Learn about trends in contaminants in the nation’s streams and rivers, trends in contaminants that collect in the bed sediment of streams and lakes, and changes in the quality of the nation’s groundwater.

Sediment-Associated Contaminants

Stream, river, and lake bed sediment are reservoirs for many contaminants.  These contaminants include some “legacy” contaminants, like DDT, PCBs, and chlordane, and chemicals currently in use, like the insecticide bifenthrin and many flame retardants.  Learn about techniques used to study sediment-associated contaminants and their importance to aquatic biota.
