Fig. 5From: In situ pilot application of nZVI embedded in activated carbon for remediation of chlorinated ethene-contaminated groundwater: effect on microbial communitiesConcentrations of CEs, ethene and ethane in groundwater from wells 14/04 (a), CMT 1 (b) and CMT 2 (c). Left axis represents PCE and the sum of ethene and ethane, while the right axis represents TCE, cDCE and VC. The sum of CE concentrations in a logarithmic scale (d)Back to article page
