Well Well Well activity. Groundwater is Cool. Pumped Dry: The Global Crisis of Vanishing Groundwater - Desert Sun. A drying shame: With the Ogallala Aquifer in peril, the days of irrigation for western Kansas seem numbered. The prairie wind buffeted Brant Peterson as he stood in a half-dead field of winter wheat. In front of him, a red-winged blackbird darted in and out of a rippling green sea of healthy wheat. Behind him, yellowed stalks rotted in the ground. The reason for the stark contrast was buried 600 feet under Peterson’s dusty boots: Only part of the field — the thriving part — had been irrigated by water pumped at that depth from the ancient Ogallala Aquifer, one of the largest underground sources of fresh water in the world.

“If not for irrigation, that whole field would look like this,” Peterson said, nudging the dead wheat with the toe of his boot. But irrigation soon could end on Peterson’s southwest Kansas farm. The wells under his land in Stanton County are fast running dry as farmers and ranchers across the Great Plains pump the Ogallala faster than it can be replenished naturally.

Three of his wells are already dry. Western Kansas’ only significant water source is the Ogallala. Now Gov. Gov. Pumped beyond limits, many U.S. aquifers in decline. SUBLETTE, Kansas – Just before 3 a.m., Jay Garetson’s phone buzzed on the bedside table. He picked it up and read the text: “Low Pressure Alert.” He felt a jolt of stress and his chest tightened. He dreaded what that automated message probably meant: With the water table dropping, another well on his family’s farm was starting to suck air. The Garetson family has been farming in the plains of southwestern Kansas for four generations, since 1902. Now they face a hard reality. At dawn, Jay was out among the cornfields at the well, trying to diagnose the problem. “It’s showing signs of weakening,” he said sadly, standing in the shoulder-high corn. “This’ll last another five or 10 years, but not even at the production rate that we’re at here today,” he said.

Time is running out for portions of the High Plains Aquifer, which lies beneath eight states from South Dakota to Texas and is the lifeblood of one of the world’s most productive farming economies. Average decrease in water level 15ft. Soil Properties that affect Groundwater. Porosity The shape and arrangement of soil particles help determine porosity. Porosity or pore space is the amount of air space or void space between soil particles. Infiltration, groundwater movement, and storage occur in these void spaces.

The porosity of soil or geologic materials is the ratio of the volume of pore space in a unit of material to the total volume of material. A mathematical equation of porosity looks like this: Porosity or n=Vvoid / Vtotal. The arrangement or packing of the soil particles plays a role in porosity. What could happen when smaller particles are mixed with larger particles? Not all particles are spheres or round. One important point to remember is that the diameter size of the grain does not affect porosity. April: Soils Clean and Capture Water. Water Movement in Soil. Groundwater Contamination.

USGS Groundwater Depletion study of Aquifer decline in the United States | Peak Energy & Resources, Climate Change, and the Preservation of Knowledge. The Ogallala aquifer and other aquifers produce about one-third of america’s corn, wheat, alfalfa and other crops that feed both people and animals. They are being depleted rapidly and most wont’ be recharged until after the next ice age. According to the USGS Groundwater Depletion in the United States 1900-2008: Groundwater depletion in the United States between 1900–2008 was 240 cubic miles (1,000 cubic km3).That’s twice as much water in Lake Erie (480 km3).For many areas the rate is unsustainableThis rate increased dramatically after 1950The consumption rate nearly tripled from 2000-2008 over past rates.

Some of this was due to drought and decreased snowmelt.In 2000-2008 about 25% of all water taken during the previous century was removed.

Montana's Ground-Water Information Center (GWIC) | Project Data | V.11.2016. Issue Similar to streamflow and precipitation data, ground-water level and water-quality measurements must be collected over long periods of time to be useful. Long-term data allow managers and others to determine normal water levels in wells, changes in water levels relative to climatic conditions, responses of water levels to development, and long-term water-quality trends. Objective Create a network of water wells from which water-level and water-quality data can be collected and that will provide information on most areas and aquifers in Montana.

Approach Strategically located water wells are periodically measured for water levels and sampled for water quality.

Sustainability: Water - The Ogallala Aquifer. USGS Fact Sheet 2009-3057: California’s Central Valley Groundwater Study: A Powerful New Tool to Assess Water Resources in California’s Central Valley. Competition for water resources is growing throughout California, particularly in the Central Valley. Since 1980, the Central Valley’s population has nearly doubled to 3.8 million people. It is expected to increase to 6 million by 2020.

Statewide population growth, anticipated reductions in Colorado River water deliveries, drought, and the ecological crisis in the Sacramento–San Joaquin Delta have created an intense demand for water. Tools and information can be used to help manage the Central Valley aquifer system, an important State and national resource. The U.S. The USGS Groundwater Resources Program funded this study, one of 30 regional aquifer studies the USGS is conducting to assess the Nation’s groundwater availability. In order to complete the study, the USGS developed an extensive, detailed three-dimensional (3D) computer model of the hydrologic system of the Central Valley (Faunt, 2009).

The Central Valley Hydrologic Model Model Features Farm Process Geospatial Database Results. New NASA data show how the world is running out of water. If You Think the Water Crisis Can't Get Worse, Wait Until the Aquifers Are Drained. Aquifers provide us freshwater that makes up for surface water lost from drought-depleted lakes, rivers, and reservoirs. We are drawing down these hidden, mostly nonrenewable groundwater supplies at unsustainable rates in the western United States and in several dry regions globally, threatening our future.

We are at our best when we can see a threat or challenge ahead. If flood waters are rising, an enemy is rushing at us, or a highway exit appears just ahead of a traffic jam, we see the looming crisis and respond. We are not as adept when threats—or threatened resources—are invisible. Groundwater comes from aquifers—spongelike gravel and sand-filled underground reservoirs—and we see this water only when it flows from springs and wells. A severe drought in California—now approaching four years long—has depleted snowpacks, rivers, and lakes, and groundwater use has soared to make up the shortfall. In most years, aquifers recharge as rainfall and streamflow seep into unpaved ground. The Ogallala Aquifer: Saving a Vital U.S. Water Source. On America’s high plains, crops in early summer stretch to the horizon: field after verdant field of corn, sorghum, soybeans, wheat and cotton. Framed by immense skies now blue, now scarlet-streaked, this 800-mile expanse of agriculture looks like it could go on forever.

It can’t. The Ogallala Aquifer, the vast underground reservoir that gives life to these fields, is disappearing. In some places, the groundwater is already gone. This is the breadbasket of America—the region that supplies at least one fifth of the total annual U.S. agricultural harvest. The challenge of the Ogallala is how to manage human demands on the layer of water that sprawls underneath parts of eight states from South Dakota to Texas.

High Plains farmers were blissfully unaware a generation ago that a dilemma was already unfolding. And they did. Today his community in southern Kansas, 180 miles west of Wichita, is one of the High Plains areas hardest hit by the aquifer’s decline. Groundwater depletion, USGS water science. Groundwater is a valuable resource both in the United States and throughout the world. Where surface water, such as lakes and rivers, are scarce or inaccessible, groundwater supplies many of the hydrologic needs of people everywhere. In the United States. It is the source of drinking water for about half the total population and nearly all of the rural population, and it provides over 50 billion gallons per day for agricultural needs. Groundwater depletion, a term often defined as long-term water-level declines caused by sustained groundwater pumping, is a key issue associated with groundwater use.

Many areas of the United States are experiencing groundwater depletion. Excessive pumping can overdraw the groundwater "bank account" The water stored in the ground can be compared to money kept in a bank account. Drying up of wells reduction of water in streams and lakes deterioration of water quality increased pumping costs land subsidence What are some effects of groundwater depletion? Water Data Library - Groundwater Level Reports. Study: Third of Big Groundwater Basins in Distress. About one third of Earth's largest groundwater basins are being rapidly depleted by human consumption, despite having little accurate data about how much water remains in them, according to two new studies led by the University of California, Irvine (UCI), using data from NASA's Gravity Recovery and Climate Experiment (GRACE) satellites. This means that significant segments of Earth's population are consuming groundwater quickly without knowing when it might run out, the researchers conclude.

The findings are published today in Water Resources Research. "Available physical and chemical measurements are simply insufficient," said UCI professor and principal investigator Jay Famiglietti, who is also the senior water scientist at NASA's Jet Propulsion Laboratory in Pasadena, California. "Given how quickly we are consuming the world's groundwater reserves, we need a coordinated global effort to determine how much is left.

" "We don't actually know how much is stored in each of these aquifers. Episode 640: The Bottom Of The Well : Planet Money. Pistachio trees in California's drought-stricken Central Valley.
