Many homes in the area use water from Rockton Village, but anyone who is using a private well should not eat it, officials said.
The Winnebago County Health Department said it was “not necessarily” related to the Chemtool fire because the source of the contamination was unknown.
The mid-June event caused a devastating explosion over rural Northern Illinois, sending a fireball into the sky. Large flames from the chemical plant caused heavy smoke to cover the air with a huge plume that could be seen from roughly 40 miles away.
About 40 to 45 agencies from northern Illinois and southern Wisconsin responded to the blaze that burned for days. It is estimated that there are about 1,000 residents evacuate the area around the Chemtool factory near Rockton after the June 14 fire, which authorities say was started accidentally. The company manufactures lubricants, greases and other fluids.
