New Jersey Department of Environmental Protection, New Jersey Geological SurveyThe Bedrock Aquifers of New Jersey consists of Geographic Information Systems (GIS) shape files of the bedrock aquifers and confining units in New Jersey. The bedrock-aquifer coverage includes fractured-rock aquifers of the Valley and Ridge, Highlands, and Piedmont physiographic provinces, and aquifers and confining units of the Coastal Plain physiographic province. The coverage was 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 The data were digitized from various published and unpublished 1:24,000, 1:100,000, and 1:250,000 scale geologic maps compiled from 1987 to 1993.ArcGIS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/e97e2c43e4724379a7e650fb8de37996_13engNew Jersey Department of Environmental Protection's (NJDEP) Bureau of GISPublicBedrock Aquifers in New Jersey [New Jersey]Web servicesNew JerseyLast Modified: 2023-12-27
