Notification to Private Water Well Users

From Groundwater Contamination in Community Water System Wells

The 2002 Right-to-Know law requires the Illinois Environmental Protection Agency (Illinois EPA) to notify the Illinois Department of Public Health (IDPH) and the unit of local government affected when any volatile organic compound is detected in a Community Water System (CWS) at a concentration above the Class I groundwater quality standard. 

IDPH is then required to notify private water well users within the area potentially affected by the identified contamination.

Public notices are issued by means of electronic or print media to inform private water well users of the contamination and the need for water testing. The public notice must appear in the media for three consecutive weeks.
