'Assessment of Ground Water Quality Improvements and Mass Discharge Reductions at Five In Situ Electrical Resistance Heating Remediation Sites'

摘要

I read with interest the paper by Dr. Jennifer Triplett Kingston and her colleagues on groundwater quality following Electrical Resistance Heating (ERH) remediation (Triplett Kingston et al. 2012), and would like to offer some clarification on the data and conclusions they present. While this clarification does not change the authors' conclusion that remediation to near groundwater standards is possible and that the spatial extent of the source zone needs to be fully encompassed within the treatment zone, I believe I can shed additional light on some of the operating parameters that lead to complete thermal treatment, and what was actually accomplished by the ERH remediation at the sites they discuss. Also, I believe it will point out some problems with attempting to use mass flux as a measure of what has been accomplished by remediation at sites such as these.
