General Information:

The Safe Drinking Water Act gives the U.S. EPA 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 within the designated area to ensure they will not contaminate the aquifer.

The Mahomet Aquifer system is an underground layer of water-bearing sand and gravel that fills a wide bedrock valley in all or parts of 14 east-central Illinois counties. The aquifer system is the source of approximately 53 million gallons of water every year for 120 public water systems and thousands of rural wells that serve about a half million people. More than half of the population in east-central Illinois relies on the Mahomet Aquifer system as a source of their drinking water.
