Study: US Groundwater Supply Falls Short of Estimations

Understanding the findings with UA hydrologist and researcher Jennifer McIntosh.

While much of the focus is on Colorado River water, many communities in Southern Arizona rely on groundwater. A recent study found groundwater supplies nationwide fall short of previous estimates. Arizona 360 learned more from Jennifer McIntosh, a researcher in the study and hydrology professor at the University of Arizona. She explained findings show the availability of fresh groundwater resources is about half of what was estimated in earlier studies.

"We not only looked at that groundwater is being depleted from the top down, but we also investigated how groundwater is being depleted from the bottom up," McIntosh said.
