TL;DR: Overall, reproducibility and agreement with theory of column tests are better than batch tests, presumably because the latter are prone to artefacts (e.g. in liquid-solid separation steps).

TL;DR: New and improved existing methods for groundwater risk assessment are developed and used to derive a new regulatory concept for the upcoming "Decree for the Requirements of the Use of Alternative Mineral Building Materials in Technical Constructions and for the Amendment of the Federal Soil Protection and Contaminated Sites Ordinance" of the German Federal Ministry of Environment.

TL;DR: Assessment of the longevity of the PFAS agricultural sources and compare standardized column percolation tests to long-term leaching of PFAS from contaminated sites indicate that complete removal of these compounds will likely take years to decades to occur, which is expected from results of the column leaching tests.

TL;DR: Abstract Reply to the comment by D. Guyonnet, on “Comparison on percolation to batch and sequential leaching tests: Theory and data”.

TL;DR: In this article, the authors investigated dispersive processes that diminish contaminant concentrations originating from an unsaturated source zone on the way to groundwater, using the numerical model MIN3P for a nonvolatile, nondegrading contaminant from a persistent source after reaching a steady state.
