Urban Waters Federal Partnership—Patapsco Watershed (Baltimore, Md. region)

Several watersheds in the Baltimore region have elevated PCB loads in tidal waters. Local jurisdictions are responsible for reducing PCB loading from their watersheds. The USGS is embarking on a pilot study in the Patapsco watershed that will help determine sources of PCBs and will demonstrate innovative monitoring and analysis techniques for more efficient use of mitigation resouces.

Urban Waters Federal Partnership—Middle Blue River Basin (Kansas City, Mo.)

Reconnecting people and water is an increasingly important goal in many urban areas. Parks, urban trails, boat ramps, and urban agriculture all are ways that an urban population can interact with nature and improve quality of life.  USGS is participating in gathering the information that will make these projects possible.

National Water-Quality Project Sampling Methods

USGS National Water Quality Assessment (NAWQA) studies require analyses of stream and bed-sediment samples for major ions, nutrients, sediments, and organic contaminants that are consistent across time and space. Procedures have been designed specifically to produce...

Regional SPARROW Model Assessments of Streams and Rivers

Regional SPARROW Model Assessments of Streams and Rivers (archived) includes models (and supporting data) that were developed for seven large regions of the conterminous United States. Results from the models can be used to compare nutrient sources and watersheds that contribute elevated nutrient loads to...

Handheld Thermal Imaging Cameras for Groundwater/Surface-Water Interaction Studies

USGS scientists are using high-resolution handheld thermal imaging cameras in groundwater/surface-water interaction studies and other investigations. These cameras are used to quickly locate and characterize thermal anomalies in streams, lakes, and adjacent structures. Variations in temperature can be used to track the heat carried by flowing water, such groundwater discharge into a stream....

What does groundwater have to do with ice in Alaska?

USGS scientists are working alongside university researchers in Alaska to understand how groundwater and permafrost conditions change over time due to seasonal variations and climate change. Changes in permafrost can pose a threat to built infrastructure (like roads, homes, and pipelines) and to valued ecological resources that provide important habitats for wildlife.

Spectral Gamma Borehole Logging

Spectral gamma borehole geophysical methods measure natural-gamma energy spectra, which are caused by the decay of uranium, thorium, potassium-40, and anthropogenic radioactive isotopes. Spectral gamma data can be used to identify and quantify the amount of uranium, thorium, and potassium-40 isotopes detected in boreholes.

Geophysics for USGS Groundwater/Surface Water Interaction Studies

Understanding the interaction of groundwater and surface water is essential to water managers and hydrologists for the development of effective water-resource policy, protection, and management. The USGS conducts applied research to evaluate the use of new or emerging hydrogeophysical tools and methods to improve our understanding of groundwater/surface-water exchange.
