Publisher's Synopsis
In landfilling technology, it is accepted that the soil substrate underlying the landfill can be used as a physical and chemical buffer (i.e. to accumulate and attenuate contaminant leachates emanating from the waste pile) . This places a great responsiblity on the landfill constructor to determine correctly the capability of the soil substrate to perform its buffering funtions. This book covers the physico-chemical processes which control the transport of aqueous and nonaqueous phase liquids in soils, and aims to provide a viable and reliable transport model for accurate forecasting of transport performance of contaminant plume for the time period of concern.
