Urban Waters Federal Partnership—Middle Rio Grande (Albuquerque, N. Mex.)

The Valle de Oro National Wildlife Refuge, just 7 miles south of downtown Albuquerque on the Rio Grande, will reconnect people, especially young people, with nature in this highly populated area. The USGS is gathering data that will help gauge the success of habitat restoration efforts.

Urban Waters Federal Partnership - Suspended Sediment and Nutrient Delivery to the Gulf of Mexico

Suspended sediment and nutrients from greater San Antonio can affect instream ecological health of the San Antonio River and ultimately impact Gulf of Mexico bays and estuaries. Real-time monitoring in urban and rural parts of the river basin may provide a glimpse into the importance of urban sediment and nutrient sources. Real-time sensors provide a tool to better understand and manage water...

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.

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.
