Water chemistry studies allow USGS Texas Water Science Center (TXWSC) 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
TXWSC 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

Pecos River Basin Salinity Assessment
The USGS Texas Water Science Center assesssed salinity of the Pecos River Basin from Santa Rosa Lake, New Mexico to the confluence of Pecos River and Rio Grande, Texas. This assessment included an extensive literature review, compilation of previously published salinity related data, data gap analysis, additional data collection to fill data gaps, and identification of potential areas of elevated...
Water-Quality Monitoring of the Lake Houston Watershed
Real-time water-quality, streamflow and water height information for Lake Houston and the surrounding San Jacinto watershed are now available from a new web application from the U.S. Geological Survey, done in cooperation with the City of Houston.
San Antonio River Sediment and Water Quality Monitoring in an Oil and Gas Production Area
During 2011-2013, baseline concentrations of many different water and streambed-sediment constituents were determined at Phase I sites upstream from, within, and downstream from the area of active oil and natural-gas production within the San Antonio River Basin. With baseline conditions previously established, this study will provide current information that couples recent water and stream-bed...
Transboundary Aquifer Assessment Program (TAAP)
Many communities along the U.S.-Mexico border have limited surface water supply and rely on transboundary aquifers for industry, agriculture, and drinking water; however, information on water needs, water quality, and the extent and functioning of these aquifers is incomplete. The Transboundary Aquifer Assessment Program (TAAP), established through a binational agreement between the United States...
Edwards Aquifer Recharge Zone Surface-water and Groundwater Interaction
The effects of urbanization across the recharge zone in Bexar County and potential impact on the water quality in the Edwards aquifer is a topic of specific concern for the City of San Antonio. The USGS Texas Water Science Center is simultaneously collecting water-quality data from surface-water runoff sites and paired shallow groundwater wells within the recharge zone of the Edwards aquifer to...
Water Quality Monitoring at Offshore Artificial Reefs
USGS Texas Water Science Center scientists are collecting physical and chemical water properties at selected Texas artificial reefs to provide the initial foundation to establish the status and long-term trends in the environment and information essential for sound management decisions and long-term planning.
Nutrient and Sediment Variability in the Lower San Jacinto River
The San Jacinto River is the second largest inflow into Galveston Bay. The USGS Texas Water Science Center collects water-quality samples in the lower reaches of the San Jacinto River over a range of hydrologic conditions to improve our understanding of the variability of nutrient and sediment concentrations in freshwater inflows from the San Jacinto River into Galveston Bay.
National Water-Quality Assessment Project in Texas - Surface Water Activities
The USGS National Water-Quality Assessment (NAWQA) Project was established by Congress in 1992 to answer the following question:What is the status of the Nation’s water quality and is it getting better or worse? Since 1992, NAWQA has been a primary source of nationally consistent data and information on the quality of the Nation’s streams and groundwater. Data and information obtained from...
Hydrogeologic Framework and Geochemistry of Gaines, Terry, and Yoakum Counties
In 2014, USGS, in cooperation with Llano Estacado Underground Water Conservation District, Sandy Land Underground Water District, and South Plains Underground Water Conservation District, began a multiphase project to develop a regional conceptual model of the hydrogeologic framework and geochemistry of the Ogallala, Edwards-Trinity, and Dockum aquifers. The Ogallala aquifer is the shallowest...
Hydrogeologic Atlas for Fort Bliss
Successful long term stewardship of Fort Bliss lands includes managing traditional hydrologic resources such as surface water and groundwater resources and increasingly, geologic resources such as geothermal reservoirs and deep well injection locations. The USGS Texas Water Science Center is developing a garrison-wide hydrogeologic atlas that describes the hydrology and hydrogeology of Fort Bliss...
Cyanobacteria Methods
Texas Water Science Center (TXWSC) scientists are testing different methods of detecting and quantifying cyanobacteria and cyanotoxins in Texas reservoirs. The results of these tests could be used to develop a cost-effective monitoring plan to evaluate the presence and concentration of cyanobacteria and cyanotoxins in Texas reservoirs.
Urban Waters Federal Partnership - Edwards Aquifer Recharge Zone Monitoring Network
The USGS Texas Water Science Center is implementing a more complete and integrated monitoring network for the Edwards aquifer to improve the understanding of aquifer water quality and establish a baseline for measuring future water-quality changes.
