Abstract For chlorinated ethenes anaerobic bacterial remediation designs may prove to be the most cost effective measure available to actually reduce the mass of contamination in-situ. In tight and low yield aquifers, the indigenous anaerobic population may be amenable to stimulation by introduction of only small doses of electron donors, or other required growth factors and still produce the desired effects. Anaerobic treatment processes may not require the alteration of the in-situ redox conditions in mixed waste contaminated aquifers, hence the addition of oxygen with its inherent problems and limitations can be avoided. Thus if we can learn to control and harness the reductive dechlorination process in an effective in-situ technology it may have advantages in cost, applicability and operation over existing aerobic bioremediation and physical-chemical treatment methods.
