Researchers have recently published results identifying the major sources of E. coli breakouts on several beaches on Lake Michigan. They have also researched an effective method of reducing the breakouts and the resulting beach closings.
US consumers prefer the idea of using fresh water for any watering needs. In most cases, plants irrigated with recycled water saw no negative impact when compared to the same types of plants irrigated with pure, non-recycled water.
A new study of ancient mound builders who lived hundreds of years ago on the Mississippi River Delta near present-day New Orleans offers new insights into how Native peoples selected the landforms that supported their villages and earthen mounds -- and why these sites were later abandoned. (Includes link to video.)
For close to two weeks the combination of a nearly stationary front and tropical moisture caused almost continuous precipitation over much of the Mid-Atlantic. Using data from a constellation of satellites, NASA calculated the extreme rainfall that occurred in parts of the US.
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.
