This data set contains subsurface information compiled from hardcopy and digital public data available at Ohio Division of Geological Survey, Ohio Division of Oil and Gas Resource Management, Class-one industrial waste sites and out of state agencies. The data in the dataset come from a number of different sources, which include hardcopy reports, well completion cards, core and sample descriptions, core and sample examination, open-hole geophysical well log analyses, and seismic reflection data. Location information is plotted in Ohio State Plane south zone coordinates from map coordinates digitized from well locations on hardcopy township well-spot maps which have been digitally corrected for political subdivision boundaries. Locations may not match reported State Plane coordinates from well completion information and most likely do not represent exact physical locations of boreholes either surface or at total depth.<\/SPAN><\/P>

This data set was created as part of a project to update and revise the Structure contour map on the Precambrian unconformity surface in Ohio and related basement features (Baranoski, 2002). Contours in Baranoski (2002) were originally hand digitized using Intergraph software and hardware. Contours, well data, faults, tables and drawings were and subsequently imported into ArcGIS shapefiles and reformatted The ArcGIS shapefiles were exported to be compiled with report and data tables as a pdf file. Data shows the location of Class-1 industrial waste disposal sites, brine disposal sites, locations with Precambrian paleotopographic erosional high areas, and locations drilled below into or proximal to the Precambrian unconformity surface and surrounding region. The revised version (Baranoski, 2013) was updated using Geographix software by adding well locations and digitally hand contouring. Updated maps and well data were exported as UTM Zone 17 84W-78W Longitude NAD 83 decimal degrees shape files from Geographix into Microsoft Excel and ARC. Microsoft Excel well data was imported into ArcGIS during final map finishing and into Adobe InDesign for report tables. The final report, map, and tables were compiled into a pdf file using Adobe InDesign.<\/SPAN><\/P>

This work was supported, in part, by funding from the Injection Well Review Fund and was performed in cooperation with the Ohio Environmental Protection Agency, Division of Drinking and Ground Waters. Richard Ostrowski with the Ontario Oil, Gas & Salt Resources Library in London, Ontario, provided additional Ontario data.<\/SPAN><\/P>

The following staff from the Ohio Geological Survey worked on this shapefile: Mark Baranoski was the author. Michael Solis reviewed an early revised version of the map. Dean Martin formatted the digital map data and set up the map layout. Lisa Van Doren updated tables and formatted the map into the final PDF file. Chuck Salmons edited final copy. Joseph Wells edited some of the digital data. Robert Hanover wrote the metadata.<\/SPAN><\/P>
