Abstract

The paper reports the findings of a comprehensive, laboratory-based characterisation and attenuation study of clay materials from South Wales. Materials studied commonly underlie landfill sites and provide the only means of attenuating and/or retarding leachates, and include estuarine alluvium, weathered Coal Measures mudrocks and glacial till. The laboratory tests conducted include the physicochemical and mineralogical properties of the soils, batch-equilibrium and leaching column tests, the latter two tests involving heavy metal species (Zn2+, Pb2+, Cu2+). Results to date indicate distinctly different characteristics and behaviours due to different geologic materials; higher compacted densities and permeabilities for the mudrocks and glacial till; higher SSA and CEC for the alluvial soils; very high ionic contents for the alluvia; and poor attenuation and buffering capacities of the mudrocks. Clay mineralogy of all soil types tested are more akin to illite+kaolinite.
