Iron contamination in potable water systems presents a persistent challenge, often exceeding regulatory thresholds and compromising public health. This review delineates the geogenic and anthropogenic drivers of iron mobilization in groundwater, followed by a comparative assessment of physicochemical methods; limited by cost, selectivity, and scalability. In contrast, iron-oxidizing bacteria (FeOB), notably from the Proteobacteria phylum, offer redox-mediated bioremediation pathways with enhanced sorption potential and biofilter adaptability. The review has emphasised on FeOB’s operational feasibility, integration with real-time monitoring, and alignment with BIS and CPCB standards. The review advocates for translational frameworks to deploy microbial technologies in decentralized water treatment systems. © 2025 The Author(s).
