Summary

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/
