Researchers at the University of Waterloo have developed a promising new device that uses solar energy to produce clean drinking water. This innovation tackles two crucial issues – water scarcity and dependence on fossil fuels for desalination. The device is remarkably efficient, converting 93% of sunlight into usable energy to produce roughly 20 liters of fresh water per square meter daily. This amount aligns with the World Health Organization's recommendation for basic human needs. The key component is a specially designed light absorber made from nickel foam coated with a conductive polymer and thermoresponsive pollen particles. This material effectively captures sunlight and converts it into heat to evaporate saltwater. The vapor then condenses on a cooler surface, leaving behind clean water. The researchers believe this technology has the potential to be particularly beneficial for coastal communities and island nations struggling with freshwater access. Its efficiency and reliance on renewable energy make it a sustainable solution for the global water crisis.

The EPA has set stricter limits on PFAS in drinking water, forcing water districts to take action. In Orange County, California, the Yorba Linda Water District built a large-scale PFAS treatment plant to clean up contaminated groundwater. The plant uses a resin filtration system to remove PFAS from water. Other cities in the area are also implementing similar solutions to address the widespread PFAS contamination in their water supplies.

Researchers at MIT developed a new water filtration system that removes harmful "forever chemicals" called PFAS. These chemicals are persistent and linked to health problems. The new filter uses natural silk and cellulose to remove PFAS and heavy metals from water. It's also antimicrobial, preventing filter clogging by bacteria and fungi. This innovation could be a more sustainable and effective solution to water contamination than current methods.

The study presents a framework to measure how water systems can adjust their energy use to help balance power grid supply and demand. Water systems, which use up to 5% of the nation's electricity, could offer similar benefits to batteries by adjusting their operations to align with real-time energy needs. The researchers developed a framework that assesses the value of energy flexibility in water systems from the perspectives of electric power grid operators and water system operators. They found that these systems could shift up to 30% of their energy use during peak demand times, leading to significant cost savings and easing pressure on the grid. The framework could help electricity grid operators evaluate energy flexibility resources across a range of water systems, compare them with other energy flexibility and energy storage options, and modify or price energy. The approach could also help water utility operators make more informed financial decisions about how they design and run their plants in an era of rapidly changing electricity grids. The study highlights how important energy pricing is for making the most of this flexibility.

A new method for destroying PFAS chemicals has been developed using a photocatalyst made of iron oxide and graphemic carbon. This method is more effective than previous approaches, as it can efficiently break down PFAS chemicals under sunlight. The researchers believe this method could be a valuable tool for cleaning up both municipal and industrial water systems contaminated with PFAS. By effectively destroying these harmful chemicals, this technology could contribute to a cleaner and healthier environment.

This is an article about a new discovery at MIT. It discusses the photomolecular effect, which is the ability of light to vaporize water without heat. The discovery could have many applications, such as improving climate models and desalination. The scientists were surprised by the discovery, and conducted many tests to confirm it. They believe that the photomolecular effect could explain “mysterious measurements” in the literature of clouds.

The European Commission plans to allow exemptions from a proposed ban on PFAS, or "forever chemicals," to protect key industries. Commission President Ursula von der Leyen said exemptions would be granted for uses necessary for the EU's digital and green transition and strategic autonomy. A full ban could put at risk investments in technologies such as semiconductors and batteries. The Commission aims to combat PFAS pollution while ensuring the investment security of key technologies. PFAS are used in thousands of products and machines, but they do not break down in the environment, raising concerns about long-term consequences. Certain PFAS can harm foetuses and cause cancer. Politicians and industries have raised concerns about the impact of a ban on green technologies.

The EPA is ramping up inspections of water facilities due to a rise in cyberattacks. They have found alarming vulnerabilities and are urging facilities to implement basic cybersecurity measures to comply with the Safe Drinking Water Act. Over 70% of inspected facilities are violating basic requirements. Recent cyberattacks have highlighted the ease of accessing sensitive equipment at water facilities. The EPA plans to use enforcement to address problems, but faces resource constraints. They offer free cybersecurity training and tools to water facility operators.

The article discusses the discovery of a massive freshwater aquifer off the US East Coast, known as the Continental Shelf Aquifer. This aquifer holds a vast amount of water, equivalent to two Lake Ontarios, and its origins have been a subject of scientific inquiry.
