National Ground Water Association Highlights Groundwater’s Role in Meeting Data Center Growth

New article in Water Well Journal outlines potential challenges and opportunities with growth of data centers

(Westerville, Ohio-January 8, 2026) — As data centers continue to expand across the United States to support cloud computing, artificial intelligence, and digital infrastructure, the National Ground Water Association (NGWA) is underscoring the critical role groundwater professionals play in helping communities and companies manage water resources responsibly.

In a new cover story in Water Well Journal, the Association’s monthly trade magazine, NGWA experts examine how the rapid growth of data centers is increasing demand for both energy and water—often in regions already facing water constraints. On-site water use by data centers was estimated at approximately 17 billion gallons nationally in 2023, with usage expected to rise significantly in the coming years

“Data centers certainly pose some interesting water and energy challenges,” said William M. Alley, Ph.D., NGWA’s director of science and technology and one of the article’s authors. “But working together, I feel groundwater professionals can develop solutions to ensure our water resources are used responsibly and sustainably.”

The article highlights how groundwater professionals can support sustainable data center development through hydrogeologic evaluation, water-use planning, community engagement, and innovative cooling solutions—including geothermal systems and managed aquifer recharge. These approaches can significantly reduce or, in some cases, eliminate net groundwater consumption while supporting local water security.

To further advance responsible practices, NGWA has launched a Data Center Task Force of NGWA members focused on developing guidance for policymakers, utilities, communities, and data center developers. The task force will work to address groundwater availability, transparency in water use, and best practices for siting and operating data centers in ways that protect long-term water resources.

“As data centers move into more regions, particularly groundwater-reliant and rural communities, it’s essential that water resource professionals and communities are part of the conversation early,” said Alley. “NGWA is committed to bringing science, expertise, and practical solutions to the table, and promoting wider conversations about the development of ata centers.”

The Water Well Journal article is the first in a three-part series exploring data centers and groundwater, with additional installments scheduled for upcoming issues.

“Data centers are a hot-button topic right now and groundwater professionals can be at the center of ensuring they are built responsibly,” Water Well Journal Editor Thad Plumley said. “I am glad our publication is able to lead off this new year with such an important article series.”
