U.S: Tracking the virus in wastewater is helping respond to the most recent wave of the coronavirus, but a more coordinated national effort is needed, experts sa

 

As the highly contagious Omicron variant pushes national coronavirus case numbers to record highs and sends hospitals across the country into crisis mode, public health officials are eagerly searching for an indication of how long this surge might last.

The clues are emerging from an unlikely source: sewage.

People who contract the coronavirus shed the virus in their stool, and the virus levels in local wastewater provide a strong, independent signal of how much is circulating in a given community.

The sewage data reveal an Omicron wave that is cresting at different times in different places.

Researchers Make Progress Toward High-Performing Water Desalination Membranes

http://www.sci-news.com/othersciences/materials/high-performing-water-desalination-membranes-09209.html

Biological membranes can achieve remarkably high permeabilities while maintaining ideal selectivities by relying on homogeneous internal structures in the form of membrane proteins. In new research, a team of scientists led by Penn State University and the University of Texas at Austin applied such design strategies to desalination polyamide membranes.

Dr. Enrique Gomez, Dr. Manish Kumar and their colleagues from Iowa State University, Penn State University, the University of Texas at Austin, DuPont Water Solutions, and Dow Chemical Co. found that creating a uniform membrane density down to the nanoscale of billionths of a meter is crucial for maximizing the performance of reverse-osmosis, water-filtration membranes.

HANOI, 7 August 2015 (IRIN) - Toxic sludge that spilled out of open pit coal mines during 10 days of heavy rains may have seriously contaminated farmland, rivers and coastal areas in northern Vietnam.

Flooding has killed 30 people, wiped out roads and damaged thousands of homes, the United Nations said in a situation report on Wednesday. The UN also warned of potential risks to the environment, health and water sanitation after coal mines in Quang Ninh province flooded, spilling thick streams of dark sludge into the countryside.

Are we reaching "Peak Water"?

ww_7_small2.jpg

WASHINGTON, D.C. Oct. 18, 2011 — According to Dr. Peter Gleick and his colleagues in the newest volume of the most important assessment of global water challenges and solutions, more and more regions of the world, including the United States, may be reaching the point of "peak water." To conserve this critical resource without harming the economy or public health, businesses, communities, governments, and individuals are looking for new techniques to move to sustainable water management.

The World's Water, Vol. 7 offers discussion and analysis for developing those reforms. For more than a decade, this biennial report has provided key data and expert insights into freshwater issues. In the seventh volume in the series, Gleick and his colleagues at the Pacific Institute address such issues as increased conflicts over water resources, "fracking" natural gas contamination, corporate risks and responsibilities around water, and the growing risks of climate change. They specifically explore:
