Surfactant Enhanced Aquifer Remediation

Lower mobility contaminants can prove difficult to recover from an aquifer by conventional pump and treat techniques. However, recovery can be optimised by re-injecting treated waste water with additives, such as surfactants, to flush contaminants though the aquifer.

Additives may dissolve the contaminant, increasing its mobility within the groundwater, enabling recovery using conventional pump and treat techniques.

A steep hydraulic gradient forms between the injection point and abstraction point, forcing groundwater to flow between the two, resulting in rapidly accelerating clean up and controlling the groundwater regime, and preventing the escape of mobilised contaminants.
