    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

    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

    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

    Scientists at Kansas State University and seven other collaborating institutions were recently awarded $3.3 million from the National Science Foundation (NSF) to conduct a-large scale study of how stream organisms influence water quality across North America

    The head of the U.S. Cyber Command said that cyber attacks on the United States are escalating from large-scale theft and disruption of computer operations to more lethal attacks that destroy systems and physical equipment

  • Water

    South Florida’s water supply is becoming increasingly endangered by saltwater that is steadily seeping in from the ocean and contaminating supplies; despite the best efforts of local communities to stop the problem, saltwater intrusion is spreading

  • Infrastructure

    Engineers have pioneered new methods for detecting leaky pipes and identifying flood risks with technologies normally used for computer game graphics and Artificial Intelligence; these techniques could help to identify water supply and flooding problems more quickly than ever before

  • Water

    Almost 100 million people in developing countries are exposed to dangerously high levels of arsenic in their drinking water, unable to afford complex purification technology; scientists developed a simple, inexpensive method for removing arsenic based on chopped up pieces of ordinary plastic beverage bottles coated with a nutrient found in many foods and dietary supplements

    New research shows that wastewater recycling processes may generate more greenhouse gases than traditional water-treatment processes; still, there are good reasons to continue keep wastewater recycling among the water-resource tools for urban areas

  • Water

    Thermopower waves in thermoelectric materials can convert heat from solid fuels into electrical energy, in research that advances the vision of “smartdust” and other truly autonomous micro and nanomachines; “smartdust” systems are micro-electromechanical systems that are networked wirelessly for sensing and receiving data, for example testing pH of soil in large agricultural fields or quality of water reserves

  • Water

    A lot of the water we use daily goes to waste — whether it goes down drains, sewers, or toilets, much of it ends up at a wastewater treatment plant where it undergoes rigorous cleaning before it flows back to the environment; researchers are looking at processes which would turn wastewater into energy

    Parts of the Danish capital Copenhagen were without clean drinking water Saturday after high levels of the E.coli bacteria were detected in the municipal tap water system

    A fuel cell system that can generate electricity from organic compounds and clean up wastewater at the same time has been developed by scientists in China; the cell uses light energy to degrade organic compounds in wastewater, generating electrons that pass through to the cathode, which converts the chemical energy into electrical energy

    A third of the world’s population — more than two billion people — lives without access to clean drinking water, and studies show that the situation will only get worse; a French innovator has an idea: towing icebergs from the Greenland and Antarctica to regions most in need of fresh water; a computer simulation shows this solution to be viable and affordable

  • Water

    A revolutionary low-cost technique that uses sunshine to provide safe drinking water; solar disinfection (SODIS) of drinking water is an effective way of preventing water-borne diseases such as cholera, dysentery or polio — especially important in developing countries, where safe drinking water is often a precious rarity

  • Water

    Over one-third of the world’s population already lives in areas struggling to keep up with the demand for fresh water. By 2025, that number will nearly double; a new study argues that seawater desalination should play an important role in helping combat worldwide fresh water shortages once conservation, reuse, and other methods have been exhausted
