Quantification of natural attenuation of the contaminant

Is my plume degrading ?

Groundwater flux measurements allow quantifying the actual degradation of the pollutant plume between two control panels.

Based solely on pollutant concentration data, the calculation of this parameter is impossible because a decrease in concentrations could be attributable to a dilution of the plume, but not to its degradation.

By calculating mass fluxes, we can easily quantify this degradation
