Demonstrating a Biogeophysics Strategy for Minimally Invasive Post Remediation Performance Assessment
Abstract
The three primary objectives of the field demonstration. 1. Identify the long-term geophysical footprint of active bioremediation at a VOCcontaminated site. By so doing, assess of the long-term spatial extent of the altered zone using surface-based geophysical imaging techniques.2. Determine the significance of the geophysical footprint with respect to solid phase mineral transformations and/or biofilms induced by the treatment process. This would enable geophysical alterations within the treatment zone to be interpreted in terms of biogeochemical impacts, which can then be mapped in space and time using geophysical imaging with limited sampling. 3. Demonstrate the use of 1 and 2 above to map gradients in the geophysical footprints of biostimulation along a transect crossing the boundary of the treatment area at an active remediation site and interpret those gradients in terms of long-term biogeochemical impacts.
