Since August 2017, CFPUA has been conducting a pilot study at the Sweeney Water Treatment Plant to investigate the potential to remove per-fluorinated compounds from the treated water.
During this study, we collected data on the number and levels of per-fluorinated compounds in the plant and compared it to levels measured after filtration through different treatment technologies. In turn, we used that data to evaluate the effectiveness of various kinds of granular activated carbon and ion exchange media to remove the contaminants.
Black & Veatch, the engineering firm contracted to assist us with this effort, has submitted a final report dated April 30, 2018, on their findings.
Staff is currently working to analyze these findings and will use the data to present a recommendation for future action to the CFPUA Board of Directors.
In July 2017, CFPUA installed a water station in Ogden Park to provide water free of per-fluorinated compounds such as GenX to residential customers. The water station is open every day, from 8 am to 8 pm, and is free of charge.
To allow for better access to the station, CFPUA has moved it to a new location across the street from its previous position. The station is marked by a CFPUA banner and can be found near the tennis courts parking lot.
We have received results for April 11 and April 17 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 parts per trillion (ppt).
