The following white paper provides an abbreviated overview of two laboratory experiments and a fieldwork demonstration that showed evidence for the biodegradation of contaminants from CAC.
The colloidal activated carbon (CAC) technologies developed by REGENESIS, PetroFix and PlumeStop, are often paired with biostimulating electron acceptors or donors to destroy adsorbed contaminants.
The draft standards from the Government of Canada rely on EPA testing methods 533 or 537.1, but still apply to 'any' per- and polyfluoroalkyl substance.
