Mitigating the release of extracellular antimicrobial resistance genes (exARGs) from wastewater treatment plants (WWTPs) is crucial for preventing the spread of antimicrobial resistance from human domains into the environment. This study aimed to evaluate the applicability of intI1 as a performance indicator for securing the removal of exARGs at WWTPs. We investigated the reduction of exARGs and intI1 in a full-scale WWTP, where identical wastewater was treated using conventional activated sludge (CAS) and membrane bioreactor (MBR) systems. The log reduction values (LRVs) for exARGs were lower than those for intracellular ARGs (iARGs) across all ARG species and treatment systems. LRVs for exARGs were consistently higher in the MBR than in the CAS. The intI1 exhibited lower LRVs compared to most exARGs, ensuring a minimum LRV of exARG in both CAS and MBR systems. Consequently, intI1 is an effective indicator gene for securing the removal of exARGs.
