Popis:	Understanding differences in source zone natural attenuation (SZNA) rates occurring among field sites impacted by the same contaminant and across field sites impacted by different contaminants is critical for developing management strategies. For example, unique site conditions can favor or inhibit biodegradation, whereas differences between contaminants can lead to variations in biodegradation potential. However, the implications of these effects for real-world release scenarios remain ambiguous. To better understand the implications of these effects, the authors investigated differences in SZNA rates at two crude oil and two denatured fuel-grade ethanol (DFE) spill sites using on-site measurements of surficial gas effluxes. At the crude oil sites, CH4 effluxes were below detection, whereas CH4 effluxes occurred at both DFE sites. Similarly, SZNA rates among sites impacted by the same contaminant were comparable, whereas order of magnitude differences existed between sites impacted by crude oil o...
