This child item dataset contains 22,871 records of chloride concentration in groundwater across Kings, Queens, and Nassau Counties in Long Island, New York. Compiled records span the period from 1889 to 2022. Records are provided in a shapefile of point data compiled from several sources detailed in the metadata. Chloride isolines (isochlors) are also included as a shapefile of interpolated point data representing average conditions over 11 twenty-year time periods in the two main Long Island aquifer complexes (Upper glacial-Jameco-Magothy and North Shore-Lloyd). Interpolation methods are discussed in Stumm and others (2024). These data are accessible as an online webmap: https://ny.water.usgs.gov/maps/lisustainabilityphase1viewer/

This child item dataset contains shapefiles and rasters defining the hydrogeologic framework of Kings, Queens, and Nassau Counties, New York. These data were derived from 643 lithologic and (or) geophysical logs, defining 1,715 contacts between different aquifers and confining units across western Long Island. Extents, contour elevation lines and interpolated surfaces were created for each of the framework units. These data are accessible as an online webmap: https://ny.water.usgs.gov/maps/lisustainabilityphase1viewer/
