The amount of water injected for conventional oil and gas production exceeds that from high-volume hydraulic fracturing and other unconventional oil and gas production by more than a factor of 10, according to a new report. Conventional methods of oil and gas production have been used since the late 1800s. An assessment of the environmental impacts of the petroleum industry should examine the conventional production methods, as well as fracking.
Researchers are paving the way toward greater safety for coastal residents and infrastructure by developing a better means of modeling the destructive force of tsunami waves.
Europe has the capacity to produce more than 100 times the amount of energy it currently produces through onshore windfarms, new analysis from the University of Sussex and Aarhus University has revealed.
Everywhere you go there are stormwater detention basins built near large construction projects intended to control the flow of rainwater and runoff. Now, those basins might help in controlling nitrogen runoff into rivers and lakes, according to Lauren E. McPhillips, assistant professor of civil and environmental engineering at Penn State.
An automatic chlorine dispenser installed at shared community water points reduces rates of diarrhea in children. The researchers hope the technique can improve uptake by providing good-tasting water and avoiding the need for behavior change.
While it holds promise, membrane distillation doesn't work perfectly. A key challenge is designing membranes to purify water efficiently while ensuring zero contamination of the clean water. In new experiments, CSU engineers offer fundamental insight into why certain membrane designs work better than others.
Inspired by the intricate system of water circulating in a tree, a team of researchers led by Princeton University, have figured out how to use a thin slice of wood as a membrane through which water vapor can evaporate, leaving behind salt or other contaminants. Most membranes that are used to distill fresh water from salty are made of polymers, which are derived from fossil fuels and are also difficult to recycle.
Special permeable concrete pavement can help reduce the 'urban heat island effect' that causes cities to sizzle in the summer, according to a Rutgers-led team of engineers.
As populations boom and chronic droughts persist, coastal cities like Carlsbad in Southern California have increasingly turned to ocean desalination to supplement a dwindling fresh water supply. Now scientists at the Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) investigating how to make desalination less expensive have hit on promising design rules for making so-called 'thermally responsive' ionic liquids to separate water from salt.
A new battery made from affordable and durable materials generates energy from places where salt and fresh waters mingle. The technology could make coastal wastewater treatment plants energy-independent and carbon neutral.
