Bioremediation

Both in situ and ex situ bioremediation are becoming widely accepted remedial technologies for the treatment of soils and groundwater impacted with recalcitrant contaminants such as chlorinated solvents, perchlorate, wood preserving compounds, pesticides, MTBE, etc.  In situ bioremediation is a broad term that basically describes the process of the treatment of contaminants in place (in situ) via the stimulation of indigenous bacteria or introducing bioengineered bacteria to degrade the contaminants to benign end products either aerobically or anaerobically with little or no waste stream produced.  This includes a range of technologies such as; Air-sparging, Bioventing, In Situ Chemical Oxidation (ISCO), Permeable Reactive Biobarriers (PRBs), Anaerobic Reductive Dechlorination, and Alliances’ own Stimulated Microbial Anaerobic Reduction Treatment (S.M.A.R.T. Technology), to name a few.  Ex situ (generally above ground or “out of place”) bioremediation includes technologies such as; Fixed and Fluidized Bed Bioreactors and Alliance’s own Biocell technology.  Environmental Alliance Inc. has been on the forefront of these aerobic and anaerobic bioremediation technologies for almost ten years now.  We at Alliance understand that each site is different, particularly with respect to the site-specific, rate-limiting factors that are crucial for determining the most appropriate bioremediation strategy.   By understanding and addressing those rate-limiting factors, a remedial strategy can be applied that is both cost-effective and capable of achieving site specific clean up goals in a more timely manner than conventional remedial technologies that is still protective of human health and the environment.
