New paper with the crew at the Occoquan Lab and a big team of collaborators. We built a modeling framework that helps explain how deicing salts move through urban watersheds and shape stream salinity and drinking water quality. www.sciencedirect.com/science/arti...
most deicer‑derived chloride travels through subsurface pathways, and stream water age emerged as a powerful lens for understanding salinity patterns across seasons and storm events.

WHO comments on United States announcement of intent to withdraw

The World Health Organization regrets the announcement that the United States of America intends to withdraw from the Organization.
WHO plays a crucial role in protecting the health and security of the world’s people, including Americans, by addressing the root causes of disease, building stronger health systems, and detecting, preventing and responding to health emergencies, including disease outbreaks, often in dangerous places where others cannot go.

The United States was a founding member of WHO in 1948 and has participated in shaping and governing WHO’s work ever since, alongside 193 other Member States, including through its active participation in the World Health Assembly and Executive Board. For over seven decades, WHO and the USA have saved countless lives and protected Americans and all people from health threats. Together, we ended smallpox, and together we have brought polio to the brink of eradication. American institutions have contributed to and benefited from membership in WHO.

With the participation of the United States and other Member States, WHO has over the past 7 years implemented the largest set of reforms in its history, to transform our accountability, cost-effectiveness, and impact in countries. This work continues.

We hope the United States will reconsider and we look forward to engaging in constructive dialogue to maintain the partnership between the USA and WHO, for the benefit of the health and well-being of millions of people around the globe.
