Ground-water quality of the southern High Plains aquifer, Texas and New Mexico, 2001
In 2001, the U.S. Geological Survey National Water-Quality Assessment Program collected water samples from 48 wells in the southern High Plains as part of a larger scientific effort to broadly characterize and understand factors affecting water quality of the High Plains aquifer across the entire High Plains. Water samples were collected primarily...

A triangular model of dimensionless runoff producing rainfall hyetographs in Texas
A synthetic triangular hyetograph for a large data base of Texas rainfall and runoff is needed. A hyetograph represents the temporal distribution of rainfall intensity at a point or over a watershed during a storm. Synthetic hyetographs are estimates of the expected time distribution for a design storm and principally are used in small watershed...

Volatile organic compound and pesticide data in public water-supply reservoirs and wells, Texas, 1999-2001
To provide data for the Texas Source-Water Assessment and Protection Program, the U.S. Geological Survey conducted a synoptic survey of 48 public water-supply reservoirs and 174 public water-supply wells during 1999–2001. The surface-water samples were analyzed for volatile organic compounds and soluble pesticides. The ground-water samples were...

Water quality in south-central Texas, 1996-98
This report summarizes major findings about water quality in south-central Texas that emerged from an assessment conducted between 1996 and 1998 by the U.S. Geological Survey (USGS) National Water-Quality Assessment (NAWQA) Program. Water quality is discussed in terms of local and regional issues and compared to conditions found in all 36...

Gas and Isotope Geochemistry of 81 Steam Samples from Wells in The Geysers Geothermal Field, Sonoma and Lake Counties, California
The Geysers geothermal field in northern California, with about 2000-MW electrical capacity, is the largest geothermal field in the world. Despite its importance as a resource and as an example of a vapor-dominated reservoir, very few complete geochemical analyses of the steam have been published (Allen and Day, 1927; Truesdell and others,...

Water Quality Assessment of the Comal Springs Riverine System, New Braunfels, Texas, 1993-94
Comal Springs of Central Texas are the largest springs in the southwestern United States. The long-term average flow of the Comal River, which essentially is the flow from Comal Springs, is 284 cubic feet per second (ft3/s). The artesian springs emerge at the base of an escarpment formed by the Comal Springs fault. The Comal River (fig. 1) is...

Water-quality summary of the San Marcos Springs Riverine System, San Marcos, Texas, July-August 1994
San Marcos Springs is the second largest spring in Texas and is the headwaters for the San Marcos River in San Marcos. Spring Lake (fig. 1) was built in 1848 at the site of a marsh formed by the springs to provide hydropower to a mill. The San Marcos River originates from the 15-acre lake and flows approximately 4 river miles (mi) south to its...

Procedures for collecting and analyzing gas samples from geothermal systems
Fahlquist, Lynne S.; Janik, Cathy J. Hydrogeochemical exploration of geothermal prospects in the Tecuamburro Volcano region, Guatemala
Chemical and isotopic analyses of thermal and nonthermal waters and of gases from springs and fumaroles are used to evaluate the geothermal potential of the Tecuamburro Volcano region, Guatemala. Chemically distinct geothermal surface manifestations generally occur in separate hydrogeologic areas within this 400 km2 region: low-pressure fumaroles...

USGS Releases New JavaScript Library to Create Location Search Widgets for Web Applications
The U.S. Geological Survey Search API is a custom JavaScript library useful for creating a location search widget in a webpage, typically in conjunction with a web map. The widget connects to a database created for the API, or Application-Programming Interface, to quickly find and suggest locations as the user enters text to navigate to areas of interest.
New App Shows Aquifer Level Change and Subsidence in Relation to Groundwater Withdrawals in Houston-Galveston Area
A new interactive web application illustrates how groundwater, sediment compaction and land-elevation change are related in the Houston-Galveston region in Texas. The new app was developed by the U.S. Geological Survey and is available online.
New “Water On-the-Go” App Helps Keep Texans Safe with Current Stream Conditions
The new “Water On-the-Go” mobile app gives the public easy access to current conditions in streams across Texas. This product was developed by the U.S. Geological Survey to help raise water awareness during both floods and normal conditions.
Sediment Flows into Galveston Bay Studied to Help Understand Health of Watershed
A better understanding of sediment and freshwater flow into Galveston Bay is now available from a new U.S. Geological Survey report, done in cooperation with the Texas Water Development Board, and the Galveston Bay Estuary Program.
Land Elevation Changes Due to Groundwater Withdrawals Indicate Regional Shifts in Houston-Galveston Area
New Report Marks 40 Years of Subsidence Investigations
USGS Releases New JavaScript Library for Plotting Water Data for the Nation
A new JavaScript library, called GWIS (Graphing Water Information System), can create time-series plots of information measured at U.S. Geological Survey hydrologic data collection sites across the United States.
Streamflow and Springflow Data for Comal and San Marcos Rivers, Texas Now Available Online
A new U.S. Geological Survey website provides important information about streamflow in the Comal and San Marcos Rivers and springflow at Comal and San Marcos Springs. This website was developed in collaboration with the Edwards Aquifer Authority.
