Sauk Village Water Supply Contamination Issue

Sauk Village

In June 2009, Illinois EPA mailed public notices to all Sauk Village Water Supply users regarding vinyl chloride contamination in groundwater that is affecting the community water supply. In the water drawn from Well Number 3, the concentration of vinyl chloride in 2009 [at 3.49 micrograms per liter (ug/L)] violated the federal maximum contaminant level of 2 ug/L allowed for a public water supply. Well Number 3 was taken out of service in 2009 and has not been part of the system since then because of the vinyl chloride contamination.
