Grant: Applied Research and Development Grants - Level 2

Soil remediation by electrokinetics is an emerging technology that has shown positive results for fine textured soils. In an effort to find new technologies that require less soil movement, reduce operational intensity, and minimize distances travelled, our industry partner has identified electrokinetic (EK) remediation as an enabling technology that may allow for responsible and sustainable remediation of soil and groundwater. Although the technology has shown promising results at small scale, the company aims to optimize the technology and make it cost-effective for large scale implementation. The goal of the present project is to understand how to implement EK remediation and to demonstrate if there is a repeatable treatment trend for salt-affected soil. *Specific objectives to be achieved include:*1) Development of a cost effective EK remediation technology for large scale implementation that includes integration of a remote operating and monitoring system,*2) Assessment of the effect of soil moisture content on the efficiency of EK remediation, and*3) Assessment of the impact of electrokinetics on soil microbial population.*Four research centres at NAIT will collaborate and partner with the company to achieve these objectives. The successful implementation and optimization of EK technology would allow for significant cost savings for oil and gas companies in Canada and reduce the environmental impact observed with current practices by minimizing surface soil disturbance and removing the need for movement of contaminated soils. The interdisciplinary nature of this project will provide stimulating and strong training for all NAIT and company technical staff and students involved in field and lab activities. Research findings will also be widely shared to field practitioners through regional conferences and workshops on land remediation and reclamation
