Opponents of hydraulic fracturing often comment on its high water use. Yet a comprehensive total of just how much water used during the process of hydraulic fracturing has been hard to come by.
A new U.S. Geological Survey study tallied up the amount of water used in hydraulic fracturing -- the process where water is injected underground, along with a mix of sand and chemicals, to fracture rock and release hydrocarbons. The analysis found that certain types of wells, in specific production basins, used a lot more water than others.
Scientists with the University of Colorado Boulder and the U.S. Geological Survey are calling for changes in monitoring and addressing human-caused earthquakes.
Over the past 13 years, many parts of the United States that are not earthquake prone have begun experiencing significant quake activity. In Colorado and other states east of the Rocky Mountains, the earthquakes are linked to injection of wastewater from oil and gas production.
The paper, published Feb. 19 in the journal Science, calls for better monitoring of these earthquakes and injection wells linked to such quakes. The ultimate goal is to use such monitoring to change the wastewater injection activities that cause the quakes, reducing risk to humans and property.
White-Nose Syndrome, a disease famous for killing millions of bats in the Eastern United States, has not yet made its way to Colorado – something wildlife managers are happy about. It's still an issue of concern, though, and at the U.S. Geological Survey's Fort Collins Science Center, a researcher has helped make a breakthrough in scientists' understanding of the deadly fungus.

The bat disease known as white-nose syndrome has been spreading fast, killing millions of animals. But for the first time, scientists are seeing hopeful signs that some bat colonies are recovering and new breakthroughs could help researchers develop better strategies for helping bats survive.
