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.

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.

Health-Based Screening Levels (HBSLs)

This searchable online database provides Health-Based Screening Levels (HBSLs) for hundreds of chemicals, including  pesticides and degradates. HBSLs are non-enforceable benchmark concentrations of contaminants in water. These screening levels supplement federal drinking-water standards and guidelines.
