Hydrogeologic correlations for selected wells on Long Island, New York — A data base with retrieval program
Accurate delineation of the internal hydrogeologic structure of Long Island, NY is integral to the understanding and management of the groundwater system. This report presents a computerized data base of hydrogeologic correlations for 3,146 wells on Long Island and adjacent parts of New York City. The data base includes the well identification number, the latitude-longitude of the well location, the altitude of land surface at the well and of the bottom of the drilled hole, and the altitude of the top of the major hydrogeologic units penetrated by the well. A computer program is included that allows retrieval of selected types of data for all of, or any local area of, Long Island. These data retrievals are a valuable aid to the construction of hydrogeologic surface maps.

Geohydrology of the Bethpage-Hicksville-Levittown area, Long Island, New York
A study of ground-water levels and flow in east-central Nassau County, N.Y. , began in October 1985. The 11.4 sqare-mile area encompasses parts of Bethpage, Hicksville, Levittown, Plainview, Plainedge, and Farmingdale. Approximately 1,200 ft of unconsolidated Cretaceous deposits and 50 to 100 ft of Pleistocene deposits overlie bedrock throughout the area. The unconsolidated deposits consist mostly of sand, gravel, silt, and clay and have good water-transmitting properties except where clay forms continuous layers that can impede groundwater flow. The area is mostly residential and industrial. Pumpage for public supply exceeds 10 million gallons per day, most of which eventually discharges from the ground-water system to tidewater as sewage outflow. Industrial pumpage during summer exceeds 10 million gallons per day, but most of the water is returned to the system through recharge basins. Ground-water levels in this area fluctuate seasonally in response to natural recharge, pumping, and use of recharge basins.

Potentiometric surfaces on Long Island, New York -- A bibliography of maps
Historic water-level records form a major basis for ground-water investigations and water-management decisions on Long Island. Potentiometric-surface maps, one of the major sources of historic data, are scattered within the literature or are available only through the publisher or sponsoring agency. This report presents a comprehensive list of available water-table and potentiometric-surface maps from the 19th century through 1979 with the scale, years represented, and area depicted; complete bibliographic citations are included to facilitate retrieval. The bibliography is preceded by a summary of the hydrologic system and a short history of ground-water development on Long Island, with emphasis on the effects of urbanization as reflected in ground-water levels. A series of six water-table maps from before 1900 through 1979 is presented to illustrate the major historic ground-water trends. (USGS)
