- •
NA of TPH and enhanced bioremediation of TCE were observed within a TPH plume.
- •
TPH can serve as a primary substrate and enhance the reductive dechlorination of TCE.
- •
Natural attenuation could effectively contain the TPH plume and cause TPH removal.
- •
Substrate is the main limiting factor for the occurrence of TCE dechlorination.
- •
Dehalococcoides can be used as a biomarker for the feasibility of TCE dechlorination.
