Description:
The groundwater–surface water interface (GSWI), consisting of shallow groundwater adjacent to stream channels, is a hot spot for nitrogen removal processes, a storage zone for other solutes, and a target for restoration activities. Characterizing groundwater-surface water interaction (GSI) is difficult because of physical obstacles to sampling. Furthermore, urbanization and land-use change can impair water quality by influencing GSI. We present study results from high-resolution surface-water nutrient sampling (“sampling slam”) that helped to reveal GSI and biochemical patterns in heavily impacted urbanizing streams in the Chesapeake Bay watershed in Maryland (MD) and Pennsylvania (PA), USA.
