USGS Scientists Collecting a Water Sample from a Well at the USGS Bemidji Research Site
USGS Scientists Collecting a Water Sample from a Well at the USGS Bemidji Research SiteU.S. Geological Survey (USGS) scientists collecting a groundwater sample from a well at the USGS Bemidji Crude-Oil Spill Research Site, Minnesota. The scientists monitored in real time the dissolved oxygen, pH, specific conductance, and temperature of the water as the well is pumped so they can know when to collect representative sample.

Cement-lined channels slowly being removed for stream rehabilitation
Cement-lined channels slowly being removed for stream rehabilitationCement-lined channels such as this one in a section of the Kinnickinnic River at 11th Street in Milwaukee are slowly being removed in stream rehabilitation efforts. Water chemistry remains important, and this channel shows abundant algal growth from excess nutrients and abundant sunlight.
