USGS scientist Nick Voichick rafted about 150 miles in nine days on the Grand Canyon portion of the Colorado River to collect groundwater samples from springs in remote locations. 

 

USGS scientist Joel Unema hikes to National Canyon Spring to collect groundwater samples from a remote location near the south rim of the Grand Canyon. Joel Unema was part of a group of USGS and National Park Service scientists that rafted 150 miles in nine days to better understand natural resources.

USGS scientists Tom Porter and Joel Unema warm up in the sun as the scientific expedition moves downstream to the next sample location.

USGS scientists Kim Besiner, John Solder and Kate Wilkins collect groundwater samples at Grapevine Main Spring. 

Scientists traveled to the remote locations along the south rim of the Grand Canyon to assess the potential effects of mining along the Coconino Plateau and groundwater withdrawals associated with increasing populations.
