Mineralogical and chemical-physical effects of hydrocarbon permeation in composite liners and cut-off walls. Final report; Mineralogische und chemisch-physikalische Auswirkungen der Permeation von Kohlenwasserstoffen in Kombinationsdichtungen und -dichtwaenden. Abschlussbericht

Abstract

Composite liner systems (HDPE geomembrane and compacted mineral liner) are used in Germany in landfills and for the lining of contaminated sites according to the technical regulations. It is expected that these lining systems provide a highly efficient and reliable technical barrier for the long-term groundwater protection. To support these expectations and assess the performance of the liner system even under extreme conditions, various composite liner systems were exposed to a mixture of 9 liquid hydrocarbons and their permeation behaviour was studied in permeation cells over 12 years. The cells were now dismantled and changes in the liner materials were carefully measured and controlled. The following issues were pursued in the research project: - effect of long-term hydrocarbon permeation and immersion on the properties of the geomembrane, - determination of the vertical distribution of organic contaminants in the mineral liner, - changes in the mineralogical, micromorphological and soil mechanical properties of the mineral liner brought about by the contaminant mixture, - investigation of the influence of microbial activity on the mineral layer, - modelling of the pollutant transport in the composite liner system. Neither geomembrane nor most of the tested mineral liners exhibited significant changes. Hydrocarbon permeation was proved to  More>>

[German] Zur Sicherung von Deponien und Altlasten mit dem Ziel eines langfristig wirksamen Grundwasserschutzes werden seit Mitte der 80er Jahre Kombinationsdichtungen (Verbund aus Kunststoffdichtungsbahn und mineralischer Dichtschichten) eingesetzt. Um deren Langzeitbestaendigkeit auch unter extremen Bedingungen bewerten zu koennen, wurden Permeationsmesszellen, welche die Verhaeltnisse in der Deponie nachstellen und ueber einen Zeitraum von 12 Jahren mit einem Mehrkomponentengemisch konzentrierter organischer Verbindungen beaufschlagt worden waren, zerlegt und die Auswirkungen der Schadstoffpermeation auf die Abdichtungsmaterialien untersucht. Schwerpunkte der hier vorgestellten Arbeiten waren Untersuchungen: - zur Auswirkung der Permeation des Gemsiches an organischen Verbindungen auf die Eigenschaften der Kunststoffdichtungsbahn, - zur vertikalen Verteilung der organischen Verbindungen in den mineralischen Dichtungen, - zu Veraenderungen der mineralogischer, mikromorphologischer und bodenmechanischer Eigenschaften der mineralischen Dichtungsmaterialien, - zu mikrobiellen Aktivitaeten in den mineralischen Dichtungen. Daneben wurden Stofftransportparameter bestimmt und eine Modellierung des Stofftransportes durchgefuehrt. Die verschiedenen untersuchten Materialien der Kombinationsdichtungen erwiesen sich unter den extremen Bedingungen als ein stabiles und effizientes Abdichtungssystem. (orig.)}
