Geology and hydrology of the West Milton area, Saratoga County, New York
Frederick K. Mack, F. H. Pauszek, John R. Crippen
1964, Water Supply Paper 1747
This report describes the geology, ground-water conditions, streamflow characteristics, and quality of water in the West Milton area, Saratoga County, N.Y. The West Milton area is in the east-central part of New York in the hilly region that forms a transition zone between the Adirondack Mountains and the Hudson-Mohawk valley...
Geology and ground-water resources of Washington County, Colorado
Harold E. McGovern
1964, Water Supply Paper 1777
Washington County, in northeastern Colorado, has an area of 2,520 square miles. The eastern two-thirds of the county, part of the High Plains physiographic section, is relatively flat and has been moderately altered by the deposition of loess and dune sand, and by stream erosion. The western one-third is a...
Quality of Delaware River water at Trenton, New Jersey
Leo T. McCarthy Jr., Walter B. Keighton
1964, Water Supply Paper 1779-X
Water in the Delaware River at Trenton, NJ, is a mixture of several types--water from the mountainous headwater region, water from the coal-mining regions, and water from the limestone valleys. The quantities of these types of water, in relation to the total quantity of water at Trenton, vary with changes...
Ground-water geology of the Dickson, Lawrenceburg, and Waverly areas in the western Highland Rim, Tennessee
Melvin V. Marcher, Roy H. Bingham, Richard Edwin Lounsbury
1964, Water Supply Paper 1764
Ground-water supplies in the Dickson, Lawrenceburg, and Waverly areas are obtained from wells and springs in limestone and chert formations of Missisippian age. In the Dickson area most of the wells and springs are in Warsaw Limestone. In the Lawrenceburg and Waverly areas, ground-water supplies are obtained from Fort Payne...
Geology and ground-water conditions in the Wilmington-Reading area, Massachusetts
John Augustus Baker, H.G. Healy, O. M. Hackett
1964, Water Supply Paper 1694
The Wilmington-Reading area, as defined for this report, contains the headwaters of the Ipswich River in northeastern Massachusetts. Since World War II the growth of communities in this area and the change in character of some of them from rural to suburban have created new water problems and intensified old...
Ground-water resources of the lower Rio Grande Valley area, Texas
R. C. Baker, O.C. Dale
1964, Water Supply Paper 1653
The report contains information about the occurrence, quality, and use of ground water in the Lower Rio Grande Valley area which consists of Cameron, Hidalgo, Starr, and Willacy Counties in southern Texas. The principal use of water in the area is for irrigation. The principal irrigated crops are cotton, winter vegetables,...
Determination of radium in water
Franklin Butt Barker, J. O. Johnson
1964, Water Supply Paper 1696-B
Radium isotopes are common radioactive constituents of natural waters. The concentration of radium-226 in potable water is of particular significance because this isotope is generally considered the most hazardous of all radionuclides with respect to ingestion. The approximate concentration of radium-226 is determined after coprecipitating radium with barium sulfate. The...
Field measurement of alkalinity and pH
Ivan Barnes
1964, Water Supply Paper 1535-H
The behavior of electrometric pH equipment under field conditions departs from the behavior predicted from Nernst's law. The response is a linear function of pH, and hence measured pH values may be corrected to true pH if the instrument is calibrated with two reference solutions for each measurement. Alkalinity titrations...
Methods of determining permeability, transmissibility and drawdown
Ray Bentall
1964, Water Supply Paper 1536-I
If the Theis graphical method is used for determining the hydraulic constants of an aquifer under water-table conditions, the observed drawdowns should be corrected for the decrease in saturated thickness. This is especially true if the drawdown is a large fraction of the original saturated thickness, for then the computed...
Ground-water resources of Waupaca County, Wisconsin
Charles F. Berkstresser
1964, Water Supply Paper 1669-U
Waupaca County is in east-central Wisconsin. No serious ground-water problems existed in 1960 except in a few localities where crystalline rock is near land surface or is covered by nearly impermeable till. The use of ground water for irrigation has not appreciably affected ground-water levels. The county is covered by Pleistocene...
Geology and ground-water resources of southeastern New Hampshire
Edward Bradley
1964, Water Supply Paper 1695
The continued growth and development of southeastern New Hampshire, an area of about 390 square miles adjacent to the Atlantic Ocean, will depend partly on effectively satisfying the demand for water, which has increased rapidly since World War II. The report identifies and describes the principal geologic units with respect...
