Groundwater provides drinking water for millions of Americans and is the primary source of water to irrigate cropland in many of the nations most productive agricultural settings. Although the benefits of groundwater development are many, groundwater pumping can reduce the flow of water in connected streams and rivers -- a process called streamflow depletion by wells. The USGS has released a new ... read more >>
Texas endured its driest year ever in 2011, and southern Alabama and Georgia have continued to suffer serious drought in 2012. Climate change is predicted to make drought more frequent in the southern United States, putting a strain on groundwater resources. This visualization reveals the freshwater stores that NASA's GRACE (Gravity Recovery and Climate Experiment) satellite detects from space an ... read more >>
Massive extraction of groundwater helped unleash an earthquake in southeastern Spain last year that killed nine people, injured at least 100 and left thousands homeless, geologists said on Sunday.
The finding adds a powerful piece of evidence to theories that some earthquakes are human-induced, they said.
Seismologists were surprised by the May 11, 2011 earthquake which happened two kilometres ... read more >>
The deserts of Utah and Nevada have not always been dry. Between 14,000 and 20,000 years ago, when large ice caps covered Canada during the last glacial cooling, valleys throughout the desert southwest filled with water to become large lakes, scientists have long surmised. At their maximum size, the desert lakes covered about a quarter of both Nevada and Utah. Now a team led by a Texas A&M Univer ... read more >>
