| Abstract |
A field and laboratory project evaluated the possibility of stimulating a native bacterial population to biotransform carbon tetrachloride (CT) under anoxic conditions. In addition, the transformation of 1,1,1-trichloroethane (TCA), Freon-11, and Freon-113 present as background contaminants in the test zone groundwater were also evaluated. After biostimulation by injection of acetate into a shallow confined aquifer consisting of unconsolidated alluvial sand, the following degrees of transformation were observed: CT, 95%; TCA, 15%; Freon-11, 68%; Freon-113, 20%. These biotransformations were achieved in a biostimulated zone within 2 meters of the injection point. Laboratory and mathematical modeling were also considered. Mathematical modeling of the transport and transformation process confirmed that the behavior observed in the field demonstration was consistent with the results of the laboratory research and theoretical expectations. |
