In addition to the on-going pilot tests at Sweeney Water Treatment Plant, CFPUA is also utilizing a test method called an Accelerated Column Test (ACT) to measure the potential of new technologies to treat for compounds such as GenX. The ACT, operated by Calgon Carbon Corporation in Pittsburgh, allows CFPUA to test treatment technologies in shorter periods of time—thereby increasing the potential of receiving actionable data more quickly.
The test, seen in the image on the left, runs water through a type of Granular Activated Carbon to measure its ability to adsorb per-fluorinated compounds. When the carbon becomes full and loses its ability to attract these compounds, GenX will “breakthrough” and be present in test samples. The timeline of “breakthrough” will allow CFPUA to measure how effective this technology may be at Sweeney Water Treatment Plant.
This afternoon, CFPUA received results for the period September 13-18 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.
