A study released by the Pacific Northwest National Laboratory explored groundwater extraction and how growing demand will affect remaining resources. Scientists focused on when and where groundwater levels could peak, meaning the water becomes so inaccessible that deeper wells or costly equipment are needed to meet demand.

As it becomes more difficult to access groundwater, international agriculture could be affected and the cost of food could rise.

The study illustrates that groundwater has finite characteristics, and water basins around the world – including some in the western United States – are reaching their limits. We learn more about the study from Hassan Niazi, an earth scientist with the national lab.
