Water resources of the Myakka River basin area, southwest Florida
Boyd F. Joyner, Horace Sutcliffe Jr.
1976, Water-Resources Investigations Report 76-58
Ground water in the Myakka River basin area of southwest Floria is obtained from a water-table aquifer and from five zones in an artesian aquifer. Wells in the water-table aquifer yield generally less than 50 gpm and dissolved solids concentration is less than 500 mg/liter except in coastal areas and...
Availability and chemical characteristics of ground water in central La Plata County, Colorado
R. E. Brogden, T.F. Giles
1976, Water-Resources Investigations Report 76-69
The central part of La Plata County, Colo., has undergone rapid population growth in recent years. This growth has resulted in an increased demand for information for additional domestic, industrial, and municipal water supplies. A knowledge of the occurrence of ground water will permit a more efficient allocation of the...
Summary of geology and ground-water resources of Passaic County, New Jersey
L.D. Carswell, J.G. Rooney
1976, Water-Resources Investigations Report 76-75
Ground water in Passaic County occurs in intergranular openings of unconsolidated stratified deposits of Quaternary age and in joints and fractures in consolidated rocks of Precambrian, Paleozoic, and Triassic age.The Brunswick Formation of Triassic age is the most important aquifer in the southeastern one-third of Passaic County. Reported yields of public supply and...
The Meridian-upper Wilcox aquifer in Mississippi
E. H. Boswell
1976, Water-Resources Investigations Report 76-79
The Meridian-upper Wilcox aquifer contains freshwater in a 15 ,000 sq mi area in northwestern and central Mississippi. The aquifer comprises the Meridian Sand Member of the Tallahatta Formation and discontinuous hydraulically connected sand beds in the upper part of the Wilcox Group. The aggregate sand thickness of the aquifer...
Analytical precision of one-sixth order semiquantitative spectrographic analysis
J. M. Motooka, D. J. Grimes
1976, Circular 738
Over 2,700 separate analyses were made on 22 different geologic samples selected to cover wide concentration ranges for the 30 elements studied. The precision for low, medium, and high concentrations of each element determined is represented by superimposed frequency diagrams and displays the frequency of reported values occurring within one-sixth...
Technical manual for estimating low-flow frequency characteristics of streams in the Susquehanna River basin
Jeffrey T. Armbruster
1976, Water-Resources Investigations Report 76-51
This report presents procedures for estimating low-flow frequency characteristics for streams in the Susquehanna River basin. The techniques can be used at ungaged sites as well as sites where insufficient data are available to make a reliable estimate. Streams have been divided intp two types--major and minor. Major streams are...
