In a limestone single fracture, the biostimulation led to a decrease of 99.2 % in the hydraulic conductivity after 22 days. The testing of monitoring tools, including the modeling of tracer experiments, showed the potential of the groundwater velocity, the planktonic bacteria, the oxidation-reduction potential to provide an insight into the fracture bioclogging. These results suggest that the development of a persistent biofilm, having sufficient hydraulic to significantly alter and groundwater flow in natural fractures in a field setting, is indeed possible"--Abstract. |
