dc.description.abstractMine tailing and lake sediment from a former mining area in Canakkale (Turkey) were analyzed for physical (e.g. moisture content, particle size, specific gravity, and hydraulic conductivity) and chemical parameters (e.g. organic content, pH, ORP, and EC) as well as heavy metal content and sequential extraction analysis, in an attempt to evaluate their risk as a source of contaminants. Column extraction tests were conducted to investigate the leachability under model field conditions using simulated rainwater. The toxicity characteristic leaching procedure (TCLP) and synthetic precipitation leaching procedure (SPLP) methods were performed to evaluate the expected concentrations in the water in contact with the solid material. The results showed that both tailing and sediment in the study area were highly acidic (pH=2.2-2.92) and electrical conductivities were high. The column tests proved that Fe and Pb can be released to the waterbodies in contact with the solid materials. Pb was released easier than Fe due to its content in the more labile fractions in the sequential extraction analysis. SPLP-Pb in both tailing and sediment exceeded the U.S. EPA regulatory limit confirming the hazardousness of those materials. All of these results were used to evaluate the most appropriate remedial strategy and to recommend phytocapping as a practical green and sustainable method to mitigate the environmental risk.
