In the statement, the city says the material was dumped into pipes that feed into Sugar Creek Wastewater Treatment Plant off Tyvola Road. Charlotte-Mecklenburg Police have shut down the Sugar Creek plant's operation. Flow is being diverted to an isolated containment basin on the plant site.
"They will be housed out of our arson investigation unit."Monroe said."They will be a full time unit over the coming weeks to try to identify how this occurred."
City Manager Ron Carlee said anyone, human or animal, should avoid contact with water from Mallard Creek and the Rocky River in Cabarrus County until more testing can be done.
PCBs were banned by the government in the 1970s.
In light of the discovery of the second illegal dumping, people are also asked to avoid Sugar Creek.
Carlee says the dumping does not affect the city's water supply and drinking water.
Charlotte-Mecklenburg police are investigating this as a criminal case and say the person responsible will likely face state and federal charges.
Anyone with information about the case is asked to call Crimestoppers at 704-334-1600.
