Paper Abstract

Solid industrial waste dumps, being an anthropogenic part of the vadose zone, are potential non-point sources of ground water contamination. The early warning provided from qualitative and quantitative information on contaminant migration within a dump is an essential element in monitoring and screening sites for hazardous waste deposition that prevents degradation of recoverable ground water resources and permits to avoid either false positive or false negative errors in evaluation and prediction of the extent of environmental hazards. Multilevel sampling of dump and vadose zone cross sections in the defined points of known waste age and dump construction delivers direct information on vertical distribution of contaminants as a function of time, that is a resultant of a dump and vadose zone hydrogeology, as well as of the mechanism and dynamics of constituent release, interaction and biogeochemical transformation in pore solution. The current presentation describes a procedure for multilevel sampling, pore solution extraction and examination and provides data (vertical profiles of contaminant distribution from a selected landfill site) that exemplify necessity of dump/vadose zone multilevel sampling for correct assessment of contaminants migration rate, understanding processes and conditions affecting contaminant transport, and enhancement of remedial response measures.
