A new study by Colorado State University reveals that ag irrigation prevents higher greenhouse gas emissions by avoiding land conversion, saving 363 years' worth of emissions. Irrigation allows the US to grow more food on less land, reducing land-use change and its associated emissions.
Researchers developed a cost-effective and sustainable approach to produce freshwater by capturing water vapor from the air using specialized materials. The wind-driven strategy utilizes hygroscopic polymer sponges integrated with wind-powered eddy current heating, generating up to 9.9 liters of water per day.
Satellite remote sensing allows researchers to monitor water quality by tracking changes in light spectrum, identifying nutrients in the water. This technology holds promise for studying global river health and detecting toxic algal blooms that can shut down water treatment plants.
New research shows that antibiotics can drive bacterial resistance even after they are broken down in wastewater treatment plants and discharged into rivers and seas. The study found that some metabolites form when antibiotics break down retain the ability to promote antibiotic resistance.
Researchers developed a dynamic optimization model to help NGOs in rural Africa optimize maintenance schedules, reducing downtime and logistics costs. The model achieved significant reductions in maintenance downtime, ranging from 47-62% in Ethiopia and 53% in Malawi.
Researchers warn that wildfires can contaminate drinking water distribution systems, posing substantial public health risks. Over 50 volatile organic compounds have been detected in water distribution systems after wildfires, including carcinogens such as benzene.
A team of scientists from Rutgers University found that water did not arrive as early in Earth's formation as previously believed. Instead, the data suggest that water was delivered to the planet in smaller portions after the Moon's formation, far later during late accretion.
A survey conducted by Professor Takahiro Endo at Osaka Metropolitan University found that Hiroshima Prefecture provided a free water inspection service for well owners after the 2018 floods, promoting their initiative to open inspected wells to the public. This collaborative effort supplemented local governments' emergency water supply...
A new study warns that Colorado's West Slope basins, supporting a $5 billion agriculture economy, face a potential tipping point due to drought vulnerability. The research suggests that even moderate climate change and streamflow declines can threaten water storage, agriculture, and municipal supplies.
The University of California report highlights the need for more efficient water use in California agriculture as water availability declines due to climate change. The report suggests capturing runoff and groundwater to store water for a more resilient agricultural sector.
The two-year program will help recruit, teach, and graduate the next generation of water pipeline managers. The GLWA faces significant employee recruitment, training, and retention challenges due to technological advances in the water sector.
A new study proposes cost-effective informal water contracts as a solution to quickly and affordably bring water to cities during droughts. Informal water leases enable rapid transfers by bypassing complex regulatory processes.
A new study from Colorado State University suggests that transitioning to green wastewater-treatment approaches, financed through carbon markets, could save $15.6 billion and reduce CO2-equivalent emissions by 30 million tonnes over 40 years. The research explores the potential economic tradeoffs of switching to green infrastructure an...
Rice University engineers have developed a hybrid urban water supply system that combines conventional, centralized water sources with reclaimed wastewater to save energy and reduce freshwater use. The system is also more resilient against disruptions such as hurricanes and flooding.
A new computer model quantifies the black market for drinking water in Jordan, revealing that 91% of traded water is extracted illegally. The study predicts a significant increase in household dependence on private water suppliers due to decreasing public water supply infrastructure.
Researchers found tiny salt crystals in an asteroid sample, indicating the presence of liquid water. The discovery challenges previous assumptions that ordinary chondrite asteroids lack hydrated minerals.
Researchers developed algorithms to analyze acoustic signals from fire hydrant-mounted hydrophones, pinpointing leaks in aging water distribution networks. This technology supports water conservation efforts, especially in the Western US where leaks are a significant issue.
A new study from Harvard T.H. Chan School of Public Health estimates that regulations reducing lead and copper contamination in drinking water generate $9.2 billion in health benefits annually, exceeding the EPA's public estimates by an order of magnitude. The analysis also reveals at least $2 billion in infrastructure benefits, bringi...
A new study led by University of Maryland researchers found that melted meteorites have extremely low water content, ruling them out as the primary source of Earth's water. The team suggests that unmelted, or chondritic, meteorites may be responsible for delivering water to our planet.
A recent study from the University of Copenhagen reveals that Mars was once covered in a 300-metre-deep ocean, filled with water and icy asteroids carrying biologically important molecules. This finding suggests that conditions allowing the emergence of life were present on Mars long before Earth.
A new study warns that California's water resilience planning may not be financially viable without careful partnership agreements, as benefits may not be evenly distributed among stakeholders. The research highlights the importance of considering multiple factors to construct investment partnerships that satisfy all partners.
The University of Kansas team is creating new models to forecast water availability in Kansas, accounting for climate uncertainty. The project will improve tools for the Kansas Water Office to incorporate climate variability into future water supply planning.
A new analysis found US states with water shutoff moratoria had significantly lower daily COVID-19 infection and death rates. Comprehensive moratoriums resulted in even greater reductions, suggesting universal access to water can help prevent public health crises.
Researchers found that interplanetary dust particles carry both water and organics needed for the origin of life. This mechanism could also work for exoplanets, enabling water formation through solar wind irradiation. The discovery sheds light on the Moon's OH and water ice, as well as asteroid and comet origins.
Researchers at Scripps Institution of Oceanography found that human-caused climate change will reduce the Colorado River's capacity to deliver water, leading to shortfalls 40-90% of the time by 2025 and doubling by the late century. The study suggests that reducing average water use could help sustain the system.
