Big Data Offers Promise of Better Groundwater Management

To sustainably manage groundwater, water managers and regulators currently rely upon understanding the depths at which groundwater transitions from fresh (shallower) to more saline (deeper). This base of fresh water, while important, remains poorly understood. Here we show that, in California, 1) available base-of-fresh-water data do not represent actual base of fresh water, as exemplified by the widespread occurrence of fresh water deeper than the defined bases of fresh water, and 2) wells are already penetrating or encroaching on the defined bases of fresh water. We conclude that using current base-of-fresh-water data may limit efforts to manage deep groundwater effectively.
