Assessing the natural attenuation of organic contaminants in aquifers using plume-scale electron and carbon balances: model development with analysis of uncertainty and parameter sensitivity

摘要

A quantitative methodology is described for the field-scale performance assessment of natural attenuation using plume-scale electron and carbon balances. Thinks provides a practical framework for the calculation of global mass balances for contaminant plumes using mass inputs from the plume source, background groundwater and plume residuals in a simplified box model. Biodegradation processes and reactions included in the analysis are identified from electron acceptors, electron donors and degradation products present in these inputs.
