Web-Delivered Application for Hydrogeologic Data

Project Contact(s)

This project is designed to deliver, by web-based technologies, the most commonly available and requested geologic and hydrologic information used in hydrologic studies required by regulation and ordinance and used by state agencies to support resource-management decisions. Available information can be associated with points or areas. Information associated with points includes descriptive logs, geophysical logs, raw and interpreted groundwater levels, aquifer and geologic unit identification, and hydraulic characteristics of wells. Information associated with areas is either in the form of raster-based (grid) data or polygons. Examples of raster-based data include water-table depths and elevations, tops and thicknesses of geologic and aquifer units, and aquifer transmissivity. Examples of polygons include surficial geology and groundwater recharge potential.

The intent of developing a web-technology enabled system is to provide a more intuitive and comprehensive toolset for locating, quickly viewing, and downloading the desired information in an efficient, extensible, and familiar manner.

DGS First Drill Rig

President of the University Of Delaware, John A. Perkins, who was an ex-officio member of the Geological Commission, requested Henry B. Du Pont to donate a small truck mounted auger drilling rig to the University for use of the Delaware Geological Survey. With wishes granted, the rig was put into operation in 1951.
