At the former landfill Pill in Tyrol, Austria groundwater contamination was caused by high Ammonium loads of up to 20 mg/l. Biodegradable nitrogen was specified as the cause of groundwater pollution by ammonium. However, other substances were hardly noticeable. Ammonium is generated within the landfill body through anaerobic decomposition of organic matter.
In this case an in-situ aeration of the landfill was planned to oxidize biodegradable nitrogen compounds. This securing system with the best price/performance ratio was selected as part of a comparison of concepts based on the emission prognosis. If the organic available nitrogen within the systemis degraded, an anaerobic conversion of the existing carbon compounds with the formation of ammonium is no longer possible. The special feature is that the in-situ aeration was planned in such a manner, that the unsaturated zone and the landfill body behave like a biological fixed-bed reactor. The landfill surficialarea itself represents a biofilter for any escaping pore-air. Through a network of a total of 216 wells, the landfill area of approximately 18 ha is supplied with air.

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.
