General report of TC 215 environmental geotechnics

Twenty two (22) papers have been allocated to this session. They originated from twelve (12) countries and five (5) continental regions (Asia, Europe, North America, South America and Oceania). They described and presented laboratory and field studies and numerical modelling addressing numerous topics which included novel materials, chemical compatibility of barrier materials, unsaturated behaviour of geosynthetic liners, soil-geosynthetic liner interface behaviour, waste geotechnical properties, phytoremediation, permeable reactive barriers, soil and groundwater remediation, image analysis, natural leaching of heavy metals and biogeotechnology. This general report offers a review of all the papers submitted to this session and highlights the major findings reported by the authors of these papers.
