Sole Source Aquifer Designation of the Mahomet Aquifer System in East-Central Illinois

Notice is hereby given that pursuant to the Safe Drinking Water Act (SDWA) Section 1424(e) and in response to a petition by a coalition of cities, a town, villages, and a public university in east- central Illinois, the Regional Administrator for Region 5 of the Environmental Protection Agency (EPA) has determined that a portion of the Mahomet Aquifer System in east-central Illinois is a sole or principal source of drinking water and if contaminated, would create a significant hazard to public health. As a result of this action, all projects receiving Federal financial assistance are subject to review by EPA regarding whether such projects may contaminate the designated aquifer system through a recharge zone so as to create a significant hazard to public health.
