• California faces major decision on dams

    California already has upward of 1,000 dams that provide water supply, flood control, and hydropower, but California growing water shortages; last month Governor Arnold Schwarzenegger insisted he would not sign off on any major overhaul of the water system without money for new dams and reservoirs

  • Sandia researchers develop new water purification method

    Researchers substitute an atom of gallium for an aluminum atom in the center of an aluminum oxide cluster, creating a more effective process for removing bacterial, viral, and other organic and inorganic contaminants from river water destined for human consumption, and from wastewater treatment plants prior to returning water to the environment

  • Future of water in U.S. west threatened

    New study says there is a one-in-two chance of fully depleting all of the Colorado River reservoir storage system by mid-century assuming current management practices continue on course

  • Drinking water monitored by CSIRO-developed sensor network

    Lake Wivenhoe, which spans an area about the size of the city of Brisbane, supplies water to 1.5 million residents in south-east Queensland; CSIRO deploys its FLECK smart wireless sensor network technology to monitor water quality

  • Disinfectants create toxic by-products

    Using disinfectants to keep water drinkable was one of the major achievements of the twentieth century; a recent study now shows that the chemicals used to purify the water we drink and use in swimming pools react with organic material in the water yielding toxic consequences

  • Lab-on-a-chip detects pollutants, disease, and biological weapons

    Researchers develop nano-sized laboratory, complete with a microscopic workbench, to measure water quality in real time; breakthrough will help keep water safe from pollution and bioterrorist threats

  • Better detection with self-healing wireless sensor network

    New self-forming, self-healing wireless mesh sensor network can detect railway embankment landslides, humidity in art museums, water quality in water treatment facilities — and has military and security applications such as a perimeter network that can detect intrusion through breaking a light beam, or triggering a tripwire, or proximity sensor

  • ASCE assigns Grade of D to U.S. infrastructure

    Civil engineers association assigns a D grade to U.S. infrastructure, and says $2.2 trillion in repairs needed

  • Keeping water clean

    Researchers develop hydrogel material that can detect and remove contaminants in water; the hydrogel shrinks as it absorbs heavy metal pollutants, signaling the presence of cadmium and other toxic ions, even as it absorbs them from the contaminated water

  • The top 11 contaminants in U.S. drinking water

    U.S. citizens may upset to learn — should be upset to learn — that their drinking water contain disturbing amounts of pharmaceuticals and hormonally active chemicals; the concentrations are small, for now, but individuals with some health conditions should consult their physicians

  • New chemical radar among national security innovations in ACS podcast

    The American Chemical Society wants to do its share to bolster societal safety — and a new series of an the organization-sponsored podcasts describe an array of technologies to help assure personal safety and national security

  • New way to purify water

    Water-attracting materials seem to repel impurities, thus leaving a layer of pure water near their surface; making tubes from these particle-excluding materials would allow for a new way to purify water — if, for now, in relatively small quantities

  • Midwest floods to create record dead zone in Gulf of Mexico

    Each year, an influx of nutrients — mainly nitrogen — which come from fertilizers flushed out of the Mississippi basin creates dead zones in the Gulf of Mexico — zones where there is not enough oxygen to sustain life; the summer’s Midwest floods flush record levels of nutrients into the Gulf, creating a dead zone the size of New Jersey

  • Purifying farm-yard waste water

    Scottish researchers develop a method for turning farm-yard waster into water fit to bathe in; new method also prevents loss of contaminants to rivers and lakes, where they may be detrimental to animal or human health

  • U.S. intelligence agencies: Climate change threatens national security

    Climate change could threaten U.S. security in the next twenty years by causing political instability, mass movements of refugees, terrorism, or conflicts over water and other resources in specific countries
