remediation techniques for mercury contaminated soil

Mercury soil contamination is an important environmental problem that needs the development of sustainable and efficient decontamination strategies. Mercury soil contamination is an important environmental problem that needs the development of sustainable and efficient decontamination strategies. However, in the absence of organic matter, mercury becomes mobile and evaporates or can leach on to groundwater (1). For the cleanup of non-hazardous mercury-contaminated soils, the approved remediation methodology includes excavation and disposal of contaminated soils at an approved Subtitle D (sanitary) landfill. The technologies addressed in this manuscript include chemical/plant stabilization and volatilization. Controlled thermal desorption … Conventional methods of remediating mercury-contaminated soil – such as adding activated carbon – can be quite expensive to apply on a large scale. Remediation refers to the process of environmental cleanup of contaminated sites and the techniques to reduce or eliminate contamination from soil or groundwater. In Situ Remediation and Stabilization Technologies for Mercury in Clay Soils Cabrejo, Elsa (DOE Fellow), Florida International Univ. Finally, we also discuss the potential challenges and future perspectives for remediation of Hg-contaminated soils. concentrations are less than 4.0 mg/kg. Remediation techniques play a key role in fu lly cleaning up the contaminants in soils and groundwater. Soil sediments actively adsorb the ionic form of mercury, while iron oxides adsorb mercury ions in neutral soils. Remediation pathways include transfer of contaminants alone, or with In soils, mercury remediation can be technically challenging and costly, depending on the subsurface mercury distribution, the types of mercury species, and the regulatory requirements. In soils, mercury remediation can be technically chal- ... mobilization techniques include containment, solidification/ ... mal treatment of mercury-contaminated soil occurs ex situ. Mercury from anthropogenic activities is a pollutant that poses significant risks to humans and the environment. Mercury remediation continues on the South River ... done either through excavating contaminated soil or capping the banks. Bioremediation Contaminated soil is treated in situ by applying engineered aerobic and anaerobic bacterium that feed on the specific type of contaminant that a parcel of soil is contaminated with. Toxicity of mercury However, recent research has found that biochar, a charcoal produced by superheating agriculture or forestry waste in the absence of oxygen, holds promise as a low cost, “green” alternative. @article{osti_1265799, title = {In situ remediation technologies for mercury-contaminated soil}, author = {He, Feng and Gao, Jie and Pierce, Eric and Strong, P. J. and Wang, Hailong and Liang, Liyuan}, abstractNote = {A pollutant that poses significant risks to humans and the environment is mercury from anthropogenic activities. Then, we systematically summarize the soil remediation technologies, including thermal desorption, electrokinetic remediation, soil washing, chemical stabilization, plant and microbial remediation. The IETU is evaluating several potential approaches for managing mercury contamination in soil. Appendix A contains a map … This work is focused on the application of a remediation technique that maintains soil ecological and environmental services to the extent possible as well as search for alternative sustainable land uses. Furthermore, organic matter adsorbs mercury ions in acidic environments. 2. T … In soils, mercury remediation can be technically challenging and costly, depending on the subsurface mercury distribution, the types of mercury species, and the regulatory requirements. Sparging is one of the most common methods of in situ remediation, so this something to consider when looking at a soil remediation method.
