    The final 100 miles of the Colorado River is a shell of its former self — nearly 10 miles wide at the turn of the century, farmers had more water than they knew what to do with. Now, a weave of concrete canals brings water to sprawling industrial farms situated in the Mexicali Valley, with much of the natural riverbed dry and the wildlife sparse. Where did all the water go?

  • WATER SECURITY

    There are three main forces driving the conflict on the Colorado River. The first is an outdated legal system that guarantees more water to seven Western states than is actually available in the river during most years. The second is the exclusion of Native American tribes from this legal system. The third is climate change, which is heating up the western United States and diminishing the winter snowfall and rainwater that feed the river. Landmark agreements would cut big states’ water usage for decades and deliver water to the Navajo Nation.

    The Colorado River District plans to buy the water rights that flow through Colorado’s Shoshone hydropower plant. The acquisition is seen as pivotal for a wide swath of the state, and has been co-signed by farmers, environmental groups, and local governments.

  • CRITICAL MINERALS

    Critical minerals for the clean energy transition are abundant in the Southwest, but the dozens of mines proposed to access them will require vast sums of water, something in short supply in the desert.

    Groundwater is rapidly declining across the globe, often at accelerating rates. Researchers raise the alarm over declining water resources, but offer instructive examples of where things are going well, and how groundwater depletion can be solved.

  • WATER SECURITY

    The world’s groundwater aquifers are taking a beating. Decades of unrestrained pumping by thirsty farms and fast-growing cities have drained these underground rock beds, which hold more than 95 percent of the planet’s drinkable water. New research shows how to protect the aquifers that hold most of the world’s fresh water.

    Researchers achieved a major breakthrough in Redox Flow Desalination (RFD), an emerging electrochemical technique that can turn seawater into potable drinking water and also store affordable renewable energy.

    Houston’s water and wastewater system could be more resilient with the development of hybrid urban water supply systems that combine conventional, centralized water sources with reclaimed wastewater. Reclaimed wastewater could make supply systems more resilient.

    Restored floodplains in the state’s agricultural heartland are fighting both flooding and drought. But their fate rests with California’s powerful farmers.

    Engineers have refined a model that not only cultivates green energy, but also desalinates ocean water for large, drought-stricken coastal populations.By pumping seawater to a mountaintop reservoir and then employing gravity to send the salty water down to a co-located hydropower plant and a reverse osmosis desalination facility, science can satisfy the energy and hydration needs of coastal cities with one system.

    Twenty families in the Imperial Valley received a whopping 386.5 billion gallons of the river’s water last year — more than three Western states. Century-old water rights guarantee that supply.

  • WATER SECURITY

    Global water resources are stretched by climate change and human population growth, and farms and cities are increasingly turning to groundwater to fill their needs. Unfortunately, the pumping of groundwater can cause the ground surface above to sink. A new study maps, for the first time, the permanent loss of aquifer storage capacity occurring globally.

    Working closely with local conservation group, researchers develop new model to predict climate-change driven saltwater intrusion that is transferable to other vulnerable coastal communities.

    A looming depletion of groundwater across the U.S. has drawn nationwide attention in recent years, as local officials in states from Kansas to Arizona struggle to manage dwindling water resources even as homes and farms get thirstier. With little fanfare, the administration is using infrastructure funding to revive dormant plans for pipelines and reservoirs in rural areas across the U.S. West.

    Following growing concerns about the cybersecurity of the U.S. water infrastructure, the EPA announced this week it will no longer require cybersecurity audits of water utility facilities through sanitary surveys.

    Political leaders in the Mississippi River area are looking to form a multistate compact to manage threats from climate change, water pollution and drought-affected regions elsewhere. Twenty million people drink from the Mississippi River and its tributaries every day, and the river has led to more than 350,000 jobs and generates more than $21 billion in annual tourism, fishing and recreation spending.

    The Grand Ethiopian Renaissance Dam conflict has lasted for more than a decade without a resolution. Some experts warn that any further delays in settling the outstanding issues could have dire consequences.

    Increased demand for water due to global population growth, coupled with the increasing frequency of extreme weather events, endangers our water security. Nonetheless, little is known about the relationship of water use by sectors and the occurrence of drought-heatwave events, particularly at the large scale.
