Description: The Ohio Department of Natural Resources, Division of Geological Survey, with partial funding from the USEPA through the Ohio EPA, has mapped the lowest Underground Sources of Drinking Water (USDWs) across most of the state. The goal of this project is to provide Ohio's oil and gas industry and the Ohio Department of Natural Resources-Division of Oil and Gas Resources Management (DOGRM) with necessary, up-to-date information and maps to properly determine adequate depth of surface casing to protect USDWs. The last mapping effort of the lowest USDW was performed in 1982. In excess of 37,000 oil and gas wells have been drilled since that date without significant updates to the mapping. Further, the 1982 mapping was hand-drawn on paper maps, which are not easily reproducible or updated. Existing water-quality data have been collected and correlated to bedrock geology. The resultant data are being used to produce structure contour maps on the base of the lowest mappable, consolidated (i.e., bedrock) unit designated as a USDW. Surface casing is always required through unconsolidated surficial deposits, whose depths are known from other mapping projects. All information has been compiled and mapped digitally for ease of distribution and future updating. Industry will be able to use these maps and data to correctly estimate the length and cost of casing required for each well prior to submitting a permit application. The DOGRM will be able to directly import the data and maps to their computer applications and use it to establish required casing depths on permit applications.

Display Field: Shape_Length

Type: Feature Layer

Geometry Type: esriGeometryPolygon

Description: This data layer contains the Devonian outcrop polygons for Ohio. The polygons were originally derived from the 1:24,000-scale bedrock-geology maps, that were created between 1989 through 1998. The bedrock-geology mapping program was initiated in the mid-1980s to perform detailed, 1:24,000-scale bedrock-geology maps. In 1991, the mapping approach was amended to a reconnaissance mapping methodology, but retaining the 1:24,000 scale. Both detail and reconnaissance bedrock-geologic maps were used as the basic information to compile the 1:500,000-scale, Bedrock Geologic Map of Ohio. The Devonian outcrop polygons were then extracted from the 1:500,000-scale, Bedrock Geologic Map of Ohio.

Service Item Id: 9f1ef57612c0480a8fe3f1f67eaea2cf

Copyright Text: Production of the 7.5-minute, reconnaissance and detailed, bedrock-geology maps was facilitated by funding provided by the Ohio minerals severance tax and grants from the U.S. Geological Survey COGEOMAP Program and STATEMAP component of the National Cooperative Geologic Mapping Program, the Ohio Department of Transportation, and the Ohio Environmental Protection Agency under provisions of Section 319(h) of the Clean Water Act as amended in 1987. Completion of this map and the bedrock mapping program were facilitated by significant contributions by H. R. Collins, D. N. Hull, T. M. Berg, R. L. Stewart, J. McDonald, K. Callahan, E. V. Kuehnle, J. A. Kriz, R. T. Link, D. A. Stith, C. S. Brockman, K. E. Vorbau, R. R. Pavey, M. T. Baranoski, R. W. Carlton, L. Van Doren, and R. O. Klingbeil. Cross section digitization by J. L. Fox. Reconnaissance mapping consultations provided by C. H. Summerson, J. T. Dutro, and W. D. Martin, who kindly contributed data also on the Dunkard Group in Athens and Washington Counties. S. M. Bergström, G. K. Merrill, B. M. Blake, L. E. Babcock, and M. A. Kleffner graciously assisted with geologic age refinement.
