• Changing rainfall patterns linked to water security in India

    Changing rainfall is the key factor driving changes in groundwater storage in India, according to a new study. The study shows that changing monsoon patterns—which are tied to higher temperatures in the Indian Ocean—are an even greater driver of change in groundwater storage than the pumping of groundwater for agriculture.

  • Groundwater resources around the world could be depleted by 2050s

    Human consumption could deplete groundwater in parts of India, southern Europe, and the United States in the coming decades, according to new research presented at the 2016 American Geophysical Union Fall Meeting. New modeling of the world’s groundwater levels finds aquifers — the soil or porous rocks that hold groundwater — in the Upper Ganges Basin area of India, southern Spain, and Italy could be depleted between 2040 and 2060.

  • How much water do we use? New interactive maps tells us

    Wash. Rinse. Repeat. With every shampoo or load of laundry you may wonder, how much water did I just use? Now multiply that thought across the nation and add other types of ways to use water, from irrigating crops to sustaining thermoelectric power generation. The USGS National Water-Use Science project has documented sixty years of water-use from 1950 to 2010 in an interactive map. You may choose a year and pick a category to see how much water your state uses.

  • Syrian crisis altered region’s land and water resources

    The Syrian civil war and subsequent refugee migration caused sudden changes in the area’s land use and freshwater resources. Using satellite imagery processed in Google Earth Engine, researchers determined the conflict in Syria caused agricultural irrigation and reservoir storage to decrease by nearly 50 percent compared to prewar conditions.

  • New wastewater system design guidelines help protect aquatic life

    New wastewater system design guidelines can help municipal governments better protect aquatic life and save millions of dollars a year. Engineers developed guidelines that can tailor the design of specialized filters, called fluidized bed reactors, to local conditions and help prevent phosphorous deposits from forming in wastewater systems.

  • New lead detector for water

    Engineers have developed what you might think of as a “canary in the coal mine” for lead in water. ). They designed a sensor with a graphene-based nanomaterial that can immediately detect lead and other heavy metals. The new platform technology can be used for one-time testing of lead in tap water through a handheld device.

  • Water resources for developing countries

    Water experts believe by 2050 almost half of the world’s population will live in countries with a chronic water shortage. The shortfall is the result of population growth, which leads to a greater demand for food, increased pollution, and climate instability. At the Ben-Gurion University of the Negev’s (BGU)’s Zuckerberg Institute for Water Research, eighty scientists and 250 graduate students are working on ways to tackle the problem using cutting-edge science in partnership with academics around the world.

  • People prefer conservation as way to protect drinking water

    The water crisis in Flint, Michigan put the need to protect and invest in clean drinking water front and center in the minds of many Americans. But how to go about investing, as well as how to get the public on board with such spending, is a difficult challenge that faces policymakers. Researchers have found that when given the choice, people prefer to invest their money in conservation, such as protecting key areas of a watershed — also referred to as green infrastructure — than traditional water treatment plants, also referred to as gray infrastructure.

  • Water war between Asian nuclear powers looms

    A potential global catastrophe looms in Asia as rapidly rising water demand collides with a diminishing resource on which at least 300 million people depend directly, and the current political rhetoric between India and Pakistan underlines the risk of failing to manage correctly and cooperatively vital water resources shared between nations. The Indus Water Treaty governs the distribution Himalayan-origin water in the 1,120,000 km2 basin drained by the Indus River, six major tributaries, and connected waterways among India, Pakistan, Afghanistan, and China, but India wants to modify the treaty or walk away from it – and Pakistan announced that any Indian attempt to renege from the Treaty would be deemed an act of war.

  • Mapping corrosive groundwater across the U.S.

    Approximately 44 million people in the United States rely on groundwater from wells as their water source. A new study found that untreated groundwater from twenty-five states could be potentially highly or very highly corrosive, a recent study finds. Corrosive water, while itself not dangerous, can dissolve lead and other metals from pipes, plumbing, and other metal surfaces into drinking water. While the quality of municipal water supplies is regulated and treated, domestic well owners are responsible for the treatment of their personal water supplies.

  • Assessing 100 years of Los Angeles groundwater replenishment

    A new study offers the most sophisticated analyses to date on how Los Angeles-area groundwater supplies are replenished. The analyses provide water managers with a clearer understanding of the sources and amount of available groundwater in the region — information that is important for planning and management of the vital resource.

  • Ambitious Baltimore water pollution clean-up project

    Baltimore’s Inner Harbor and the urban rivers that flow into it are important sources of water to Chesapeake Bay, popular recreation sites for residents and tourists, and the targets of an ambitious clean-up plan to make the harbor swimmable and fishable by the year 2020. In a first for Baltimore and the nation, the U.S. Geological Survey and the Environmental Protection Agency will soon be installing a suite of sensors that will provide the public and scientists with the first comprehensive, real time look at water quality in Baltimore’s Inner Harbor.

  • Even if the Paris Agreement is implemented, food and water supplies remain at risk

    If all pledges made in last December’s Paris climate agreement (COP21) to curb greenhouse gases are carried out to the end of the century, then risks still remain for staple crops in major “breadbasket” regions and water supplies upon which most of the world’s population depend. Recognizing that national commitments made in Paris to reduce greenhouse gas emissions fall far short of COP21’s overarching climate target — to limit the rise, since preindustrial times, in the Earth’s mean surface temperature to 2 degrees Celsius by 2100 — a new report advances a set of emissions scenarios that are consistent with achieving that goal.

  • New $4 million facility at UW to investigate natural disasters worldwide

    A new Post-Disaster, Rapid Response Research Facility at the University of Washington will provide necessary instrumentation and tools to collect and assess critical post-disaster data, with the goal of reducing physical damage and socio-economic losses from future events. The NSF’s $40 million NHERI investment, announced in September 2015, funds a network of shared research centers and resources at various universities across the nation. The goal is to reduce the vulnerability of buildings, tunnels, waterways, communication networks, energy systems, and social groups in order to increase the disaster resilience of communities across the United States.

  • Strengthening U.S. infrastructure to withstand disasters

    The delivery of essential services — whether in food, water, health, or emergency response — relies increasingly upon a complex, interconnected system of critical infrastructure. Ensuring these interdependent systems continue to operate during disasters and other disruptive events is crucial to maintaining public health and safety. NSF announces $22.7 million in new investments to promote better understanding and functioning of these infrastructures in an effort to improve their resilience.
