CFPUA Chairman’s Afternoon Update: July 20, 2017

Mike Brown, CFPUA Board chairman, will provide two daily updates—one morning and one afternoon—with information on activity surrounding GenX. Updates will be provided each weekday. Below please find Chairman Mike Brown’s afternoon update on a CFPUA call with NC DHHS today, GenX test results from the Sweeney plant and the Richardson plant, and Governor Coopers’ Wilmington visit on Monday.


1. CFPUA staff had a call with NC DHHS this afternoon to discuss water samples from earlier this month (July 7, July 10, and July 12). DHHS reinforced that, when measuring at levels this small, variation is to be expected. With the July 10th level being only 5 ppt above the standard, it is within that realm of variation. DHHS stated that they still believe the water is safe to drink, and provided the following statement:

  • “NC DHHS does not recommend any additional steps based on these results, including the finished water result of 145 ppt from July 10. We are discussing very small concentrations, measured in parts per trillion, so some variability in laboratory results is expected. The results we’ve seen so far have been trending down and have not been substantially different from the health goal, which is set at the most conservative level.”

NC DEQ Assistant Secretary Sheila Holman confirmed that Chemours stopped the additional source of GenX discharge the week of July 9. With the time it takes the river to reach us, the July 10 CFPUA sampling would have included that additional discharge. 

  • The test results discussed with DHHS today were received yesterday afternoon and released last night. The water samples results are as follows:
  • July 7: 132 ppt
  • July 10: 145 ppt
  • July 12: 122 ppt

In keeping with NC DHHS’ advisory – which is the only measure CFPUA is able to operate under at this time—we reported that the July 10th sample is above the acceptable ppt level.

It is important to make clear, however, the July 10th sample was taken during a time period, as indicated above, when it is now known that GenX was being discharged by Chemours into the Cape Fear River.

We remain committed to being open and transparent to the public on this important matter. For that reason, we are reporting this finding. 

Within two days, GenX concentrations were back below the recommended 140 ppt. As an added measure of caution, CFPUA has ordered that independent testing by Eurofins be increased from three random samples per week to daily sample testing. We will share more results with the public on future sample tests as soon as they are available.

CFPUA remains committed to providing the highest quality drinking water for our customers. We will continue to prioritize communication and transparency as we seek additional information.


2. These Sweeney plant test results have been posted to the website. 


3. See the full testing timeline and read CFPUA’s statement on these test results.


4. On July 13, CFPUA sampled water at the Richardson Nanofiltration Plant—which serves the free water station at Ogden Park—for GenX. GenX was not detected. This water is supplied by underground aquifers that have not been affected by Chemours’ discharge of GenX. Residential CFPUA customers may fill their clean personal containers at New Hanover County’s Ogden Park near the tennis courts at 615 Ogden Park Drive. This is available daily from 8 am to 8 pm.

  • The Richardson plant test results have been posted to the website. 

5. A Governor Cooper spokesperson confirmed late yesterday that he will be in Wilmington on Monday to meet with local officials to talk about the State’s next steps to address GenX in the Cape Fear River. We will share additional information as it is available.


6. CFPUA encourages the public to check our website and social media channels for updates as this continues to unfold. We are committed to transparency, and we look forward to continuing our partnership with you through the duration of this process.
