Source Area Treatment

Anaerobic bioremediation is contaminant specific and will result in either the destruction or immobilization of the target contaminants.  By continuously eliminating or immobilizing contaminants within the source area, migration of ground water contaminants may be effectively prevented.  Ideally, the entire pore volume of the source area would be filled with a dilute mix of Newman Zone®.  However, many successful projects have replaced as little as 10% to 30% of the source area.

Most of the contaminant mass in source areas is either adsorbed to soils or is physically captured within pores as free product.  Injection of large volumes of amendment has the potential to locally mobilize contamination within the source area.  A site-specific injection plan should balance the need to distribute the amendment within the source area without mobilizing contamination moving it from the source area.  Such a plan could include placement of a down-gradient permeable reactive barrier.
