Abstract Biodegradation is a cost-effective tool in the remediation of persistent
organic pollutants but can take place only when the concentrations of toxic substances are decreased to levels suitable for microbial growth, i.e., after nZVI
application. Assessment of the impact of nZVI on indigenous microbial communities is, therefore, an essential step in designing a successful remediation strategy.
Here, we summarize the most common microbiological methods for monitoring the
effect of nZVI on microorganisms such as the cultivation of bacteria, fluorescence in
situ hybridization (FISH), phospholipid fatty acid (PLFA) analysis, real-time PCR,
and sequencing.

34.1 Introduction
The high efficiency of nZVI in reducing persistent organic pollutants in aquifers is
well known. The application of this highly reactive material inevitably influences
indigenous microbial communities. These communities can adapt to harsh conditions in polluted environments and often utilize present pollutants for their metabolic
