• Water securityFracking would pose no danger to water supplies: Research

    One of the primary concerns of those who oppose the development of shale gas by hydraulic fracturing is that creation of new fractures in the earth could cause fracking fluids to leak into, and contaminate, underground freshwater aquifers. Potential future fracking activity in the United Kingdom is unlikely to pose a pollution danger to overlying aquifers, new research from a leading academic suggests.

  • Water securityGroundwater quality changes alongside the expansion of hydraulic fracturing and horizontal drilling

    New research demonstrates that groundwater quality changes alongside the expansion of horizontal drilling and hydraulic fracturing but also suggests that some potentially hazardous effects may dissipate over time. The research is the first to analyze groundwater quality in the Cline Shale region of West Texas before, during, and after the expansion of hydraulic fracturing and horizontal drilling.

  • Water securityNew way to clean contaminated groundwater

    A team of researchers has helped discover a new chemical method to immobilize uranium in contaminated groundwater, which could lead to more precise and successful water remediation efforts at former nuclear sites. Uranium is present in contaminated groundwater at various sites in the United States as a legacy of Cold War-era processing and waste disposal activities associated with nuclear materials production.

  • Water securityOil, gas wastewater disposal pollutes surface water, harm waterways

    Unconventional oil and gas (UOG) operations combine directional drilling and hydraulic fracturing, or “fracking,” to release natural gas and oil from underground rock. This process results in in water pollution which may increase endocrine disrupting chemicals (EDCs) in surface and ground water, exposing populations living near these operations to increased risk of disease. High levels of EDC activity were found in the surface water near a hydraulic fracturing wastewater disposal facility in West Virginia. Approximately 36,000 of these disposal wells are currently in operation across the United States.

  • Water securityWater cycle instability posing major political and economic risks: UN experts

    The current instability and unpredictability of the world water cycle is here to stay, making society’s adaptation to new risks a vital necessity when formulating development policies, a UN water expert warns. “What we haven’t understood until now is the extent to which the fundamental stability of our political structures and global economy are predicated on relative stability and predictability of the water cycle — that is, how much water becomes available in what part of the year. As a result of these new water-climate patterns, political stability and the stability of economies in most regions of the world are now at risk,” the expert says.

  • Water securityWater problems in Asia’s future?

    By Peter Dizikes

    Economic and population growth on top of climate change could lead to serious water shortages across a broad swath of Asia by the year 2050. Having run a large number of simulations of future scenarios, the researchers find that the median amounts of projected growth and climate change in the next thirty-five years in Asia would lead to about one billion more people becoming “water-stressed” compared to today.

  • Water securityQuantifying climate-driven impacts on the Colorado Basin, developing response strategies

    The Colorado basin — roughly 11 percent of the United States — directly supports water supply for more than thirty million people, accounts for approximately 15 percent of U.S. crops and livestock, and provides 53 gigawatts of power generation capacity. Climate-driven heat-stress and forest mortality on the Colorado River watershed are expected to reduce river flows basin-wide out to the year 2100.

  • Water securityFlorida’s Turkey Point nuke pollutes Biscayne Aquifer, Biscayne National Park

    Contaminated water originating from the cooling canal system at Florida Power & Light’s (FPL) Turkey Point facility is reaching Biscayne Bay, threatening South Florida’s drinking water supply and Biscayne National Park. The facility is one of Florida’s biggest daily water users and discharges at least 600,000 pounds of salt and other contaminants directly into the Biscayne Aquifer on a daily basis. The Biscayne Aquifer is a “sole source,” federally designated aquifer that serves more than three million people.

  • Water securityExpanding use of recycled water would benefit the environment, human health

    More than 1 in 9 people around the world, about 750 million, do not have access to safe, clean drinking water, and the problem is expected to worsen in step with rising greenhouse gas concentrations, population increases and climate change. Researchers found that found that recycled water has great potential for more efficient use in urban settings and to improve the overall resiliency of the water supply.

  • Public healthFEMA rejects Michigan governor's request for more Flint money

    The Federal Emergency Management Agency (FEMA) has again rejected a request from Michigan governor Rick Snyder for additional federal assistance to address the lead poisoning in Flint, Michigan’s water supply. The contamination disaster was caused by a Snyder-appointed city manager’s decision to shut down the city’s access to water filtration systems as a cost-cutting measure.

  • Water securityFertilizer applied to fields today will contaminate water for decades

    Nitrogen fertilizer applied to farmers’ fields has been contaminating rivers and lakes and leaching into drinking water wells for more than eighty years. Dangerous nitrate levels in drinking water could persist for decades, increasing the risk for blue baby syndrome and other serious health concerns.

  • Water securityWarmer spring temperatures reduce Colorado River flows

    Warmer-than-average spring temperatures reduce upper Colorado River flows more than previously recognized, according to a new report. The study, the first to examine the instrumental historical record, discovers that temperature has played a larger role in streamflow and in exacerbating drought since the 1980s.

  • Water securityGroundwater deficit growing in important western U.S. aquifers

    By 2050, climate change will increase the groundwater deficit even more for four economically important aquifers in the Western United States, a new report says. Groundwater deficits are expected to worsen in four important aquifers, creating a precarious balance between usage and recharge. The new report is the first to integrate scientists’ knowledge about groundwater in the American West with scientific models that show how climate change will affect the region.

  • Water securityWater storage strategies in Sub-Sahara Africa

    Direct abstraction of water from rivers through ponds and pumping devices seems the most attractive water storage option in Ethiopia. However, the funding agencies that may be interested in investing in such a storage system have to consider that better access to credit, and clear abstraction policies should be ensured.

  • WaterChlorine-free water tastes better, and may be healthier

    Chlorinated tap water is the norm around the world, but the experiences of several European countries is that it does not have to be. The benefits of foregoing chlorine include better-tasting and, potentially, healthier water.
