Mine Drainage

As settlers traveled west and mined the American landscape, thousands of new mines were created over the centuries and then abandoned. Now, these long forgotten remnants of a bygone area still haunt us, as their operations left behind materials and rock exposures that can be easily eroded and carried downstream. The USGS helps track the sources of acidic mine drainage and helps land managers...

Streamflow Alteration

Humans, just like aquatic organisms, need water.  Flood control, urban infrastructure, irrigation of agriculture, and myriad other ways we manage water affect the natural flow of streams and rivers.  How do the ways we manage land and water affect the natural patterns of streamflow that ecosystems depend on?

Radionuclides

Many people might be surprised to learn that drinking-water sources, especially groundwater, can contain radioactive elements (radionuclides). Radionuclides in water can be a concern for human health because several are toxic or carcinogenic. Other radionuclides are useful tools for determining the age of groundwater in an aquifer or of sediment deposited at the bottom of a water body.

Water-Quality Benchmarks for Contaminants

How does the water quality measure up?  It all depends on what the water will be used for and what contaminants are of interest.  Water-quality benchmarks are designed to protect drinking water, recreation, aquatic life, and wildlife.  Here you’ll find links to some of the most widely used sets of water, sediment, and fish tissue benchmarks and general guidance about their interpretation.

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...

Flood Inundation Mapping Toolbox

The FIM Toolbox contains comprehensive information on the Flood Inundation Mapping program, including how to develop a flood inundation map library. Resources include process documents, scientific and technical requirements, forms and templates, outreach and educational materials, and contact information. The FIM Toolbox is updated as new resources become available.

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...

Trace Metals in San Francisco Bay Clams

The clams Potamocorbula amurensis and Corbicula fluminea were collected at a variety of sites in the San Francisco Bay/ Delta beginning July 1990 and ending February 2010. These invasive species were used as biosentinels of the fate, transport, and effects of trace metals in the San Francisco Bay ecosystem.
