Objective:

Permeable barrier technology is potentially advantageous for chlorinated solvents because it circumvents the high energy, operational, and maintenance costs associated with long duration remediations (e.g., pump and treat) resulting from subsurface geology diffusion phenomena. In addition permeable barrier technology not only can prevent plume migration, but can destroy contaminant(s) rather than transporting or transferring them as either air or water based mass removal techniques do (e.g., pump and treat or air sparging).

The potential impact of biological reactions on the treatment of PCE and TCE by zero-valent iron permeable barriers in the field is recognized by many investigators. However, most of the discussion is speculative or even contradictory with respect to what the impact will be since bioactivity could conceivably be either inhibitory or beneficial to overall removals. The impact of biological phenomena on permeable barriers has recently been observed in the UCF labs. The proposed research is aimed at quantifying the impact of biotic activity on barrier removals and kinetic rates to allow biotic phenomena, which will be unavoidable in many full-scale settings, to be more explicitly accounted for in permeable barrier design.

The proposed objectives are (1) to quantify detrimental or beneficial effects of biotic reductive dechlorination, occurring within a zero-valent iron barrier, on its performance, and to try to identify the mechanisms causing the effect (e.g., biofilm covering active surface, pH changes, ORP changes, biotic reductive dechlorination of PCE or TCE as well as production or dechlorination of daughter products which may have significantly different half-lives, and (2) to develop a model calibrated using the kinetic information generated in the lab to investigate without experimentation the different sequences and combinations possible between abiotic and biotic reductive dehalogenation. In addition, any potential beneficial coupling of permeable barrier technology with bioremediation technology will be investigated since this has been proposed by others but remains undeveloped.

Approach:

To accomplish this research, four parallel columns (10 cm in diameter, l m in length) will be filled with abiotic concrete sand/iron and biologically active soils with and without iron, respectively. Samples will be analyzed for PCE, TCE and daughter products using gas chromatography. One biologically active column will be selected inhibited to identify critical microbial types (i.e., methanogens, sulfate reducers, etc.). Microcosms will also be constructed from materials from biologically active columns.

Expected Results:

Results will serve as model inputs to permit simulation of various remedial scenarios.
