In early August, after testing showed the presence of GenX in the Aquifer Storage and Recovery well, CFPUA decided to remove 50 million gallons of water containing the chemical from the aquifer. Staff pumped water out of the well at a rate of 500 gallons per minute, and the project took just over two months to complete.
The goal of the project was to remove water from the aquifer containing GenX, and to investigate how its removal would impact both the aquifer itself and levels of detectable GenX. Staff, along with officials from NCDEQ, will now investigate the aquifer’s reaction to the pumping and decide the best course forward.
We will continue to update the public as this project progresses.
CFPUA Director of Engineering, Carel Vandermeyden, has been asked to serve as a member of the Technical Advisory Committee for the Water Research Foundation’s new focus area: Management, analysis, removal, fate and transport of poly- and perfluoroalkyl substances in water.
Water Research Foundation is an internationally recognized non-profit research cooperation that works to advance knowledge in the all areas of the water and wastewater industries, including: asset management, treatment, utility finance and more. This new focus area will work to fund research in the study of PFASs, including their behavior before and after treatment and the identification of sources and hotspots.
CFPUA remains committed to the issue of unregulated contaminants. Committees such as this one work to create new networks of information that will add to CFPUA’s understanding of these compounds, while also allowing us to share our experience and knowledge with others.
We have received the results for November 8 to November 13 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.
