Flooded Pennsylvania Streamgage after Hurricane Isaias
This USGS streamgage on Schantz Spring near Wescosville, Pennsylvania was partially submerged after floodwaters from Tropical Storm Isaias quickly rose and flooded the area. USGS crews arrived on scene August 4 to

Fair weather cumulus at Chester County, PA Observation Well CH 10
Chester County, Pennsylvania Observation Well CH 10. The well is 33.5 feet deep, and lies in the local Cockeysville Marble Aquifer, part of the larger Piedmont and Blue Ridge carbonate-rock National Aquifer. The well is relatively new to the Groundwater Quality Monitoring Network (GWMN) consisting of 27 wells distributed over 26 counties in Pennsylvania. Wells are sampled

Kafrein reservoir captures runoff near the Dead Sea, Jordan
The Kafrein Dam captures runoff from Jordan River side valley wadis, near the Dead Sea, Jordan. USGS hosted a field trip that included a stop at the dam in February, 2017 during a regional workshop on aquifer storage & recovery in the Middle East and North Africa (MENA) region, in cooperation with the U.S. Agency for International Development.
Sampling a private well in Lycoming County, Pennsylvania
Brian Selck, a USGS National Association of Geoscience Teachers intern, collects a water level measurement from a domestic well at a site north of Jersey Shore in Lycoming County, Pennsylvania, June 2014.
Spring flow towards the Dead Sea, Jordan
Photo of low-flow conditions in a wadi (stream) along the Jordan Rift Valley. Springflow generated by groundwater discharge at higher elevations eventually flows into the hypersaline Dead Sea.
Well-withdrawal footprint map, Azraq Oasis, Jordan
Large groundwater withdrawals in the Azraq Oasis area, Jordan, have contributed to declining water levels in wells. This map shows the withdrawal footprint and observed water-level trends (labeled triangular symbols, from Goode et al. 2013). The footprint depth-rate index is 0.1 meter per year (m/yr), corresponding to a water-level decline rate of 1 m/yr, scaled by a
