Surfactant enhanced aquifer remediation

Lower mobility contaminants can prove difficult to recover from an aquifer by conventional pump and treat techniques. To overcome this issue, our in situ flushing technique effectively re-injects treated waste water with additives, such as surfactants, to flush contaminants through the aquifer.

Additives 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. This results in an accelerated clean up and prevents the escape of mobilised contaminants. This, paired with 20 years of experience in ground remediation, ensures the delivery of an efficient and cost-effective service every time.
