Purpose and scope: This report describes the relationship between geology and ground-water occurrence in Oswego County and indicates how much ground water is likely to be available in any given area. It is a companion to a series of 29 maps produced during 1978-80^1 to document the surficial deposits in the county's 29 quadrangles and includes a compilation of data on representative wells in each quadrangle.

Abstract: Based on the records of several hundred deep wells, contour maps have been prepared showing the monoclinal structure of part of western New York, and isopach lines have been drawn showing the westward convergence of the rocks. The mode of occurrence of natural gas in the Medina group is briefly discussed. The location of the gas fields has not been determined by structural traps, but rather stratigraphy and lithology are the controlling factors in trapping the gas, which occurs in porous lenses and streaks of sandstone sealed within impermeable beds. This mode of occurrences of the Medina gas makes the search for new fields in western New York more hazardous than in most natural gas regions. As structure has not formed traps for the gas there is no surface guide to favorable sites for testing, and new fields are found by haphazard drilling. It would be helpful, however, when wells are sunk, to study the lithology of the gas-bearing zone by an examination of the drill cuttings and core samples of the sand and to have electrical logs made of the wells to obtain measurements of permeability and porosity. Such tests may indicate the direction of greatest porosity in …

Purpose and scope: This report depicts in detail the areal extent, altitude, thickness, and lithology of the "20-foot" clay and Gardiners Clay (the two thickest and most extensive near-surface confining layers in the area) and redefines the surface of the geologic units that directly underlie these clay units at various locations--the Matawan Group-Magothy Formation, undifferentiated, the Monmouth Group, and the Jameco Gravel.

Purpose and scope: The Meadowbrook artificial-recharge project, a cooperative effort between the U.S. Geological Survey and the Nassau County Department of Public Works (NCDPW) since 1975, is intended to demonstrate the feasibility of using reclaimed wastewater to replenish and improve the quality of Long Island's ground water. This report presents the results of geologic, hydrologic, and hydrochemical studies that were done at the Meadowbrook artificial-recharge site to define conditions prevailing before the start of recharge operations.

"This report was prepared in fulfillment of the U.S. Atomic Energy Commission Contract No. AT(05-1)-1623 to the University of North Carolina during the Period May 1973 through September 1981."

Results of reconnaissance surveys of the Williamsport quadrangle to determine the likelihood of uranium deposits of the area, and additional information about the location and classification of any deposits.

From introduction: The purpose of the study was to assemble data on the occurrence, movement, availability and chemical quality of ground water in the Hackensack River basin in Bergen and Hudson Counties, New Jersey; to evaluate and interpret the data; and to make the results available to the public.

From introduction: Geochemical studies of zinc-bearing peats in western New York State show them to be related genetically to underlying mineralized beds of the Lockport dolomite of Niagaran age. (...) Intermittent field work was begun in the area by the United States Geological Survey in September 1946; after some interruptions, field work was completed in June 1948. In 1950, 1,900 feet of diamond drilling was completed in the area.

Purpose and scope: This report presents results from an evaluation of geologic data collected and compiled as part of a continuing investigation and appraisal of hydrologic conditions in Suffolk County. The investigation is part of a cooperative program of water-resources studies made by the U.S. Geological Survey in cooperation with the Suffolk County Water Authority and the Suffolk County Department of Health Services.

Discussing the evaluation made of the Scranton Quadrangle for environments favorable for uranium

This report summarizes and interprets the data dro about 500 stream sediment samples, 500 stream water samples, and 500 ground water samples, each analyzed for 40 to 50 elements.

Report discussing earthquake activity in the United States during 1944. The report is broken down by regions and has sections for specific earthquakes.

This report presents the analysis of "data from three two-day aquifer tests of the unconfined aquifer (water-table_ aquifer in southern Nassau Count, Long Island, during the autumn of 1979.

Preface: In 1948, the U.S. Geological Survey, in cooperation with the Atomic Energy Commission, initiated a study of the hydraulics and hydrology of Mohawk River in the vicinity of the Knolls Atomic Power Laboratory (KAPL) near Schenectady, N.Y. The purpose of this study was to determine the probable effects of release of low concentrations of radioactive wastes from the Laboratory to Mohawk River.

Abstract: Unconsolidated strata of clay, silt, sand, and gravel of Late Cretaceous and pre-Wisconsin Pleistoscene ages lie between crystalline basement rocks (bedrock) of Precambrian (?) age and unconsolidated deposits of late Pleistocene (Wisconsin) and Holocene ages in Queens County, Long Island, N.Y., a borough of New York City. Data collected during a recent study of the hydrogeology of the county and updated records of earlier studies have been used to prepare contour maps that delineate the surfaces of the bedrock and the Upper Cretaceous and pre-Wisconsin Pleistocene deposits. The presence of diabase fragments, apparently from the Hudson Palisades, in a buried valley through the county suggests that the ancestral Hudson River was diverted into Queens County in Pleistocene.

This report appraises water resources in Homer-Preble valley in central New York and judges that despite an expected rise in residential development, the glacial-outwash aquifer can still operate as the site's main source of water without seriously reduce water quality or quantity. It contains maps, graphs, and tables.

A paper pertaining to the trap dikes of the region around Lake Champlain.

This report presents the results of ground water, stream water, and stream sediment reconnaissance in Pennsylvania, New Jersey, and New York.

From abstract: This report studies the covers over radioactive waste burial trenches in New York; it describes the results of "measurements of atmospheric pressure and the differential pressure between the trench gas and the atmosphere" over a two year period. It contains maps, graphs, and tables.

Outline of Problem: "This paper covers a survey of 19 ores collected from seven of the more important iron-ore districts of the United States and is a contribution by the ore-dressing section of the United States Bureau of Mines to general research program on iron and steel being conducted by the Bureau."

"This report is the last in a series by the New York State Geological Survey on studies funded by the U.S. Nuclear Regulatory Commission. The report covers five important aspects of the geology and hydrology of the Western New York Nuclear Service Center, near West Valley, New York: geomorphology, stratigraphy, sedimentology, surface water, and radionuclide analyses. We reviewed past research on these subjects and present new data obtained in the final phase of NYSGS research at the site. Also presented are up-to-date summaries of the present knowledge of geomorphology and stratigraphy."
