Determining In Situ Degradation Rates for Petroleum Compounds via Push-Pull Tests under Natural and Biostimulated Conditions(Abstract)

摘要

Remedial technologies often are selected based on chemical or geochemical trend data, without specific knowledge regarding the existing site-specific natural attenuation capacity at the site. Push-pull tests are a novel investigatory technique that were utilized to determine site-specific natural attenuation capacity (bio-degradation rate kinetics) under both una- mended and amended (biostimulation) conditions. The analytical results produced from the push-pull tests allow for the segregation of abiotic versus the biotic (biological) com- ponents of the in situ degradation rates, thereby creating a process to determine if the biological component of the degradation rate is significant versus abiotic processes such as dilution and absorption.
