Understanding contaminant transport to model and quantify bioremediation in the microbial filters project
- Univ. of Wisconsin, Madison, WI (United States)
The efficacy of in situ bioremediation remains difficult to quantitatively demonstrate. One aim of the microbial filters project is to evaluate the in situ bioremediation of chlorinated ethenes such as trichloroethylene (TCE). To meet this need, a downhole treatability tool was developed to enable us to assess field biodegradation applications. A tracer lab experiment run in a column of the downhole treatability tool combined with tracer data analyzed from a microbial filters field test were used to understand the flow of water through porous media in the lab and in the field. A spreadsheet template was written to evaluate the contaminant transport equations and predict breakthrough curves of the tracer and TCE. The resulting tracer curve correlated well with experimental data and will lay the foundation for experiments performed with bacteria to assess the extent of bioremediation.
