INTRODUCTION & BACKGROUND

The widespread contamination of the subsurface by non-aqueous phase liquid (NAPL), such as

organic solvents and other hydrocarbons, presents a significant health risk due to the potential

exposure to contaminated ground water. Conventional pump and treat technologies have proven to

be an ineffective and costly means of aquifer restoration. To overcome theçe limitations,

mobilisation of residual NAPL has been proposed as both a promising and cost effective

alternative.
