Flood-inundation areas and depths for the Withlacoochee River in Lowndes County, Georgia from Skipper Bridge Road to St. Augustine Road

Digital flood-inundation maps for a 12.6-mile reach of the Withlacoochee River from Skipper Bridge Road to St. Augustine Road, Lowndes County, Georgia, were created by the U.S. Geologicay Survey (USGS) in cooperation with the city of Valdosta and Lowndes County, Georgia. The inundation maps, which can be accessed through the USGS Flood Inundation Mapping Science Web site at http:%

Occurrence and Concentrations of Trace Elements in Discrete Tapwater Samples Collected in Chicago, Illinois and East Chicago, Indiana, 2017

This dataset contains the trace element concentration results for samples collected from tapwater sites in East Chicago, Indiana, August-September, 2017, and Chicago, Illinois, July-December, 2017. Samples were collected one time, from 45 private residences and associated drinking water plants and source water locations. Water-quality samples were analyzed at two U.S. Geological S

Mississippi Alluvial Plain Extent, November 2017

The Mississippi Alluvial Plain (MAP) has become one of the most important agricultural regions in the US, and it relies heavily on a groundwater system that is poorly understood and shows signs of substantial change. The heavy use of the available groundwater resources has resulted in significant groundwater-level declines and reductions in base flow in streams within the MAP. These impacts...

Groundwater/Surface-Water Interactions Along Ellerbe Creek in Durham, North Carolina, 2016–18

A hydrologic study involving the investigation of groundwater-surface water interactions along Ellerbe Creek, a major tributary to upper Falls Lake, was conducted in order to determine if groundwater is a likely source of nitrate input to the stream. Groundwater-surface water interactions were characterized by synoptic streamflow measurements, groundwater-level monitoring, hydrograph-sepa

Concentrations of Pesticides, Pharmaceuticals, Organic Waste Indicators, and Volatile Organic Chemical Contaminants and Their Predicted Effects Potential in Wadeable Southeastern USA Streams

This dataset presents the results of 475 unique organic compounds collected from 54 wadeable streams within the Southeastern, USA, collected within 10 weeks during 2014. Maximum and median exposure conditions were evaluated in relation to watershed characteristics and for potential biological effects. This dataset contains the summary statistics (maximum and median concentrations)of dete

Wells sampled for groundwater-age dating in New Hanover County, North Carolina

Sulfur hexafluoride (SF6) is a trace atmospheric gas that is primarily of anthropogenic origin but also occurs naturally in fluid inclusions in some minerals and igneous rocks, and in some volcanic and igneous fluids. SF6 has been used as a dating tool of groundwater because atmospheric concentrations of SF6 are expected to continue increasing (Busenberg and Plummer, 1997). SF6 sample

Stream Channel and Floodplain Metric Toolbox

The Stream Channel and Floodplain Metric Toolbox was developed to demonstrate the feasibility of mapping fluvial geomorphic features from high-resolution bare-earth elevation data. A Python toolbox for ArcGIS was built to calculate key metrics describing channel and floodplain geometry. Channel and Floodplain Metric Toolbox provides this ability in an automated fashion, allowing for regional...
