• U.S. states agree on plan to manage overtaxed Colorado River

    Seven Southwestern U.S. states that depend on the overtaxed Colorado River have reached landmark agreements on how to manage the waterway amid an unprecedented drought, including a commitment by California to bear part of the burden before it is legally required to do so.

  • Climate change requires a fresh approach to water woes

    Climate change is affecting the Everglades and other large watersheds across the United States in new and unpredictable ways. Extreme weather events and rising sea levels, combined with a growing population, will lead to “more intense arguments” about already contested issues of water quality and water usage, experts say.

  • Early warning system for tracking groundwater contamination

    Groundwater contamination is increasingly recognized as a widespread environmental problem. The most important course of action often involves long-term monitoring. But what is the most cost-effective way to monitor when the contaminant plumes are large, complex, and long-term, or an unexpected event such as a storm could cause sudden changes in contaminant levels that may be missed by periodic sampling?

  • Urban water services vulnerable to attacks using a botnet of smart commercial irrigation systems

    Cybersecurity researchers warn of a potential distributed attack against urban water services which uses a botnet of smart irrigation systems. The researchers analyzed and found vulnerabilities in a number of commercial smart irrigation systems, which enable attackers to remotely turn watering systems on and off at will. Botnet attacks can also empty an urban water tower in an hour, and empty flood water reservoir overnight.

  • Groundwater recharge project helps California’s sustainability efforts

    The depletion of California’s aquifers by over-pumping of groundwater has led to growing interest in “managed aquifer recharge,” which replenishes depleted aquifers using available surface waters, such as high flows in rivers, runoff from winter storms, or recycled waste water. At the same time, there is growing concern about contamination of groundwater supplies with nitrate from fertilizers, septic tanks, and other sources. Study shows how collecting storm-water runoff to replenish depleted groundwater supplies can be coupled with a simple strategy to reduce nitrate contaminants.

  • Using satellites to measure vital underground water resources

    The availability of water from underground aquifers is vital to the basic needs of more than 1.5 billion people worldwide. In recent decades, however, the over-pumping of groundwater, combined with drought, has caused some aquifers to permanently lose their essential storage capacity. Scientists are using the latest space technology to measure this precious natural resource.

  • Water use across U.S. declines to levels not seen since 1970

    Water use across the country reached its lowest recorded level in 45 years. According to a new USGS report, 322 billion gallons of water per day (Bgal/d) were withdrawn for use in the United States during 2015. This represents a 9 percent reduction of water use from 2010 when about 354 Bgal/d were withdrawn and the lowest level since before 1970 (370 Bgal/d).

  • Next-generation water harvester delivers fresh water from air

    Last October, researchers headed down to the Arizona desert, plopped their newest prototype water harvester into the backyard of a tract home and started sucking water out of the air without any power other than sunlight. The successful field test of their larger, next-generation harvester proved what the team had predicted earlier in 2017: that the water harvester can extract drinkable water every day/night cycle at very low humidity and at low cost, making it ideal for people living in arid, water-starved areas of the world.

  • Will London run out of water?

    The U.K.’s Environment Agency warns in a new report that England could suffer major water shortages by 2030 and that London is particularly at risk. The BBC agrees, placing London on its recent list of 11 cities most likely to run out of drinking water along with the likes of Cape Town, where an ongoing water crisis has caused social and economic disruption. There are limits to what can be achieved just by fixing leaky pipes or getting people to water their lawns less often. Though such measures are useful, they will not safeguard London’s water supplies against the more extreme combinations of growth and climate change.

  • America’s water infrastructure is failing -- but we could start fixing it

    America’s water is under threat from many sides. It faces pollution problems, outdated infrastructure, rising costs, and unprecedented droughts and rainfall patterns as the climate changes. For decades, the U.S. has been a leader in water management. Now we’re falling behind; in the latest infrastructure report card, dams, drinking water and wastewater all received D ratings. Experts offer solutions.

  • As drought returns, experts say Texas cities aren't conserving enough water

    Three years after one of the worst droughts in Wichita Falls history, life is returning to normal. But as Texas creeps back into a drought, water experts say residents in the city and around the state can do more to conserve water and prepare for the next shortage, which is always on the horizon.

  • Gaza now has a toxic ‘biosphere of war’ that no one can escape

    The water of Gaza highlights a toxic situation that is spiraling out of control. A combination of repeated Israeli attacks and the sealing of its borders by Israel and Egypt, have left the territory unable to process its water or waste. Every drop of water swallowed in Gaza, like every toilet flushed or antibiotic imbibed, returns to the environment in a degraded state. The result is what has been termed a toxic ecology or “biosphere of war,” of which the noxious water cycle is just one part. People may evade bombs or sniper fire, but there is no escape from the biosphere.

  • New technology removes phosphorus from manure

    Excess phosphorus, primarily in runoff from land application of manure, accounts for about 66 percent of impaired conditions of U.S. rivers and has created large areas of eutrophication — dead zones — in the Chesapeake Bay and the Gulf of Mexico, where aquatic life cannot survive. Nutrient pollution is one of America’s most widespread, costly and challenging environmental problems. Researchers have developed an innovation that could have a huge impact on water quality problems in the United States, a system capable of removing almost all phosphorus from stored livestock manure.

  • Water crisis spurring protests in Iran

    A lack of water has been spurring protests in Iran against the regime since the beginning of the year, Reuters reported Thursday. The water crisis have taken place mostly in Isfahan, located in central Iran, and, the Khuzestan province in the west, which is largely inhabited by non-Persian Arabs who call the region Ahwaz.

  • In field tests, device harvests water from desert air

    It seems like getting something for nothing, but you really can get drinkable water right out of the driest of desert air. Even in the most arid places on Earth, there is some moisture in the air, and a practical way to extract that moisture could be a key to survival in such bone-dry locations. Now, researchers at MIT have proved that such an extraction system can work.
