Current studies include development of bioaugmentation cultures for chlorinated ethenes that grow at low pH, evaluation of bioremediation strategies to treat high concentration of halogenated methanes, use of biostimulation to enhance biogeochemical degradation of chlorinated ethenes in fractured sandstone, and studies to determine the anaerobic biodegradability of 1,4-dioxane.
