Abstract:

One of the major limitations to the effectiveness of in situ bioremediation is that performance is dependent on effective amendment delivery. However, practitioners generally have little knowledge of the subsurface distribution of amendments and there is often substantial uncertainty about whether treatment design criteria have been met, or if and where and when additional injections are required. Such uncertainty is either addressed through dense sampling, or through overly conservative remedial efforts, both of which are costly. The performance objectives of the technology demonstration were to show that automated electrical geophysical monitoring can be used as an alternative to existing methods to provide timely, volumetric and cost effective information on spatiotemporal behavior of amendments used in enhanced bioremediation. These objectives included quantitative and qualitative measures. Quantitative measures were formulated in terms of spatial resolution, temporal resolution, and data-processing timeturnaround. Qualitative measures pertained to timely delivery of actionable to scientistsengineers in the field, and the ability of geophysical monitoring to map amendment behavior.
