Project Summary (1995-2000)

This project is studying the hypothesis that the combined effect of toxic concentrations of metals and organics in soil can result in decreased bacterial biomass and activity, and inhibit bioremediation of that soil by indigenous organisms. The two major objectives of this project are to evaluate the bioremediation potential of metal/organic contaminated soils using indigenous bacteria as biomarkers, and to investigate the influence of heavy metals on the ability of bacteria to degrade organic contaminants. Biomarker assays developed in this project will be used to document changes in the soil microflora following additions of contaminants to soil in field scale lysimeters.
