New Study Clarifies UV Degradation Pathways for PFAS, Correcting Misunderstood Chemical Mechanisms

A new study in Nature Water details how ultraviolet (UV) irradiation breaks down per- and polyfluoroalkyl substances (PFAS). Researchers found that hydrated electrons trigger a complex reaction involving hydroxyl radicals and hydroxide ions, leading to carbon-carbon bond cleavage. The study corrects previous misconceptions about chain-shortening and identifies formate as the primary product, offering new insights for treating PFAS pollution and designing degradable fluorochemicals.

Moringa seed extract cleans drinking water of 98% microplastics, beating traditional coagulants

A Brazilian study finds a salt-based extract from moringa seeds removes over 98% of PVC microplastics from drinking water, matching or outperforming aluminum sulfate (alum) and potentially simplifying treatment by enabling inline filtration. The moringa option offers greener benefits and lower sludge but raises questions about dissolved organic carbon leaching and requires scaling tests before widespread use.

Scientists Uncover Potentially Toxic Chemical in U.S. Tap Water

A newly identified chemical byproduct, chloronitramide anion, has been found in the drinking water of about a third of U.S. homes, raising concerns about its potential toxicity. This byproduct forms when water is treated with chloramine, a common disinfectant. Although its health effects are unknown, its similarity to other toxic chemicals warrants further investigation. The discovery highlights the ongoing challenge of balancing water disinfection with potential health risks from byproducts. Researchers emphasize the need for more studies to determine the chemical's safety.

"Health Risks of 2,6-DHNPs in Drinking Water: Research Findings"

A new study has highlighted the health risks posed by 2,6-DHNPs, a group of disinfection byproducts resistant to traditional water purification methods. These contaminants were found to be significantly more toxic than regulated DBPs, causing severe heart damage in zebrafish embryos. The study emphasizes the urgent need for advanced water purification technologies to effectively remove these pollutants and safeguard public health, as the contaminants surviving water treatment processes can lead to severe health outcomes in exposed organisms.

"Founder's Personal Tragedy Drives Breakthrough Technology to Eradicate PFAS"

Jacob Printz and his uncle, Steve Wilcenski, founded Invicta Water after Jacob's mother, Michelle, passed away from breast cancer believed to be caused by PFAS-contaminated drinking water. Invicta Water has developed a cost-effective and efficient system that uses boron nitride and UV light to destroy PFAS particles in water without toxic byproducts. The process is estimated to be 75% cheaper than current systems used by water treatment plants. Invicta is planning to pilot large-scale applications for water treatment and industrial use, as well as developing at-home versions of the system. The founders hope to prevent others from experiencing the heartbreak they faced with Michelle's death.

Water Concerns Prompt State of Emergency and Conservation Efforts in Hamilton and Jackson

The city of Hamilton in Alabama has resumed treating its water supply after a broken dam left it too muddy to treat for nearly two days. The city and surrounding communities had to conserve water, resulting in school and business closures. The source of the problem was a broken dam on private property north of Hamilton, which was located with the help of the Alabama Law Enforcement Agency's helicopter. Free water will be distributed to residents to help them cope with the intense heat, and the mayor expects things to return to normal by Sunday.

Solar Panels on Reservoir Power Water Treatment Plant in New Jersey

New Jersey American Water Company partnered with NJR Clean Energy Ventures to build the largest floating solar array in North America, consisting of 16,510 solar panels on the surface of the Canoe Brook Reservoir. The 17-acre solar array produces 8.9 megawatts of electricity, enough to power 1,400 homes, and provides 95% of the water treatment plant's energy requirements. Floating solar arrays are starting to catch on in the US, and a study published in March found that thousands of cities could generate an amount equal to all their electricity demand using floating solar.

Massive sewage spill contaminates Willamette River with 500K gallons

Massive sewage spill contaminates Willamette River with 500K gallons

A malfunction at a Lake Oswego water treatment facility caused 500,000 gallons of non-disinfected wastewater to flow into the Willamette River near Foothills Park. The public is advised to avoid the river in the area for two days due to the possibility of increased bacteria in the water. The wastewater had undergone most stages of treatment except for the final step of adding disinfectant, which failed and was repaired at 5:30 a.m. The City of Portland is working with Lake Oswego to replace the aging wastewater plant.
