Abstract
Field estimates of the mass discharge (mass/time) from
contaminated sites are increasingly being used in contaminated site management and a quantification of the uncertainties related to such estimates are therefore of great practical importance. We present here a comprehensive
approach for quantifying the uncertainty in the mass discharge across a multilevel control plane. The method is based on geostatistical inverse modelling and accounts for i) conceptual model uncertainty through multiple
conceptual models and Bayesian model averaging, ii) heterogeneity through Bayesian geostatistics with an uncertain geostatistical model and iii) measurement uncertainty. The method is tested on a TCE contaminated site for which four different conceptual models were set up. The mass discharge and the associated uncertainty are hereby determined. It is discussed which of the conceptual models is most likely to reflect the true site conditions.
