Hydraulic conductivity and porosity heterogeneity controls on environmental performance metrics: Implications in probabilistic risk analysis

•Impact of positive porosity-conductivity correlation on probabilistic risk analysis.•Relevance of including porosity variability depends on the metric of interest, the control plane-source distance and the level of conductivity heterogeneity.•A heterogeneous porosity field leads to a reduction of t...
