The potential effectiveness of harvesting rainwater to bolster water supply and reduce potentially polluting runoff varies greatly from place to place, even within a particular city or neighborhood. Now researchers at the Columbia Water Center have developed a tool to assess the potential of rainwater harvesting throughout the United States.
Columbia Water Center director Upmanu Lall suggests that we see the Oroville crisis as a call to action to evaluate and address the challenges facing the nation’s dam infrastructure.
Many schools are being tested for lead in their water. But what about the libraries, hospitals, offices and old apartment buildings? As I observe the new president and his EPA designee, I worry about the adverse effect deregulating environmental protection would have on our families. There is more work to do if we are to truly understand the impact of human technology on the environment and public health.

By Chandler Precht On December 9, 2016, students in the Undergraduate Program in Sustainable Development presented practical solutions to sustainability issues and challenges faced by real world clients. Under the guidance of Professor Stuart Gaffin and Professor Radley Horton, the Capstone Workshop offers students a chance to convey the knowledge and theories gained throughout their time in the… read more
Researchers at the Columbia Water Center have been analyzing trends in drinking water quality violations. A critical lesson is that water quality violations extend well beyond the problem of lead in Flint’s drinking water.
Across the nation, large-scale water infrastructure such as dams have provided a multitude of services, from electric power and water reservoirs to flood control and containment of pollution. But federal investments in large water infrastructure projects have largely been curtailed over the past few decades.
A team of scientists conducted an unprecedented health check of the entire Hudson River system, from its source to New York Harbor. This is what they found.
