In particular, the removal of PFAS contamination through adsorption onto activated carbon has been a key focus. In the 9 months it has been deployed, Bygen's GAC has shown extremely strong adsorption capabilities for the measured PFAS chemicals, with continued retention of the PFAS within the activated carbon over this period of time evident. Total PFAS concentrations within the GAC used in this trial increased from non-detectable levels initially to over 1000 ng/g during sampling at the 8-month stage of the project. In comparison, biochar supplied at the same time only demonstrated an adsorbed total PFAS concentration of 100 - 200 ng/g, which was comparable to native plant species in the area.
