This report is one in a series of reports that depict altitudes of water levels since 1977, the most recent of which (Barbie and other, 1989) presented maps of the altitudes of water levels for 1989. This report was prepared in cooperation with the City of Houston and the Harris-Galveston Coastal Subsidence District, and presents approximate altitudes of water levels in wells in the...

This report is one in a series of reports that depict water-level changes and compaction of subsurface material in the Houston-Galveston region. The maps present approximate water-level changes in wells in the Chicot and Evangeline aquifers, 1977-91 and 1990-91 (figs. 1-4). The location of borehole extensometers is shown in figure 5, and graphs present measured compation for 1973-90 (fig...

In 1991, the U.S. Geological Survey (USGS) began to implement a full-scale National Water-Quality Assessment (NAWQA) program. The long-term goals of the NAWQA program are to describe the status and trends in the quality of a large, representative part of the Nation's surface- and ground-water resources and to provide a sound, scientific understanding of the primary natural and human...

Data for water wells and ground water in Brazoria, Fort Bend, and Waller Counties were collected during 1985-89 by the U.S. Geological Survey. This report presents a compilation of records for 32 wells in Brazoria County, 19 wells in Fort Bend County, and 16 wells in Waller County. Drillers' logs for 65 wells, water levels for 85 wells, chemical analyses of water for 9 wells, and water...

Data for water wells and ground water in Chambers, Liberty, and Montgomery Counties were collected during 1985-89 by the U.S. Geological Survey. This report presents a compilation of records for 4 wells in Chambers County, 8 wells in Liberty County, and 64 wells in Montgomery County. Drillers' logs of 60 wells, water levels for 84 wells, chemical analyses of water for 11 wells, and water...

A complex, multilayered ground-water flow system exists in the Coastal Plain sediments of Texas. The Tertiary and Quaternary clastic deposits have an areal extent of 114,000 square miles onshore and in the Gulf of Mexico. Two distinct aquifer systems are recognized within the sediments, which range in thickness from a few feet to more than 12,000 feet The older system--the Texas coastal...

This report presents data on water-level changes during 1990-90 in the Chicot and Evangeline aquifers (figs. 1-2) in Fort Bend County.

Since 1950, the U.S. Geological Survey (USGS) has estimated water use in the United States at 5-year intervals. Resulting reports tabulate water use by State and by water-resources region (major river basins) for a number of categories, such as irrigation, water supply, and industrial. In 1977, the USGS began the National Water-Use Information Program, designed to be a National source of

The potentiometric surface of the Edwards-Trinity aquifer system and contiguous hydraulically connected units (from December 1974 through February 1975) was mapped as part of the Edwards-Trinity Regional Aquifer-System Analysis (RASA) project. A major goal of the Edwards-Trinity RASA project is to understand and describe the regional flow system (Bush, 1986). The development of a digital...

The U.S. Geological Survey (USGS), in cooperation with the city of Dallas, conducted a study of the time of travel of solutes during moderate flow conditions in a reach of the Trinity River from the outfall of the Dallas Central Wastewater Treatment Plant (DCWTP) to the USGS streamflow-gaging station 08062700, Trinity River at Trinidad, in May and August 1987. Previous USGS time-of...
