IN SITU BIO-REACTOR (ISBR) CASE STUDY

Site Background

  1. Old oil spill (1994 release) beneath a historic structure (constructed in 1839).
  2. Two oxygen release compound injections failed to achieve and sustain remedial compliance.
  3. Chemical oxidation injection failed to sustain acceptable levels due to tight soils and source location 
  4. 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.
  5. Sustainable aerobic bio-stimulation was achieved through the installation of a novel, In Situ Bio-Reactor (ISBR).
