Water Chemistry Science in Oklahoma and Texas
Water chemistry studies allow USGS Oklahoma-Texas Water Science Center (OTWSC) scientists to look at what has been dissolved in the water, how different constituents in water may react together, and how constituents in water interact with the minerals along its flow path. Visit the links below for more information on our data and science.
WATER CHEMISTRY SCIENCE CAPABILITIES
OTWSC has expertise in water chemistry science applications, including, but not limited to:
- Analyzing trends in water chemistry and water quality
- Characterizing and quantify volume, suspended sediment, and nutrients in surface water
- Characterizing water-chemistry connection between surface water and groundwater
- Coupling water chemistry and stream-bed sediment data with changes in land cover
- Developing continuous regression models based on surrogate parameters to estimate water chemistry concentrations
- Developing local and regional conceptual models of geochemistry
- Integrated sampling networks including automated sampling, real-time data logging, and discrete sample collection
- Quantifying compounds using enzyme-linked immunosorbent assays (ELISA), gas chromatography, liquid chromatography, and mass spectrometry
- Low-level (parts per billion or lower) analytical techniques
- Age-date tracer testing
- Isotopic and radionuclide analysis
- Analytical methods development and testing
