Illegally dumped polychlorinated biphenyls (PCBs) found in North Carolina’s sewer system in February 2014 will cost the City of Charlotte more than $1.3 million to remediate.
The City’s utilities department traced the PCBS from the Mallard Creek treatment plant in early February 2014. The toxic chemicals were also found in sludge at the McAlpine Creek plant.
CMUD suspects the dumping was by someone who wanted to avoid the expense of legally disposing of the chemicals. Authorities offered a $10,000 reward for information.
Charlotte City Council has approved vendor contracts of $970,000 for testing, waste handling and decontamination of the PCBs, plus another $317,000 to buy new lab equipment and supplies to expand PCB testing.
PCBs were detected in four South Carolina treatment systems, beginning in July. None have been found in North Carolina cities other than Charlotte.
