Sustainable Remediation Technologies

Lab based tank to measure performance of insitu groundwater remediation technologies
Surface monitoring of an air sparging system at work

The application of known technologies to new scenarios can provide an added impetus to technology development alongside promotion of market uptake of these improved applications.  The use of geophysical techniques has recently been reapplied to monitor a variety of subsurface environments (groundwater, contaminant plumes and microbial activity).

This project applies geophysical techniques to active groundwater remediation technologies (air sparging and pump and treat) using a series of lab and field tests.  Active groundwater remediation technologies are energy intensive and this energy requirement is sustained for the life of the remediation.  Therefore active technologies are less sustainable in terms of cost-efficiency, contamination reduction and environmental balance.

Geophysics techniques provide decision-making methodologies to increase the efficiency of active remediation technologies.  This will optimise the need for subsurface drilling, reducing energy consumption and making active remediation a more practicable and sustainable option.
