Brian Selck, a USGS National Association of Geoscience Teachers intern, collects a water level measurement from a domestic well at a site north of Jersey Shore in Lycoming County, Pennsylvania, June 2014.

Both irrigation wells and municipal wells affect water levels in the Little Plover River, Wisconsin.

Screen capture of ModelMuse with an object used in Surface Water Routing and the words "Now I've set up a very simple Surface Water Routing process model.

Screen capture of ModelMuse with "The other way to define observations is with the SWR Observations dialog box."

Screenshot of ModelMuse with "The Surface Water Routing process has a special way of specifying some transient data."

Screen capture of ModelMuse with the Data Visualization dialog box open to "SWR Observations".

USGS hydrologist Kaitlyn Colella and a Shinnecock Nation member work together gathering oyster and bed sediment samples.  Contaminants released and or mobilized as a result of Hurricane Sandy may be retained in bed sediments in aquatic environments and may be accumulating in exposed organisms, especially at low trophic levels (for example, oysters).

Screen capture of the ModelMuse "MODFLOW Packages and Programs" dialog box with the words "In the Surface Water Routing process, there are two different ways to specify rainfall, evaportation, lateral inflow, and stage."
