View of Old Mans Creek near Iowa City, Iowa upstream from a bridge used for collecting water-quality samples (USGS Site ID: 05455100).

Western view toward the Red Mountains near Silverton, Colorado, taken just upstream from the North Fork Cement Creek drainage in 2006. The photo illustrates acidic drainage (red drainage at right) and less acidic drainage (white drainage at left of photo) that originates from altered rocks and mines in the watershed.

A map showing the locations of decision units surrounding the Canyon Mine, Arizona. The scientists used a incremental sampling methodology to collect samples from the predefined decision units. The points (squares and circles) indicate locations where surface soil subsamples were collected during June 2013.

A comparison of streamflow and specific conductance (a measure of salinity) in Muddy Creek, Wyoming, for individual years from 2005 to 2012. Salt content decreases as streamflow increases, a common pattern in semiarid watersheds.
