OEPA Acknowledges C8 Filtration Breakthroughs

Despite an earlier denial, Ohio EPA has confirmed that C8 has broken through local filtration systems on at least six occasions.

On June 6, The Anchor reported that C8 was still making its way into some local water supplies even after the installation of filtration systems intended to remove the unregulated manmade substance. C8, also known as PFOA or perfluorooctanoic acid, became a source of controversy in the Mid Ohio Valley when it was detected in six local water supplies – leading to a class action lawsuit against DuPont and a landmark health study intended to determine whether or not exposure may cause human disease.

In response to the public health concern, DuPont constructed industrial scale filtration systems for the impacted water districts based on carbon filtration – meaning that the efficiency of the filtration is dependent upon timely and fresh change outs of carbon filtration material.

Despite the installation of technology intended to reduce the concentration of C8 in local water supplies to non detectable levels, sampling results obtained from the EPA in May revealed that small but measurable amounts were breaking through some of the filtration systems – an indication that in some locations carbon change outs are not being performed frequently enough to prevent breakthroughs.

C8 Detected in Filtered Water

Despite the installation of technology meant to filter C8, very small amounts can still be found dripping from the taps of households served by some Mid Ohio Valley water systems.


Sampling results obtained from the EPA reveal that small but measurable amounts of the controversial manufacturing chemical routinely break through some of the filtration systems. DuPont has provided the means to reduce the concentration of C8 to non detectable levels, but the court mandated process lacks regulatory oversight.
