PDF Nitrate concentrations and potential sources in the Barton Springs segment of the Edwards aquifer and its contributing zone, Central Texas [More info]
The area contributing recharge to this aquifer is undergoing rapid growth, generating more wastewater. We found that nitrate, a major component of wastewater and a nutrient that can degrade water quality, has increased in the creeks in this area.
Nutrients National Synthesis Project: nutrients in rivers, streams, and aquifers in the United States [More info]
This Nutrients National Synthesis Project site on the U.S. study of nutrients, especially nitrogen and phosphorus, as contaminants in high concentrations links to an overview, study team, featured reports, publications, and national datasets.
PDF Organic Compounds in Clackamas River Water Used for Public Supply near Portland, Oregon, 2003-05 [More info]
In all, 56 compounds were detected in samples collected approximately monthly during 2003-05 at the intake for the Clackamas River Water plant. On the basis of this screening-level assessment, adverse effects to human health are assumed to be negligible.
Pesticide National Synthesis Project: national assessment of pesticides in streams, rivers, and ground water of the United States [More info]
An assessment of pesticides in national water resources, with links to national reports, national statistics, national data, pesticide use, analytical strategy, and standards for the U.S.
Pharmaceuticals, Hormones, and Other Organic Wastewater Contaminants in U.S. Streams [More info]
Describes and illustrates that a broad range of chemicals found in residential, industrial, and agricultural wastewaters commonly occur in mixtures at low concentrations downstream from areas of intense urbanization and animal production.
Photographs and videos from the Upper Midwest Ecological Science Center [More info]
Aerial photography for the Upper Mississippi River System (UMRS). Mosaics of 2000 UMRS aerial photos, 1997 oblique photos collected between Minneapolis and the Gulf of Mexico, and 1994 UMRS color infrared aerial photos.
Presettlement and contemporary vegetation patterns along two navigation reaches of the Upper Mississippi River [More info]
Study to reconstruct presettlement vegetation patterns along two navigation reaches of the Upper Mississippi.
Real-time water-quality monitoring and regression analysis to estimate nutrient and bacteria concentration in Kansas streams. [More info]
Report on the use of regression equations from measurements made by water quality monitors and analytical results of manually collected samples estimating nutrient, bacteria, and other constituent concentrations to study streams in Kansas.
PDF Relations among geology, physiography, land use, and stream habitat conditions in the Buffalo and Current River systems, Missouri and Arkansas [More info]
River corridor habitat dynamics, Lower Missouri River [More info]
Detailed description of The Lower Missouri River Corridor Habitat Dynamics Project studying river habitat in a heavily engineered river.
