New Jersey Department of Environmental Protection (NJDEP), New Jersey Geological Survey (NJGS)The Surficial Aquifers of New Jersey consists of Geographic Information Systems (GIS) shape file of the surficial aquifers and confining units in New Jersey. The surfical-aquifer coverage includes glacial sediment exceeding 50 ft. thickness in northern New Jersey, and surficial sediment thicker than 50 ft. overlying Coastal Plain aquifers and confining units. The coverage is generalized to the 1:250,000 scale by eliminating polygons with less than 1,000,000 sq. ft. area (about 23 acres). The data were digitized from various published and unpublished 1:24,000, 1:100,000, and 1:250,000 scale geologic maps compiled from 1987 to 1993.ArcGIS DynamicMapLayerhttps://hub.arcgis.com/datasets/9250ed8bba2f43f4ae9edc58c47c3080_23engNew Jersey Department of Environmental Protection's (NJDEP) Bureau of GISPublicSurficial Aquifers in New Jersey [New Jersey]Web servicesNew JerseyLast Modified: 2023-12-27
