Small amounts of oil leave a fluorescent sheen on polluted water. Oil sheen is hard to remove, even when the water is aerated with ozone or filtered through sand. Now, a University of Utah engineer has developed an inexpensive new method to remove oil sheen by repeatedly pressurizing and depressurizing ozone gas, creating microscopic bubbles [...]

The United States is using less water than during the peak years of 1975 and 1980, according to water use estimates for 2005. Despite a 30 percent population increase during the past 25 years, overall water use has remained fairly stable according to a new U.S. Geological Survey report.
Assistant Secretary of the Interior Anne Castle [...]

Researchers in MIT`s Department of Civil and Environmental Engineering believe they have pinpointed a pathway by which arsenic may be contaminating the drinking water in Bangladesh, a phenomenon that has puzzled scientists, world health agencies and the Bangladeshi government for nearly 30 years. The research suggests that human alteration to the landscape, the construction of [...]

Scientists are looking to outer space for help in their attempt to prevent new outbreaks of the tropical disease schistosomiasis in southern China.
Once the Three Gorges Dam is fully operational, researchers plan to use satellite data from space to determine whether changing water conditions in Poyang Lake, China’s largest freshwater lake, create [...]

A research group led by graduate student Violette Impellizzeri from the Max Planck Institute for Radio Astronomy has used the 100 m Effelsberg radio telescope to detect water at the greatest distance from Earth so far. The water vapour was discovered in the quasar MG J0414+0534 at redshift 2.64, which corresponds to a light travel [...]

Venus Express has made the first detection of an atmospheric loss process on Venus`s day-side. Last year, the spacecraft revealed that most of the lost atmosphere escapes from the night-side. Together, these discoveries bring planetary scientists closer to understanding what happened to the water on Venus, which is suspected to have once been as abundant [...]

Scientists in Oregon and Washington State are reporting the development and successful testing of a new method for determining the extent of illicit drug use in entire communities from water flushed down toilets that enters municipal wastewater treatment plants.
The technique may be an effective tool for comparing drug use in different regions of the United [...]

The best ways to improve energy security, mitigate global warming and reduce the number of deaths caused by air pollution are blowing in the wind and rippling in the water, not growing on prairies or glowing inside nuclear power plants, says Mark Z. Jacobson, a professor of civil and environmental engineering at Stanford.
And "clean coal," [...]

Agriculture producers may find they don`t have to bottle their water from the Seymour Aquifer in the Rolling Plains to make it more valuable, according to Texas AgriLife Research scientists.
Drs. John Sij, Cristine Morgan and Paul DeLaune have studied nitrate levels in irrigation water from the Seymour Aquifer for the past three years, and have [...]
