More potentially cancer-causing chemicals have been found in local grease pits that hook into sewer systems around the Upstate.State regulators say trace amounts of PCBs were found in the grease pits behind Bi-Lo grocery stores on Reidville Road in Spartanburg and Wade Hampton Boulevard in Greer.
PCBs is a contaminant that was banned by the US Congress in the 1970S.
Earlier this summer PCBs were discovered in three water systems during its annual testing. Spartanburg Sanitary Sewer District, ReWa in Greenville and Lyman Water all found PCBs.
The investigation since then has shown the chemicals made it into the sewer system through someone illegally dumping waste into grease pits behind grocery stores and restaurants.
S.C. health regulators issued a cease and desist order to American Waste Septic Tank waste service in Greer a couple of weeks ago, and accused the company of having PCBs on its equipment.
The owner of the company has told WSPA he has no idea how the chemicals ended up on his equipment.
Sue Schneider, the director of SSSD, says since just trace amounts of PCBs were discovered in the waste water system there is no public health threat. However, it'll cost millions to clean up, she said.
