A study of drinking water in Appalachian Ohio found no evidence of natural gas contamination from recent oil and gas drilling. Geologists with the University of Cincinnati examined drinking water in northeast Ohio where many residents rely on water from private underground wells. The time-series study was the first of its kind in Ohio.
NASA Satellites Reveal Major Shifts in Global Freshwater (NASA Headquarters). In a first-of-its-kind study, scientists have combined an array of NASA satellite observations of Earth with data on human activities to map locations where freshwater is changing around the globe and to determine why.
A new global, satellite-based study of Earth's freshwater found that Earth's wet areas are getting wetter, while dry areas are getting drier. The data suggest this pattern is due to many factors, including human water management practices, human-caused climate change and natural climate cycles. The NASA-led research team used 14 years of observations from the Gravity Recovery and Climate Experiment (GRACE) mission to track global trends in freshwater in 34 regions around the world.
In Texas, the Southern High Plains uses water from an aquifer to water cotton fields. However, the aquifer is running low. Scientists from the area are working to find the best irrigation method for cotton that uses the least water.
At a time when countries are pledging to restore millions of hectares of forest, new research argues that recent studies on forest regeneration techniques are flawed. Sites used to evaluate natural regeneration were secondary growth forests, whereas sites chosen to evaluate artificial regeneration ranged from abandoned coal mines to cattle-trampled fields. Authors of the new study suggest elements of both techniques should be considered, depending on the objectives for a site and its current state.
Ecologists have long known that agricultural and sewage pollution can cause low oxygen conditions and fish kills in rivers. A study published today in Nature Communications reports that hippo waste can have a similar effect in Africa's Mara River, which passes through the world renowned Maasai Mara National Reserve of Kenya, home to more than 4,000 hippos.
Scientists from the University of Leeds have developed a new global index that identifies water supplied from peatlands as a significant source of drinking water for the UK and the Republic of Ireland.
Research has shed new light how an increasingly common consumer product component -- silver nanoparticles -- can potentially interfere with the treatment of wastewater.
Sustainable, biological filters called slow sand filters have been used to filter drinking water since the 1800s. They don't use any chemicals, create no waste and use very little energy. New research from Lund University in Sweden shows that not only are the older filters more efficient cleaners -- they could be making a comeback soon with the help of new technology.
Majorities of Americans say the federal government is doing too little to protect key aspects of the environment, according to a new study released today by Pew Research Center. In a national survey of 2,541 US adults, 69 percent of Americans say the federal government isn't doing enough to protect water quality of lakes, rivers and streams and 64 percent say the same about air quality. Two-thirds (67 percent) say the government is doing too little to reduce the effects of climate change.
