MTBE: a conservative tracer for estimating biodegradation and hydrodynamic dispersion at underground storage tank sites.

摘要: Methyl tertiary-butyl ether (MTBE) is a fuel oxygenate added to gasoline in the United States. At release sites, MTBE can be used as conservative tracer evaluate contaminant transport processes. A three-dimensional evaluation of dissipation groundwater contamination was performed at an automobile repair facility following excavation contaminated soil. This entailed installing clusters multilevel sampling probes using direct-push methods flow and distributions three dimensions. data were estimate mass by advection dispersion. permitted determining benzene toluene lost biodegradation estimating rates. For comparison, rates determined more traditional inverse modelling. The modelling calibrate analytical model for hydrodynamic dispersion coefficients. Source concentrations based on calibrated model.
