Abstract |
Rising groundwater levels in
Bitterfeld, Germany, will transport organic contaminants near the ground
surface in the future, so that the construction of near-natural wetlands may
present an effective remediation approach. A 2 × 6 m pilot
plant was built to investigate the fate of monochlorobenzene (MCB), one of the
main pollutants at the site, in a wetland system. MCB concentrations were
reduced from ~10–15 mg l-1 at the inlet to ~1–3 mg l-1 after
passage through the soil filter. A zonation in the vertical and horizontal
direction was apparent for MCB, sulfate, iron(II) and pH. Aerobic MCB-degrading
microbial communities were enriched from the pilot plant and showed degradation
of MCB in microcosms down to oxygen-limited conditions of 0.5 mg O2 l-1.
Volatilization may also constitute a significant process as indicated by the
results of active and passive gas sampling at the surface of the soil filter.
Overall, constructed wetlands have a high potential for the remediation of
chlorinated solvents, but more research is needed to move away from a black box
approach and understand the relevant attenuation processes.
