A long-term field study explored nanoscale zero-valent iron (nZVI)-driven degradation of chlorinated ethenes supported by electrokinetic (EK) treatment which positively affects nZVI longevity and migration, and its impact on indigenous bacteria. In particular, the impact of combined nZVI-EK treatment on organohalide-respiring indigenous bacteria, ethenotrophs, and methanotrophs was assessed using molecular genetic markers detecting Dehalococcoides spp., Desulfitobacterium spp., the reductive dehalogenase genes vcrA and bvcA and ethenotroph and methanotroph functional genes.
