How Much Arsenic is Too Little?
Five hundred utilities in the U.S. provide drinking water with unsafe levels of arsenic, the Environmental Protection Agency says. But how many people are getting too much arsenic in their water is much less clear, according to a study conducted in part by the Columbia Water Center.
AGU25, the premier Earth and space science conference, takes place December 15-19, 2025 in New Orleans, Louisiana. This year’s theme—Where Science Connects Us—puts in focus how science depends on connection, from the lab to the field to the ballot box. Once again, Lamont-Doherty Earth Observatory and Columbia Climate School scientists, experts, students, and educators are playing an active role, sharing our research and helping shape the future of our planet. #AGU25 Learn More
