2 Chemical desorption from soil and sediment is of central importance to most environmental concerns including remediation. Des-orption affects chemical fate, toxicity, and associated risk to human and aquatic life as well as the efficiency of most remediation technologies. Desorption is commonly mod-eled as a reversible partitioning process in fate, risk, and remediation models. However, the r...

Results are presented for a hypothetical problem involving remediation using therm...

Sampling scheme design is an important step in the management of polluted sites. It largely controls the accuracy of remediation cost estimates. In practice, however, sampling is seldom designed to comply with a given level of remediation cost uncertainty. In this paper, we present a new technique that allows one to estimate of the number of samples that should be taken at a given stage of inve...

Soil and surface water contamination by used lubricating oil is a common occurrence in most developing countries. This has been shown to have harmful effects on the environment and human beings at large. Bioremediation can be an alternative green technology for remediation of such hydrocarbon-contaminated soil. Bioremediation of soil contaminated with 5% and 15% (w/w) used lubricating oil and a...

The remediation of contaminated soil and groundwater is essential toward the development of a sustainable society. However, remediation activities at various stages will also inherently add a significant burden of environmental footprints. Green remediation is thus increasingly recognized in the recent years by various regulatory agencies, responsible parties, remediation engineers, and various...

Trivalent Cr is one of the heavy metals that are difficult to be removed from soil using electrokinetic study because of its geochemical properties. High buffering capacity soil is expected to reduce the mobility of the trivalent Cr and subsequently reduce the remedial efficiency thereby complicating the remediation process. In this study, geochemical modeling and migration of trivalent Cr in s...

Soil and surface water contamination by organic compounds is a common occurrence in most developing countries. This caused harmful effects on the environment and human beings. Bioremediation can be an alternative green technology for remediation of such hydrocarbon-contaminated soil. Bioremediation of soil contaminated with 5% and 10% (w/w) diesel fuel amended with 10% soy cake (SC), potato ski...

Results from an innovative approach to improve remediation in the rhizosphere by encouraging healthy plant growth and thus enhancing microbial activity are reported. The effect of arbuscular mycorrhizal fungi (Am) on remediation efficacy of wheat, mungbean and eggplant grown in soil spiked with polyaromatic hydrocarbons (PAH) was assessed in a pot experiment. The results of this study showed th...
