Analytical inverse modeling of regional-scale tritium waste migration

In this study, a regional-scale tritium (³H) plume resulting from waste injection at the Idaho National Engineering Laboratory (INEL) is analyzed using an analytical model. Values of transverse dispersivity, source width, contaminant velocity, and effective source concentration are determined in an independent fashion using the model. The reproducibility of the plume in general and of concentrations at selected wells with these values is acceptable to good, and the values obtained for transverse dispersivity and contaminant velocity in particular are reasonable in light of other regional-scale studies.
