DEQ will take additional enforcement action against Chemours for unreported spill Water sampling indicates wastewater spill at Chemours facility

Raleigh

RALEIGH – The N.C. Department of Environmental Quality will take additional enforcement action against Chemours for an increase in the concentration of GenX in the wastewater discharge at Chemours’ Fayetteville Works facility identified in recent water quality sampling results.   

DEQ questioned Chemours officials after receiving preliminary data from the Environmental Protection Agency indicating elevated concentrations of GenX at Chemours’ primary wastewater discharge outfall.   

In response, the company told DEQ that a spill had occurred Oct. 6 from a manufacturing line at the Chemours facility. The company indicated to state officials that dimer acid fluoride, a precursor to GenX, had spilled during planned maintenance at the facility.  

“We are determining all appropriate enforcement actions based on violations that have been committed, and we will continue to investigate and hold the company accountable,” said Sheila Holman, assistant secretary for the N.C. Department of Environmental Quality.    

At DEQ’s request, Chemours officials provided the company’s own preliminary test results from water samples collected at the Chemours outfall around the time of the spill. The data show concentrations of GenX at Chemours' wastewater discharge outfall increasing to 250 parts per trillion on Oct. 6, and peaking at 3,700 parts per trillion on Oct. 9. The concentration at the outfall then dropped to 740 parts per trillion on Oct. 12, and 380 parts per trillion on Oct. 16. Prior to the spill, water samples collected between Oct. 2 and Oct. 5 show concentrations of GenX at Chemours’ wastewater discharge outfall between 35 and 69 parts per trillion.
