PDF Chloride control and monitoring program in the Wichita River Basin, Texas, 1996-2009 [More info]
Chloride concentrations in this river have historically been high due to natural saltwater springs and seeps from geologic formations. We monitor the water to help assess the progress of human efforts designed to mitigate this problematic salinity.
PDF Methods for estimating concentrations and loads of selected constituents in tributaries to Lake Houston near Houston, Texas [More info]
Water from this reservoir will be used more extensively by the city, so we are developing methods of assessing the water quality in real time by measuring characteristics of stream flow that correlate with important water quality data.
Water resources of Virginia - chloride monitoring network [More info]
Description of project to study the distribution of saline water in the aquifers of the Coastal Plain of Virginia and the potential for saline water intrusion by evaluating chloride concentrations and the factors affecting chloride distribution.
Dissolved solids in basin-fill aquifers and streams in the southwestern United States [More info]
PDF Examination of brine contamination risk to aquatic resources from petroleum development in the Williston Basin [More info]
Wetlands and oil wells shouldn't mix, but in some areas they do. This explains what problems may arise and how we study the effects of highly salty water produced by oil wells when it leaks into nearby wetlands and streams.
Groundwater quality in the Monterey Bay and Salinas Valley groundwater basins, California [More info]
This study of untreated groundwater indicates the number of samples in which inorganic or organic constituents occur in high or moderate in concentration. The study does not indicate significant problems in groundwater quality here.
Groundwater quality in the San Francisco Bay groundwater basins, California [More info]
The constituent present at high concentrations in the greatest proportion of the primary aquifer system was TDS, which is an indicator of salinity. Perchlorate was also present at moderate concentration in 42% of samples.
Groundwater quality in the Santa Clara River Valley, California [More info]
This study of untreated groundwater indicates the number of samples in which inorganic or organic constituents occur in high or moderate in concentration. The study does not indicate significant problems in groundwater quality here.
PDF Groundwater quality of southeastern Wyoming [More info]
Explains how we assess groundwater quality here, what characteristics are important, and how they hurt or, in some cases, help use use the water.
Hudson River salt front data [More info]
Tide stage, specific conductance, water temperature, and freshwater inflow at selected Hudson River (New York) gages updated every 4-hours to measure the effects of freshwater withdrawals and upstream movement of the salt front.
PDF Relations among land cover, streamflow, and water quality in the North Canadian River Basin near Oklahoma City, Oklahoma: 1968-2009 [More info]
Data explains spatial differences and temporal trends in water quality, specifically dissolved oxygen, nitrogen and phosphorus concentrations.
PDF Response of lake chemistry to atmospheric deposition and climate in selected Class I wilderness areas in the western United States, 1993-2009 [More info]
Sulfate deposition to high-elevation areas has decreased here as a result of reductions in SO2 emissions. Nitrate deposition did not change, whereas ammonium deposition increased, particularly at sites near urban and agricultural areas.
South Florida Ecosystem History Project [More info]
Project is designed to integrate studies from a number of researchers compiling data from terrestrial, marine, and freshwater ecosystems within south Florida. Links to publications, maps, posters, and data of studies.
