This data set represents the extent of the New York and New England carbonate-rock aquifers in the states of New York, Vermont, Maine, Massachusetts, Connecticut, New Jersey, and Pennsylvania.

This dataset contains the well location, construction information, and water-level measurements for 983 wells measured during a groundwater-level synoptic of 10 confined aquifers of the New Jersey coastal plain and water-level measurements for 5 wells in 2 confined aquifers of the Delaware coastal plain. Groundwater-level measurements were made from October 2013 to January 2014. Well-location and water-level data is publicly available from the U.S. Geological Survey's National Water Information System (NWIS). Groundwater-level measurements were used to construct the potentiometric surface contours of the confined Cohansey, RioGrande, Atlantic City 800-ft Sand, Piney Point, Vincentown, Wenonah-Mount Laurel, Englishtown, and Upper, Middle and Lower Potomac-Raritan-Magothy aquifers.

This point shapefile consists of digital points that represent water level altitudes in the Lloyd and North Shore aquifers of Long Island, New York. The U.S. Geological Survey measured 55 observation wells and 5 supply wells screened in the Lloyd aquifer and the contiguous and hydraulically connected North Shore aquifer. This point shapefile is a digital representation of the water levels presented in sheet 3 of Scientific Investigations Map 3398.

From 2013 to 2018, the U.S. Geological Survey, in cooperation with the Town of Enfield and the Tompkins County Planning Department, studied the unconsolidated aquifers in the Enfield Creek Valley in the town of Enfield, Tompkins County, New York. The objective of this study was to characterize the hydrogeology and water quality of the unconsolidated aquifers in the Enfield Creek valley and produce a summary report of the findings. The spatial extent and hydrogeologic framework of these unconsolidated aquifers were delineated using existing data, including soils maps, well records, geologic logs, topographic data, and published reports. An interactive ArcGIS Online web map of the geospatial datasets is available here: https://usgs.maps.arcgis.com/home/webmap/viewer.html?webmap=b53518b0b6b74694932605c4578c00c3. These geospatial datasets support U.S. Geological Survey Scientific Investigations Report 2019-5136, "Geohydrology and Water Quality of the Unconsolidated Aquifers in the Enfield Creek Valley, Town of Enfield, Tompkins County, New York."

In 2011, the U.S. Geological Survey, in cooperation with the Town of Newfield and the Tompkins County Planning Department, began a study of the stratified-drift aquifers in the West Branch Cayuga Inlet and Fish Kill valleys in the Town of Newfield, Tompkins County, New York. The objective of this study was to characterize the hydrogeology and water quality of the stratified-drift aquifers in the West Branch Cayuga Inlet and Fish Kill valleys and produce a summary report of the findings. This dataset contains locations of drainage divides in West Branch Cayuga Inlet and Fish Kill Valleys, Newfield, Tompkins County, New York.
