摘要: A permeable reactive barrier (PRB) was installed during 2005/2006 to intercept, capture and degrade a fuel spill at the Main Power House, Casey Station, Antarctica. Here, evaluation of performance PRB is conducted via interpretation total petroleum hydrocarbon (TPH) concentrations, degradation indices most probable number (MPN) counts heterotroph degrading microbial populations. Results indicate that locations which contained lowest TPH concentrations also exhibited highest levels numbers microbes, based on MPN methods selected. This provides insights appropriate materials for use in PRB’s cold nutrient-limited environments.
