  • Reduction in exposure to arsenic from drinking well-water in Bangladesh limited by insufficient testing and awareness

    This study considers potential policy responses to the still very high levels of exposure to arsenic (As) caused by drinking water from shallow tubewells in rural Bangladesh. It examines a survey of 4,109 households in 76 villages of Araihazar upazila conducted two years after a national testing campaign swept through the area. The area is adjacent to the region where a long-term study was ...

  • Case study - Discharge measurement deep within a cave

    Research is currently being conducted in the Hessenhau cave, located in southern Germany. The cave is the deepest known within the Swabian Alps at 144m (472 ft) and has a stream running through it that connects it to other caves within the area. Discharge measurements were taken in different parts of the cave with the OTT MF pro electromagnetic current meter. Reaching the bottom of the cave ...

  • Researchers date ancient water deep beneath earth’s surface

    When a pocket of ancient water was discovered deep beneath the Earth in 2013, a team of Canadian researchers estimated it to be roughly 1.5 billion years old. At the same site, they discovered a deeper pocket of water estimated to be at least 2 billion years old, making it the oldest water on the planet. Barbara Sherwood Lollar, a University of Toronto professor who led the team that discovered ...

  • Desalination plant in Egypt runs on wind & sun

    Fortis Wind Energy (NL) and Juwi Renewable (DE) install a 100kW hybrid system in Egypt. Egypt, the land of the pyramids, is known to us for its ancient culture and the last year because of the uprisings for more democracy. Egypt is less known for its large population (83 million) lives along the Nile (only 5.5% of the surface). The rest of the country is desert. The River Nile runs into Egypt ...

  • Inequitable allocation of deep community wells for reducing arsenic exposure in Bangladesh

    Community wells that extend deeper than most private wells are crucial for reducing exposure to groundwater arsenic (As) in rural Bangladesh. This study evaluates the impact on access to safe drinking water of 915 such intermediate (90–150 m) and deep (>150 m) wells across a 180 km2 area where a total of 48,790 tubewells were tested with field kits in 2012–13. Half the shallow private wells ...

  • Can trading pollution like stocks help fight climate change?

    The gas produced by hog manure at farms across the U.S. punches holes in the ozone layer, overheats the planet, and angers neighbors with its peculiar odor, a mix of rotten egg and ammonia. All that's needed to clear the air is to cover the manure with a system of tarps that captures the gas, but many farms don't do it because it's too expensive. "If you don't give people incentives to come up ...
