This week, CFPUA will be integrating new types of Granular Activated Carbon and Ion Exchange media into the pilot test to measure their potential in removing PFAS. Additionally, testing will be conducted with longer periods of contact time to measure the effectiveness of various bed depths in removing these compounds from the water.
As reported earlier this month, the ongoing pilot test at Sweeney Water Treatment Plant has recorded breakthrough of GenX and other PFAS in the Granular Activated Carbon and Ion Exchange media. Compound breakthrough is inevitable in all media, and no media will be able to filter 100 percent of the compounds out of the water. The goal of the pilot test is to measure and compare breakthrough rates between different media brands and technologies—a strategy that will allow CFPUA to find the most effective design at the best cost for ratepayers.
CFPUA will continue to publish monthly updates on the pilot test at Sweeney as the program progresses. For data from the pilot test, see our Special Compound Testing page.
CFPUA employees often travel throughout Wilmington and New Hanover County to conduct water sampling, infrastructure improvements and other routine maintenance work on the system.
However, CFPUA employees would not need to enter a home to test water unless it is scheduled in advance with the customer. Furthermore, all CFPUA staff carry company-issued photo identification cards that can confirm their employment with the organization.
If you have questions about whether a person represents CFPUA, call 332-6625 during business hours to verify their status and to confirm if CFPUA is working in your area.
We have received the results for November 21 from our on-going GenX testing at the Sweeney Water Treatment Plant. Levels of GenX continue to remain below the DHHS health goal of 140 ppt.
