A new CU-Boulder study warns that climate change could lead to a one-in-two chance of fully depleting the Colorado River's reservoir storage by mid-century. The study found that even with a 20% reduction in stream flow, the risk of full depletion would still be significant.
Climate change may lead to a significant impact on water supplies, with changes in groundwater recharge potentially exceeding those in precipitation. The research focused on a semi-arid region near Lubbock, Texas, finding that timing and duration of rainfall events play a crucial role in determining the effects.
Forests provide natural filtration and storage systems that process nearly two-thirds of the U.S. water supply. Preserving and managing forests may help sustain water supplies, but forest management is unlikely to increase water yields.
Waters Corporation is offering complimentary drinking water analysis to US water authorities to assess regional exposure and develop solutions for pharmaceutical residues. The program aims to provide a baseline understanding of exposure levels to facilitate long-term monitoring and action plans.
A study published in PLOS Neglected Tropical Diseases found that Nigerian children attending government-owned schools have a higher prevalence of intestinal worms than those attending private schools. The water supply and sanitation conditions were also poorer in the government schools.
A versatile algorithm called Cascades, developed by Carnegie Mellon researchers, identifies the best 100 blogs to read for early access to news. The algorithm also helps design efficient sensor networks in water supply systems by balancing cost and information collection.
Researchers at the University of Manchester discovered that nails are most resilient in humid environments with a relative humidity of 55-60%. This finding may help improve false nail and varnish products, reducing breakage and damage.
Researchers found that over 40% of the marshes have been reflooded and native species are recovering, with growth in giant reeds and rare bird sightings reported. However, challenges remain, including water supply issues and potential environmental threats from oil exploration.
A recent study found that factors such as development, population growth, and failing water supply systems contribute significantly to water emergencies in Rockland County, N.Y. The researchers' findings suggest that the balance between water demand and supply is becoming increasingly fragile due to human activities.
A team of researchers found that the 2004 tsunami contaminated coastal drinking water sources in Sri Lanka by pouring seawater into open dug wells. The study also showed that efforts to restore wells were sometimes counterproductive, causing more contamination.
A Scripps-led study finds that climate warming will shrink key water supplies around the world, affecting millions. Glacier-dependent regions like China, India, and parts of South America are particularly vulnerable to vanishing glaciers, which will lead to costly disruptions in water supply and resource management systems.
A study suggests that breathing in manganese vapor during a shower can cause permanent brain damage, posing a significant risk to public health. The researchers found that concentrations as low as 0.5 milligrams per liter may lead to brain injury, despite the Environmental Protection Agency's current drinking water standard.
Forecasts project Illinois water use to grow faster than population, with increased demand for energy production. The Midwest region will need almost 17 billion gallons of water per day by 2025, mostly for electricity generation.
Researchers at the University of Illinois have developed a polymer-based colloidal adsorbent that effectively removes troublesome natural organic matter from municipal water supplies. The technology reduces the formation of harmful chlorinated compounds, ensuring safer drinking water without creating dangerous byproducts.
A new study by William Checkley and colleagues found that water and sanitation are key determinants of infant health in developing countries. The research, conducted on 230 Peruvian infants, revealed that inadequate water and sanitation can lead to higher rates of diarrheal episodes and stunted growth.
A recent study by the USGS found that 20% of homes in Hillsborough, Rockingham, and Strafford counties have arsenic concentrations above 10 micrograms per liter. In some areas, the incidence is as high as 30%. The study highlights the importance of testing private wells for arsenic to protect public health.
A USGS study reveals elevated arsenic concentrations in private wells are prevalent and pose a health threat to the public. The study focused on eastern New England, where high-growth suburban areas rely heavily on private wells, leading to increased risks.
The Romans developed various pragmatic solutions to water problems, such as using wells in Ostia and small elevations in Pompeii to guide rainwater. However, their sewage systems were often simple and not as advanced as modern standards.
University of Houston researchers are studying novel filtration membranes that can remove up to 90% of natural organic material from water. Their goal is to design better large-scale filtration systems to improve the quality of drinking water supplies, particularly in areas with contaminated or dirty water sources.
Researchers found that groundwater in aquifers is generally older than expected based on flow velocity, due to mixing between aquitards and aquifers. This discovery has significant implications for estimating water supply yields and predicting contaminant migration rates.
