In 2007, the city of Bryan, Ohio applied to U.S. EPA 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.
March 2013 Update - 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.
