A new peer-reviewed study from the Environmental Working Group finds that advanced PFAS filtration systems not only remove toxic "forever chemicals" from drinking water but also significantly reduce other harmful contaminants. These include cancer-linked disinfection byproducts, agricultural nitrates, and heavy metals like arsenic and uranium. The study, published in ACS ES&T Water, analyzed data from 19 U.S. utilities and the EPA’s national monitoring program, showing that technologies like granular activated carbon, ion exchange, and reverse osmosis offer broader public health benefits than previously recognized.

Confiscating personal belongings during government-led dismantling of tent cities in Vancouver inflicts immediate harm and further destabilizes people already struggling to meet their basic needs, according to a new study from Simon Fraser University.

Published in the journal Public Health, the study found nearly one in four people experiencing homelessness reported having their personal belongings confiscated by city workers between 2021 and 2023. These confiscations—often part of street sweeps to remove tent cities—were significantly associated with non-fatal overdoses, violent victimization, and barriers to accessing essential services.

A new IIASA-led study for the first time maps safe areas that can practically be used for underground carbon storage, and estimates that using them all would only cut warming by 0.7°C. The result is almost ten times lower than previous estimates of around 6°C, which considered the total global potential for geological storage, including in risky zones, where storing carbon could trigger earthquakes and contaminate drinking water supplies. The researchers say the study shows geological storage is a scarce, finite resource and warn countries must use it in a highly targeted way.
