  • Combining economic policy instruments with desalinisation to reduce overdraft in the Spanish Alto Guadalentín aquifer

    This paper analyses the cost-effectiveness of combining several economic policy instruments to address the problem of non-renewable pumping in the Alto Guadalentín aquifer in southeastern Spain, one of the most extreme cases of aquifer depletion in Europe. Our results show that all instruments have significant economic impacts. However, the future availability of desalinisation would notably ...

  • Depleting groundwater – an opportunity for flood storage? A case study from part of the Ganges River basin, India

    Storing excess rainwater underground can become key in mitigating the frequency and magnitude of flood events. In this context, assessment of depleted groundwater storage that can be refilled in water surplus periods is imperative. The study uses Gravity Recovery and Climate Experiment (GRACE) data to identify variations in groundwater storage in the monsoonal Ramganga River basin (tributary ...

  • California Focusing on Groundwater Recharge

    Depleted aquifers provide storage for surplus precipitation during wet seasons “The effects of climate change are necessitating wholesale changes in how water is managed in California,” announced the state’s Department of ...

  • Falling water tables` knock-on effect on falling harvests

    Scores of countries are overpumping aquifers as they struggle to satisfy their growing water needs. The drilling of millions of irrigation wells has pushed water withdrawals beyond recharge rates, in effect leading to groundwater mining. The failure of governments to limit pumping to the sustainable yield of aquifers means that water tables are now falling in countries that contain more than half ...

  • How food production impacts global groundwater supplies

    The ever-increasing global trade in food is accelerating groundwater depletion in many areas of the world, emptying aquifers faster than they can be naturally recharged, according to newly released research. Although groundwater depletion is a well-known and frequently studied issue, the new research focuses on how groundwater supplies are affected by international trade. Agricultural ...

  • The rising tide of environmental refugees

    Our early twenty-first century civilization is being squeezed between advancing deserts and rising seas. Measured by the biologically productive land area that can support human habitation, the earth is shrinking. Mounting population densities, once generated solely by population growth, are now also fueled by the relentless advance of deserts and may soon be affected by the projected rise in sea ...

  • What is an Aquifer?

    Aquifers are natural formations that store groundwater, but these vital structures are threatened The word “aquifer” means “water bearer.” In the context of hydrogeology, it refers to a natural underground formation of permeable ...

  • Undersea storage for US carbon emissions

    Researchers are working hard on methods to mitigate, reduce or compensate for CO2 emissions. One of these, geological carbon sequestration, involves injecting CO2 into deep saline aquifers, or depleted oil and gas reservoirs so that it is not released into the atmosphere where it contributes to global warming. Now US researchers have found a potential new location for undersea CO2 storage, which ...

  • Greenhouse Gas Accounting Framework for Carbon Capture and Storage Projects

    Foreword Meeting the global challenge to reduce greenhouse gas (GHG) emissions and avoid dangerous climate impacts requires deploying a portfolio of emission reduction technologies. We must both commit to broad and deep efficiencies in the way our societies’ consume energy and to significant increases in power supplies from low carbon energy sources. At the same time, it ...

  • Who used your water yesterday?

    The answer to the question above boils down to numbers in the final analysis. With more than half of the world's population already based in urban areas the additional demand for core services such as water is overtaxing capacities for water supply and disposal in many of the world's larger cities. And the problem is only going to get worse. The proportion of the world's population that will be ...

  • Americans Drilling Deeper for Groundwater

    The practice is widespread, but ultimately unsustainable Researchers from the University of California, Santa Barbara have completed an ambitious analysis of decades of data on 11.8 million water wells in the United States and determined that Americans are drilling deeper for groundwater than ever before. They focused on ...

  • Getting the Market to Tell the Truth

    Moving the global economy off its current decline-and-collapse path depends on reaching four goals: stabilizing climate, stabilizing population, eradicating poverty, and restoring the economy’s natural support systems. These goals--comprising what the Earth Policy Institute calls “Plan B” to save civilization--are mutually dependent. All are essential to feeding the ...

  • Generalization and formalization of the US EPA procedure for design of treated wastewater aquifer recharge basins: II. Retrofit of Souhil Wadi (Nabeul, Tunisia) pilot plant

    The ‘Cap Bon’ peninsula in Tunisia suffers from intensive tourist activities, high demographic increase and industrial development. As groundwater had been for a long time the main water source, aquifers had been subject to a severe depletion and seawater intrusion. Despite the measures taken prohibiting new drillings and water carrying by the construction of a waterway linking the ...

  • Our global Ponzi economy

    Our mismanaged world economy today has many of the characteristics of a Ponzi scheme. A Ponzi scheme takes payments from a broad base of investors and uses these to pay off returns. It creates the illusion that it is providing a highly attractive rate of return on investment as a result of savvy investment decisions when in fact these irresistibly high earnings are in part the result of consuming ...

  • Stanford Researchers Link Aquifer Overdraft to Arsenic Contamination

    In a recent study, researchers used satellite data to establish a link between excessive pumping from California aquifers and dangerous arsenic concentration spikes in the groundwater of the Tulare Basin. This promises to be an important early warning system for the growing problem of arsenic contamination, which potentially threatens ...

  • Managed Aquifer Recharge

    As water demand increases, recycled water can be used to maintain groundwater levels In recent years, groundwater stored in key aquifers has become rapidly depleted. This is due not only to demand, but also to technological advances — notably the introduction of the rotary drill in the 1880s and the submersible electric water pump in the 1960s — that have increased exploitation of ...

  • A critical assessment of groundwater governance in Tunisia

    More than 40% of irrigation water currently used in Tunisia is provided by groundwater aquifers, most of which are in a critical state of depletion due to its overexploitation during the last three decades. This paper provides a critical assessment of groundwater management in Tunisia based on interviews with key officials from central and regional administrations, in addition to ...

  • Twin Oaks Treatment Plant Case Study

    Population growth and federal water quality mandates are necessitating water providers across the country invest in new water treatment facilities. Shrinking water supplies are also demanding systems reevaluate how their “dirty” water is utilized. This is particularly true in the Southwest, where water scarcity and growth are nothing new. Northwest Pipe Company’s engineered ...
