Assessing chlorinated ethene degradation in a large scale contaminant plume by dual carbon–chlorine isotope analysis and quantitative PCR

Hunkeler, Daniel ; Abe, Y ; Broholm, M.M ; Jeannottat, S ; Westergaard, C ; Jacobsen, C.S ; Aravena, R ; Bjerg, P.L

In: Journal of Contaminant Hydrology, 2011, vol. 119, p. 69-79

The fate of chlorinated ethenes in a large contaminant plume originating from a tetrachloroethene (PCE) source in a sandy aquifer in Denmark was investigated using novel methods including compound-specific carbon and chlorine isotope analysis and quantitative real-time polymerase chain reaction (qPCR) methods targeting Dehaloccocides sp. and vcrA genes. Redox conditions were...

Documentation of time-scales for onset of natural attenuation in an aquifer treated by a crude-oil recovery system

Ponsin, V ; Maier, J ; Guelorget, Y ; Hunkeler, Daniel ; Bouchard, D ; Villavicencio, H ; Höhener, P

A pipeline transporting crude-oil broke in a nature reserve in 2009 and spilled 5100 m3 of oil that partly reached the aquifer and formed progressively a floating oil lens. Groundwater monitoring started immediately after the spill and crude-oil recovery by dual pump-and-skim technology was operated after oil lens formation. This study aimed at documenting the implementation of...

Stable carbon isotope analysis to distinguish biotic and abiotic degradation of 1,1,1-trichloroethane in groundwater sediments

Broholm, M.M ; Hunkeler, Daniel ; Tuxen, N ; Jeannottat, S ; Scheutz, C

In: Chemosphere, 2014, vol. 108, p. 265-273

The fate and treatability of 1,1,1-TCA by natural and enhanced reductive dechlorination was studied in laboratory microcosms. The study shows that compound-specific isotope analysis (CSIA) identified an alternative 1,1,1-TCA degradation pathway that cannot be explained by assuming biotic reductive dechlorination. In all biotic microcosms 1,1,1-TCA was degraded with no apparent increase in the...
