Great visual reminder of why it can be important to revisit our conceptual site models, and consider the influence of stratification and grain size trends on contaminant transport over bulk hydrogeologic definitions
Friedrich Schwille was a pioneer in the study of dense non-aqueous phase liquids (DNAPLs) whose laboratory experiments have inspired generations of scientists and engineers studying groundwater contamination and remediation. In the spirit of his iconic large tank experiments, check out this video of tetrachloroethene (PCE) released into a heterogeneous sand pack in a 1.5 m x 1.5 m x 2 cm glass-walled tank. Great work by Dr. Ariel Nunez Garcia and Brian Moore!
