Measurement of time of travel and dispersion in streams by dye tracing
E. F. Hubbard, F. A. Kilpatrick, L.A. Martens, J. F. Wilson Jr.
1982, Techniques of Water-Resources Investigations 03-A9
The use of fluorescent dyes and tracing techniques provides a means for measuring the time-of-travel and dispersion characteristics of steady and gradually varied flow in streams. Measurements of the dispersion and concentration of dyes give insight into the behavior of soluble contaminants that may be introduced into a stream. This manual describes methods of measuring time...

Chemical composition of bulk precipitation in the North-Central and Northeastern United States, December 1980 through February 1981
Norman E. Peters, Joseph E. Bonelli
1982, Circular 874
Samples of bulk precipitation were collected at 179 sites in the North-Central and Northeastern United States for 3 months during winter 1980-81 to provide data on the distribution of chemical constituents. Concentrations and average daily loads of 29 dissolved constituents were determined. Sodium and chloride deposition was relatively high in...
Program for evaluating stream quality in North Carolina
Hugh B. Wilder, Clyde E. Simmons
1982, Water Supply Paper 2185-A
The design and objectives of the program for evaluating stream quality in North Carolina are described. Using water-quality and streamflow data collected since the 1940?s, a study is underway to define certain variations in water quality, to quantify the effects of man?s activities on water quality, and to determine long-term...

Landslide overview map of the conterminous United States
Dorothy H. Radbruch-Hall, Roger B. Colton, William E. Davies, Ivo Lucchitta, Betty A. Skipp, David J. Varnes
1982, Professional Paper 1183
The accompanying landslide overview map of the conterminous United States is one of a series of National Environmental Overview Maps that summarize geologic, hydrogeologic, and topographic data essential to the assessment of national environmental problems. The map delineates areas where large numbers of landslides exist and areas which are susceptible...
Water-quality characteristics of streams in forested and rural areas of North Carolina
Clyde E. Simmons, Ralph C. Heath
1982, Water Supply Paper 2185-B
Data collected in North Carolina during 1973-78 from a statewide network of 39 rural sampling sites were used to define unpolluted or baseline stream quality. The basins were 90 to 100 percent forested and, except for the unknown effects of air pollution, were relatively unaffected by man 's activities. Five...

Water quality of the Neuse River, North Carolina - Variability, pollution loads, and long-term trends
Doughlas A. Harned
1982, Water Supply Paper 2185-D
Interpretation of water-quality data collected by the U.S. Geological Survey for the Neuse River, North Carolina, has identified water-quality variations, charactrized the current condition of the river in reference to water-quality standards, estimated the degree of pollution caused by man, and evaluated long-term trends in concentrations of major dissolved constituents....
Geohydrologic appraisal of water resources of the South Fork, Long Island, New York
Bronius Nemickas, Edward J. Koszalka
1982, Water Supply Paper 2073
The ground-water resources of the South Fork of Long Island, N.Y., were investigated from April 1974 to September 1977. The study area encompasses 137 square miles and includes the eastern part of the Town of Southampton and the entire Town of East Hampton. The South Fork consists of a Paleozoic...

Map showing the potentiometric surface of the Magothy Aquifer in southern Maryland, September 1981
F. K. Mack, J. C. Wheeler, S. E. Curtin
1982, Open-File Report 82-257
The map is based on measurements from a network of 83 observation wells cased to the Magothy aquifer. Highest levels of the potentiometric surface, 59 to 60 feet above sea level, were measured near the outcrop-subcrop of the aquifer in topographically high areas of Anne Arundel and Prince Georges Counties....
