Linking Selenium Sources to Ecosystems: Local and Global Perspectives

The sources, biogeochemistry, and ecotoxicology of selenium (Se) combine to produce a widespread potential for ecological risk such as deformities in birds and fish. Linking the understanding of source characteristics to a mechanistic, biodynamic dietary model of Se exposure on an ecosystem-scale improves the prediction of Se effects and its potential remediation.

National Water Census: Regional Groundwater Availability Studies

The National Water Census includes regional analysis of groundwater availability, enabling information to be integrated and consistent so the resource can be analyzed and understood on an aquifer–wide scale.  The NWC also seeks to increase capacity to integrate groundwater and surface water into watershed-level assessments of water availability.

National Water Census: Collaboration

Collaboration is a critical part of the USGS National Water Census. It not only helps direct USGS efforts towards assessments that are most useful for end users – such as other Federal, State, regional, local, and tribal resource managers, but it also ensures that information produced by the USGS can be aggregated and assimilated with other types of physical, social, economic, and...

Historical Flooding

The USGS provides practical, unbiased information about the Nation's rivers and streams that is crucial in mitigating hazards associated with floods. This site provides information about the USGS activities, data, and services provided during regional high-flow events, such as hurricanes or multi-state flooding events. The USGS response to these events is typically managed by the National...

Red River Focus Area Study

The USGS is undertaking a 3-year study of water use, availability, and change in the Red River basin, which covers more than 93,000 square miles in New Mexico, Texas, Oklahoma, Arkansas, and Louisiana. Water resources are being stressed by increasing water demands and increasingly severe droughts, and a comprehensive water-resource assessment of the basin is needed to enable sustainable water...

Rapid Fluctuations in Groundwater Quality

We think of groundwater as moving slowly, and groundwater quality as changing slowly—over decades or even centuries. But in some parts of some aquifers, groundwater quality can fluctuate rapidly, sometimes over just a few hours. Are such changes part of a long-term trend, or just part of a short-term cycle? And what does that mean for suitability for drinking?
