The City of Hannibal and the Hannibal Board of Public Works asks for a change of venue in a class-action lawsuit.

The Courier-Post reports the city and BPW filed the motion in the 10th Judicial Circuit Tuesday.

The suit alleges that BPW did not provide potable water to customers from September of 2011 to September of 2015, exposing them to “probable human carcinogens.”

The suit, filed by four Hannibal residents, asks for unspecified damages from the consumption of water that exceeded federal mandates for disinfection byproducts.

The suit does not say specifically say that the water made anyone sick during that four year period.
