ABSTRACT:
The present invention relates to methods for improving hydrocarbon-water compatibility. More specifically, the invention relates to methods for enhancing the production of surface-active agents in hydrocarbon-exposed surface waters in order to improve hydrocarbon-water compatibility. Hydrocarbon-exposed surface waters having enhanced levels of surface-active agents can be used to improve remediation of subsurface hydrocarbon-contaminated sites.
