EPA Considering Application for Sole-source Aquifer Status
EPA is evaluating an application from the city of Bryan, Ohio, to designate the Michindoh Aquifer as a "sole-source" aquifer. That designation means the aquifer is the only source of drinking water for people in a nine-county area that includes parts of three states. The following documents provide information on this consideration.

This shapefile is a Geographic Information System (GIS) file type consisting of numerous associated files which work together when loaded by desktop GIS software. These files have been bundled into one downloadable file using the "ZIP" compression format. After downloading the zip file, the bundle will need to be "unzipped" with an "unzip" utility. Unzip utilities are available separately from EPA and may be found via a search engine. EPA does not endorse one or any particular unzip utility.

Michindoh Aquifer Sole Source Aquifer Petition Update (March 2013)
Based on comments received in April 2010, a scoping study was conducted to assess available geologic information which would support a designation determination. Based on the study findings, EPA requested further information from the City of Bryan, Ohio, the author of this sole source aquifer designation petition. Until this information is received, EPA has determined that sole source aquifer designation for this petition is indefintely suspended.
