Update on CFPUA’s Efforts to Address the Issue of Emerging Contaminants

An Update on CFPUA’s Efforts to Address the Issue of Emerging Contaminants

CFPUA is committed to addressing the challenge presented by emerging contaminants. To do so, action must be taken on several fronts: treatment technology, testing methods, chemical research and legal action. CFPUA has ongoing efforts and partnerships in all of these areas and, today, we would like to provide a summary of the progress we have made thus far and an idea of where we will go in the future.

  1. The pilot study at Sweeney Water Treatment Plant continues in its second phase of testing. The pilot study has investigated the potential of multiple types of Granular Activated Carbon and Ion Exchange media to remove emerging contaminants such as GenX. Black & Veatch, the firm contracted to assist CFPUA with the study, expects testing to be completed this Spring. Black & Veatch provides monthly updates on the study’s findings and, once the study is complete, this data will be used to form a recommendation on technological updates to Sweeney Water Treatment Plant’s filtration systems.
  2. CFPUA samples the treated water from Sweeney Water Treatment Plant on a weekly basis for GenX. Despite increased levels of GenX measured at the Chemours Outfall 002 in December, we have seen the levels in our treated water consistently stay below the NCDHHS health goal of 140 parts per trillion.
  3. Our partnership with the University of North Carolina Wilmington continues. Staff maintains an active dialogue with the team at the University working to identify other emerging contaminants in the river. We receive monthly updates on their progress and incorporate their findings into our work at the Sweeney Plant.
  4. CFPUA continues to meet its obligations under House Bill 56. We share findings from our pilot study with Brunswick and Pender Counties on a monthly basis, and we will provide a final report to the Environmental Review Commission by April 1, 2018.
  5. We continue to be involved in on-going litigation with Chemours and Dupont, and we will update the public on the progress of our legal action as it moves forward.
