Authorities Take Over Monitoring Of Contamination At Maquoketa

Federal monitors are assuming control of efforts to keep tabs on the contamination from a cancer-causing chemical at a former factory site in Maquoketa.  The chemical has been traced back to the operations of Clinton Machine County, which built small engines for four decades ending in the 1990s.  The factory used a degreasing agent known as T-C-E.  Scientists say if T-C-E is in the groundwater, it creates the potential for indoor contamination as well.
