Log removal of viable cell ARG, fecal indicator and 16S rRNA gene concentrations during treatment of simulated CSO with PAA. Results represent averages ± standard deviation (n=3) or ± maximum and minimum values (n=2). Bold results indicate a statistically significant decrease in genes originating from viable cells was observed from T=0 min (p<0.05).
