The investigation of pollutant transfer from waste or soil with leachate into groundwater is of fundamental importance for the assessment of risk potential posed by abandoned waste deposits or other contaminated sites. Following the German Federal Soil Protection and Contaminated Sites Ordinance (BBodSchV, 1999), a leachate forecast is required for the soil-groundwater pathway. The estimation of the pollutant transfer can be performed, among other methods, on the basis of source term strength of contaminated materials determination by laboratory tests.
The leaching behaviour of Polycyclic Aromatic Hydrocarbons (PAH’s) was investigated using column percolation tests and laboratory-scale lysimeter experiments on demolition waste and soil contaminated with PAH’s. The PAH leaching behaviour of the two materials investigated is caused by the different PAH distribution patterns. Both column percolation tests and laboratory-scale lysimeter experiments represent reliable procedures providing data on PAH leaching behaviour. Degradation of potential biologically active materials has to be taken into account.

Die innerstaatliche Umsetzung des Pariser Klimaschutzübereinkommens
- ein Rechtsvergleich

Like all public international law treaties, the Paris Climate Accords rely on national law for their implementation. The success of the agreement therefore depends, to a large extent, on the stepstaken or not taken by national governments and legislators as well as on the instruments and mechanisms chosen for this task. Against this background, the present article compares different approaches to the implementation of the Paris Agreement, using court decisions as a means to assess their (legal) effectiveness.
