What Constitutes Success in the Transfer from the Lab to the Field? (PREPRINT)
Abstract
An operational definition for success at field scale would include meeting regulatory goals for ground water quality in a timely fashion, and at a predictable cost. Current practice for site characterization does not adequately define the amount of contamination subject to bioremediation. As a result, estimates of the requirements for electron acceptors and mineral nutrients, and the time required for remediation, have much uncertainty. In contrast to laboratory studies, the extent of remediation achieved at field scale is influenced by dilution of compounds of regulatory concern in circulated water, and by partitioning of the regulated compounds between water and residual oily phase material. Current practice fails to distinguish reduction in concentration due to dilution and partitioning from reductions caused by biodegradation. Another aspect of success is the capacity to continue to meet regulatory goals for ground water quality after the active phase of remediation is complete. The extent of weathering of residual oily phase materials, and the hydrological environment occupied by the residual, has a strong influence on the potential for ground water contamination after active remediation ceases.
