The Wisconsin Department of Natural Resources (WDNR) provided funding for this
project through the Groundwater Management Practice monitoring Program which
receives appropriations from the Groundwater account.


A multitude of groundwater quality data, spill, and waste disposal practice information
exists within WDNR. Since this information is in segregated hard copy files, it is
relatively unretrievable by individuals outside the program of interest. This project
addresses that massive information management problem with the design of a
geographic information system for groundwater associated data in Lake Michigan
District WDNR. The Lake Michigan District (LMD) is situated in northeast Wisconsin
and consists of the following counties: Florence, Marinette, Oconto, Menominee,
Shawano, Waushara, Waupaca, Outagamie, Brown, Door, Kewaunee, Manitowoc,
Calumet and Winnebago.

Lake Michigan District WDNR has produced quality digitized groundwater information
with a 36" X 48" digitizing table, 36" plotter, and 486 computer work station with PC
ARC/INFO GIS software located in the office. This project has required the
examination of numerous spill and groundwater quality monitoring files. Information
retrieval was rather protracted since, generally, no single file contains all the District's
groundwater information. As part of this project much of the WDNR Lake Michigan
District spill and groundwater contamination information has been assembled into a
relatively updated paper file also. These various updated information layers have
been digitized to produce quality district-wide maps, which are variable by user
