Intrinsic and stimulated in situ biodegradation applied in in-situ treatment zones at sites contaminated with hexachlorocyclohexane (HCH)

The pollution of soil and groundwater with hexachlorocyclohexane (HCH) has caused serious environmental problems. Mineralisation of some HCH isomers can be expected under aerobic conditions whereas all isomers are known to be bioconverted to intermediate products under anaerobic conditions. Hence, redox conditions can be expected to have strong...
