Abstract |
There are three lines of evidence used to support natural attenuation as a remedy for chlorinated solvent contamination in ground water. They are (1) documented loss of contaminant at field scale, (2) geochemical analytical data, and (3) direct microbiological evidence. Microcosm studies are often used to provide a third line of evidence. The potential for biodegradation of the contaminants of interest can be confirmed by the use of microcosms, through comparison of removals in the living treatments with removals in the controls. Microcosm studies also permit an absolute mass balance determination based on biodegradation of the contaminants of interest. Further, the appearance of daughter products in the microcosms can be used to conform biodegradation of the parent compound. |
