Abstract
A method is provided for locating non-aqueous phase liquid in an aquifer. An aqueous solution having the capacity to solubilize the contaminating liquid to concentrations greater than the solubility of the contaminant in water is injected and produced through a well. Chemical concentrations in produced fluid samples are interpreted to locate the contaminating liquid. Produced fluid samples are chemically analyzed to determine composition of the contaminant.
