IN SITU BIO-REACTOR (ISBR) CASE STUDY
- Old oil spill (1994 release) beneath a historic structure (constructed in 1839).
- Two oxygen release compound injections failed to achieve and sustain remedial compliance.
- Chemical oxidation injection failed to sustain acceptable levels due to tight soils and source location
- Stable Isotope Probing (SIP) was used to evaluate the impacts of the in situ chemical oxidation on the indigenous microbial organisms. Short term bio-stimulation observed after chemical oxidation event, but not sustained.
- Sustainable aerobic bio-stimulation was achieved through the installation of a novel, In Situ Bio-Reactor (ISBR).
