This report describes the activities of the U.S. Geological Survey Water Resources Division in Texas for fiscal year 1988. The project number, cooperating agencies, project chief, period of project, location, problem, objective, approach, progress, reports in preparation, and reports published are given for each project in the Texas District. The report also includes a list of reports...

The U.S Geological Survey (USGS) compiled and analyzed existing hydrologic and water-quality data from over 200 stream and estuary stations of the Abemarle-Pamlico estuarine system (A/P) to identify long-term temporal and spatial trends. The dataset included seven stations of the USGS National Stream Quality Accounting Network, two stations of the National Atmospheric Precipitation...

Hydrologic data was collected during the 1988 water year in cooperation with the Iowa Department of Natural Resources Geological Survey Bureau in the Big Spring ground-water basin located in Clayton County, Iowa. Information on precipitation, streams, and ground water was collected in the basin. Total rainfall at Big Spring was 24.08 inches. The greatest monthly rainfall was in September...

A wide spectrum of modified nucleosides has been quantified by high-performance liquid chromatography in serum of 49 male lung cancer patients, 35 patients with other cancers, and 48 patients hospitalized for nonneoplastic diseases. Data for 29 modified nucleoside peaks were normalized to an internal standard and analyzed by discriminant analysis and stepwise discriminant analysis. A...

A combined wet chemical and dry ash digestion and use of a continuous- flow hydride generator coupled with a flame-heated quartz cell enabled the simple, precise, and highly automated atomic absorption determination of arsenic and selenium in tissues of whole fish. Percent relative standard deviation averaged 4% for each element; method detection limits (μg/g dry wt) were about 0.06 for...

As of January 1, 1989, the surface-water data-collection network in Texas included 373 continuous-streamflow, 75 continuous or daily reservoir-content, 37 gage-height, 15 crest-stage partial-record, 200 data collection platform, 7 periodic discharge through range, 27 flood-hydrograph partial-record, 27 low-flow partial-record, 43 daily chemical-quality, 17 continuous-recording water...

A statistical analysis was made of data from more than 6,200 water wells drilled in the fractured crystalline rocks of the Blue Ridge, Piedmont, and western edge of the Coastal Plain where crystalline rocks underlie sediments at shallow depths. The study area encompassed 65 counties in western North Carolina, an area of 30,544 square miles, comprising nearly two-thirds of the State...

The South Carolina District, of the U.S. Geological Survey 's Water Resources Division, conducts data collection and interpretative investigations of the water resources of South Carolina. These studies address water-resource related problems in South Carolina that are of National, State, and local interest. This report provides information on investigations in progress in the District...

Water level measurements were made in 95 wells open to the Black Creek aquifer at the end of 1986 to determine the configuration of its potentiometric surface over an area of about 4,900 sq mi in the central Coastal Plain of North Carolina. The altitude of the potentiometric surface of the Black Creek ranges between 80 and 100 ft above sea level along the western limit of the aquifer...

Four unsaturated-zone monitoring sites and a meteorologic station were installed at the low-level radioactive-waste burial site near Barnwell, S.C., to investigate the geohydrologic and climatologic factors affecting water movement in the unsaturated zone. The study site is located in the Atlantic Coastal Plain. The unsaturated zone consists of a few centimeters to more than 1 meter of...

The Camp Lejeune Marine Corps Base occupies 164 square miles in the Coastal Plain of North Carolina, including 30 square miles of the New River estuary that bisects the Base. As much as 1,500 feet of unconsolidated or partly consolidated sand, limestone, silt, and clay beds that contain seven aquifers separated by six confining units underlie the Base. Freshwater is present in aquifers
