Watershed- and Regional Scale Contamination

The Redwood River, Minnesota, with a plume of water dyed red with rhodamine dye.
Scientists used florescent dye and bromide to track river water to which two emerging contaminants had been added - 4-nonylphenol and 17β-estradiol. This allowed the scientists to study the natural attenuation of the two compounds as they were transported down the Redwood River, Minnesota. Photo credit: Jeffrey H.
