RESTON, Virginia, May 23, 2013 (ENS) – Aquifers across the United States are being drawn down at an increasing pace, finds a new study released today by the U.S. Geological Survey.
The report, “Groundwater Depletion in the United States (1900-2008),” evaluates long-term cumulative depletion volumes in 40 separate aquifers in the United States, bringing together information from
previous studies and from new analyses of these distinct underground water storage areas.
“Although groundwater depletion is rarely assessed and poorly documented, it is becoming recognized as an increasingly serious globalproblem that threatens sustainability of water supplies,” writes report
author USGS hydrologist Leonard Konikow.
Since 1950, the use of U.S. groundwater resources for agricultural, industrial, and municipal purposes has expanded. When groundwater is
withdrawn from subsurface storage faster than it is recharged by
precipitation or other water sources, the result is groundwater
depletion.
