Ancient Seawater Under Chesapeake Bay?|
November 14, 2013 | USGS
“USGS scientists have determined that high-salinity groundwater found more than 1,000 meters (0.6 mi.) deep under the Chesapeake Bay is actually remnant water from the Early Cretaceous North Atlantic Sea and is probably 100-145 million years old. This is the oldest sizeable body of seawater to be identified worldwide.” Quoted from the USGS press release.

Aquifers in Northern Kenya|
September 11, 2013 | UNESCO
“Two aquifers – the Lotikipi Basin Aquifer and the Lodwar Basin Aquifer – were identified using advanced satellite exploration technology. Their existence was then confirmed by drilling conducted recently by UNESCO, but there is need for further studies to adequately quantify the reserves and to assess the quality of the water.” Quoted from the UNESCO press release.
Vulnerability of Public-Supply Wells to Contamination|
September 4, 2013 | USGS
“Key factors have been identified that help determine the vulnerability of public-supply wells to contamination. A new USGS report describes these factors, providing insight into which contaminants in an aquifer might reach a well and when, how and at what concentration they might arrive.” Quoted from the USGS Newsroom.
