What is Bioremediation?

Using subsurface microorganisms to transform hazardous contaminants into relatively harmless byproducts, such as ethene and water

  • Biodegrade
  • Mineralize
  • Biotransform

Techniques or types of bioremediation:

A component of Natural Attenuation
Enhanced Bioremediation
Bioaugmentation

Bioremediation Background

Natural Attenuation is Not fast enough, Not complete enough, Not frequently occurring enough to be broadly used for some compounds, especially chlorinated solvents
The current trend is to stimulate/enhance a site’s indigenous subsurface microorganisms by the addition
of nutrients and electron donor
In some cases, bioaugmentation is necessary when metabolic capabilities are not naturally present.

Sources of Contamination

Industrial spills and leaks
Surface impoundments
Storage tanks and pipes
Landfills
Burial areas and dumps
Injection wells
