Heavy metal contamination of water is usually through anthropogenic sources but geogenic sources are also present. Several technologies like reverse osmosis, ion exchange, electrodialysis, adsorption, etc. are used for contaminated water remediation but these technologies have high costs, are energy intensive, and generate harmful sludge as a by-product. In the current scenario, when the world is trying to adopt sustainable practices, the treatment methods that follow a sustainable approach are getting popular. A huge amount of research interest is attracted to finding sustainable approaches to the remediation of water. A sustainable approach offers safer, cleaner, and cost-effective measures for heavy metal remediation from water. The current chapter discusses the methods used for removing heavy metals from water which follows a sustainable approach. The chapter discusses Bioremediation methods and points out the advantages, limitations, and current advancements in these methods.
