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 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.

USGS scientists prepare water-quality instruments before going out on the Great Salt Lake. USGS scientists are conducting a study to gain a better understanding of nutrient levels, which could help determine how to best manage algal bloom outbreaks.
