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 zipfile contains an ESRI "shapefile." 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.
