Water Resources

Like time and money, water in the West is often characterized by too much demand chasing too little supply. In response to such scarcity, water conservation seems the obvious, environmentally-friendly strategy to achieve the same outcome-a green lawn, food and fiber, or a hot shower-while using less water. Give water users the means to use less, and with any luck, they actually will. But such freedom can also inadvertently lead to more water use, whether that's via lush landscaping, more crops on marginal lands, or longer showers. How do we balance supply with demand to solve this problem?

The Department of Water Resources (DWR) won a prestigious national award March 5 for its influential role in the nation’s fight against climate change, receiving recognition for the Department’s outreach on climate resilience and for taking a comprehensive approach that aligns state and local water management.

In 2019, after years of advocacy by affected community members and environmental justice advocates, California passed new laws establishing the Safe and Affordable Drinking Water (SADW) Program. The program will strengthen the technical, managerial, and financial (TMF) capacity of water systems in communities and regions throughout the state, but without attention to the social and political dimensions it will likely fail to provide sustainable solutions.

Permitting of linear oil and gas pipeline projects involves complex processes undertaken by a range of parties that are each working to address specific regulatory goals and requirements. In recent years, the growth of the natural gas industry has expanded pipeline development into states unaccustomed to pipeline permitting and has increased the number of permits necessitating review by states and tribes. While this growth is a critical economic driver, it comes with challenges.

Through this Switzer Leadership Grant, Lauren Richter contributed as a key member of the Silent Spring Institute PFAS research team. PFAS are a class of extremely persistent synthetic chemicals common in nonstick, stain-resistant, and waterproof consumer products and widely found in drinking water of millions of Americans. Lauren led community workshops on PFAS at regional and national conferences, investigated the public costs of PFAS drinking water contamination on Cape Cod, and provided expert testimony at hearings on PFAS bills before state legislative committees in Rhode Island.

Melting Himalayan glaciers are releasing decades of accumulated pollutants into downstream ecosystems, according to a new study. The new research in AGU’s Journal of Geophysical Research: Atmospheres finds chemicals used in pesticides that have been accumulating in glaciers and ice sheets around the world since the 1940s are being released as Himalayan glaciers melt as a result of climate change.

Sometimes modern problems require ancient solutions. A 1,400-year-old Peruvian method of diverting water could supply up to 40,000 Olympic-size swimming pools' worth of water to Lima each year. That information comes from a new study published in Nature Sustainability. It's one example of how ancient methods could support existing modern ones in countries without enough water. ...
