"CHARLOTTE, N.C. — The city of Charlotte is still trying to recover from one of the worst catastrophes in the city's history.
 
Someone illegally dumped a dangerous chemical that reached plants that treat the water hundreds of thousands of people use.
 
While police continue to look for a suspect, it's costing Charlotte millions of dollars to clear it out.
 
The cancer-causing chemical, polychlorinated biphenyl or PCB, was illegally dumped in a grease trap behind a Food Lion on West Sugar Creek Road flowing to the creek in to Mallard Creek Wastewater Treatment Plant."
