Abstract

This paper presents a methodology for evaluating site conditions and for screening various remediation technologies that may be applicable to cleaning up releases of petroleum products from underground storage tanks (UST). The methodology enables the user to develop a conceptual understanding of site conditions before the completion of extensive field studies, define remediation goals, evaluate technologies capable of meeting remediation goals, and identify monitoring requirements during and after remediation.

Working with site-assessment data, the methodology provides an approach for a preliminary determination of petroleum product location in unsaturated and saturated zones and for evaluating the likelihood of pollutant migration within a site's soil matrix. Worksheets then guide the evaluation of how site conditions pertain to factors that favor or inhibit the success of specific technologies.
