A laboratory modeling system was used to assess the biofouling potential of subsurface amendments. The system described includes the investigations of activities and conditions that lead to clogging of aquifers and well screens during remedial operations. This method was developed to investigate the potential for well and aquifer plugging from using shear-thinning polysaccharides as subsurface amendments. Resultant from initial investigations, several mitigation strategies were developed to both reduce the severity and length of biofouling events. This research demonstrates novel experiments that were used to assess the effectiveness of remedial strategies to prevent the occurrence of biofouling and bioclogging of wells.
