CHICAGO — The U.S. Environmental Protection Agency Region 5 is proposing to designate the Michindoh aquifer as the sole source of drinking water for an area comprising eight counties.

The area include parts of Allen, DeKalb and Steuben counties in Indiana; Hillsdale and Lenawee counties in Michigan; and Defiance and Fulton counties and all of Williams County in Ohio.

A map shows that the aquifer area includes Ashley, Hudson, Hamilton, Butler, St. Joe and Spencerville, as well as much of eastern DeKalb and Steuben counties. The map may be viewed at

The designation will provide greater protection for the aquifer. The proposal is open for public comments until Friday, Nov. 6. If no significant comments are provided, the decision will become final.

When an aquifer is designated the sole or principal source of drinking water for an area, EPA must review all federally funded projects in the area to determine their potential for contaminating the aquifer. No federal funds may be spent on projects that EPA determines may contaminate the aquifer.

A copy of the Michindoh Sole Source Aquifer Petition is available for review at EPA’s regional office in Chicago, 77 W. Jackson Blvd., and at the Bryan, Ohio, Municipal Utilities Office, 841 East Edgerton St.

More information is available on EPA’s Web site: and at

Comments or questions about the decision mat be sent to William Spaulding, WG-15J, U.S. EPA Region 5, 77 W. Jackson Blvd., Chicago, IL 60604, or e-mailed to
