Application of electrochemical oxidation for the enhancement of antibiotic resistant bacteria removal in stormwater bioretention cells

Antibiotic resistance in urban stormwater: a review of the dissemination of resistance elements, their impact, and management opportunities

“…A 3.68-log reduction in the concentration of the E. coli K-12 strain with the RP4 plasmid carrying bla TEM , tetR, and aphA was achieved in a bioretention cell under control conditions. 115 Similar removal rates for ARGs were recorded in an additional bioretention cell, though the removal was ARG dependent; the removal ranged between 5-7-log for aphA and 2-7-log for bla TEM and tetR under the different experimental conditions. 116 Slightly lower removal rates were observed for the ermB (2.5-log) and sul1 (0.9-log) ARGs in a pilot-scale stormwater biofilter that received a synthetic stormwater and sewage mixture.…”

“…116 Removal of ARGs was able to be enhanced from 3.68-log to 5.28-log when electrochemical oxidation was applied to the soil environment. 115 GSI systems being able to remove ARGs from urban stormwater runoff indicates a potential management opportunity for the public health crisis of antibiotic resistance. The minimal research in this field however leads to no conclusive understanding as to the capability of GSI to serve a long-term role in mitigating the transport of ARGs via urban stormwater runoff and the governing design factors.…”
