Newly granular details may help cities plan strategies to deal with wastewater.

The university will routinely monitor sewage leaving student dormitories to head off outbreaks of COVID-19.

MPA in Environmental Science and Policy students travel to Israel to learn more about the geopolitical climate and resource management as a tool for peace.

A comprehensive plan outlines ways to clean up the Hudson River and reduce the impacts from development and climate change.

Kartik Chandran, an environmental engineer at Columbia, will discuss some of his urban wastewater treatment projects at a panel discussion Friday following the screening of a new film about Rio de Janeiro’s Guanabara Bay.

Innovations in the 2014 EPI include a new wastewater treatment indicator; a new approach to climate change indicators; and two new satellite-derived indicators for air quality and forests.

Can mushrooms help clean up oil spills? Can oysters filter sewage pollution? Industrial waste is being injected into the planet’s soil and water as a result of human activity. Pioneers in the field of conservation and sustainability are employing nature’s own biological task force to help clean up.

How can we overcome the main challenges we face in our urban wastewater systems today? Are there opportunities to improve sustainability in water treatment systems in US cities to support local food security?

Across the globe, 2 out of 10 people do not have access to safe drinking water, and in the U.S., many states face water shortages and droughts. As the global population continues to grow and climate change results in more water crises, where will we find enough water to meet our needs?

It’s a case of finding a use for what was thought of as waste. Sewage treatment processes produce methane and nitrous oxide, both greenhouse gasses, while leaving undesirably high levels of nitrogen in the discharged water. On their own, all three of these things are harmful to the environment. Stanford University reports that a team has found a way to take those unwanted waste gasses and use them to 1) reduce the amount of nitrogen in the water, 2) produce an alternative energy source and 3) dispose of the nitrous oxide cleanly – by using it as rocket fuel, in fact.
