Sediment Fingerprinting in Langdon Park
It’s not just the big rivers and streams. USGS MD-DE-DC Water Science Center scientists also collect samples from local parks. Zach and Leah collect sediment auger samples from Langdon Park in Washington DC as part of a study to find the sources of sediment runoff. The sediment will later be analyzed at in-house and third-party labs for geochemical signatures in a process known as sediment fingerprinting.
