Understanding this footprint is especially important because global studies have shown that many economically active regions already are experiencing moderate to severe water stress, with withdrawals from rivers, lakes, and aquifers approaching or exceeding sustainable limits. In the United States, self-supplied withdrawals from surface and ...
A recent study found that one in five water wells are at risk. Solutions like water reuse and desalination can help preserve endangered aquifers. A new study in the journal Science reports that up to 20% of groundwater wells around the world are in danger of running dry mainly due to overpumping and drought. That’s a concerning number because half of the world’s drinking water and ...
With such development, it’s no wonder that the City of Sugar Land needed a better way to provide potable water to support the population while reducing dependence on the existing groundwater withdrawal method that had been contributing to flooding problems in the region. In fact, the Fort Bend Subsidence District mandated reduction of ...
Satellite data is used to minutely track ground levels In California each year, massive groundwater withdrawals for agriculture, industry, and public use lead to aquifer compaction as groundwater becomes depleted. ...
This accounted for 1% of total U.S. water withdrawals. More than 70% of mining withdrawals came from groundwater sources, 65% of which were saline; 77% of the surface water used was fresh water. ...

Eight were overstressed with negligible recharge, and five more were highly stressed and still being pumped, but with some recharge occurring. The biggest culprit for groundwater depletion was agriculture, and the depletion problem was amplified by drought conditions such as those observed in California in recent years. ...
In late 2017, it reached an agreement to grant groundwater withdrawal permits to two of the state’s largest industrial groundwater users — WestRock paper mill in West Point and International Paper’s Franklin mill — that mandate pumping cuts of up to 52%. The WestRock mill, the largest groundwater user in ...
In times of drought or water scarcity, little water is available naturally to recharge existing groundwater supplies, which can become depleted by overuse. Groundwater withdrawals have tripled in the past 50 years, according to 2012 United Nations estimates cited in The World’s Water: Volume 8. Areas with the highest ...
Groundwater decline poses a significant sustainability challenge in arid and semi-arid areas where groundwater plays a major life sustaining role. Recent years have marked a drastic decrease in the groundwater table (about 1.1 m/yr equivalent to 19.3 million cubic metres) in the Firuzabad Plain, Iran, where policies to restore ...
The cumulative effects of 40 years of groundwater withdrawals in the Houston-Galveston region are documented in a report from the United States Geological Survey. ...
Changes in rainfall may be responsible for reducing groundwater storage in India more than withdrawals for agricultural irrigation, according to a recently published analysis. ...
It provides groundwater flow simulations for the period “before substantial groundwater withdrawals” and the period from May 1940 through April 2009, when groundwater withdrawals increased. ...
Traditionally, the common law of water rights in Michigan embraces the riparian doctrine for surface water and provides landowners with the right to use groundwater. However, two recent changes in common and statutory law significantly modify the legal relations among water users and others with a stake in water use decisions. A 2005 Michigan Court of Appeals decision created a ...
Shallow tropical coastlines harbour unique mangrove ecosystems, which support livelihoods and provide a natural barrier against coastal flooding. Non-sustainable land-use practices, such as large-scale clear cutting of mangroves for aquaculture, ground water withdrawal and alteration of river flows, result in rapid subsidence. The collapse of aquaculture production, due to pollution and disease, ...
Groundwater salinization is an ever increasing problem in coastal aquifers due to seawater intrusion resulting from excessive groundwater withdrawals, lithological conditions of the aquifer and industrial and agriculture pollutant loads. ...
Borough of Dublin, Bucks County Hydrogeological Consultant of Record Mercuri and Associates, Inc. was contracted to conduct the necessary hydrogeologic study to identify and recommend test well sites to augment the available water supply. Study was completed on time and on budget and resulted in the identification of eight sites with the potential for good well yields. MAI conducts regular ...
The present study employs regional climate model projections for assessing the impact of root-zone water balance and groundwater levels using crop and groundwater models. The projections from Hadley Regional Model 3 (HRM3) for A1B scenario showed an increase in temperature and rainfall (RF) of 1.8 °C and 328 mm, respectively, during mid-century (MC) ...
A generalized hierarchical approach with a water balance function is introduced to simulate stream-flow depletion in a complex groundwater system in Osceola County. The groundwater flow system at the site, because of the complex interaction between ambient streams, exhibits a unique multi-scale pattern that proves to be difficult to simulate using standard ...
In August, the California legislature passed a package of laws to regulate groundwater pumping for the first time in state history. But the laws won’t slow damage to aquifers without meaningful limits on groundwater withdrawals or a charge for extraction, says Zetland, the water economist. ...
