Dissolved Solids Sources, Loads, and Yields For the Conterminous U.S.

Using the SPARROW (SPAtially-Referenced Regression on Watershed Attributes) model, long-term mean annual conditions for dissolved-solids sources, loads, and yields were predicted for nearly 66,000 stream reaches and their corresponding incremental catchments that drain the Nation.

Watershed Regressions for Pesticides (WARP)

The Watershed Regression for Pesticides (WARP) is an online tool that allows users to estimate pesticide concentrations for streams that have not been monitored. WARP models are developed using linear regression methods to establish quantitative linkages between measured pesticide concentrations and a variety of human-related and natural factors that affect pesticides in streams.

Volatile Organic Compounds in Samples from Domestic and Public Wells, 1985–2002

The U.S. Geological Survey’s (USGS) National Water-Quality Assessment (NAWQA) Program recently completed a national study of volatile organic compounds (VOCs) in the Nation’s ground water (Zogorski and others, 2006). Part of this assessment emphasizes the occurrence of 55 VOCs in samples from 2,401 domestic wells and 1,096 public wells during 1985–2002.

Current Streamflow and Water-Quality Monitoring at Select Sites in the Animas and San Juan River Basins, Colorado, New Mexico, and Utah

The USGS monitors current streamflow and water-quality conditions at various sites in the Animas and San Juan River Basins in Colorado, New Mexico, and Utah, including areas below the Gold King Mine release area. These streamgages provide continuous data on streamflow and select water-quality constituents including specific conductance, water temperature, pH, and turbidity.

Predicted pH at the domestic and public supply drinking water depths, Central Valley, California

This scientific investigations map is a product of the U.S. Geological Survey (USGS) National Water-Quality Assessment (NAWQA) project modeling and mapping team. The prediction grids depicted in this map are of continuous pH and are intended to provide an understanding of groundwater-quality conditions at the domestic and public supply drinking water zones in the groundwater of the Central Valley.

Assessing Endocrine Disrupting Chemicals Risk In U.S. National Parks

Endocrine disrupting chemicals (EDC) threaten the reproductive success and long-term survival of sensitive aquatic populations in the U.S. National Park Service (NPS). The project employs a standardized EDC risk assessment framework to link new and ongoing research efforts in individual Parks and in Park Monitoring Networks, in order to provide a service-wide assessment of EDC risk in the NPS.

Great Lakes SPARROW Mapper, 2002

This mapper displays SPARROW nutrient load and yield data specifically for U.S. tributaries to the Great Lakes. The results are based on the SPARROW models developed for the Great Lakes, Ohio, Upper Mississippi, Red River Basins (MRB3). Modeling results can be exported as an Excel spreadsheet or a geospatial dataset.
