The latest demand from the Illinois Environmental Protection Agency will require Colchester to cap the wells that used to provide the city's drinking water. Since 2005 the city has been buying its water from Macomb.
Mayor Danny Bice said the five wells are in Troublesome Bottom.
He said, “Those wells are just sitting there, you know. We're not ever going to fire them back up. So the EPA came in two weeks ago and did an investigation and we've got to cap them permanent to be in compliance.”
