## NASA Study Finds Aquifer Depletion
NASA scientist Mary Michael O'Neill reports southwestern US aquifers are being depleted faster than they recharge.

> aquifers, rock layers holding water that serve as a key source of freshwater, are being "depleted faster than they recharge" in the southwest of the U.S.
## Study Uses Satellite Data
The study assessed global terrestrial water storage from April 2002 to November 2:0000 using NASA satellite data.

> The recent study assessed global terrestrial water storage (TWS) trends from April 2002 to November 2025 using satellite data from NASA
## Depletion Threatens Farming
Continued depletion threatens national food production capacity and rural economies in US agricultural regions.

> Continued depletion at these rates threatens the long-term viability of irrigated agriculture in these regions, along with the rural economies and food production that depend on them
## Local Impact on Farms
Groundwater depletion increases pumping costs and risks farm abandonment in Central Valley and High Plains.

> Falling water tables also raise pumping costs, which squeezes farm profitability and can accelerate consolidation or abandonment of smaller operations
## Water Storage Risks
Depletion causes land subsidence and reduces aquifer capacity in agricultural regions.

> In regions such as the Central Valley, continued groundwater depletion is also tied to land subsidence, which can damage canals, roads, and other infrastructure
## Expert Concerns
Experts warn groundwater depletion risks food security and economic stability in US farming regions.

> These findings are deeply concerning because groundwater supports both irrigated agriculture and drinking water supplies
## Local Solutions Needed
Better data and local monitoring are critical for managing groundwater use in farming regions.

> Better data won't solve the problem by itself, but it gives growers and water managers a better starting point
## Long-Term Risks
Persistent depletion reduces aquifer capacity and increases vulnerability to drought in US agricultural regions.

> The NASA scientist said that persistent depletion increases the country's vulnerability to drought, "since groundwater acts as a buffer during dry years"
## What Happens Next
US water managers need to implement local water budgets to address groundwater depletion.

> policymakers should combine that evidence with local well monitoring and enforceable, long-term water budgets
## Key takeaway

NASA study shows US southwestern aquifers are being depleted faster than they recharge, risking food production and rural economies.
