FAQ Regarding Emerging Compounds and GenX

Is our drinking water safe? 

We take water quality very seriously, and with our advanced treatment processes we continue to meet all state and federal drinking water standards for safety. Since the State of North Carolina and EPA establish the drinking water standards we comply with, we will be looking to them to determine whether this currently unregulated contaminant should be regulated at the point of discharge to the Cape Fear River.

What do we know about GenX?

We know that it is unregulated and measured in the parts per trillion. At this time, data is not readily available on whether this is a compound of concern. Ultimately, EPA will determine potential impacts and safety standards.

What can be done at the treatment plant to remove GenX from the water?

GenX is an emerging contaminant, and we are unaware of technologies capable of removing this compound from the water. Thus, the more important issue is for the State of North Carolina and EPA to keep this compound from being discharged into the river.

With GenX in the Cape Fear River, what can/will CFPUA do to ensure the water is safe?

CFPUA treats its source water above and beyond current state and federal standards, and maintains a robust sampling and monitoring schedule. Additionally, we believe in the importance of participating in studies such as this one to ensure that emerging compounds are discovered and appropriately regulated to protect drinking water utilities and their customers. CFPUA believes the best next step is to determine if this compound needs to be regulated and, if so, ensure that enforcement methods keep it from entering the Cape Fear River.

Does CFPUA monitor for GenX? If not, why?

Due to GenX’s status as an emerging and unregulated contaminant, there are no EPA-certified methods to monitor and test for the substance. For more information on permitting and compliance enforcement, please contact the State of North Carolina Division of Environmental Quality—the agency responsible for monitoring and regulating dischargers on the River.


If CFPUA participated in the study and knew the results, why did you not release them earlier?

After becoming aware of the study’s findings, CFPUA staff initiated, and maintained, conversations with the researchers associated with the study to learn more about the compound and the available testing options. Additionally, CFPUA contacted the State of North Carolina, the agency responsible for regulating Chemours’ discharge into the Cape Fear River, to inform them of the findings.

Can customers put a filter on their tap to remove GenX?

GenX is a new, unregulated compound and we are unaware of technologies capable of removing it from the water.
