As the seven Colorado River Basin states haggle over the future of water allocations, authors of a new report on groundwater argue that equal attention should be paid to the water beneath our feet.

Jay Famiglietti, a global futurist professor at Arizona State University and one of the authors of the research, said groundwater depletion has been worse than losses measured at reservoirs like Lake Mead or Lake Powell. 

"I think Ted Cooke is a great choice for this job for a couple of reasons. One, as you mentioned, is that he's really familiar with the issues related to the Colorado River, and we're at a critical time. But in addition to that, Ted was the general manager of the Central Arizona Project and so he's very familiar with  the ground practicalities that all of the stakeholders in the Colorado River discussion live with, so he's a very good choice at this moment as commissioner," said Sarah Porter, director of the Kyl Center for Water Policy at Arizona State University,

“I’ve heard on calls that about 25% of the workforce is now gone from Reclamation in general, and so just for water in the West, that’s significant.”

“These settlements will continue to go through, but I don’t think the motivation for conservation will be as significant as previous administrations,” stated ASU's Cora Tso, suggesting there’s “more of an emphasis” on the Navajo-Hopi-San Juan Southern Paiute deal as opposed to the Yavapai-Apache Nation’s $1 billion bill involving the Verde River.

“This idea of water investments looks different from administration to administration, but it’s just what industries,” she explained. “The Trump administration is prioritizing oil and gas and nuclear energy in the West, so it doesn’t seem like those water concerns are an issue for them.”

“I think that it is not necessarily as clear to everyday Americans, about the connection between the development of AI and the physical infrastructure behind the technology and the subsequent energy, water and land use,” said Dave White, the director of the Global Institute of Sustainability and Innovation at ASU.

Tech innovation over the last decade has expanded the ways environmentalists can explore sustainability and conservation strategies, White said. But the decision to use newer tech tools, like AI models, which require physical infrastructure and large amounts of energy, water and other resources, isn’t a straightforward one for those interested in conservation. 

For Jay Famiglietti, a study co-author who pioneered the practice of using satellites to study groundwater at ASU, the loss of 27.8 million acre-feet of groundwater should be a wake-up call for everyone from decision-makers to regular citizens who call the West home.

“Groundwater is a trans-generational resource,” Famiglietti said. “If we want our great-great-great-grandchildren to eat, then it’s time to think more holistically about the water that we use and what kind of protection it needs.”

A recent study finds the Colorado River Basin has lost a tremendous amount of water in the last two decades, in part from thirsty farms pumping water from deep aquifers much faster than it can be replenished. Lead author Jay Famiglietti, a Global Futures Professor at Arizona State University, spoke with Living on Earth’s Paloma Beltran about the “Wild West” of unregulated groundwater, potential solutions and why the rapid depletion of ancient groundwater threatens the water supply for future generations.

Recharging is more or less what it sounds like: “Reclaimed water soaks into the aquifer, it mills around down there, and you get a credit,” Kathryn Sorensen, director of research for the Kyl Center for Water Policy and former director of Phoenix Water Services, explained. “That credit becomes a right to pump a well.”
