    Simply collecting rainwater could save U.S. residents millions of dollars each year on their water bills and drastically cut down on water consumption; a new study by the Natural Resources Defense Council examined the potential cost-savings in eight U.S. cities and found that residents could collectively save $90 million or more annually

    Hydraulic fracturing (fracking) involves the high-pressure injection of water, sand and chemicals into a shale seam, which causes the rock to shatter, releasing natural gas; preliminary findings from a study on the use of hydraulic fracturing in shale gas development suggest no direct link to reports of groundwater contamination

  • Water

    A recent U.S. Geological Survey (USGS) study found that groundwater in aquifers on the East Coast and in the Central United States has the highest risk of contamination from radium, a naturally occurring radioactive element and known carcinogen

    Photocatalysis involves the acceleration of chemical reactions using the power of light; researchers experiment with different types of photocatalysts to reduce nitrates in water

  • Infrastructure protection

    A recent Government Accountability Office (GAO) report found that the bulk of U.S. critical infrastructure is inadequately protected as operators lack a coherent set of guidelines

  • Water

    The UN estimates that about 1.1 billion people currently lack access to safe water; forecasts suggest that freshwater may become the “oil” of the twenty-first century — expensive, scarce, and the cause of geo-political conflicts; scientists show a new method for purifying water

  • Water

    Biologists and bioengineers at UC San Diego have created a living neon sign composed of millions of bacterial cells that periodically fluoresce in unison like blinking light bulbs; because bacteria are sensitive to many kinds of environmental pollutants and organisms, the scientists believe this approach could be used to design low cost bacterial biosensors capable of detecting an array of heavy metal pollutants and disease-causing organisms

  • Water

    Intensive agriculture practices developed during the past century have helped improve food security for many people but have also added to nitrate pollution in surface and ground waters

  • Water

    Engineers at Brown University have developed a system that cleanly and efficiently removes trace heavy metals from water; in experiments, the researchers showed the system reduced cadmium, copper, and nickel concentrations, returning contaminated water to near or below federally acceptable standards; the technique is scalable and has viable commercial applications, especially in the environmental remediation and metal recovery fields

  • Water security

    Aside from possible cyberatacks on water utilities, security officials are worried that terrorists could contaminate water supplies with volatile chemicals that can poison thousands of individuals and even cause explosions; DHS warned local water utilities of “backpressure” — a simple tactic terrorists could use to introduce a chemical or biological agent into the water supply and spread it over long distances without immediate detection

  • Water

    Researchers are working to develop a portable wastewater treatment system that could improve the military’s efficiency; the solar-bio-nano project also will generate energy and produce drinking water, thus providing a potential blueprint for the future of municipal/agricultural wastewater treatment systems

  • Infrastructure protection

    DHS agents and local authorities in New Jersey are investigating a series of attacks on the West Milford water system; since July there have been more than fifteen attacks on local water and sewage facilities that in some instances have resulted in sewage flooding the street or losses in service all together

  • Sterilizing water

    Scientists show that ionized plasmas like those in neon lights and plasma TVs not only can sterilize water, but make it antimicrobial; these plasma devices could be life-savers in developing countries, disaster areas, or on the battlefield where sterile water for medical use is in short supply and expensive to produce

  • Water

    Scientists have developed a revolutionary ultrasonic attachment for taps, which massively enhances the ability of water to clean; currently, industry uses excessive water, power, and additives for cleaning

  • Water

    A simple method converts waste glass into a material which can be used to remove pollutants from contaminated water; the method uses colored glass which is being stockpiled in the United Kingdom as there is less recycling demand for green and brown bottles than there is for clear bottles

  • Water

    Well diggers in Bangladesh will soon be able to take advantage of a cell phone-based data system, developed at the Earth Institute, to target safe groundwater aquifers for installing new wells that are not tainted with arsenic

  • Water

    Drinking water taken from a deep aquifer protected by a semi-permeable layer of rock should be safe because the water is protected from many contaminants, including viruses — but is it safe? University of Wisconsin scientists find virus particles in many deep Madison, Wisconsin water wells, raising questions about how viruses, which should not survive more than two years underground, reached so deep and survive for so long

  • Water

    More than 800 million people around the world lack access to clean water; the water available for people to drink in many developing countries has not been treated to remove contaminants, including pathogenic microorganisms; half of the world’s hospital beds are occupied by people who are sickened by the water they drink; Purdue University researchers have invented a water-disinfection system that uses the sun’s ultraviolet radiation to inactivate waterborne pathogens

    Analysts are predicting that the global market for water could grow dramatically over the next two decades, with some projecting a $1 trillion market in 2020; “Water is the fastest growing market at the moment, with a size of $500 billion globally,” said Harri Kerminen, the president and CEO of Finnish chemical firm Kemira
