formation C. overpumping may cause southern parts of the aquifer to go dry in the next 100 years D. none of these Solution Riparian ecosystems are rich ecosystems that host a wide variety of species. And as the air heats up, it further desiccates the soil. Ogallala Aquifer Depletion is Causing High Plains Farmers to Conserve These invasive species have a higher tolerance for the decrease in groundwater and can better adapt to this environment. Even as they pursue efficiencies in irrigation, many are shifting from water-intense crops like cotton to wheat. Retrieved from http://www.nrcs.usda.gov/Internet/FSE_DOCUMENTS/stelprdb1048827.pdf. Another pressing issue that makes the Ogallala Aquifer a wicked problem is the conflicting laws seen in governance of the Ogallala Aquifer. There are six groundwater basins all governed by the State Engineer. In the words of Brent Rogers, a director of Kansas Groundwater Management District 4, there are too many straws in too small of a cup.. "No matter what, I'll probably have to use water from it this summer because, without that, I don't think we could grow much in West Texas unless it's a cactus or a mesquite tree," Simpson told the news outlet. NCA 2018 In Kansas, "Day Zero" - the day wells run dry - has arrived for about 30% of the aquifer. Why wouldn't it work elsewhere? This website helped explain the potential hazards related to ground subsidence a problem faced by people living in areas with a depleting aquifer. To put these numbers into perspective, the USGS estimates that the total amount of water in storage was 2,980 million acre-feet in 2000. Within these areas groundwater use is restricted and certain users have priority, regardless of when their pump was established (Water Rights Fact Sheet, 2001). The Kansas City Star, 24 July 2015. Plants, such as juvenile Salix Gooddingii, juvenile Populus Fremontii, juvenile Fraxinus Velutina, only have a range of about 1.8m change in depth to groundwater. This government document outlines the different water withdrawal regulations regarding the Ogallala Aquifer. Efforts are underway to turn this problem around. In areas where there is not NDNR governance, residents follow the Nebraska correlative rights doctrine that states that residents must share when groundwater supplies are limiting (McGuire et al, 2000, 40). Permits are not required for wells using less than 35 gal/min and wells that do not exceed 10 acre-ft per year. To change a permit "requires that the well be limited to the average annual historical consumptive use and proof that no material injury will occur to other vested water rights" (McGuire et al, 2000, 37). The former and current president both shared Independence Day messages on social media on Tuesday. Drought pushes the limits of irrigation. Rapidly dropping reservoir levels in the West are capturing national media attention, but the nation's underground aquifers are also under threat. Darton of the U.S. Geological Survey located the first outlines of the aquifer near Ogallala, Nebraska. Retrieved from, Sources of Contamination: Point Sources and Non-Point Sources, Environmental Effects of Groundwater Depletion, Current Public Policy Regarding Groundwater, State Policies For Groundwater Withdrawals, Better Water Quality - High Vulnerability, Less Serious Water Quality Problems - Low Vulnerability, Less Serious Water Quality Problems - High Vulnerability, More Serious Water Quality Problems - Low Vulnerability, More Serious Water Quality Problems - High Vulnerability. The Washington Post, 12 Sept. 2013. Here we see that choices are being made so that the economy benefits causing the aquifer to deplete. Motor fuel contains hydrocarbons and additives that pose health risks to people, animals, and plants. The main way to save the underwater lake is to restrict water use. N.p., n.d. In my view, Plains farmers cannot afford to continue pushing land and water resources beyond their limits especially in light of climate changes cumulative impact on the Central Plains. Depleting the Ogallala Aquifer | EarthDate What about a body of water that's locked away . Farmers who are depleting other aquifers in Latin America, eastern Europe, the Middle East, and Asia could face similar choices. Situated under the Great Plains of North America, the water from the Ogallala Aquifer was first extracted for use after the Second World War, and has been one of the most important freshwater resources for irrigation in the United States. The main issues regarding groundwater in the Western half of the United States are that: The depletion rate is much higher than the recharge rate. Wicked Environmental Problems. Google Books. These highly porous and permeable sands and gravels filled with water during times of much wetter climates such as ca 10,000 years ago. One group consists of farmers who support conservation, and have taken measures to reduce, and in some cases stop irrigation completely. Riparian ecosystems are land ecosystems found near moving water bodies, such as rivers and streams. The state is already suffering from drought and as the aquifer continues to decline, crops are at risk. That's the biggest single-year decrease since 2015, according to the Kansas Geological Survey's annual report.. And while the aquifer is losing that foot of water, it's barely being refilled. No. This graph clearly shows that the Ogallala Aquifer is being depleted, and if nothing is done to change current water pumping behavior, the Ogallala Aquifer will become extinct. There are riparian rights, appropriative rights, pueblo rights. Farming accounts for 94% of the groundwater use. How Long before the Great Plains Runs out of Water? Washington Post.
