Reductive dehalogenation of chlorinated ethenes to the non-toxic end-products ethene and ethane is used for nearly 20 years and it is considered for the most efficient and frequently used remediation method. However, in some localities the initially successful transformation is halted to cis-DCE and carcinogenic VC, and the reason for the incomplete reduction.
Main objective of the project is to design, test, and verify a technology for assessment and support of the complete elimination of chlorinated ethenes from ground water. Additional output from the research activities will be the use of a novel molecular biology approach in exploring of the reductive dehalogenation of chlorinated ethenes during remediation activities and establishing a multidisciplinary evaluation table with key parameters and values which can help to predict a stagnant or complete reductive dehalogenation. The criteria table could serve as an easy guide for remediation companies and will be a helpful directive for control authorities and state administration during evaluation of the remediation efficiency.
