Wastewater Detections Show Mpox Likely Underestimated
|
A new study based on wastewater samples collected in Poznan, Poland, last year shows considerably more mpox DNA than expected based on area cases and hospitalizations, suggesting the virus has been underestimated in central Europe. The study appears in the International Journal of Infectious Diseases.

New Water Treatment Technology Could Help Recycle Even Super Salty Waters
|
s climate change flames a megadrought in the U.S. Southwest, the country is hitting some worrisome records. The water level of Lake Mead, which provides water for millions of people, is hovering near its lowest ever. And in some places, the shrinking Colorado River, which irrigates about 5 million acres of farmland and quenches the thirst of over 40 million people, is just desert and dust.

New IWA Young Water Professionals Chapter in the USA
|
As part of IWA’s mission to empower Young Water Professionals to contribute to sustainable water management, a new IWA Young Water Professionals (IWA YWP) chapter was officially established in the USA in May 2023. This IWA YWP chapter will be the country’s go-to network boosting connections for YWPs and a platform to support equal opportunities and quality career development. As a voluntary network, the USA chapter is open to all water professionals aged 35 or below who are enthusiastic, dedicated, and passionate about water-related issues. Here, the YWP USA Chapter, presents some key points about the chapter.

When Water Shortage Impacts on the Desert: Story of the Middle East
|
Where before there was a great mass of water, today there is only dry soil and dust. Lake Urmia in north-east Iran was once the biggest lake in the Middle East and sixth largest saltwater lake on Earth. Now it has almost dried up completely, leaving behind just a salt plain. This is not an anomaly in the region. The top spots in the ranking of countries with the highest water scarcity in the world are occupied by Middle East nations – places where the annual use of water is much higher than the available supply.

Concern as Low Levels of Antidepressants and Antibiotics Found in Irish Rivers
|
A "concerning" new study has found Irish rivers contain low levels of antidepressants and antibiotics, with current wastewater treatment processes not sufficient to remove them. Between September 2020 and March 2022, researchers from Dublin City University (DCU) collected water samples from dozens of sites recommended by the Environmental Protection Agency (EPA) along the River Liffey, the River Suir, the River Nore, and the River Analee.

Immobilization of TiO2 Photocatalysts for Water Treatment in Geopolymer Based Coatings
|
Since its discovery by Fujishima and Honda 1972, the photocatalytic effect of titanium dioxide (TiO2) has generated considerable interest in various research fields with the aim of converting solar energy into chemical energy for various applications, such as degrading metallic or other inorganic pollutants, water disinfection, air purification and hydrogen generation [1,2,3,4]. Among semiconductors, TiO2 has demonstrated high activity while showing excellent physical and chemical properties such as biocompatibility, low cost, non-toxicity and photostability

Revolutionizing Photocatalysis: TiO2 Nanotube Arrays and Nanobubbles Take Center Stage!
|
Dye wastewater is a significant environmental challenge due to its high toxicity. Organic dyes have mutagenic, teratogenic, and carcinogenic properties that endanger human health while hindering plant photosynthesis, posing risks to the ecosystem. Traditional methods of treating organic pollutants have drawbacks such as low efficiency, high energy consumption, and incomplete treatment. Hence there is a need for new wastewater treatment methods.

Projects to Advance Zero-Waste Water Research, Solutions
|
A new master agreement with ENOWA, a company tasked with pioneering sustainable energy and water innovations, will support Penn State research efforts in sustainable water solutions. The agreement could see up to $6 million invested into developing much-needed zero-waste water solutions. The agreement offers funding for up to 15 projects, with five initial projects that will focus on desalinating water, recovering rare earth minerals and metals from water and brine, and minimizing water line strain and water loss.
