EPA Seeks Comments on Proposed Sole Source Aquifer Designation

EPA has announced a proposed decision to approve a petition asking that the Mahomet Aquifer System in east-central Illinois be designated as a sole source aquifer. The Safe Drinking Water Act gives EPA the authority to designate an aquifer as a sole or principal source of drinking water for a specified area. That designation allows EPA to review all federally funded projects in the area to ensure they will not contaminate the aquifer.

June 2014 Update

The public comment period for the Proposed Mahomet Sole Source Aquifer Designation closed on June 12, 2014. EPA is currently reviewing information received. At the conclusion of this review, EPA will announce its decision regarding designation on this website, through a press release, and in the Federal Register. Thank you for your interest and participation.
