As part of the USGS's national reconnaissance of the occurrence of emerging contaminants in source waters, scientists collected water samples near intake structures for water-supply plants. Here a USGS technician on a water-quality sampling boat is operating a crane with a water-quality sampler attached -- Duck River, TN.
