Abstract

Electrokinetic Treatment of Mercury Contaminated Soil at the Mercury Refining Company Superfund Site

Author(s): Lusk, R. ;  Bricka, R.

Mercury contamination due to leakage from industrial processes can result in serious environmental, health, and safety concerns. Traditional methods for the remediation of elemental mercury from contaminated sites include a dig and haul approach (retorting) and/or an isolation approach. However, these methods can be very costly and ineffective with regards to removing the mercury from the contaminated soil. Therefore, a new Electrokinetic Remediation method is proposed in which mercury can be cost effectively removed from a contaminated site in order to be recycled or disposed of properly. This method includes the use of anodes and cathodes installed in the ground throughout the contaminated site to produce an electric field which forces the contaminant to migrate to a specific position in which it can be efficiently removed. The use of several amendments to increase the solubility (and electrokinetic potential) of the mercury in the soil is also researched to determine a most effective and efficient mercury removal scheme. It was determined in batch and continuous electrokinetic cells that a 0.1 M Potassium Iodide, .01 M EDTA was effective in solubilizing and removing mercury below the EPA’s regulatory limit of 31mg/kg.

Workshops

Responsible Site Design: Implementing Innovative Stormwater Management Strategies

The primary goal of the workshop is to create a dynamic learning experience that examines the role of stormwater management in the built environment. The workshop will focus on integrating ecologically sound water management approaches into site design. After the workshop, attendees will be familiar with the following concepts and technical issues:

  • Knowledge of the stormwater treatment chain
  • Knowledge of the impact of land use codes on stormwater management
  • Application of a design process that mitigates the effects of stormwater on-site
  • Knowledge of the relationship between land use codes and design for innovative stormwater management
